ABSTRACT:
A hoist frame comprises a planar member having front and rear opposite ends and top and bottom planar surfaces and a pair of extending members comprising a pair of spaced parallel members extending from the bottom surface at the rear end of the planar member perpendicular to the bottom surface. Mounting means pivotally mounts the planar member of the hoist frame to the chassis frame at the bottom surface at the front end of the planar member in a manner whereby the extending members extend beyond and to an area beneath the chassis frame. A jack is affixed to the planar member of the hoist frame at the bottom surface at the rear end thereof equidistantly from the extending members and extending perpendicularly from the bottom surface for pivotally moving the hoist frame about the mounting means thereof. A pair of boom securing means extend perpendicularly from the top surface of the planar member in the areas of the front and rear end of the planar member for selectively releasably securing a variable length boom at one of the boom securing means or both of the boom securing means.
