摘要

A belt-driving roller (19) pulls a draw belt (21). A driving mechanism turns the belt-driving roller and its holding elements (9,17,29). The belt-driving roller, the holding elements and the driving mechanism combine into a subassembly (7) that can be fitted in advance to a modular unit separate from a truck's container. The pre-fitted modular unit can be screwed on one end (5) of the container.
