Multifunctional drilling


Various drilling techniques can be used on SL400QS water well drilling rig, such as: down-the-hole drilling, through-air reverse circulation drilling, air lift reverse circulation drilling, cutting drilling, cone drilling, drilling with casing and core drilling under development, etc. The drilling rig can be equipped with mud pump, foam pump and generator according to user requirements. The rig also comes standard with various winches.

High efficiency


Due to full hydraulic and top drive type rotary feeding lifting that are suitable for various drilling techniques and drilling tools, the operation is convenient and flexible, with fast drilling speed and short auxiliary time, so the efficiency is high.

Low cost


Drilling on the rock is based on the DTH hammer drilling technology. DTH rock drilling has high efficiency and the single-meter drilling cost is lowest.

High outriggers crawler type



The high outriggers are convenient for loading and transportation, and can be loaded directly without a crane. Crawler walking is more suitable for muddy on-site movement.

Unique positive and negative axial pressure adjustment


The best impact efficiency of various DTH hammer has the best matching axial pressure and speed. During the drilling process, as the number of drill rods increases, the axial pressure on the drill hammer is also increasing. Therefore, the positive and negative axial pressure valves are adjusted during construction to ensure that the drill hammer can obtain the best axial pressure. The impact efficiency is the highest at this time.

Function of lubricator



High efficiency and durable lubricator and oil mist lubrication pump. During the drilling process, the high-speed drill hammer is lubricated at all times to maximize its service life.

Rig chassis



SL400QS water well drilling rig can be crawler mounted self-propelled chassis, also can be truck mounted self-propelled chassis or trailer mounted chassis.

The second-hand machine has the highest value in the industry



The main components of the drilling rig are imported brands, and SL400QS water well drilling rig made of high-quality high-strength low-carbon alloy steel, which increases the overall strength and is super wear-resistant. There is also the most important hydraulic system, which is very valuable.
