Abstract: A hoist for vehicles such as pickup trucks and sport utility vehicles is described. The hoist engages a standard trailer hitch and when erect allows loading of the trailer. Additionally, when used with a vehicle having a tailgate the hoist does not interfere with the normal operation of the tailgate. The hoist also features structural supports that are deployed to contact the ground thereby reducing the stress on trailer hitch and some structural members of the hoist.

Abstract: A winch spooled with a cable is provided for mounting on the boom of a host vehicle. The winch is surrounded by a frame housing that is capable of withstanding the forces applied by the host vehicle. A braking mechanism is provided for controlling the spooling and unspooling of the cable. The winch is mounted on the boom of a host vehicle by a conventional attachment that is used for other custom tools such as buckets of a backhoe.

Abstract: A load handling assembly that is attachable to the receiver of a receiver hitch assembly of the pickup truck. The load handling assembly includes a winch assembly in connection with a rotatable support structure to allow heavy loads to be lifted to the level of the pickup truck bed and then rotated into position over the pickup truck bed prior to lowering. To accommodate users stationed on the ground or on the bed of the pickup truck, the rotatable support structure is provided with two separate winch mounting brackets so that the winch could be safely mounted to accommodate operation from the desired location.

Abstract: A boom and mast apparatus includes a transverse support member which has a proximal portion and a distal portion. A longitudinal mast assembly is connected to the distal portion of the transverse support member. The longitudinal mast assembly includes a support-member-connected end and a boom-member-connected end. The longitudinal mast assembly also includes a lower segment connected to the transverse support member, an upper segment, and a connector assembly for selectively connecting the upper segment to the lower segment. A first bearing ring is connected transversely to a topmost portion of the lower segment. A second bearing ring is connected transversely to a bottommost portion of the upper segment. The second bearing ring is placed in registration with the first bearing ring when the boom and mast apparatus is assembled. A boom member is connected to the boom-member-connected end of the longitudinal mast assembly. A winch assembly is connected to the upper segment of the longitudinal mast assembly.

Abstract: The present invention is directed to a device for lifting heavy items from machinery in confined areas. The device of the invention can be easily mounted on a particular piece of equipment and allows for the easy removal of the part or item to be repaired or replaced. Because of its relatively small size, the device can be readily used in confined areas.

Abstract: An extendable lifting apparatus for a vehicle. The apparatus includes a support bracket secured to the floor of the vehicle. A tube is mounted to the support bracket perpendicularly to the axis of the vehicle frame. The tube receives a boom which is used to support a cable used to lift heavy objects. The tube is substantially rectangular and has an axial slot extending along the bottom to form an axial opening that allows the cable to be suspended therein when the boom is in the fully retracted position. The slotted wall of the tube also acts as a floor opposite an inner ceiling. A winch is coupled to the boom for successively winding and unwinding the cable. A motor is coupled to the tube for moving the boom from a retracted position wholly within the tube to an advanced position. A second motor is coupled to the winch for controlling the winding and unwinding of the cable. Control of the two motors is provided by a remote control.

Abstract: A boom point construction connects the for and aft mountings of a sheave swivel to the major structural elements of a boom. The boom point includes a framework of elongated members joined together to form a truss. The framework includes assemblies of at least three members joined together at one common point and extending in different directions from the point to define three different planes. Two of the assemblies extend from opposite sides of the front swivel support and another of the assemblies extends from the rear swivel support. A member of the assemblies from the front swivel support is connected to members of the assembly extending from the rear swivel support. The boom point is shown connecting the swivel to a boom having either three or four major longitudinal structural elements.

Abstract: A portable crane for hoisting electric scooters, wheelchairs and the like includes a column assembly, a boom assembly, a base assembly and a winch assembly. The column assembly is removably and pivotally mounted between an opened vehicle trunk lid and a trunk floor. The column assembly includes top and bottom pivot pins which rotatably engage pivot pin receiving holes and about which the boom assembly rotates. The column assembly and boom assembly are collapsible so as to allow the trunk lid to close.

Abstract: A lift mechanism is provided for transferring an outboard motor to and from the body of apickup truck or the like, being primarily usable in moving the motor from a use position on a boat (or from a temporary stored position on a rack or the like) to the interior of the vehicle. The lift comprises a rectangular frame with a boom that can be swung about a vertical axis during motor transfer and that can be folded within the vehicle when the motor is being transported after being lifted into the vehicle. The frame is further slidable fore and aft in the truck body to facilitate motor handling. A releasable lock is provided for locking the frame in forwardly stored position. The provision for sliding of the frame also includes provision for enabling easy removal of the frame when its use is not required.

Abstract: To enable the crane driver of a double link level luffing crane to adapt the height of his cab above the ground to the size of the ship to be loaded or unloaded, the drivers cab is mounted at the end of a separate cab link having a hinge connection with a carriage movable on the strut member of the crane.

Abstract: There is disclosed a hoist adapted to be mounted on a conventional sectional scaffold structure in which the hoist apparatus consists of a boom assembly to be mounted near the top of a scaffold structure and a winch assembly to be mounted near the bottom of such structure. The winch assembly includes a cable drum and a cable, a worm gear drive for the drum and a two-speed pulley drive from the motor to the worm gear. The cable runs upwardly in proximity to a column of the scaffold structure and through a short hollow vertical mast section on top of which is mounted a rotatable boom having a pair of pulleys to guide the cable out of the top of the mast section to the end of the boom and downwardly to receive a load. The mast section supporting the boom may be only about six feet long and is removably attached to a column of the scaffold structure so that the scaffold structure effectively supplies the mast for the boom of the hoist.

Abstract: A foldable hoist assembly has an elongated column with a boom pivotally mounted at its outer end to be moveable from a stored position alongside the column to its operating position. A spindle with radial and thrust bearings in the support column base provides rotary support so that loads suspended from the bottom can be swung over and away from the load bed. The base of the support column is also pivotally mounted on a horizontal support structure affixed to the vehicle chassis, preferably in the position of a bumper below te rear edge of the load bed. With boom stored alongside, the support column is rotated from its upright operating position to be supported horizontally within the support structure leaving the load bed unobstructed.
