Product Overview
·High efficiency, fast speed, and labor saving in pile breaking
The hydraulic pile breaking machine provides pressure to multiple oil cylinders of the pile cutting machine through a power source. The oil cylinders directly drive the drill rod, while squeezing the pile body to cut off the pile head. During the construction process of the pile breaking machine, it is easy to operate, efficient, low noise, and cost-effective, suitable for pile group construction projects. The pile breaking machine adopts a highly modular combination, which is connected to modules through a pin shaft. By combining different numbers of modules, a certain range of diameter pile heads can be cut off.
Hydraulic pile breaking machine for cutting: such as cast-in-place piles, prefabricated piles, etc; From the shape of the pile cutting head, it can be divided into circular pile breaking machines and square pile breaking machines. Pile breaking machines are widely used in high-speed railway bridges and civil engineering pile foundation projects. Generally, circular pile cutting machines are suitable for pile diameters ranging from 250mm to 2500mm; The square pile cutter is suitable for pile edge lengths of 250-650mm and can meet the requirements of various large-scale foundation construction.

1. Unscrew the oil injection port cover and transfer the hydraulic oil
Inject (ISOVG32, 46, 68 or equivalent hydraulic oil) and observe the oil level in the oil level gauge. The oil level should be submerged to the top mark of the oil level gauge. If the bottom mark of the oil level gauge is found during daily use, it indicates insufficient oil in the tank. Please add oil before use, otherwise it may cause system instability and pump damage. Insufficient oil damage is not guaranteed.
2. Unscrew the fixing screws on the side junction box of the motor, remove the cover, wire according to the wiring diagram shown on the motor nameplate, and ensure that the input voltage does not exceed the maximum allowable operating voltage of the motor.
3. Connect various hydraulic pipelines and electrical control circuits.
4. Start the motor, turn it off after about 1 second, and observe whether the motor rotation direction is consistent with the pump's indicated rotation direction. The motor is normally clockwise. If it is not consistent, please swap any 2 of the motor's 3-phase wires. If the motor is not in clockwise, please do not use it for a long time, which may cause the oil pump to burn out and is not covered by the warranty. (The motor does not rotate clockwise and the hydraulic station will not have pressure and cannot be used normally).
5. Start the motor again. The system can be used (when using it for the first time, please let the system run empty for a period of time to facilitate the elimination of air in the pipeline).
matters needing attention
It is necessary to follow the principle of breaking piles from top to bottom, and the height of the pile is determined by the concrete grade. It is recommended that the section of each pile should not exceed 40cm
1. During the process of pile breaking, it is prohibited to forcefully lift or pull the drill rod before it is fully retracted into the cylinder body. (The above picture shows the incorrect operation method, which can easily break the drill rod and guide flange.)
2. It is prohibited to use the pile breaking machine as a lifting plane to lift concrete blocks (the above picture is a serious incorrect operation method, as the pile breaking machine is prone to damage)
