Conveyor pulley a hub and bushing on lower tension pulleys. The shell is also referred to as the rim in some parts of the world. The pulley shaft is typically sized following CEMA B105.1 in the Americas or AS 1403 in Australia. Pulley manufactures in Germany (DDR) in 1962 included Zemag, Lauchhammer, and Köthen.

Wire rope spooling technology pattern is engineered to suit the rope's length, diameter and construction type. In any multi-layer spooling application it is important that when the rope is first installed on the drum, it is done so under tension to avoid any slack on inner layers that can be crushed or nicked against the groove walls by outer layers. The fleet angle is defined as the largest angle of the rope between the first sheave and the drum flange, relative to the centre line of the drum. With all type of drums, the rope is subject to a fleet angle which impacts on
