Claims

[Scope of utility model registration request]

A gate-shaped support installed upright on the body frame of a container transport vehicle, a spretzer provided for raising and lowering the container in an engaged state within the gate-shaped support via an engagement tool, and the spreader in a suspended state. a front shuttle beam and a rear shuttle beam for raising and lowering along the gate-shaped support, and a pair of front shuttle beams and rear shuttle beams arranged on the left and right so that the front shuttle beam and the rear shuttle beam are raised and lowered by a hoisting device attached to the gate-type support. In the container cargo handling device comprising a front chain and a rear chain, the spreader includes a front movable frame fitted to a fixed frame removably connected to the front shuttle beam and the rear shuttle beam, and a front movable frame slidably fitted in the front and rear directions; It is composed of a rear movable frame and a hydraulic cylinder for moving the front movable frame and the rear movable frame back and forth, and the front chain and rear chain are respectively equipped with a front load cell and a rear load cell, When the output signal of the load cell or rear load cell exceeds a preset value, the front movable frame and rear movable frame are moved in the direction that makes the output signal of the front load cell or rear load cell less than the set value. A cargo handling device for a container, comprising a control valve for supplying and discharging pressure oil to and from a hydraulic cylinder, and a control electric circuit for the control valve.
