Caster City says better casters can cut warehouse push-pull injuries

Caster City is highlighting how the wheels under warehouse carts can drive worker strain, with better-specified casters reducing push force and helping facilities lower injury risk. The company points to ergonomic, industry-matched casters as a practical fix for warehouses, healthcare, food service and lab environments.

Why it matters: - Push-and-pull injuries remain a major warehouse safety issue, especially when workers have to start loaded carts moving. - The National Institute for Occupational Safety and Health estimates work-related musculoskeletal disorders cost U.S. businesses between $13 billion and $54 billion a year. - Overexertion from pushing, pulling, lifting and carrying accounts for roughly a quarter of all non-fatal occupational injuries in the U.S. - Reducing breakaway force can lower strain on shoulders, lower backs and wrists.

What happened: - Caster City released guidance on reducing push-and-pull injuries in warehouses by improving the casters used under carts and mobile equipment. - The company focused on how caster design affects breakaway force, rolling resistance and worker effort. - Torrey Stephenson, president at Caster City, said facilities that upgrade to properly specified ergonomic casters typically see push force requirements drop by up to 50% on loaded carts.

The details: - Breakaway force is the strain required to get a stationary cart moving, and that moment is described as the most dangerous part of a push. - Cracked concrete, uneven floors and debris increase the effort needed to move carts and can raise injury risk. - Worn or undersized wheels increase rolling resistance, forcing workers to rely more on muscle than momentum. - Caster City says its ergonomic casters use polyurethane wheels to reduce rolling resistance and absorb shock from cracked concrete, expansion joints and ramps. - The casters use extended swivel leads to reduce steering effort and allow full 360-degree rotation. - Sealed precision bearings in both the wheel and swivel sections are designed to preserve low resistance over time by keeping out dust and debris. - Stainless steel casters in 304 grade are positioned for general washdown areas and food service floors. - Stainless steel casters in 316 grade are built for harsher chemical exposure and marine-grade corrosion. - Food-safe polyurethane wheels are aimed at catering lines and food production floors with strict hygiene requirements. - Total-lock brake casters lock both the wheel and the swivel at once, which is important in healthcare and lab settings where equipment must stay fully still during use.

Between the lines: - The message is not just about comfort. It is about removing a common source of avoidable strain before workers get injured. - The guidance frames caster selection as a safety control, not just a maintenance decision. - OSHA already recognizes pushing and pulling heavy loads as an ergonomic hazard employers are expected to manage. - Matching casters to the floor, load and environment can reduce one of the variables that pushes strain back onto workers. - A wheel audit is a lower-cost fix than the disruption and paperwork that follow a workers' compensation claim.

What's next: - Warehouses and other facilities can review cart fleets, floor conditions and load demands to identify casters that are underspecified or worn out. - Employers that upgrade casters before injuries occur may be able to reduce strain and improve compliance with workplace safety expectations. - Caster City is positioning itself as a supplier of industrial casters, wheels and mobility solutions for healthcare, food service, cleanroom and heavy-duty manufacturing applications. - The company says it has more than four decades of experience providing guidance on caster selection for safety, ergonomics and operational efficiency.

The bottom line: - In many facilities, the fastest way to reduce push-and-pull strain may be the simplest: check what is rolling under the load.
