Expanding machine ramming pile construction machine equipment pile driver

Xuzhou Hagrix Machinery Manufacturing Co., Ltd. is a professional manufacturer of ram-expanded pile driver. The ram-expanded pile driver produced by our company is a hydraulic walking type with hydraulic walking and 360- degree rotation. The ram spreader adopts a gantry structure, and a 3.5- ton cylindrical rammer is lifted by a winch to expand freely into a hole in the protective pipe. The method of back pressure protection of the hoist sinks into the expansion pipe. The equipment is low in cost, high in construction efficiency, and free from pollution and noise.

 

The ram-expanded pile type is not only an effective measure to increase the bearing capacity of a single pile, but also can absorb a large amount of construction waste, clean the urban environment, and save the pile material.   Reduce project cost. In addition, the ram-expanded piles have easy to control construction quality,   Construction speed, short duration and other advantages. Therefore, in recent years, ram-expanded pile drivers have been rapidly promoted in the project and have achieved good economic benefits.   Environmental and social benefits.

 

The main configuration of boring machine is as follows:

1. The frame adopts gantry and slashes on both sides;

2, 50kN quick release type main hoist for lifting and tamping hammer quick release;

3 , 30kN auxiliary winch for back pressure and lifting casing;

4 , casing, usually with a diameter of 377mm- 426mm seamless steel pipe, the length of the design depends on the length of the pile, on the filling port and ear;

5 , hammer, hammer body length of about 4-5m , diameter of the hammer is slightly smaller than the diameter of the retaining tube, generally using a hammer weight 35kN , the hammer is connected with the fast-release main winch through the wire rope;

6. The chassis adopts hydraulic walking type, four outrigger cylinders, and two luffing rack cylinders, all adopting hydraulic control. The outrigger cylinder can realize self loading and dump truck;
