A lock valve including a poppet valve element which is disposed within a spring chamber, a spring which biases the poppet valve element leftward, and a valve seat which comes into contact with the poppet valve element is disposed in a cavity formed in a valve body to mount a relief valve therein and is positioned further inward than the sleeve of the relief valve. The outer peripheral portion of the poppet valve element has hole portions formed therein at regular intervals. The outer peripheral portion of the valve seat, too, has hole portions formed therein at regular intervals. The valve portion of a solenoid valve is disposed between a passage which is in communication with the spring chamber and a passage which is in communication with a second flow passage open to a low-pressure region such as a hydraulic tank.

The invention relates to a delivery system having a delivery goods vehicle for delivering inward goods, and having at least one automated transfer assembly which for transferring the goods in an automated manner from the delivery goods vehicle to a goods store comprises an object detection device. The delivery system moreover has a safety installation for securing a movement range of the transfer assembly when unloading the goods.

The invention relates to an automated transfer assembly for transferring goods, having a frame, having a repositioning installation which for repositioning the frame is disposed on the frame, and having a gripping device which for gripping an item of goods is in connection with the frame. The gripping device comprises a first gripper arm installation for engaging on the item of goods to be gripped, and a second gripper arm installation for engaging on the item of goods to be gripped, said second gripper arm installation being spaced apart from the first gripper arm installation. The transfer assembly furthermore has a control unit for controlling automated gripping of the item of goods to be gripped by means of the gripping device.

The invention relates to a transfer system for transferring an item with a transfer assembly for transferring an item to a transporting carriage in a transfer area and with a transporting carriage for receiving the item from the transfer assembly in the transfer area.

A contact pad is provided having a load-engaging front surface and an oppositely-facing rear surface, preferably comprising a cast metal contact pad having at least one depression adjacent to the rear surface and a tile embedded within the depression such that the tile has an exposed surface, and a wear element on the exposed surface. A method for manufacturing a contact pad having a load-engaging front surface and an oppositely-facing rear surface preferably includes the steps of embedding a mild steel tile within a contact pad casting pattern such that, once embedded, the embedded tile has an exposed weldable surface, casting the contact pad from ductile cast iron and applying a wear element on the weldable surface.

A swing frame roll clamp may include a mounting plate mountable to a lift truck and a pair of opposed clamp arms. The clamp arms may be configured to selectively and alternately grasp and release a cylindrical load, and each opposed clamp arm may be capable of becoming either a short arm or a long arm relative to the other opposed clamp arm.

A universal payload manipulation tool employs a segmented ring captured in a telescoping cradle to perform the positioning functions of both a workstation and a loading adapter. The ring rotates over a range of 360 degrees to perform the position functions of the workstation. With the upper ring segment removed, the telescoping cradle rotates and the lower ring segment rotates and extends from the telescoping cradle over a combined range of rotation to position the payload at a specified angle for unloading to perform the position functions of a loading adapter. This configuration allows the universal tool to access confined spaces while supporting a range of rotation required in many applications for unloading the payload (loading the payload to another platform such as an aircraft). The manipulation tool may also be configured as only a loading adapter.

A clamp device for a mobile lift system and a mobile lift system is provided, where the clamp device has a supporting part and two gripper arms movably connected to the supporting part. An actuating system is arranged on the supporting part, where an actuator is connected to each of the gripper arms. The actuators functions as a main cylinder and a slave cylinder respectively. At least one accumulator is connected to the slave cylinder where the accumulator creates an opposing pressure as a result of the gripper arms' position.

There is provided a device for handling tires having an anchor for attaching to a prime mover and a clamping device rotatably mounted to the anchor that rotates relative to the anchor about a rotation axis. The clamping device has a plurality of engagement members connected by a mechanical linkage and a carrying body with a plurality of guides. The weight distribution of the clamping device is balanced about the rotation axis. Each guide carries one of the engagement members and is oriented to allow the engagement members to move perpendicular to the rotation axis between clamping and release positions. The mechanical linkage includes a rotating actuator and controls movement of the engagement members along the guides. The movement of each engagement member is rotationally symmetric about the rotation axis relative to the movement of the other engagement members. The device has an actuator that actuates the mechanical linkage.
