One end of the outer cross-riser to pivotally connected to the base frame, and the opposite end of the outer cross-riser is rotatably and translatably connected to the intermediate frame via a cam and cam follower arrangement in which the cam follower rides on a wear plate. One end of the inner cross-riser is pivotally connected to the intermediate frame, and the opposite end of the inner cross-riser is both rotatably and translatably connected to the base frame via a cam and cam follower arrangement in which the follower rolls against a lower wear plate. A pivotable Trendelenburg linkage is carried on the end of the inner cross-riser connected to the intermediate frame, and a pivotable reverse Trendelenburg linkage is carried on the end of the outer cross-riser rotatably and translatably connected to the intermediate frame. Dual acting hydraulic cylinders power the raising and lowering of the intermediate frame by effecting a scissor movement between the inner cross-riser a…
