Abstract: A trailer having a length varied by the extension of beams from an extendable end. The trailer is further defined by having a saw on the extendable end and a crane for holding trees on the other end, which is typically a low end. The trailer also has, at the extendable end, hydraulicly controlled supports for leveling the trailer at the extendable end. The trailer is also defined as being extendable in width as well as the length.

Abstract: A log skidder has a lifting arm which may be raised or lowered by hydraulic pressure. A grapple is carried at the end of the lifting arm for lifting one end of a log to drag it from one area to another. The suspension for the grapple from the arm includes a body pivotally connected to the arm by a first horizontal pivot rod, and the grapple is pivotally connected to the body by a second horizontal pivot rod perpendicular to the first pivot rod. A pair of snubbers respectively encircle the pivot rod. Each snubber includes a ring-shaped hydraulic cylinder having a ring-shaped piston therein. Hydraulic fluid introduced into the cylinder extends the respective pistons to effect snubbing between the body and the arm in between the grapple and the body.

Abstract: A pressure-fluid supply system for use in a hydraulic loader device. Included in the device are a mast mountable on a truck, a platform rotatably mounted on the upper end of the mast, and hydraulic fluid-operated equipment carried on the platform for rotation therewith. The supply system includes a pump anchored on the platform, for supplying hydraulic fluid to the equipment carried thereon, and an engine mounted on the mast. The engine's power output is drivingly coupled to the pump about the platform's axis of rotation, wherein the platform may be rotated endlessly during pump operation.
