New Side-Steer Powered Cart Handles Long Parts

Long parts or equipment that overhang the ends of the cart have always been a challenge to move. Objects that overhang the transport cart make it impossible for operators to safely push or pull loads from the end of the cart; they just can’t get physically close enough to get a safe handhold or exert proper force. Overhanging loads are generally too heavy to be pushed or pulled by a single worker and their length makes maneuvering these loads particularly awkward and unsafe. Problems with reach length, load balance and load stability even make use of traditional motorized tuggers unproductive and unsafe. The length and cumbersome placement of oversized loads makes it impossible for tuggers built to handle normal loads to safely reach under an oversized product or piece of equipment to grab and connect to the cart, much less guarantee safe transport and maneuvering by the operator.

DJ Products, the nation’s foremost manufacturer of ergonomically-designed motorized carts and powered cart movers, has solved the problem of safely transporting oversized loads with the introduction of its new side-steer powered cart. The unique side-steer design of this self-propelled cart allows the operator to safely walk behind and to the side of oversized loads, providing clear sight lines and safe, easy maneuvering of heavy, extra-long parts and equipment no matter how far they overhang the transport cart. Visit our website to watch a video of DJ Products’ new side-steer powered cart in action.

Capable of hauling loads up to 5,000 pounds, DJ Products’ ergonomic design ensures that the cart, not the worker, shoulders the load. The conveniently-located variable-speed twist grip is designed to reduce the risk of carpal tunnel syndrome while easily allowing the operator to move forwards and backwards at speeds up to 3 mph. Ergonomic design allows workers to perform their jobs more efficiently and comfortably by allowing equipment to be adjusted to the size of the worker. Awkward and unsafe work postures that lead to tired and cramped muscles, longer and more frequent work breaks, and disabling musculoskeletal injuries are eliminated.

The National Institute for Occupational Safety and Health (NIOSH) reports that one worker in every 200 experiences an overexertion injury. Annually, overexertion injuries cost American businesses more than 12 million lost work days and over $1 billion in compensation costs. According to a study published in the New Hampshire Business Review, every dollar invested in ergonomics reaps a $4 savings in medical, insurance, workers’ compensation and lost work day costs. To find out how DJ Products’ new side-steer powered cart can safely maneuver overhanging loads and save you money, talk to one of our ergonomic specialists today.

Star Trek’s Vision of Material Handling Flawed

The legendary television show Star Trek and the franchise’s many spin-offs brought the future to the present. Many of those futuristic gizmos sparked the imaginations of young inventors resulting in tools, electronics and appliances that are commonplace today. So I was surprised to see what looked suspiciously like an ordinary forklift truck creeping along the space dock floor in the newest Star Trek movie. Of course, the good news is that the material handling industry appears to be alive and well in the 24th century. However, with their staggering accident and injury rate, you’d think that engineers of the future would have come up with a more efficient, more cost-effective, more ergonomic tool for moving material and equipment from place to place than antiquated forklifts.

This is one place where the generally forward-thinking minds who envision the Trek universe got it wrong. Even in our century, forklift trucks are already on their slow way out. Spurred by safety issues and high operating and maintenance costs, a growing number of savvy business and industry leaders are choosing to replace their forklifts with safe, fuel-efficient, ergonomically-designed, motorized material handling carts and movers. A few centuries from now, I can envision sleekly-designed material handling movers gliding silently on cushions of air above the floor surface, either completely automated or guided by shiny robots; but primitive forklifts? Surely the material handling industry will have progressed beyond that old dinosaur by then!

Companies that have replaced their forklift trucks with ergonomically-designed motorized carts are already realizing decreased accident/injury rates and enjoying the accompanying significant savings in medical, insurance, worker’s compensation and disability costs. Every year forklift accidents are responsible for 100 worker deaths — 25% from overturns — and more than 20,000 injuries. Ergonomically-designed CartCaddies promote operator control and safety with their walk-behind design, strategically placed ergonomic controls, and easy maneuverability.

And when it comes to maintenance costs, sure to be a factor when you’re building mega-trillion dollar starships, battery-operated CartCaddies win over forklifts hands down. The average annual battery/maintenance cost of operating an ergonomic electric CartCaddy is around $300 per year. Compare that to forklifts where operating and maintenance costs comprise 80% of the total cost of ownership over the life of a unit. Annual forklift fuel costs alone can run from $15,000 for gas and diesel units to $3,000 to $8,000 for electric and battery-operated units.

Why Are Ergonomics Important?

We’ve been getting back to basics in our last couple of posts on the history of ergonomics and ergonomic terms, reviewing what ergonomics is for those new to our blog. But why are ergonomics so important in the workplace? Three reasons:

  1. Ergonomics improves worker health and safety.
  2. Ergonomics increases productivity and work quality.
  3. Ergonomics saves money.

Health & safety. People come in all shapes and sizes, but until the advent of ergonomics, material handling equipment was one size fits all. Except the problem was that it didn’t fit all people. Workers taller or shorter than the fictional “average man” to whose size and shape equipment was designed had to reach and stretch or hunch and bend to reach and manipulate equipment controls, to load and off-load product or materials, or to push and pull carts from one work station to another. All that stretching and scrunching around puts stress on the body’s muscles, joints and tendons. Backs become sore, arms and legs tire more quickly, and neck and shoulder muscles start to ache. At first the body heals itself, repairing minor muscle tears, but repetitive stress simply doesn’t allow enough time between exertions for the body to heal. Muscles, tendons and joints can be damaged. Called musculoskeletal injury, this damage can become permanent over time, resulting in permanent disability.

Ergonomics addresses this problem through flexible, adjustable design that allows equipment to be adjusted to the size of each individual worker, ensuring ideal positioning and maximum operator comfort during work tasks for every worker. A national leader in the manufacture of ergonomically-designed motorized carts, DJ Products incorporates a host of important ergonomic features into its material handling products, including:

  • Heavy-duty, battery-operated motors easily move loads up to 50,000 pounds, removing the need to physically push and pull carts.
  • Scissor lifts quickly position materials at the proper height for each individual worker.
  • Well-positioned ergonomic twist-grip hand controls prevent carpal tunnel syndrome by minimizing wrist movement.
  • A variable-speed feature incorporated into the twist grip allows operators to safely control cart speed between 0 and 3 mph while moving either forwards or backwards.
  • A conveniently placed safety stop switch permits instant stops in case of emergency.
  • Added weight over the drive tires creates greater traction, allowing the handling of heavier loads.
  • A specially designed connecting arm allows loads to pivot a full 180 degrees, ensuring safe turning without jackknifing.
  • Walk- or ride-behind equipment construction provides clear sight lines for safe operator control.

Financial rewards reaped by employing ergonomics

How Ergonomics Increases Productivity and Quality

In our last post we talked about how ergonomically designed material handling equipment improves worker health and safety by reducing expensive and potentially debilitating musculoskeletal injury. Business owners also realize measurable increases in worker productivity and product quality when ergonomic equipment and procedures are introduced into the workplace.

Most industrial equipment and work procedures were originally designed for occasional use, not the high-pressured, repetitive, long shifts found in the modern work place. By designing equipment that adjusts to the physical size and capabilities of each individual worker and by structuring work procedures to eliminate uncomfortable body positions during task performance, ergonomics decreases fatigue on muscles while increasing worker comfort. This enables workers to continue working comfortably without the frequent breaks they would otherwise need to stretch and rest tired muscles. Workers remain fresh and energized and can work comfortably through an entire shift. The result is decreased injury, better worker morale and increased worker productivity resulting in improved product quality. Ergonomics produces a win-win scenario for business owners and their employees.

Implementation of an effective ergonomic plan requires a three-pronged approach that involves engineering, administration and work practice modifications.

  • Engineering modifications may include changes in equipment and tools used, workstation modifications and changes in the way tasks are performed. Because engineering modifications produce the greatest reduction or elimination of physical risk, they also result in the greatest cost savings. Reduced physical risk reduces the medical, insurance, disability and lost man-hour costs of potentially debilitating musculoskeletal injury. On its website, DJ Products provides an invaluable Ergonomic Load Calculator that can be used to estimate the force needed to move loads in a variety of workplace environments and recommend ergonomic solutions to your material handling problems.
  • Administration modifications involve alterations to the work organization and/or workplace culture. While less expensive to implement, results are also less reliable in that they depend entirely on human compliance. Administrative modifications may include education and training in ergonomic procedures, restructuring job responsibilities to minimize repetitive tasks, worker/task rotation, increasing the frequency or duration of break periods for certain tasks, improving workers’ physical conditioning and developing oversight programs.
  • Work practice modifications include the development of ergonomic procedures for the performance of each individual task, worker training and oversight.

The initial investment in ergonomics may seem to be considerable, but the benefits — and long-term savings — far outweigh the costs and continue long after the initial investment is recouped.

Monday: How ergonomics saves money

How Ergonomics Saves Money

Musculoskeletal injuries caused by overexertion are responsible for 25% of all workplace injuries and affect one in every 200 workers, according to data compiled by the National Institute for Occupational Safety and Health (NIOSH). Overexertion injuries caused by straining during pushing, pulling, lifting and carrying tasks cost U.S. businesses more than $1 billion in compensation costs and 12 million lost workdays every year. But that’s just the tip of the iceberg! According to the National Council on Compensation Insurance, more than 50% of worker’s compensation claims are for debilitating back injuries that affect 1.75 million (1 in 5) workers each year — at an annual price tag of $30 billion. The time-lost cost of a single back injury is estimated by the Bureau of Labor Statistics at $26,000.

Ergonomic equipment is designed to eliminate and prevent muscle strain, overexertion, back injury and the whole gamut of musculoskeletal and repetitive motion injuries that eat away at U.S. business profit margins. Ergonomically-designed equipment reduces the risk of overexertion and injury from pushing, pulling, lifting, carrying, bending and twisting tasks. The equipment, not the worker, carries the burden, eliminating expensive medical, insurance, worker’s compensation and lost work-hour expenses. When workers are less physically tasked and workplace safety is increased, worker morale improves, production increases and product quality goes up.

One study of U.S. manufacturers found that every dollar invested in ergonomics resulted in a savings of $4. DJ Products, a national leader in the manufacture of ergonomically-designed carts and movers, has found that most customers recoup their investment in ergonomic equipment within the first year. DJ Products specialized in providing affordable ergonomic solutions to material handling applications. We manufacture material handling equipment that is designed to eliminate the strain and pain of manually pushing or pulling heavy carts, equipment or materials. Our ergonomically-designed equipment is smaller, more maneuverable and less costly than traditional material handling equipment such as forklifts, walkies and motorized riding tugs. DJ Products specializes in battery powered, walk behind carts, movers and pushers that offer maximum safety and maneuverability.

Staying Competitive as Recession Wanes

The economy is finally showing signs of life; although as we mentioned in our last post, recovery is likely to be a slow process. As America recovers from the recession, businesses may find themselves trapped between wary consumers on one side and skittish bankers on the other, further slowing economic recovery. A continued lag in spending and lending means that belt-tightening will remain the norm for at least the next six to 12 months if businesses are to stay competitive and, in some cases, survive.  

In an informal poll conducted last month, Manufacturing & Technology eJournal readers said they planned to rely on a variety of cost-cutting measures over the next year to maintain their competitiveness (click the link above for complete survey results):

  • 36% expand territory
  • 32% seek cost reductions from existing vendors
  • 24% eliminate underperforming products/services
  • 24% employee layoffs
  • 21% reduce salaries or work days
  • 12.5% seek work closer to home

Turning to your own workers for suggestions on how to increase cost-saving measures has proved a successful tactic in many industries during the recession. While concessions made by auto workers and airline employees have garnered the lion’s share of the headlines, workers in nearly every industry and business field have agreed to cut salaries, decrease work hours or forego benefits in order to maintain the solvency of their employer and keep their jobs.

It’s all about sharing the load and allowing workers to buy into the decision-making process. Workers express greater support for solutions they have helped create. And they’re more likely to embrace cost-cutting measures — and exert peer pressure on fellow employees to toe the line — when they feel:

  1. Their efforts will have a direct impact on solving the problem.
  2. More people will be able to keep their jobs because of the sacrifices they are making.
  3. The burden is being shared equally by workers and management.  

That last point may be the most critical. We’ll look at why next time.

Using Ergonomics to Increase Employee Diversity

In this space we’ve often extolled the value of ergonomics and ergonomic equipment. Ergonomically-designed material handling equipment like DJ Products’ CartCaddy motorized carts and tugs offer multiple benefits in the workplace, including:

  • Reducing worker injuries and ensuring a safe work environment
  • Improving worker morale by decreasing physical stress and strain during task performance
  • Decreasing medical, insurance and worker’s compensation costs
  • Decreasing time-lost costs due to worker injury and recovery/rehabilitation
  • Increasing productivity, efficiency and profitability

But as Anne Kramer, CEO and President of Ergo Works, Inc., pointed out in a recent article posted on DiversityBusiness.com, ergonomics also opens the workplace to a more diverse workforce by improving accessibility.

Ergonomics is the science of fitting the task to the worker, rather than forcing the worker to contort his body to perform the task. Ergonomic design recognizes that workers come in all sizes of varying physical ability. Recognizing the great diversity among workers, ergonomic design allows equipment to be positioned and used by a maximum number of workers. 

Ergonomic equipment is designed to minimize the overexertion or cumulative trauma of manual lifting, pushing, pulling, stretching and other repetitive tasks that can injure soft muscle tissues. Kramer notes that back and shoulder injuries account for one-third of all missed work days. When the burden of a task is assumed by the equipment instead of the worker’s back, the need for inappropriate exertion is eliminated and the risk of injury is reduced. Ergonomics allows a more diverse group of workers to perform the same task or use the same piece of equipment, keeping injury rates low and productivity high. Use of ergonomic equipment allows employers to satisfy their legal responsibility to accommodate workers, maximizes use of their workforce and reflects a commitment to diversity in the workplace.

Two Factors Have Greatest Impact on Ergonomic Risk

Frequency and duration are the two factors that have the greatest impact on ergonomic risk. In developing or reviewing your company’s ergonomic plan, pay particular attention to the frequency and duration of tasks that stress the musculoskeletal system. Reducing the frequency or duration of these tasks will significantly decrease the incidence and severity of musculoskeletal injuries in your workplace. When not addressed, the frequency and duration of tasks that strain workers’ musculature or skeletal system have been proven to significantly increase the risk and expense of long-term injury and loss of function.

It makes sense that the more frequently a worker is required to perform a pushing, pulling, lifting or carrying task that causes overexertion or strain, the greater the risk of musculoskeletal injury. In fact, the repetitive performance of a task over time takes a similar toll on the body, even when muscle strain is not involved. The longer a worker is required to perform a task — duration — also increases the risk of injury. Interestingly, researchers at the National Safety Council have found that the presence of multiple ergonomic risk factors — as few as two — has a multiplicative rather than an additive effect on the likely development of musculoskeletal injury.

The following actions have been found to effectively reduce the risk of musculoskeletal injury in the workplace:

  • Decreasing the number of risk factors present in the workplace. Ergonomically-designed carts, tugs, scissor lifts and similar material handling equipment can be used to perform manual tasks that involve pushing, pulling, lifting and transporting, taking the burden off workers, reducing injury risk and improving productivity.
  • Providing sufficient recovery time between task sessions. Providing rest breaks allows muscle recovery between work sessions. Rotating workers through a variety of tasks limits their risk exposure. But the most productive solution is utilization of ergonomic material handling equipment that enables repeated performance of a specialized task without injury risk.

What’s Stress Got to Do with It?

When we think about work stress we tend to focus on its impact on our daily job: cost overruns that threaten to push our project over budget, smoothing the ruffled feathers of a fellow employee, meeting sales projections, etc. But stress comes from multiple sources. There’s mental stress from trying to accomplish a goal, emotional stress from interacting with fellow workers, and physical stress resulting from overexertion. We’re human which means that stress is a daily occurrence, particularly in this economy. The problem is that chronic stress can affect performance — both mental and physical, decreasing effectiveness and productivity.

A new study published in the July issue of the journal Science shows that chronic stress actually rearranges the wiring in our brain. In a study with rats conducted jointly by the U.S. National Institutes of Health and researchers at the University of Minho in Portugal, stressed rats lost the ability to make effective decisions. Effective decision making, whether in the performance of mental or physical tasks, requires humans to choose the most productive option from a field of choices. When stress is unrelieved, people are more likely to make poor decisions. In the study, the portion of the brain associated with goal-directed behavior shrank while the area that controlled habit formation grew. Under perpetual stress, people, just like the rats in the study, lose the ability to make smart decisions and fall back on old habits.

Physical stress from overexertion, overreaching or cramped work platforms were as debilitating in eroding decision-making ability as emotional or mental stress. Interestingly, physical stress accelerated the erosion of mental abilities faster than other kinds of stress. Pain and discomfort seem to act more quickly on human stress thresholds than mere mental irritation. Utilizing ergonomically-designed material handling equipment is one smart way to decrease employee stress.

Ergonomic Carts Can Help Struggling Hospitality Industry

Staycations and a sharp decline in business travel during the recession have pushed the U.S. hospitality industry to the edge. In recession for the past 24 months, overall occupancy rates continue to erode despite a slight seasonal uptick in June. Occupancy rates at U.S. hotels, motels and resorts have been falling even more rapidly than before over the past eight weeks and the immediate future doesn’t look good, according to industry watcher Hotelmarketing.com.

Continued concern about family finances and potential job loss have kept families at home. Group travel is down, and tours are being cancelled for failure to meet minimums. Businesses have cut travel to hold the line on expenses. Convention and trade show attendance is down. Hotels and motels are competing for a narrowing traveler pool that has forced many to cut staff until the economy improves and the hospitality industry rebounds.

Savvy hoteliers are turning to ergonomically-designed hospitality carts that allow a single employee to accomplish a greater workload with less physical effort. Ergonomic design eliminates strains and pains that workers can develop from pushing heavy laundry, cleaning and linen carts at hotels, motels, casinos and resorts. Powered housekeeping carts and clean and dirty linen carts allow a single employee to safely manage heavy loads of linens or cleaning supplies.

Powered platform carts and electric carts allow easy and safe movement of supplies, materials, parts or machinery from one area of a facility to another. Compact design permits operators to easily and safely maneuver carts through heavily traveled hotel corridors and narrow behind-the-scenes hallways. Motorized dump hoppers makes trash removal a breeze.

DJ Products, the national leader in the manufacture of ergonomic motorized carts and tugs, offers a full line of material handling products designed to meet the needs of the hospitality industry. Our motorized cart retro kit can be adapted and installed on any cart to increase safety and productivity. Visit the DJ Products website for more information.
