DJ Products, Inc. is the world leader in providing assist tugs and a battery powered cart puller to the manufacturing, hospital, and retail markets. They provide cart puller solutions that eliminate the pains and strains associated with manually pushing hospital beds and heavy carts. 
A large hospital in California just partnered with DJ Products, Inc. to help provide solutions for eliminating possible injuries from moving all wheeled loads, including beds, gurneys, food and linen carts. After evaluating many push and pull devices and companies, they chose DJ Products Cart Puller for their superior product design and custom solutions.
Employees pushing these heavy carts are of an aging workforce, so ergonomics and safety are of a bigger concern. Strains, pains, and injuries due to over-extending the body can become very costly on employers. Cost conscious ergonomic and safety equipment, like the CartCaddyLite Cart Puller, when used for prevention can easily pay for themselves almost immediately.
The CartCaddyLite Cart Puller can easily maneuver food carts in tight areas up to 1500 lb. The puller has a variable speed cart twist grips that allows the operator to travel at speeds of 0-3 mph forward or backward. With its compact, 24-volt motor being powered by 2 12v batteries, the Cart Puller can perform without re-charging for an entire shift.
