A pivot frame assembly pivotably mountable in a fork-carriage apparatus includes: (a) a lower cross member; (b) an upper cross member; (c) a pair of laterally spaced apart first and second side members connecting the upper and lower cross members; (d) a fork assembly mounting shaft supported by the first and second side members; and (e) a reinforced central support member laterally intermediate the first and second side members and connecting the upper and lower cross members.

Systems and methods for providing a rotatable boom attachment that is rotatable about at least two different axes with respect to an attached boom are described. A system embodiment includes, but is not limited to, a body portion configured to couple to a distal end of a boom, the body portion coupled with a rotational actuator configured to rotate the body portion about a first rotational axis with respect to the boom; a connecting arm rotatably coupled to the body portion; and a motor configured to drive the connecting arm about a second rotational axis having an orientation differing from the first rotational axis, wherein at least one of the body portion or the connecting arm includes a mounting site configured to removably couple to one or more implements.

A fork-carriage apparatus for a lift truck and configured for pulling a load, including: (a) a mounting frame assembly; (b) a side shifter frame assembly slidably mounted to the mounting frame assembly; (c) a pivot frame assembly pivotably mounted to the side shifter frame assembly for translating therewith; (d) a fork assembly mounted to the pivot frame assembly for pivoting therewith; and (e) at least one load-pulling connector mounted to the pivot frame assembly and configured to connect the load to the fork-carriage apparatus for pulling the load.

The present disclosure discloses a hydraulic control system. The hydraulic control system may include a hydraulic module, a PLC control module, a hydraulic valve group control module, a manipulation module, and an action module. The manipulation module is connected with the PLC control module and is configured to input an operation instruction to the PLC control module; the PLC control module is respectively connected to the hydraulic module and the hydraulic valve group control module, and is configured to output a control signal corresponding to the operation instruction to the hydraulic valve group control module, and control the activation of the hydraulic module to provide hydraulic pressure to the hydraulic valve group control module; and the action module is connected with the hydraulic valve group control module, and is configured to perform an action corresponding to the control signal.

To realize a fork lift device capable of contributing to space-saving for an aisle width at a warehouse. A fork lift device according to an embodiment of the present includes: a first fork and a second fork moveable in a lateral direction and a vertical direction with respect to a traveling direction; and an interchanging mechanism configured to interchange vertical positions of the first fork and the second fork.

A pivot frame assembly pivotably mountable in a fork-carriage apparatus includes: (a) a lower cross member; (b) an upper cross member; (c) a pair of laterally spaced apart first and second side members connecting the upper and lower cross members; (d) a fork assembly mounting shaft supported by the first and second side members; and (e) a reinforced central support member laterally intermediate the first and second side members and connecting the upper and lower cross members.

A fork-carriage apparatus for a lift truck includes: (a) a mounting frame assembly mountable to the lift truck for vertical movement; (b) a side shifter frame assembly slidably mounted to the mounting frame assembly; (c) a pivot frame assembly pivotably mounted to the side shifter frame assembly for translating therewith; (d) a fork assembly mounted to the pivot frame assembly for pivoting therewith; and (e) at least one load-pulling connector mounted to the pivot frame assembly and configured to connect a load to the fork-carriage apparatus for pulling the load.

A carriage for a lift truck arranged to provide for both lateral shifting and tilting of attachments such as forklift forks, in which an outer frame of the carriage is supported by a side-shifter cylinder-and-piston assembly incorporated in an inner frame, and in which the outer frame can be tilted with respect to the inner frame, about a laterally-extending central axis of the side-shifter cylinder-and-piston assembly.

Examples of an alignment assembly for loading a shipping container are disclosed. In one example implementation according to aspects of the present disclosure, the alignment assembly includes a base rotatably disposed on a pole and an alignment bracket moveably connected to the base. The alignment bracket may include a main support member connected to an alignment member. The alignment bracket is configured to permit the alignment member to be disposed substantially co-planer with a sidewall of the shipping container.

A side shifter configured for use on a lift truck with an actuator of the side shifter embedded in and almost completely surrounded by the weight bearing components of the side shifter, particularly the fork base top bar and back carriage top bar. This arrangement provides additional protection to the actuator. Embedding the actuator in the weight bearing components of the side shifter also provides for a larger unobstructed view through the middle side shifter.
