A lifter device includes: a pole; a lifting member configured to be guided by the pole; a motor configured to generate power used for ascending and descending of the lifting member; a transmission mechanism configured to transmit the power of the motor to the lifting member; and a preventing member configured to prevent the descending of the lifting member when the power is not transmitted.

A lift device (10) of a tugger train trailer(1) is disclosed for raising and lowering a cargo carried in the tugger train trailer (1). The lift device (10) has a lifting shaft (21) driven by a drive motor (20) and mounted so that it can rotate around an axis of rotation (D), and to which at least one lift linkage (25a; 25b; 25c; 25d) that raises and lowers the cargo is coupled in an articulated manner at some distance from the axis of rotation (D) of the lifting shaft (21).

-- A container retrieval apparatus includes: a warehouse arranged inside a body and provided with a goods inlet; an extendable device having extendable arms arranged on two opposite sides of the goods inlet, each extendable arm having at least three arms capable of sliding relatively and extending in a first direction corresponding to a goods inlet and outlet direction of the warehouse, first arm sections of the arms are slidably connected to the body, and tail ends of tail arm sections that are away from the body are provided with shifting finger structures; a driving device including a driving assembly for driving the first arm sections to slide relative to the body, and a linkage mechanism for driving linkage between adj acent arms in each extendable arm; and a control device which controls the shifting finger structure to rotate to a position where a container to be carried can be shifted. --

Disclosed is a payload transportation device for transporting a payload, which has a low height and in which driving wheels are configured to come into constant contact with a ground surface even when the ground surface is uneven. The payload transportation device includes a loading plate above which a payload is loaded, a lift-driving portion configured to generate a driving force to vertically lift the loading plate, a first assembly configured to support a bottom of one side of the loading plate and in which some components included in the lift-driving portion are provided, a second assembly configured to support a bottom of the other side of the loading plate and in which other components included in the lift-driving portion are provided, hinge portions configured to connect the first assembly to the second assembly in a hinge structure, at least a pair of driving wheels coupled to both sides of a bottom of any one of the first assembly and the second assembly, and a driving unit configured to rotate the driving wheels.

A mounting bar assembly mounted to a materials handling vehicle includes a mounting bar extending from a body portion of the materials handling vehicle, a housing mounted to the mounting bar and supporting at least one electronic device, and cabling that extends to the housing through a hollow interior portion defined within the mounting bar. The mounting bar assembly further includes cabling for providing communication between the at least one electronic device and control structure of the vehicle. The housing is mounted to the mounting bar such that the housing can be situated in a plurality of positions along at least a portion of the length of the mounting bar while the cabling is maintained within the hollow interior portion.

A hose header for a lift truck mast is constructed to inhibit wear of hydraulic hoses.

A system for parasitic power generation and control of a load-handler configured to be coupled to a lift truck, with a parasitic energy convertor mounted on the load-handler and coupled via a hydraulic feed line to a hydraulic pump on the lift truck. The parasitic energy convertor configured to generate electrical power for components of the load-handler, including a load-side control transceiver. The load-side control transceiver is configured for controlling control valves based on commands received wirelessly from a truck-side control transceiver. The load-side control transceiver configured for monitoring and control of the load-handler including event logging and notification of maintenance needed.

An adjustable load handler configured to be mounted on lift trucks with different standard type carriages. The handler comprising a frame assembly, a top hook assembly with a securing mechanism for securing the top hook assembly to the frame assembly in a plurality of positions A center manifold is coupled to the underside of the side shift actuator, with hydraulic connections directly into the side shift actuator. Hydraulic lines coupled to the center manifold and to one or more hydraulic components of the loader have sufficient slack so the top hook assembly can be moved between positions without disconnecting any of these hydraulic lines.
