Use Ergonomics to Improve Lifting Safety

Lifting and carrying are the two material handling tasks that result in the greatest number of worker injuries each year. (See our May 14 post on tips for ergonomic carrying.) Applying ergonomics to material handling tasks that involve lifting reduces the need for reaching and bending and the injury-producing stress those actions can place on the back and shoulders. Ergonomics also strives to reduce the amount of effort and force necessary to perform lift tasks.

Calculations of lift force involve both the amount of weight to be lifted and the time period over which the average worker can lift that weight without risk of developing lower back pain. Under ideal conditions, the maximum weight a typical healthy worker can lift with two hands over an 8-hour period is 51 pounds, according to the National Institute of Occupational Safety and Health (NIOSH). However, a number of variables can significantly reduce the maximum lift weight. 

To decrease the potential risk of injury from lift tasks, both overall work flow and individual work tasks should be evaluated to eliminate unnecessary lifting. Where lifting is necessary, ergonomically designed equipment can be used to facilitate many lift tasks. Workers can also be trained to use ergonomic principles in performing lift tasks to minimize potential injury.

To decrease injuries caused by lifting, follow these suggestions:

  • Use ergonomic electric scissor lift tables and power hoists to lift and lower loads where possible to minimize manual lifting.
  • Minimize the distance materials must be lifted or lowered.
  • Use adjustable powered tugs that allow workers to position lift loads at the appropriate height for maximum lifting power.
  • Tag unstable or heavy loads to alert workers. Promote team lifting of such loads to minimize potential worker injury.
  • Test loads for weight and stability before lifting.
  • Reduce load weights and balance loads to facilitate lifting without injury.
  • Rotate workers between lifting and non-lifting tasks or have workers alternate lifting with non-lifting tasks to avoid over-straining muscles. 
  • Reduce the frequency of lifting and amount of time workers perform lifting tasks.
  • Provide clear access to materials to be lifted to prevent awkward reaching, bending and twisting during lifting.
  • Provide secure grips on materials to be lifted.
  • Provide sufficient foot traction with the floor to increase worker stability during lifting.

DJ Products is Team Cart Caddy

DJ Products is one of the top manufacturers of electric and motorized material handling solutions. Our new website demonstrates all the reasons why we’re Team Cart Caddy, and why you should be too.

Our goal is to provide you with material handling options that are safe and ergonomically designed while remaining cost-effective. They’re so easy to use that they can be handled by a single person, leaving your other employees free to work on other duties.

The relatively compact size of our movers along with their generous range of movement allow for more effective maneuverability, even in tight spaces. Your employees will find them to be more convenient and manageable than traditional equipment like fork lifts. As a result, they’ll use them more frequently which results in greater productivity and fewer workplace injuries.

Team Cart Caddy offers a selection of pushers, pullers and tugs to accommodate a wide variety of applications. Simply click on “Industry” on the menu at the top of the page to locate your specific requirement. “Applications” gives you images of our products in actual workplaces. Select “Products” to view a complete listing.

If you can’t find your industry or you’re unsure about the best solution for your application, our friendly, knowledgeable Sales Engineers are ready to assist you. Call 800.686.2651 to speak with them directly or submit a question on our website. For additional convenience we also have a handy online chat feature.

Electric Tuggers Improve Ergonomics in Material Handling

Improving the ergonomics of material handling decreases worker injuries, improves workplace efficiency and leads to a healthier bottom line. Medical costs, insurance premiums, workers’ compensation payments and lost man-hours soar when ergonomics are ignored. Material handling is one of the most injury-intensive industries, according to the U.S. Department of Labor. Every effort you make to fit the demands of work tasks to the capabilities of your workers (i.e., ergonomics) will decrease costs and ultimately improve profit margins.Material handling requires many actions that can result in serious and expensive musculoskeletal injuries. Repetitive motions, awkward postures and the application of force as workers lift, push, pull, carry and handle materials create daily opportunities for injury. Attention to ergonomics in designing tasks, workspaces and equipment can dramatically decrease the physical demands and injury potential of many material handling activities.Carrying and lifting are the two actions that present the greatest potential for worker injury when handling materials. Today we’ll address tips for ergonomic carrying; on Friday, we’ll share tips for lifting ergonomically.Carrying tasks place stress on the back and shoulders and create contact pressure on the shoulders and hands. When repeatedly strained or overstressed, the effort and force needed to carry materials can cause injury. To decrease injuries caused by carrying, follow these suggestions:

  • Eliminate unnecessary carrying.
  • Minimize the distances materials must be carried and use electric tuggers to carry materials over longer distances.
  • Organize work tasks so that physical demands and work pace increase gradually as muscles warm up.
  • Rotate workers or alternate carrying with non-carrying tasks to prevent overstraining the body and give muscles a chance to rest between efforts.
  • Wear properly fitting gloves to improve grip stability.
  • Reduce load weights and test loads for stability and balance before carrying.
  • Slide, push or roll materials. These actions place less stress on the body than carrying.
  • Use conveyors, slides or chutes to move materials.
  • Use electric tuggers to transport heavy loads.

Efficient Wheel Design Reduces Friction

Friction occurs when two surfaces come into contact, as when a wheel rests on a floor. Friction is the force that resists movement between the objects. Under theoretically perfect conditions, the ideal wheel environment would be a hard, smooth wheel rolling over a hard, smooth surface. In real life, perfect conditions never exist. In a typical work environment, using a hard wheel will often result in higher rolling resistance, as well as increased noise and vibration.

Both static and dynamic forces affect friction. The initial push force necessary to place an object in motion is the static force. Static force is generally greater than dynamic force which is the exertion necessary to keep the object moving. Wheel design must consider bother static and dynamic force.

In a wheel or caster system, there are three places where friction can affect force:

  • at the point where the axle and wheel interface;
  • if a swivel caster, in the swivel housing; and
  • at the ground/wheel interface, particularly at any points where the wheel will slide or pivot on a surface.

The efficiency of a wheel or caster in reducing friction is dependent not only upon the appropriate design of the wheel itself, but also on the materials used in its construction and the placement of the wheels on the equipment to be moved.
