What's the special use of a pile driver?
Moreover, the torque of the hydraulic power head is 2-3 times as much as that of the ordinary three ring power head. It is more suitable for complex formation than the traditional long spiral, and the construction efficiency is more efficient. Long spiral drill in the type piling machine is the use of a more extensive, and for starting current understanding, we can get better in the construction layout, so as to avoid the occurrence of the voltage is not enough at the time of construction.
There are two main types of pile driver used at present: diesel hammer pile driver and long spiral drilling rig.In general, long spiral ring power head motor starting current depends on the specific circumstances, if the full voltage starting with load, the starting current is 5-7 times the rated current of the power supply. The construction of their equipment.
In addition to see how much power head in the face of tricyclic sticking case, two start if exceeds the rated current of it easily after all, a burning motor, power head is not cheap, suggest to consider all hydraulic power head, the power head is three was a bit expensive, but in the face of the card when drilling, two times can start easily and smoothly, the impact of the power grid is very small.
