An outrigger assembly for support of a mobile crane or excavator upon the ground, includes a plurality of outriggers mounted to a vehicle frame and having free ends, wherein each of the outriggers has a ground-engaging pad connected to the free ends for vertical movement in relation to the ground. Each of the outriggers has at least one outrigger arm unit movable with respect to the vehicle frame between an idle position suitable for travel between sites, and an operative position suitable for support on the ground, wherein the outrigger arm unit includes an outrigger arm made of a hollow profile which has a lower part of U-shaped configuration and an upper part of calotte-shaped configuration.

A locking unit for a telescopic system of a hydraulically actuated telescopic jib of a crane, having a jib box frame and a plurality of telescopic sections which are guided inside one another and can be moved out of a starting position into in each case at least one extended position is provided with a drive for moving at least one driver bolt of a locking unit into and out of a section receptive driver bolt opening, and for moving a coupling device for displacement of at least one locking bolt into and out of a locking bolt receptive opening, the drive being arranged fixedly on the box frame of the jib, there being a mechanical drive connection between the drive and the locking unit.

Locking unit for a telescopic jib of a crane and telescopic jib

A crane includes a telescopic jib having telescopic jib sections and a base jib. The telescopic sections are arranged so that they can be axially moved into and out of the base jib individually. Locking pins are used hold the telescopic sections in place once they are in the required position. A hydraulic piston-cylinder unit arranged in the telescopic jib can push or pull individual jib sections when the respective locking bolts are removed. The movable portion of the piston-cylinder unit has two securing and locking units located at opposing ends of the movable portion. To move the jib section, one of the securing and locking units is connected to the jib section to be moved and the movement of the movable portions pushed or pulls the telescopic section. Once the jib section is moved to a desired position, the locking pin is reinserted to hold the position of the jib section. Since there are two securing and locking units, the piston-cylinder unit is approximately half the length of the telescopic section.
