Maneuvering a utility cart can be hard on your body. When you're pushing, pulling or turning a heavy cart to get it where it needs to be, your joints are subject to compression, torque and shearing forces. Over time, this may lead to lower-back pain, knee strain or other musculoskeletal disorders (MSDs).
Good ergonomic practices can help prevent MSDs for people who push or pull carts as part of their work. Regardless of the type of cart you choose, these four tips are a great place to start:
Experience Counts
These four tips are a great place to start, but keep one thing in mind: there's no replacement for experience.
Studies have found that experienced workers have better technique when they push and pull carts, reducing the strain on their bodies and helping to reduce the risk of injury.
Research cited in Safety and Health at Work found that experienced workers create a hinge movement that allows them to lean in against the weight when pushing and to lean back against the weight when pulling. However, the researchers could not determine whether good technique can be taught to inexperienced workers or whether it comes only from long-term hands-on experience doing the work.
Q: What kind of maintenance do utility cart casters and wheels need?
A: Many manufacturers recommend regular preventive maintenance for utility cart casters and wheels, typically including steps such as these:
Consult the caster manufacturer for more maintenance procedures.
Q: What's the best height for a utility cart handle?
A: There's no single best handle height that will work for every person in every situation. A person's ideal grip will likely change depending on their height and how they're maneuvering the cart—whether they're pushing or pulling it, for example. Research published in Safety and Heath at Work recommends that handles should allow for a variety of grip positions between a person's hip and shoulder height.
Q: Is it better to push or to pull a cart?
A: Pushing is sometimes recommended as a better alternative to pulling when both are possible. For example, an OSHA ergonomics e-tool for electrical contractors recommends that pulling be avoided when possible. However, in 2017, researchers reviewed many studies and found that there's evidence to support a preference for either pushing or pulling, depending on which strain factor is being focused on. In other words, pushing and pulling put different kinds of strain on the muscles and joints, and there isn't enough evidence to support a blanket preference for one over the other
Q: What factors influence how difficult it is to push or pull a cart?
A: The weight of the load has the biggest influence on how physically taxing it is to push or pull a cart, but there are other factors to consider:
Changes in any of these areas can help improve the overall ergonomic design of the work.
