  • this device although greatly improving the known push-pull devices, still has certain disadvantages: in particular, the load is nevertheless deported to the front of Forks with a value of 200 to 300 mm, the visibility through the deck is difficult since the rickshaw arm is implanted in this area, and the thrust force is variable as it depends on the angle of opening of the arm.
  • the publication GB 651,215 proposes a handling machine provided with a pusher in the form of a vertical plate disposed at the front of the mast and moved horizontally, parallel to the forks, by two parallel cylinders arranged outside the handling machine , above guide rails in which rollers circulate, for guiding horizontal translation of said pusher.
