Abstract
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.

A compacting device located forwardly of a body, especially a closed body of a high capacity semitrailer for receiving by gravity mainly household or industrial waste products as well as any other products of low density, through an opening formed in a forward upper part of such body, comprising two parts moveable one with respect to the other including a compacting shield capable of moving above the bottom of the body and an apron capable of moving above said shield, controls of motions of said shield and said apron, in a first phase move, and of motion of said shield and said apron, in a second phase move, for total ejection of the waste products after transportation, and two other moveable supporting parts including a supporting carriage and a slider supporting said controls, said controls including jacks, one jack supported both on said supporting carriage and said shield, another jack supported on said supporting carriage and said slider, and a further jack supported on said slider and said body.
Claim 3
Dependent Claim
75 words
A device according to claim 1 in which a first lock is provided for connecting said apron with said supporting carriage in said first phase move, and a second lock is provided for connection of said slider with said body in this same first phase move, said first lock connecting moreover said shield and said apron for ejection of waste products from said body after transportation, said slider being then released from said second lock.
Claim 4
Dependent Claim
73 words
A device according to claim 1 in which said shield is conformed so as to present an inclined first slope from the bottom to the front end of said body, and said apron presents a second slope inclined in the same direction as said first slope and capable of being brought into an angular extension of said first slope of said shield, in a given relative position of said shield and said apron.
Claim 5
Dependent Claim
36 words
