In recent years, with the significant investment made by the state in sewage treatment and water conservancy construction, the demand for excavator pile drivers in high-level excavators has been increasing!
At present, there are not many enterprises in China that can independently research and develop new products. Most of them import from abroad or simply purchase parts and make shoddily by themselves. The failure rate is high and it is a common phenomenon that parts are hard to purchase. So, how can one buy a satisfactory excavator pile driving equipment?
No.1: The selection of the excavator pile driver is based on the model of the excavator and the flow and pressure of the large pump. The hydraulic motor of the excavator pile driver must have sufficient pressure-bearing capacity. Generally, customers will choose the cheaper pile driver. In fact, you may not know that precisely because you focus on the price, some unscrupulous and unscrupulous manufacturers will substitute the inferior for the superior. For example, if you have a Doosan 360 excavator, It should be equipped with a hydraulic motor of a larger specification and other supporting components. However, you may not know that you actually bought a pile driver for a 20-ton excavator. Whether it can be used or not, it can definitely be used. It’s just that during installation, they tampered with you by lowering the pipeline pressure to ensure the working pressure required by the motor. The excess oil pressure was returned to the oil tank. In this way, customers generally won’t notice. What is reflected is that the striking force and vibration force are much smaller.
No.2: The excavator pile driver is equipped with a clamping function, which is used to clamp the required piles (such as concrete piles, steel sheet piles, channel steel piles, wooden piles, etc.). Currently, most domestic sellers do not have the technical capability to clamp the heavy piles to be driven. Generally, the piles will fall off after being clamped for 8 seconds. Just think about it, in the working condition where the piles need to be moved, who can guarantee that the pile driving will be completed within 8 seconds? This undoubtedly adds to the safety and trouble of construction. Many customers can only use two excavators to drive piles, one for hoisting and the other for driving. The cost increases and the efficiency is slow.
No.3: Excavator pile drivers usually have a rotary function, which is also a key area for improvement. Generally, the main function of a pile driver is to drive piles, while the rotary function is mainly used for steel sheet piles. Therefore, most manufacturers usually replace the rotary motor with a domestic one.
