MATERIAL LOADING TRAILER APPARATUS

摘要

The loading apparatus of this invention is capable of handling heavy loads such as large round bales of hay weighing fifteen hundred pounds or more without requiring the use of hydraulic, electrical or any other auxiliary power source. The apparatus includes a ground wheel supported portable frame having a tongue structure connectible to a tractor and with the portable frame by a lost motion means. A load carrying frame is movably supported on the portable frame for movement between a lowered bale loading position and an elevated bale transport position in response to the lost motion of the tongue structure relative to the portable frame. With the load carrying frame in its loading position and the tractor advance, a pair of lift members on the load carrying frame are moved into engagement with the ground wheels for movement forwardly and upwardly thereon to lift the load carrying frame to its transport position. Means are provided for disengaging the lift members from the ground wheels as the load carrying frame approaches its transport position wherein it is automatically and releasably locked against movement to the loading position.
