TWERGO® Wheels Spark Initiative to Get Push Force Below 35lbs. at Electric Vehicle Manufacturer.

 The Problem:

A major electric vehicle manufacturer needed to get the maximum push force below 35 pounds on their manual carts. These carts were carrying loads of 1500 pounds. 

It was essential for the company to meet the 35-pound push force standard. At that weight, 99% of the workforce can move a cart multiple times per day, per shift (See Chart A). And that meant maximum efficiency. Another important reason to lower push force is that one overexertion injury can cost a company $20K, which adds up quickly when injuries begin to mount. 

 The Solution: Caster Concept’s 8×2 Twergo wheel.

Heavy Duty Casters

The company performed trials for many different caster manufacturers in the marketplace. Caster Concept’s Twergo® wheel was the only one that passed their standards. 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.

Workplace Injuries and Push Force

With more concerns revolving around workplace safety, the most common culprit behind injuries deals with the amount of push force. The force required to push or pull wheeled equipment 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.

CHART A:  Push Force Industry Risk    
70 LBS. PUSH FORCE SAFE FOR 38% OF POPULATION 62 OUT OF 100 AT RISK FOR INJURY 
50 LBS. PUSH FORCE  SAFE FOR 82% OF POPULATION 18 OUT OF 100 AT RISK FOR INJURY 
40 LBS. PUSH FORCE   SAFE FOR 90% OF POPULATION 8 OUT OF 100 AT RISK FOR INJURY 

 

Heavy Duty Casters

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.
