Advantages of ST400 water well drilling rig:

1. Traveling device: The travelling motor is equipped with a reduction gearbox, which is durable and has a long service life.

2. Hydraulic oil pump; Parallel gearbox design, separate oil pump, sufficient power supply and reasonable distribution, unique design of hydraulic system, simple maintenance and low cost;

3. Power head device; the gearbox is integrally cast, and the dual motors provide power, high torque, durability, and low maintenance costs;

4. Rig chassis; professional excavator chassis, durable, large bearing capacity, wide chain plate, small damage to hard road;

5. Lifting force; design composite boom, small boom size, long stroke, double oil cylinder lifting, large lifting capacity;

6.Each rig's lifting boom is equipped with a limiter to protect the safety of the oil cylinder and ensure safety at work;

7. Each hydraulic tubing is covered with a protective jacket to make the tubing longer in service life.

ST400 water well drilling rig:

* The series of drill rig adopts a excavator crawler chassis and has strong off-road performance. The independent module design allows the drill to be mounted on the truck to increase its mobility. Two speeds of rotating and advancing speed can meet the different needs of soil and rock drilling. Combined positioner, the positioning disc can be adjusted and replaced according to different types of drill pipe and impactor, so as to ensure the accuracy and reliability of the positioning and centering. The hoisting mechanism is convenient for hoisting of drill pipe and impactor, so as to reduce the labor intensity.
* This machine can be applied to various strata, used in water well engineering, geothermal well, anchor pile hole and so on, and can be used with follow-pipe drilling. It has the advantages of whole machine hydraulic control, automatic loading and unloading drill pipe, crawler type chassis, large horsepower diesel engine, four hydraulic support leg balance, stronger terrain application ability and so on.
