    摘要： A unit formed of components which may be shipped in disassembled condition to occupy a minimum of space, yet may be readily assembled and attached to the truck body of a vehicle to provide a mobile unit having a main beam which may be moved from a horizontal transporting position to a substantially vertical or upright position so that said beam may be utilized to raise a load to a substantial height, or said beam may be used as a support whereby a person can stand thereon to perform certain operations requiring considerable height. When the unit is attached to the truck body it has the mobility of the truck and moves with the truck from one place to another and is always ready for instant use.

    摘要： A loading and conveying device for timber logs and the like to be mounted on a motor vehicle. The device comprises an upright mast with a rearwardly directed cantilevered loading beam provided with means for hoisting and carrying the fore end of the load, such as a bundle of timber logs or the like, the rear end of which rests on the ground. The cantilevered beam is at the rear end provided with a transverse yoke member adapted to rest against and partly around the bundle. The winch equipment includes a hoisting strap depending from a point on the cantilevered beam positioned closer to the mast proper. The mast is in its mounting on the tractor body pivotally supported about a horizontal as well as about a vertical axis.

    摘要： An articulated crane is disclosed herein having a turntable base pivotally and rotatably supporting an expandable boom. The boom comprises four beams pivotally connected together substantially at their adjacent ends and adapted to be folded together in a compact storage position and to be extended outwardly from the base so that its free end is cantilevered away from said base. The boom further includes crossover braces pivotally secured between the two innermost beams and the two outermost beams so as to provide a scissorslike extension and retraction of the beams. Hydraulic piston and cylinder assemblages are pivotally interconnected between the base and the first beam of the plurality for effecting initial extension of the boom while a second piston and cylinder assemblage effects refined positioning and extension of the boom via the scissorslike mechanism. Means are operably carried on the extreme free end of the boom for engaging cargo or products intended to be lifted or transferred from one location to another.
