Appl. No.:

5/545930

Inventors:

International Classification:

B60D 312

US Classification:

214 86A

Abstract:

A compact truck-mounted towing crane is constructed with a boom pivoted near the center thereof. A tow bar secured at the rear end of the boom is positioned below the boom pivot, and a power cylinder is connected to the forward end of the boom for raising a vehicle which is to be towed. The boom pivot is at the rear of a base secured to the frame of the towing vehicle and the power cylinder is secured to the front of the base. The relative positions of the boom and power cylinder are such that the power cylinder arm is retracted during the power stroke to lower the front end of the boom, thereby raising the tow bar and the load thereon. The tow bar together with the portion of the boom to the rear of the main pivot are removable as a unit by simply withdrawing a pivot pin which connects front and rear sections of the boom together in the vicinity of the main pivot. The rear section is movable about this pivot pin between an extended or working position and a storage position wherein the tow bar is positioned above and to the rear of the main pivot.

Abstract:

Repositionable lift apparatus is constructed of a boom pivoted at one end near the upper end of a post. The other end of the boom pivotally supports a platform and a power cylinder is provided to pivot the boom to raise its other end from a loading position to a working position. In the loading position of the boom one end of the platform is a grade so that a vehicle may be rolled thereon. In the working position of the boom a stop means on the platform engages the boom to position the platform in a raised generally horizontal position. A manually operated winch is provided on the boom to load a vehicle on to the platform and a safety means automatically positions itself to block sudden collapse of the power cylinder arm.
