A pallet truck adapter having side by side shoes for fitting over pallet supporting tines, in which the shoes are of different heights. This facilitates locating one pallet on the higher shoe, lifting it slightly off of the supporting surface, and then moving to and lifting another pallet on the lower shoe. The adjacent pallets can then be moved together and off loaded at different locations, unloading the pallet on the lower shoe first, and the pallet on the higher shoe thereafter.

Pallet truck adapter

A cart may include a frame, a plurality of wheels carried by the frame, a platform movably carried by the frame, and a lift assembly. The lift assembly may be carried at least in part by the frame and operably associated with the platform to move the platform relative to the frame. The lift assembly may include at least one hydraulic actuator having a piston rod movable under hydraulic pressure to move the platform relative to the frame.

Cart with movable platform

A thermoformer apparatus having a press driving upper and lower platens by respective pairs of servo motors, each pair driving four toggle linkages to stabilize the platen against the forming pressures. Linear bearings are provided on four corner posts for precision guiding of the platen motion.

Thermoforming apparatus with improved press

A wheeled tooling cart for a thermoformer machine enabling quick and easy removal and installation of upper and lower tooling plates from their respective platens. The tooling plates are held on upper framework on the cart, which are removed one at a time with the cart in position adjacent the machine with one and the opposite end successively. The tooling plates are held in position on the cart for reinstallation when the cart is appropriately repositioned with respect to the thermoformer machine. An elevator mechanism allows an upper framework having attachment brackets and rails for holding the tooling plates to be raised and lowered on a wheeled lower framework to move the attachment brackets and rails into proper position for attachment and removal of the tooling plates.

Cart and method for changing tooling in a thermoformer machine

A preheater and method of preheating a thermoplastic sheet prior to entry of the sheet into a differential pressure forming machine which forms an article in the sheet. The preheater includes mechanism for initially threading a sheet in a generally horizontal plane, mechanism for concurrently displacing upstream and downstream portions of the sheet in vertically opposite directions relative to the horizontal plane to dispose a portion of the sheet in an upstanding plane. A heater is provided for heating the upstanding portion of the sheet in the upstanding plane. After the sheet has been repositioned with a portion in the upstanding plane, the heater is laterally moved from an inoperative position to a sheet heating position receiving the portion of the sheet at the sheet heating station. Mechanism is provided for selectively moving the sheet downstream after the sheet has been vertically displaced.
