A lifting and depositing device for a large container has connecting longerons which are approximately the height of the container and are attached to the corner fittings of the large container to be raised and lowered. The connecting longerons are arranged at the corners of the large containers and, at the bottom ends at some distance to the side, they support at least one more connecting longeron for an overhang beam of a rack and pinion jack. The rack and pinion jack can be raised and lowered along upright, at the bottom ends of which are arranged pairs of wheels. In order to be able to adjust the pairs of wheels in a simple manner to different track gauges (narrow and wide), the overhang beam can be attached either to the connecting longeron which is approximately the height of the container or to the additional connecting longeron.

Device for lifting and depositing transportable large containers, e.g.

The lifting and depositing device for a large container has four rack and pinion jacks attached to its corners at a low point by overhang beams. The racks are fastened to uprights, along which the rack and pinion jacks can be raised and lowered by suitable operation. In order to move the large containers with the lifting and depositing device, the bottom ends of the uprights are connected by wheel supports with wheels. The wheels are mounted on a wheel swiveling mechanism which has a support surface for the bottom end of the uprights. The wheel swiveling mechanism is rotatable relative to the uprights for controllability of the device. Each support surface for an upright is provided on a rocker mounted on the wheel swiveling mechanism for rotation about a substantially horizontal axis. The support surface is arranged lower in relation to the axis of the wheels so that the wheel swiveling mechanism can be moved when a large container is placed on the ground to the side beneath the rack and pinion jack to position the bottom end of the adjacent upright on the support surface to support and couple them.

Lifting and depositing device for transportable larger containers, e.g.

For the handling of portable large containers, lifting and depositing devices are used, which have rack and pinion jacks to be attached to the corners of the containers by brackets. There rack and pinion jacks have tubular winch shanks which are approximately the height of the containers, into which are guided tubular uprights with the racks. Because of tolerance variations, the danger here arises of an impaired guidance of the uprights with the result of a poor operation of the gearing. To avoid this difficulty, a guide tube is connected with the bottom end of each tubular winch shank. Guide surfaces in the guide tube can be produced with great precision and at low cost. The housing of the winch gearing is configured integral with the guide tube. Thus, a small amount of side play can be left between the upright and winch shank without adversely affecting the rack and pinion gearing operation.
