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.

A forklift linkage system (100) for movement has a levelling carriage assembly (110) movably contained within a channel assembly (120). A main long link pivotally connects to the levelling carriage assembly (110) at a first pivot point (111) and a fork carriage assembly (150) at a second pivot point (151). A short link (140) pivotally connects near a midpoint (131) of the main long link (130) at a third pivot point (121) and at a fixed pivot point (121) relative to the channel (120), near a vertical offset position from the pivot point of the main long link (130) to the levelling carriage assembly (110) at a fourth pivot point (112). A levelling link (160) pivotally connects to the levelling carriage assembly (110) at a fifth pivot point (151) and at the opposite end to a fork carriage assembly (150) at a sixth pivot point, such that the travel path of the second pivot point (151) connecting the main long link (130) to the fork carriage assembly (150) remains substantially perpendicular to the channel (120) when the linkage system (100) is moved between retracted and extended positions. The angle through the second pivot point (151) connects the main long link (130) to the fork carriage assembly (150). The sixth pivot point (152) connects the levelling link (160) to the fork carriage assembly (150) substantially constant in relation to the channel (120) when the linkage system (100) is moved between retracted and extended positions.

An Automated Guided Robot (AGV) system designed for carrying, storing and retrieving inventory items to and from storage shelves. The AGV (100) can move between warehouse shelves and reach to the inside of a shelf without turning. The AGV (100) is equipped with a material handling device (130). The material handling device (130) comprises a lateral device that is configured to move in a lateral direction either to the right side or to the left side. The movement of the lateral device can be either rotational or translational. The material handling device (130) further comprises a retractable device that retracts or extends in a direction perpendicular to the lateral direction. The retractable device allows the material handling device (130) to extend into the storage shelf to fetch or place an inventory item.

A horizontal conveying carriage includes: a carriage body including: a base part; a drive wheel; and a steering wheel; a forklift attached to the carriage body, and configured to pick up a conveyed object and unload the conveyed object; an extending and shrinking mechanism configured to extend and shrink the forklift in a front-and-rear direction; a lifting and lowering mechanism configured to lift and lower the forklift in a vertical direction; a supporting mechanism configured to support the forklift from a lower side; an own position estimation unit configured to estimate an own position of the carriage body; a positional relation recognition unit configured to recognize a positional relation between the own position and the conveyed object; and a control unit configured to control movement of the carriage body and to control an operation of the forklift based on the own position and the positional relation.

A pantograph assembly may include a mast carriage assembly comprising a trunnion cross-member and a trunnion shaft coupled to the trunnion cross-member, and a pantograph mechanism coupled to the trunnion shaft.

The invention relates to a modular sliding fork for a fork-lift truck or pallet truck, a fork-lift truck or pallet truck provided therewith and a method therefor. The modular sliding fork includes a sliding part configured to be adjusted in length direction relative to a fork part of a fork of a fork-lift truck or pallet truck, a drive system for sliding the modular sliding fork relative to the fork part for the purpose of extending and/or shortening the fork; and a locking mechanism for locking the modular sliding fork relative to the fork part at a desired position. The drive system utilizes a movement of the fork-lift truck or pallet truck for the purpose of sliding the modular sliding fork.

Apparatus for installing a solar panel array in parallel rows on panel support structure, as for solar farms, including a lift-and-place vehicle with characterizing features for moving between and along rows of support structure. Such vehicle includes a driven ground-engaging base, a lifting mast extending upwardly and in a fore/aft direction to define a panel-loading space therebeneath, a liftable trolley beam secured to the mast over the panel-loading space and extending laterally between adjacent rows, a traversing trolley movable along the beam, and a panel-placing carrier suspended from the trolley for up/down and lateral movement of carried panels. A panel-pallet vehicle is hitched to the lift-and-place vehicle, extends under the panel-loading space, and has a pallet carrier adjacent to the panel-loading space. Preferred embodiments include telescoping, tilting and angle adjustment of the mast, and the panel-placing carrier has panel supports movable between panel supporting and releasing orientations, and wireless control.
