The United States Air Force needed to replace casters for aircraft maintenance stands used to change windows on military aircraft’s. The carts were hard to roll, requiring a significant amount of force exertion. The replacement casters had to withstand the environmental challenges that are caused by outdoor use, including humidity, rain water, high heat and other such challenges.
Create a caster that can reduce push force, while supporting the weight capacity and overcome the environmental challenges.
A completely aluminum caster, with a custom top plate and modified polyurethane tread formulation.
Push force was reduced noticeably, the Technical Sergeant in charge of acquisition stated “They are 10 times easier to move around the aircraft”. In addition, aluminum resists corrosion, ensuring consistent performance and longer use life.
