| titleOfInvention | Hydraulic propulsion device for dredger |
| abstract | The present invention relates to a hydraulic propulsion device for a dredger, more specifically, the propeller generating the propulsion force is controlled by the hydraulic speed and the rotation speed, and turning the propeller to the left or right with respect to the dredger to turn the dredger's turning direction. It relates to a hydraulic propulsion system for a dredger which can adjust and, if necessary, allow the propeller to lift on and off a dredger. The hydraulic propulsion device of the dredger of the present invention uses a hydraulic motor to propel the dredger by rotating the propeller, and the propulsion and steering structure is concise because the propulsion unit is rotated by turning the propulsion unit from side to side. In addition, since the dredger hydraulic propulsion device of the present invention is capable of raising or lowering the propulsion unit, collision with floating objects floating in a shallow depth of the water surface or underwater during dredging operation or dredger propulsion is prevented, and the dredger is transported to land. Since collisions can be prevented from the ground or other objects, there is an advantage of providing an environment in which stable dredging can be performed as well as durability. |
