Reach stacker and container spreader

Abstract

The invention discloses a container spreader, which comprises an opening and closing device for controlling the door of a container to be opened or closed. The opening and closing device is provided with a rotating arm and a driving device for driving the rotating arm to rotate. When the container is hoisted, the rotating arm is driven by the driving device to a position for pushing against the door of the container to be in a closed state; when the container is discharged, the rotating arm is driven by the driving device to rotate so as to be convenient for opening the door of the container. According to the container spreader disclosed by the invention, as the rotating arm which is driven by the driving device to rotate is arranged, the door of the container can be ensured to be in the closed state all the time in the hoisting process because the rotating arm pushes against the door of the container, thereby, the zero leakage of cargoes when the container is hoisted is simply and conveniently realized without other auxiliary tools. Moreover, when the container is discharged, the rotating arm is driven by the driving device to other positions, and thus, the limitation on the rotation of the door of the container can be removed, and the door of the container is opened so as to facilitate discharging, and the operation is simpler. The invention also discloses a reach stacker.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a front loader and a container spreader. Background technique [0002] The reach stacker is a kind of construction machinery mainly used for lifting containers, usually used for container stacking and horizontal transportation of containers in docks and stacking plants. Reach hanger is mainly composed of chassis, telescopic boom, spreader and other parts. The spreader is generally equipped with a rotating and telescopic mechanism, that is, the reach hanger can be telescopic and rotated left and right, so as to flexibly lift containers. [0003] When the front stacker needs to lift the container to a predetermined position and pour out the goods, the container needs to be lifted to a certain height. At this height, the operator cannot open the door lock of the container door (the door is located on the side of the container). Therefore, it is necessary to open the d...

AI Technical Summary

Problems solved by technology

This method has the following technical problems: during the lifting process, the container door is in a free state not restricted by the door lock, and the goods in the container are easy to squeeze open the door and leak out, thereby causing unnecessary waste and affecting the loading and unloading efficiency. may also cause environmental pollution

With this kind of lifting method, since the container is in a tilted state during the lifting process after the door lock is opened, the cargo is not easy to leak out. However, the spreader needs to lift the tilted container, that is, the spreader needs to be in the unbalanced load state for a long time, which affects the safety of the equipment. service life, moreover, setting up the auxiliary platform also increases labor cost and labor intensity
