摘要： A lower horizontally elongated base frame is provided and includes depending support wheels. An upright longitudinally extendable boom has its lower end pivotally supported from one end of the base frame centrally intermediate the opposite sides thereof for adjusted angular displacement of the boom relative to the frame about a first horizontal transverse axis extending transversely of the frame and the boom between an upright position and a lower horizontal position closely overlying the frame and with the free end of the boom projecting toward the second end of the frame. A second upper horizontal frame is provided and is pivotally supported from the upper end of the boom for adjusted angular displacement of the second frame relative to the boom about a second horizontal axis generally paralleling the first axis between a first position with the second frame disposed at generally right angles relative to the boom and a second position with the second frame generally paralleling the boom. The second frame includes horizontally aligned, upwardly facing and horizontally spaced apart support portions spring mounted therefrom. The boom comprises an extendible fluid cylinder including one end portion supported from the lower frame and a second upper end portion from which the upper frame is supported. A hydraulic pump is supported from the lower frame and is operatively connected to the boom for selective extension and retraction thereof.

摘要： A convertible boom is supported by an upstanding post and base frame. The boom is provided with appropriately located connectors so that it may be attached to the upper portion of the post to form a hoist or it may be connected proximate the bottom of the post to create a jacking device. In both cases, a portable jack is used to actuate the boom. The end of the boom may be equipped with a rotatable and tiltable cradle having extendable arms. The upstanding post may be provided with a rotatable workpiece mount which includes a plate having a plurality of outwardly projecting pins which extend through slotted connector rods. The rods can be arranged in a variety of positions to facilitate connection to a workpiece.

摘要： A unit in one position on caster wheels for use as a crane for lifting engines while in another position of operation being carried on a second set of wheels only for transport or towing other vehicles. The boom is extendable, pivotal and rotatable and when the unit is used as a towing device it will lift a towed vehicle through a cable arrangement on the opposite side from the boom while the boom is being raised. When the unit is in a crane position a pair of outwardly extending members having casters thereon extend below the boom and stabilize the unit while these same members in the towing position are interconnected by a hitch assembly for attachment to a towing vehicle.
