Precautions When Using Electric Vibratory Pile Hammer

To start the electric vibro hammer, adjust the landing gear's hammer mechanism to the starting position. After lowering the landing gear rocker until it hits the lower bumper, the starting hook extends into the cylinder to hook the upper piston. Then, raise the landing gear, driving the upper piston upward. When the rocker hits the upper bumper, the starting hook retracts, the upper piston drops, and power is applied, triggering the explosion. If the electric vibratory pile hammer doesn't operate normally after one start, repeat the process several times until it operates normally and continuously.

After the electric vibratory hammer is operating normally, raise the landing gear to more than 2 meters above the top of the upper cylinder. Do not allow the landing gear to drop while the pile hammer is operating. If the landing gear drops during operation, it will hit the bumper on the pile hammer, causing the starting hook to extend into the cylinder and hook the piston, potentially causing damage. Therefore, extreme caution is essential.

When encountering soft soil or silt formations, the electric vibratory pile hammer may stall or fail to start. In this case, pull the control rope to the power-off position, lift the upper piston and let it fall freely several times (equivalent to drop hammer piling). When the pile has a certain resistance, it can be started. In this case, if the electric pump is not pulled to the power-off position, too much electricity will accumulate in the battery, making starting more difficult and easily causing the battery to produce a false charge.
