Features:
The truck chassis is adopt the 8×4 special chassis of brand DONGFENG TRUCK, the main transmit, transmission power, gearbox, sets of windlass, mud pump, sewage pump，mast are setup on the chassis.
This rig is a rotary drilling rig with directional circulation, which is equipped with BW850/4-80 mud pump. It adopts the slurry as the washing fluid, it can drill on clay, sand and rock if it is equipped with a good drilling bit.
The power of drilling rig comes from the truck engine; the rig sets up distribute implement and hydraulic system.
We can set up the spare electric engine and clutch implement according to client's requirement, so that the rig can work with diesel engine or electric engine.
We can set up a generator (30kw) , so that it is convenient to illuminate or work at night.
The adding pressure implement is hydraulic, so it has a high efficiency when the rig drill on mud rock and weathering formation through using the adding pressure implement.
The master driving of rig is mechanical, the four jacks and mast are hydraulic operated. Distribute box, sewage pump, master driving clutch system are air operated.
The appearance of rig is pretty. It has a high efficiency because of having a larger torque of the turntable, it is mainly used for water well, construction, national defense building foundation, geological exploration, geothermic well and other foundation working. It is popular with domestic and foreign clients.
Machine maintenance:
1. At the end of each work class, the dirt on the surface of the machine must be removed.
2. It is strictly forbidden to dismantle and unload the working surface, except for the case that the components are easy to handle, so as to avoid losing the key parts of the parts and damaged parts.
3. Regularly add oil to the oil mister to ensure that the control valve, wind motor and impactor have good lubrication.
4. The gearbox is lubricated with calcium-based grease oil. Regularly add lubricant. The lubricant accounts for 1/3-2/3 of the gap of the box to ensure the lubrication of the gearbox.
5. In the joint part, the friction between the carriage and the pressure plate and the slide plate is caused by the relative movement of the slide plate and the carriage. When the friction is slightly damaged, the adjustment pad under the pressure plate can be removed. When the wear is heavy, the pressure plate, the slide plate or the carriage can be replaced. ,
To ensure high drilling accuracy.

Measures for the use of the water well rig during the running-in period
1. The operator should receive training and guidance from the manufacturer, have a thorough understanding of the structure and performance of the rig, and obtain certain operation and maintenance experience before operating the machine. The product maintenance and repair instructions provided by the manufacturer are the necessary information for the operator to operate the equipment. Before operating the machine, be sure to read the maintenance instructions and operate and maintain according to the requirements of the manual.
2. Pay attention to the working load during the running-in period. The working load during the running-in period should not exceed 80% of the rated working load, and the appropriate workload should be arranged to prevent the overheating caused by the continuous operation of the machine for a long time.
3. Pay attention to the indications of each instrument frequently. If an abnormality occurs, it should be stopped in time to be excluded. If the cause is not found, the operation should be stopped before the fault is not eliminated.
