Abstract
A push roll assembly mounted to a material receiving apparatus, such as a paver or other material receiving machine, includes a resilient link which allows energy transferred during contact of a supply truck with the push rolls to be gradually transferred to the material receiving machine, to thereby smoothen the impact between such truck and the machine.
Claims19
A device for cushioning a contact between a travelling paving machine equipped with a hopper for receiving paving material and a truck carrying paving material to be deposited in the hopper, the truck being equipped with a tire, the device comprising:
- A. contacting means, connected to the paving machine, for contacting the truck and for applying to the truck a force tending to move the truck in a direction in which the paving machine is travelling, the contacting means movable between an extended position for initially containing the truck and a retracted position;
- B. cushioning means, connected to the contacting means and to the paving machine, for cushioning the force applied to the truck and the force applied to the paving machine by the contact between the contacting means and the truck;
- C. latch means, connected to one of the paving machine and the contacting means, for latching the contacting means in the retracted position, the latch means having a latched state and an unlatched state;
- and
- D. restoring means, connected to the contacting means and to the paving machine, for restoring the contacting means to the extended position.
