Effect of a load shape on load acceleration at the start of an electric hoist

Abstract

This contribution describes the effect of a load shape on load acceleration at the start of an electric hoist. The emphasis is on a comparison of acceleration course of loads. Two loads with entirely different shape-a load with a cuboid shape and one with a cylinder shape, were chosen. Improved mathematical theory for the start of an electric hoist with three degrees of freedom is used. Thus, we measured the acceleration of the electric hoist, the wire rope end and the load center of gravity for two loads with different shape.
