Abstract

See full text

A cargo handling vehicle such as a forklift truck having a push-pull unit is improved in responsibility, operation speed and in precise operability by: replacing a conventional hydraulic cylinder for moving a face member 10 back and forth along forks 9 of the vehicle with an electric motor 32. The thus employed motor 32 also eliminates a fear that a cargo 26 is smudged with oil leaking from the hydraulic cylinder and pressurized-oil supply pipes thereof. In cargo loading and discharging operation conducted by the cargo handling vehicle, the face member 10 of the push-pull unit of the vehicle is automatically operated so as to move back and forth along the forks 9 of the vehicle at the substantially same traveling speed as that of the vehicle in a direction counter to a vehicle traveling direction, whereby the sheet pallet B' carrying the cargo 26 is kept substantially stationary during cargo loading and discharging operation or the vehicle.
