Pallet retrieving mechanism for forklift vehicle

摘要

A forklift vehicle has hooks mounted on the forks for preventing removal of a loaded pallet from the forks and a gate for ejecting the contents of the pallet as the forks are withdrawn. The hooks are normally biased out of engagement with the pallet but a cam mechanism moves the hooks into pallet engaging position when the forks are moved to a selected unloading height. The gate is mounted on the rear of the forks and is biased there by two pairs of extensible links. During unloading the forks are moved forwardly and downwardly to bring the gate in front of a pair of stops. The forks are then moved rearwardly, withdrawing the pallet while the gate ejects the pallet contents. The forks are then raised above the stops, allowing the biased links to return the gate to its rear position.
