摘要： The invention is a unitary cantilever liftgate that attaches to the vehicle body instead of the vehicle chassis. The liftgate may be fully assembled and tested prior to installation on the vehicle body. This greatly reduces installation time while improving performance and reliability. Various features such as steps, bumpers and brackets are integrated into the liftgate. Further, the liftgate is preferably configured so that multiple units can be stacked together for shipping and ease of unloading and loading. The stackability of the liftgates simplifies storing as well, by removing the necessity of storing several components separately.

摘要： An improved system is provided for hoisting loads from ground level to a truck platform, which has particular advantages on flat bed trucks. Ramps are provided for rolling loaded dollies off a curbing or from the ground onto a lower lift platform position where they are raised by a motor powered hoisting mechanism with the lift platform up to the truck platform. The system is stowed and carried entirely beneath the truck platform so that it does not interfere with its utility or introduce any members above the truck platform. A pivotable lift platform permits storage in a vertically oriented position to prevent the system from extending significantly back of the truck platform. A low powered d-c reversible motor rotates vertical drive screws mating with a drive yoke attached to opposite ends of the lift platform. The lift platform is spring biassed upwardly to aid in lifting loads upwardly to the truck platform with a small motor. A bumper assembly is carried by the system for mounting, license, trailer hitch, lights, etc. Also loading tray extensions are strapped in the lift platform for optional use. The bottom of the lift platform assembly is above ground level and cooperates with a self contained loading ramp which extends to ground or curb level from sides or rear of the lift platform permitting loaded wheeled dollies to be rolled on and lifted to the truck platform.

摘要： A prime mover and box car combination for loading and unloading cargo in which the prime mover and box car are provided with aligned support rails. A cargo handling mechanism is slidably mounted on the support rails for movement between an extended operating position on the prime mover and a cargo handling position on the box car. The cargo handling mechanism is further movable on the prime mover between its extended operating position and a normal retracted storage position.

摘要： An agricultural vehicle designed to be towed behind a farm tractor for lifting and transporting large cylindrical bales of hay. An inverting fork loader is provided for picking up a bale from the ground and depositing it at the front of the vehicle, which has endless conveyor means for transporting the bales rearwardly. The loader and conveyor are both actuable hydraulically. The vehicle has a tongue or draw bar which may be displaced laterally in either of two directions to cause the vehicle to follow the tractor in an offset fashion. One embodiment of the invention has two conveyors, and the loader may be displaced laterally to deposit a bale on either conveyor. Lateral displacement of the loader is reversely coordinated with lateral displacement of the tongue in this embodiment of the invention.BACKGROUND OF THE INVENTIONThis invention relates to the field of agricultural machinery, and particularly to apparatus for facilitating the handling of hay in the form of large cylindrical bales about 5 feet in diameter and 4 feet long, as produced by newer hay harvesting machinery. The baling operation is considerably more efficient, tying and so forth being performed once instead of say 25 times for the same weight of hay, and subsequent handling involves one twenty-fifth as many units, but the cylindrical bales weigh about 1500 pounds apiece, are left lying on their sides on the ground by the baler, and do not lend themselves readily to transportation or handling by heretofore conventional means.SUMMARY OF THE INVENTIONMy invention comprises a vehicle, adapted for towing behind a conventional farm tractor, by means of which the tractor operator can load and transport a plurality of these heavy bales without leaving the tractor, and without the help of other workmen. In one embodiment of the invention the vehicle has a central partition and transports up to ten of the bales in two rows of five bales each carried coaxially. The bed of the vehicle has two longitudinal conveyors actuable to transport rearwardly material resting on them: these conveyors are actuated hydraulically. At the front of the vehicle a loader in the form of an inverting fork lift can be positioned to raise a bale from the ground and deposit it on a selected conveyor at the front end of the vehicle: the conveyor then moves the bale rearward by a bale length. The lift is also actuated hydraulically. The tow bar or tongue connecting the vehicle with the tractor is arranged to be offset, and the loader operation is coordinated with the direction of the vehicle offset. A simplified embodiment of the invention provides a narrower vehicle which can receive 5 bales coaxially along its length, and in which the position of the loader is fixed although the tongue is still displaceable to either side.A principal object of the invention is thus to provide a new and improved agricultural vehicle. Another object is to provide such a vehicle which lifts bales from the ground and deposits them at the front of a conveyor which moves them rearward, all at the control of a single operator. Another object is to provide such a vehicle which will travel offset from the towing vehicle on either side thereof, so that the tractor moves beside the bale to be loaded while the loader engages it. Another object is to provide such a vehicle with a plurality of conveyors on which the loader can selectively deposit the bales. A more specific object is to provide such a vehicle in which displacement of a tongue in one direction to cause offset following by the vehicle automatically displaces the loader in the opposite direction.Various other objects, advantages, and features of novelty which characterize my invention are pointed out with particularity in the claims annexed hereto and forming a part hereof. However for a better understanding of the invention, its advantages, and object attained by its use, reference should be had to the drawing which forms a further part hereof, and to the accompanying descriptive matter, in which there are illustrated and described certain preferred embodiments of the invention.
