A counterbalanced vertical track assembly which may be configured with three types of pulley support assemblies are herein disclosed. The first type of pulley support assembly has a pair of opposed pulley modules having an elongate structural element interposed the two pulley modules which are attached to end plates at both ends of the elongate structural element. The second type of pulley support assembly has a pair of opposed pulley modules which include male end connectors for demountable engagement of the pulley modules with another module of the system with female ends. The third type of pulley support assembly has a pair of opposed pulley modules wherein the modules' pulley brackets are repositionable to varying angular orientations by alternating screw mount positions selected on mount components at opposite ends of an elongate structural element.

A lifter device includes a pole, a lifting member guided by the pole, a motor that generates power used for ascending and descending of the lifting member, a controller that controls the motor, a case that is fixed to at least a portion of the pole and accommodates the motor and the controller, a transmission mechanism that transmits the power of the motor to the lifting member, and a battery mounting portion that is provided on the case and to which a battery pack is mouted to supply power to the motor.

A modular fork assembly for a pallet truck includes a discrete elongate body, a discrete load wheel module, and a discrete fork tip that may be detachably connected by the same or different types of interlocking mechanisms that are adapted to inhibit sheer forces. The load wheel module includes a frame and a load wheel assembly that includes a load wheel that is operatively connected to the frame.

A cargo container crane includes a body, having a bottom and top, the body including at least one drive wheel and a turning wheel at the bottom, and a horizontal cantilever at the top, the cantilever and the top of the body including a turning device, a drive motor that drives the at least one drive wheel, a lift motor, a lifting rope, a lifting rope drive device, wherein the lifting rope runs through the turning device, with one end of the lifting rope connected to a hook and the other end of the lifting rope connected to the lifting rope drive device, and a control handle, having a first button that causes forward and backward movement of the cargo container crane, and a second button that causes raising and lowering of the hook.

A device for receiving, transporting and storing pieces of furniture includes a movable support rack and a lifting apparatus fastened to the movable support rack, wherein it is possible to lift a first piece of furniture using the lifting apparatus such that a second piece of furniture can be arranged below the first piece of furniture that has been lifted by the lifting apparatus. The movable support rack includes a locking apparatus for locking the second piece of furniture on or in the movable support rack. The support rack includes a base frame that is open at a front side such that the device can receive the pieces of furniture at the front side of the base frame.

A hand truck for moving an irregularly shaped object includes a rack alternately positionable between first and second use positions. In the first use position two support arms extend forwardly from the frame and in the second use position a substantially planar platform extends forwardly from the frame. The rack is adjustably positionable along the length of the frame. In embodiments, the support arms are positionable to vary the width therebetween. In other embodiments, a pivoting mechanism allows the rack to be readily positioned between the first and second use positions.
