  • Patent number: 5782176
    Abstract: A material press includes a base portion defining a generally horizontal bed upon which a vehicle (or other material) to be crushed may be placed. Material placed on the bed is crushed by a lid portion which is slidably movable relative to the base along a pair of vertical guide mechanisms by a pair of hydraulic cylinders. Each vertical guide mechanism includes two guide posts. Guide sleeves which slide along the posts are pivotally connected to the four corners of the lid by pivot linkages. The casings of the hydraulic cylinders are movable between a raised position for performing crushing operations and a lowered position to reduce the overall height of the crusher during transportation between job sites. A locking mechanism is provided for quickly locking and unlocking the cylinder casings in their raised position. The base of the material press may be form of a semi-trailer to permit the press to readily be moved between job sites.

  • Patent number: 5112183
    Abstract: A side-loading all-terrain fork lift vehicle for handling heavy loads which are long relative to their width, e.g., junked cars, in a storage facility having multi-level racks separated by narrow aisles and with restricted vertical clearance between levels. The vehicle body has an elongated load-carrying frame section which includes a longitudinal torsion beam at one side, two transverse torsion beams at its front and rear ends, two transverse medial beams defining a guideway for the mast-carrying trolley, and cross-brace beams between the torsion beams and the medial beams. The front and rear wheel axles are supported by respective rocker frames pivotally mounted on the associated transverse torsion beams and adapted to be angularly moved up and down by respective hydraulic piston and cylinder units which enable the frame section to be lowered so as to rest on the ground during on-loading and off-loading for maximum stability of the vehicle.
