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.

The present disclosure is directed to device to lift, maneuver, hoist, and install an item such as a flat screen TV, cabinet, mirror, window, on the wall, such installation that would normally require more than one person. The present disclosure relates generally to a device that can lift large bulky heavy items in both vertical and horizontal directions for installing, mounting, and placing on the wall. This is accomplished by smooth and precise horizontal and vertical motion that is controlled by the operator. Manpower has been the common device of choice in many of these instances, and this invention will succeed in the cases that include handling bulky, large, cumbersome items or general items in congested or hard-to-reach places that would typically require more than one person to perform the lifting, installing, mounting, or moving.

The present inventions provides a lifting device 101 comprising a main body 105 being of a generally elongate form, said main body 105 having at one end thereof a transport means 102, 120 to allow said device to translate relative to the ground, a boom portion 103 cooperating with said main body 105 and adapted to support a load at its end, a motive power means 115 to lift or lower said load, said main body 105 being able to be pivoted by a user with respect to a fulcrum 102, 120 formed by either said transport means 102, 120 and a ground location or said transport means 102, 120, around an axis generally parallel to the ground, to transfer or arcuately move a load carried by said boom portion 103, thereby providing a functionally variable horizontal reach 1013 to said device 101.

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.

Four types of telescoping modules are disclosed wherein the first type has a pair of opposed female ends, the second type has a pair of opposed female ends, and the third type has a female end and an opposed male end. The fourth type has two opposed male ends between which a positionable threaded rod and retaining components stably extend the length between the male ends of the telescoping module. Alternatively, the fourth type of telescoping module may have a female end and a male end. Each of the male ends of the second, third, and fourth types of telescoping modular components comprises a cylindrical body with one or more linear set(s) of two or more spaced-apart prongs on the circumferential surface of the cylindrical body. Each of the female ends has a cylindrical receptacle with one or more linear channels and/or prong-retaining slots for receiving therein the cylindrical body.

Disclosed is a low profile rolling support assembly useful for supporting loads above a supporting surface where at least one end of the rolling support assembly is positionable beneath a structure having minimal clearance above the supporting surface. The rolling support assembly includes a load bearing member and a caster assembly containing a wheel where the load bearing member extends laterally away from the caster assembly at substantially the same height or less as the caster assembly.
