Abstract: A compacting device located forwardly of a body, especially a close body of a high capacity semitrailer which received by gravity, through an opening formed in a forward upper part of the body, mainly household or industrial waste products as well as any other products of low density. The device compresses two parts moveable one with respect to each other which includes a compacting shield capable of moving above the bottom of the body and an apron capable of moving above the shield, with controls to control the motions of the shield and the apron, and two other moveable supporting parts including supporting a carriage and a slider supporting the controls, in the first phase move, and the motion of the shield and the apron, in a second time phase move, for total ejection of the waste products after transportation to a dump site.

Abstract: In a vehicle having a chassis and intended for the transportation and spreading of materials, a combination comprises a chassis extension, a loading and unloading device mounted on the chassis by means of the chassis extension. It includes a hoist having at least one vertical branch with an upper end provided with a hook and a horizontal arm pivotably mounted around a pivoting axle parallel to the ground and transverse to the chassis so as to be able to pivot the hoist under the effect of a jack. A movable container is adjustable in height and includes a cradle provided at the front and at the rear with vertical posts in engaging relationship with sliders each having at least one hooking member to cooperate with said hook. The sliders are connected to a bridge including at least one longitudinal beam and a receptacle supported by the bridge.

Abstract: Truck dump-body operating mechanism comprising a L-shaped member the horizontal branch of which is, on one hand, slidably translatable in side members and, on the other hand, pivoting about a shaft transverse to the chassis of the truck, the vertical branch having a hook cooperating with a fastening member on the forward upper part of the dump-body, a single jack controlling both the sliding motion and the pivoting motion of said horizontal branch, whereby said dump-body may be set down on the ground and subsequently reloaded onto the truck, said truck being a light one having a relatively low useful load, while a locking device allows said dump-body to be tipped up.
