Abstract: A telescopic outrigger is swivel mounted and disposed so that it can be moved in the longitudinal direction in an jib trough. When the telescopic jib is in its horizontal or slightly inclined operating position, it is situated in the jib trough. In order to achieve a steep operating position, it is moved lengthwise in the jib trough in the direction of the jib tip, and is raised up about a pivot.

Abstract: A lifting apparatus arranged on the side of a vehicle frame for vehicles such as various model size forklifts ensures exact vertical movement of the load. The lifting apparatus includes a rocker having inner and outer rockers connected to each other by a common lower rocker bearing and bearing bolt to resist torsion. The outer rocker is directly and operatively connected to a lifting cylinder supported in the vehicle frame. The outer rocker is also operatively connected through a multi-sectional kinematic drive to a rack-and-pinion or drive shaft drive arranged near and operatively connected to the lifting cylinder. An inclination cylinder is operatively connected to pressure bars and is arranged near the lower rocker bearing. The inner and outer rockers are also supported on the front side of a box girder which connects two side portions of the vehicle frame to resist twisting. Visual range is improved and the total mass reduced due to favorable positioning of the center of gravity.

Abstract: A bucket wheel bearing assembly adapted to be attached to a bucket wheel support structure for rotationally supporting bucket wheel shaft to the support structure comprises bucket wheel bearing means to be disposed on the bucket wheel shaft, a bearing box situated outside the bucket wheel bearing means and having a central projection with slanted side faces at the entire outer surface thereof and two side walls, the slanted side faces extending radially outwardly toward the central projection from the both side walls, locking means to be disposed alongside of the central projection of the bearing box, and a plurality of fastening means for connecting the locking means around the bearing box, some of the fastening means connecting the locking means and the bearing box to the support structure.
