Use method of dredging sand

(1) Before starting, check the transmission system of the whole machine and the oil of the machine, and then start the diesel engine behind the conveyor belt, pull the clutch, start the diesel engine, slowly move the clutch, and adjust the speed to normal. Start the diesel engine before the zipper bucket.

(2) After starting the two diesel engines. Adjust the speed to the desired speed. Then release the arm brake. Slowly put it down, such as the sand in the hopper more than 2/3, can stop the lower, to 1/3 of the time to support the arm. When the arm and the water into a 45 degree Angle (that is, about 5 meters), should park the arm. At this time, the amount of sand in the hopper to use traction control, forward to check the amount of sand in the bucket, forward and backward to be flexible, such as in the case of sand collapse mechanical work difficult or pull not to loosen the traction rope, so that the ship back, until digging. If there is a large stone or mud layer under the water, the ship will have violent vibration phenomenon. At this time, the dredging arm should be lifted immediately and the obstacles should be avoided.
