TWERGO Reduces Costs of Overexertion Injuries, Gets More Parts on Carts

December 7, 2021

Billions are lost every year due to overexertion injuries. It’s Time for Twergo.

Both the direct and indirect costs associated with back and shoulder injuries are staggering and are a huge drain on resources and productivity.

The Ohio State University’s Spine Center offers this sobering example. Based on an OSHA study, it was estimated that the indirect costs alone of lower back pain in 2014 dollars came to $62 billion.  In this example, if you spent $100 every second, it would take you nearly 20 years to spend what the U.S. loses in one year from the indirect costs of low back pain.

Push Force is the Biggest Offender.

The most common culprit behind these injuries deals with the amount of force required to push or pull wheeled equipment, This force is always greatest at the start. Once the cart is rolling, it typically requires less effort to push or pull. Taking these two factors into consideration, when the starting force and rolling force exceed those that the operator can safely push, injuries occur.

Twergo™ Caster Wheels Shoulder Injuries, Saving Company Thousands

Heavy Duty Casters The use of Twergo™ Caster Wheels from Caster Concepts has been extremely cost-effective in terms of reducing worker injuries. Recently, Twergo Caster Wheels were used at a large aviation company to reduce the push and pull forces of carts averaging 1,000 lbs. Even at this weight, injuries were mounting, with the average shoulder injury costing $55,000 and the average back injury costing $28,000.

The results of using 6” x 2” Twergo Wheels are shown below, with push and pull numbers (in terms of force) measured before and after installing Twergo Wheels. Carts weighed 1,000 lbs. apiece.

TWERGO is Caster Concepts’ patented, ergonomic caster wheel featuring Twin- and Triple-wheel designs that have independently spinning wheels.  These wheels can rotate in either direction and at any rate, minimizing friction when turning and maneuvering. The benefits include reduced initial and continuous push force, as well as the force exerted to turn.

TWERGO Wheels Helps Electric Vehicle Manufacturer Reduce Push Force Below 35 lbs. on Manual Carts

In another relevant example, a major electric vehicle manufacturer needed to get the maximum push force below 35 pounds on their manual carts to reduce overexertion injuries and increase productivity. These carts were carrying loads of 1500 pounds. At a push force weight below 35 pounds, 99% of the workforce can move a cart multiple times per day, per shift.

After trials with a variety of caster manufacturers, Caster Concept’s 8×2 Twergo wheels were chosen and were the only wheels that passed their strict standards.

TWERGO Ergonomic wheels are great for AGV’s and Tuggers where high weight capacities are needed. They are reliable at higher speeds and are available in two-and three-wheel configurations.
