R&D quality for the important accessory of pile driver

Hydraulic road guardrail pile driver, which important parts are hammer, pile frame, hammer lifting cylinder and pulley set of four sectors. Hammer quality is the most important , the weight of the hammerhead is 1 /6 - 1/8 of accessory, which affects the working efficiency of the pile driver. As for the engine power, hydraulic system pressure, pile frame layout and different material usage, etc., depend on the quality of the hammer. During operation, the hydraulic valve is controlled by the stroke so that the pulling hammer of the pulley block acts on the preset height through the oil cylinder, and then the hydraulic valve is prohibited from entering the oil and the main oil return path of the lifting cylinder is closed to allow the hammer to freely fall by gravity. Fragmentation or hammering function.
