What do you need to prepare before dredging

Dredging sand specially used for river sand mining, is a relatively environmental protection mining machinery in recent years, however, although relatively environmental protection, but also need us to do a good job of checking before dredging sand, to avoid equipment damage and environmental pollution.

1. Before the machine, check the transmission system and oil of the whole machine, 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 of 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, should park the arm. At this time, the amount of sand in the hopper is changed to traction control.

3, dredging sand forward to check the amount of sand bucket, forward and backward to 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.

Our company is a professional production of dredging sand manufacturers, reliable product quality, welcome new and old customers to visit our company cooperation, and seek common development.
