Twin lifting device with positionable mounts for handling containers

摘要

The device has mountings (16,17) in the middle of the adjustable length lifting beam (5) which can be guided to vertically and horizontally coordinated positions along non-straight line paths. The mountings are moved by swivelling levers, sliding cylinders and guides. The mountings can be at least partially adjusted in vertical position against a force generated from a mechanical or gas spring, hydraulic cylinder or similar. The mountings are correctly positioned with, and are fixed by swivel pins to, the corners of the containers. The middle mountings can be swivelled away when handling a single container.
