  • Patent number: 4442766
    Abstract: A mobile vehicle for crushing scrap metal, especially for flattening car body shells, has a crusher jaw mechanism (11) carried ahead of a generally conventional vehicle body (12). The jaw includes a press plate (55) above a platform (31). The car body shell (90) is loaded on to the platform by advancing the vehicle towards the body shell and driving the platform under the shell, and is then crushed between the press plate and the platform. The jaw mechanism may be carried on an arm or arms (13) which can be raised and lowered. Side plates (32) and a rear gate (80) may be provided on the crusher jaw mechanism to contain light scrap. The jaws may be tiltable, and may be provided with front fork tines (71) to act as an entry ramp and for manipulating the body shells before and after flattening.
