MDL-150D Crawler Anchor Drilling Rig

Description
This 150D anchor crawler drilling rig is of full hydraulic gyrator type. Its drilling depth is 130-170m, and drilling diameter 150-250mm. The crawler drill rig is mainly applied to urban subway, high-rise buildings, airport, ground source heat pump and other deep foundation pit for anchoring, jet grouting and dewatering. In addition, this 150D anchor crawler drilling rig is stable, efficient, versatile, and able to drill complex strata and deal with accidents.

Applications
Equipped with corresponding drilling rig, this crawler drill rig can satisfy the requirements of many kinds of construction.
①. The 150D anchor crawler drilling rig can be used for discharging mud slag with three-wing drilling bit. It is applicable to drill in soil strata, sand strata, etc.
②. This crawler drill rig is used for discharging air with air DTH hammer drilling. Due to high cost of the configuration and great pollution, the 150D anchor crawler drilling rig is just applied to the rock and broken layer construction.
③. It can be used for discharging mud slag with hydraulic hammer drilling. Due to low cost of configuration and small pollution, the rig equipped with BW-320 pump and hydraulic hammer is suitable for high moisture content construction, such as crushing egg layer, sand layer, etc.
④. It is of casing drilling and complex rod & casing drilling.
⑤. The 150D anchor crawler drilling rig can do single, double and triple jet grouting. It also can do fixed jet grouting and rotary jet grouting.

Advantages
1. According to the actual requirements, the torque and rotate speed can be adjusted to achieve best efficiency.
2. The route of shaft bracket is 3.4 meters, so the crawler drill rig can have complex rod & casing drill for 3 meters.
3. According to different strata, the gyrator can be adjusted to the corresponding torque to improve the drilling rig's adjustment.
4. Equipped with crawler chassis, high rotating platform, large diameter of the oil cylinder, 0.9 meters of the carriage and orifice support device, it is easy for this crawler drill rig to shift and locate. It is stable and reliable when drilling.
5. Due to shaft bracket automatically handling drill rod, this 150D anchor crawler drilling rig can reduce the intensity of the workers' labor. It is very efficient.

Features
1. The speed of this drill rig can achieve 170 circles every minute. It is increased by 20% compared with that kind of 135D.
2. The crawler drill rig is energy-saving and high-efficient. The efficiency is improved without increasing power.
3. With the rotary speed improving, the torque of 150D anchor crawler drilling rig is increased by 10% compared with 135D. And the highest rotary speed can achieve 7500NM.
4. Adopting new hydraulic system, the structure is simpler, the layout is more reasonable, and the operation is more human.
5. The efficiency of this crawler anchor drill rig is improved by 20% compared with that of 135D.

Components
The crawler drill rig is composed of crawler chassis, gyrator, shaft brackets, clamp holder, operating floor, pump station, sliding block and vice-concentration tower.
