The grounding of piling machine. Pile machine, three-phase asynchronous motor one day to play 2 piles piling machine and control box are constantly moving, how to ground? And is not a machine box. A gate or a few feet to ground is the five core. In three, the rest of the root, the zero line and the PE are useless? Thank you, predecessors, great God under the guidance of? In this way, the master said that the reception will be over, installed a leak protection, is not installed, the leak insurance does not need to ground ah?
Five core power cable, PE core wire may reach 16 square, in pile machine within 30 meters hit a 3 meter long galvanized angle (angle 50X5X3000), the head of a hole on the M10 (or M12) galvanized bolts, connecting 16 square BVR yellow green color line to the pile machine (repeat grounding), angle head (to prevent the hammer head welding deformation angle) a piece of iron, if you want to reuse (pull out in place again), can be connected with the hanging wire rope or a hook hole in angle steel.
The pile driver must be grounded reliably! Five core power cable, PE core wire may reach 16 square, in pile machine within 30 meters hit a 3 meter long galvanized angle (angle 50X5X3000), the head of a hole on the M10 (or M12) galvanized bolts, connecting 16 square BVR yellow green color line to the pile machine (repeat grounding), angle head (to prevent the hammer head welding deformation angle) a piece of iron, if you want to reuse (pull out in place again), can be connected with the hanging wire rope or a hook hole in angle steel.
Pile piling the opportunity to continue to move above the motor power is less, sometimes with a welding machine, control box in pile machine, according to the requirements of JGJ46-2005, must be "one machine and one gate of a protection"!
