Hoist

Hoist

Purpose:
Typical function of Cargo Hoist is to transfer ULD’s between various levels as an intererfloor connection between functional group/zone.
Usually the cargo hoists are used in multiple level cargo handling terminal for pure ULD handling systems with high throughtput.

Description

Purpose:
Typical function of Cargo Hoist is to transfer ULD’s between various levels as an intererfloor connection between functional group/zone.
Usually the cargo hoists are used in multiple level cargo handling terminal for pure ULD handling systems with high throughtput.
Cargo hoist are supposed to work fully automatically, partly because of their high speed in operation.
Several roller deck levels can be reached depending on the building terminal or steel strcture design.
Operation:
The hoist supplies the different floors via a lifting carriage. The lifting carriage is guided in rails and is motor- driven via lifting cables which are fastened by rope hangers to square bars and guided over pulleys to a cable drum.
A catching device is mounted on the lifting carriage and is triggered by a speed governor when the lowering speed is exceeded, thus preventing the lifting carriage crashing down (e.g. by cable breakage). The hoist unit lifts and lowers the lifting carriage so that the roller deck can convey the ULD onto the floor. After driving to the relevant floor, it deposits the ULD there in the same orientation as the ULD entered.
The hoists operate fully automatically during normal operation.
