  • Flap for cement truck back
    Patent number: 5605398
    Abstract: A rigid cover attached to the chute of a cement truck can prevent the accidental discharge of cement residue from the chute of the cement truck while the truck is moving. The use of a rigid cover prevents the bending of the cover under the weight of the cement residue. The rigid cover can be attached to an over-chute portion of the chute such that when the over-chute rests upon the main chute, the rigid cover can be positioned to prevent the accidental discharge of cement from the chute or can be flopped on top of the over-chute. The rigid cover is designed to hold back a substantial amount of cement residue.
