A large manipulator for concrete pumps a distributor boom that includes an articulated boom mounted on the boom pedestal and formed by multiple articulating boom arms with multiple joints for pivoting the boom arms with respect to the boom pedestal or an adjacent boom arm. A control device controls the movement of the articulated boom with the aid of drive unit actuating elements associated with the articulated joints. A device determines the vertical speed v.sub.∥ and/or horizontal speed v⊥ of a location on at least one boom arm in a coordinate system referenced to the frame. A device is also provided for determining the articulating angles of the joints. The control device controls the movement of the articulated boom by providing positioning control variables SD.sub.i for the actuating elements of the drive units, which positioning control variables depend on the determined vertical speed v.sub.∥ and/or horizontal speed v⊥ of the boom arm location, and on the determined articulating angles ε.sub.i of the joints, and/or on an angle of rotation ε.sub.18 of the boom pedestal about a vertical axis, and on control signals S for adjusting the distributor boom generated by a controller that can be operated by a boom operator.

A transportation apparatus (30), includes a bracket (31), a telescopic apparatus (32) and a manipulator (33), where the bracket is mounted to a storage shelf (20), the telescopic apparatus is mounted to the bracket, the manipulator is mounted to the telescopic apparatus, and the telescopic apparatus is used for driving the manipulator to move along a horizontal first reference line (S5) or a horizontal second reference line (S6). The manipulator is driven to move on the first reference line and second reference line that are disposed orthogonally, and thereby the manipulator is able to load or unload goods at any position on the first reference line or second reference line, so as to avoid time being wasted on adjusting an angle of a transportation robot (100). The transportation apparatus has a high transportation efficiency.

A pallet sled includes a lower frame and an upper frame. A plurality of pivot arms pivotably connect the upper frame to the lower frame. The upper frame is movable between a lowered position and raised position. The upper frame is spaced further from the lower frame in the raised position than in the lowered position. The upper frame is rotated slightly relative to the lower frame when moved from the lowered position to the raised position. In the example embodiment, the upper frame is rotated approximately 1.5 degrees to approximately 2.0 degrees toward the upright handle of the pallet sled.

The invention relates to a lifting system for lifting a load, such as a vehicle, and a method for lifting a load. The lifting system includes: one or more lifting devices; a group controller arranged to operate the lifting devices; and a user interface unit including a transmitter and/or receiver configured for communication with the group controller, a processor, a display device, and input means configuring the user interface unit to receive user input. The user interface unit is adapted to communicate command signals to the group controller on basis of the user input and adapted to receive and display information obtained from the group controller. The lifting system includes a network interface unit including a network transmitter and/or network receiver configured for communication to an external network.

This invention relates to a fork carriage for a truck mounted forklift, the fork carriage comprising an upright rear section for mounting onto the lifting assembly of the forklift, an upright forward section, shorter than the upright rear section, for reception of tines, and a pantograph linkage connecting the upright rear section and upright forward sections together. The pantograph linkage comprises a first and second linkage arm however the second linkage arm is shorter than the first linkage arm and does not extend all the way forward to the upright forward section. Instead, there is provided a third linkage arm with a hinge joint along its length, the third linkage arm being connected at various positions along its length to each of the first linkage arm, the second linkage arm and the upright forward section. In this way, the pantograph linkage can achieve the same reach with a lower upright forward section and access to top far side loads is facilitated.
