MDL-135D Crawler Anchor Drilling Rig

Description
The 135D crawler anchor drilling rig is of full hydraulic gyrator type. Its drilling depth is 100-140m, and drilling diameter 150-250mm. This China's engineering drill rig can be used for anchoring, which is applicable to rod boring, casing drilling and complex rod & casing drilling. It can be used for jet grouting, which is applicable to single jet grouting, double jet grouting and triple jet grouting. It can be also used for foundation pit de-watering and mini-type filling pile.

Applications
The 135D crawler anchor drilling 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. This engineering drill rig can be used for drilling geothermal hole and well, and can be used for exploring.

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 135D crawler anchor drilling 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. The gyrator of 135D engineering drill rig adopts double hydraulic motor drive. With large output torque, the rotary center was lower than that of similar products, greatly improving the stability of drilling rig.
5. 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 135D crawler anchor drilling rig to shift and locate. It is stable and reliable when drilling.
6. Due to shaft bracket automatically handling drill rod, this 135D crawler anchor drilling rig can reduce the intensity of the workers' labor. It is very efficient.

Features
This 135D crawler anchor drilling rig is stable, efficient, versatile, and able to drill complex strata and deal with accidents.
1. Equipped with corresponding drilling rig, the China's engineering drill rig can satisfy the requirements of many kinds of construction.
2. The 135D crawler anchor drilling rig can be used for mud slag discharging with three-wing drilling bit. It is applicable to drill in soil strata, sand strata, etc.
3. This China's engineering drill rig is used for air discharging with air DTH hammer drilling. Due to high cost of the configuration and great pollution, the 135D crawler anchor drilling rig is just applied to the rock and broken layer construction.
4. It can be used for mud slag discharging 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.
5. It is of casing drilling and complex rod & casing drilling.
6. The 135D crawler anchor drilling rig can do single, double and triple jet grouting. It also can do fixed jet grouting and rotary jet grouting.

Components
The 135D engineering drill rig is composed of crawler chassis, gyrator, shaft brackets, clamp holder, operating floor, pump station, sliding block and vice-concentration tower.
