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.

A load-handling clamp mountable on a lift truck has one or more hydraulic clamping cylinders of the type having two or more sequentially extensible stages capable of applying either load-weight-responsive variable hydraulic load-clamping force or, alternatively, load-size-responsive variable hydraulic load-clamping force, without risking the clamp's dropping of a clamped load. The length of the hydraulic clamping cylinder(s) may in some applications extend generally forwardly from a supporting lift truck, and in other applications extend generally laterally from a supporting lift truck.

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.

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.

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 material handling clamp having a proportional relief valve delivering pressurized fluid to clamp arms that grasp a load, and having a controller configured to receive load geometry data and variably control the proportional relief valve to provide a target clamp force.

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.

A hydraulic control circuit operable to selectively hydraulically link first and second hydraulic actuators and to bypass that hydraulic link.

Hydraulic valve circuitry adapted for hydraulic connection to a lift truck having a mast and at least one lift cylinder for alternately raising and lowering the mast. The hydraulic assembly is also adapted for hydraulic connection to an attachment to the lift truck, the attachment having opposed clamps actuated by respective clamp cylinders. The hydraulic assembly preferably comprises a valve circuit capable of causing the at least one lift cylinder to be an accumulator.

A spool-less system for deployment, recovery and manipulation of a traversable road covering track. The system includes an arcuate guide member detachably coupled to a retaining member; the guide member and retaining member defining a volume for receiving a roll of traversable road covering; the guide member arranged to contact the roll along a first arcuate range and the retaining member configured to contact the roll along a second arcuate range; and wherein the guide member and retaining member are detachably coupleable having, a first position in which, the guide member and retaining member are separated at a first diameter whereby the roll of traversable road covering may be deployed or recovered when the host machine is in motion, and a second position in which, the guide member and retaining member are separated at a second diameter in which the roll of traversable road covering is retained.
