Abstract: Method for loading and unloading long-distance transportation means (1, 2) and for temporarily storing a standardized cargo (18) in an intermediate storage facility (3) includes a rail-guided hoist (5) with gripper (8). The cargo is lifted from a long-distance transportation means (1) and transferred to a transfer zone (4), lowered and set down. The cargo (18) is then transferred to an intermediate storage facility (3) and stored therein, then removed, transferred to a predetermined location in the transfer zone (4), and lowered and deposited onto a rail-guided long-distance transportation means (2) by the hoist (5).

Abstract: A shock absorption device for an idler wheel of a tracked vehicle is provided between an outer mounting element fixed to a chassis and an inner mounting element operatively connected with the idler wheel and includes a spring mechanical unit suspended on the fixed element and a hydraulic unit supported on the lower mounting element and operatively connected with a free end of the spring unit.

Abstract: The rotatably mountable track chain roller has two molded axle journal stubs which each engage rotatably in an end cap formed as a radial and axial bearing. Further expecially the track chain roller is provided with lubricant material for its bearings which has a lubricant action on them. An easy and economical manufacture for the track chain roller results when at least one spacer suitable for providing a set value of axial play in the axial direction of the track chain roller is clamped between the track chain roller and one of the end caps without play. The spacer is made of a soft grindable lubricant-resistant material which does not influence the lubricant action and which is grindable against the track chain roller, the axial journal and the end cap. The spacer can be ring shaped and have a plurality of approximately equal width spacing maintaining regions distributed approximately equally circumferentially around the ring and connected by straps of a narrower width.
