MDL-120D3 Crawler Anchor Drilling Rig

Properties of Crawler Drilling Rig
1. This drill rig is a type of crawler jet grouting drilling equipment, and it is proven to have high safety coefficient, high construction efficiency and easy to move.
2. Our anchor drilling rig can use one drilling rod to construct a soil nail with 9 meters.
3. When using this crawler drilling rig, its power head should be maintained and lubricated, which can prolong the service life of the bearings and also can effectively reduce maintenance costs.

Description
The anchor drilling rigs are suitable for the following fields of soft soil foundation improvement, dam reinforcement, foundation excavation, anti-floating anchor, soil nails, high pressure jet grouting, swing jet grouting, directional jet grouting, tunnels, railways and highways.
The crawler drilling rig also can be used for mini cast-in-place pile, micro steel pipe pile, precipitation well and geothermal construction. Equipped with winches, this anchor engineering drill rig can crane anchor rod and drill tools.

Features of Anchor Drilling Rig
1. This crawler drilling rig adopts a detachable assistant tower with 7 meters high.
⑴ In the jet grouting construction, it can take the place of overhead rotary jet, which can reduce times of dismantling the drill tools, and potential quality hazard.
⑵ The assistant tower can be detachable, which will not influence the other functions of the drill rig.
⑶ This anchor drilling rig saves both time and labor during the short anchor rod construction.
2. Large through-hole rotator is mounted on this crawler drilling rig.
⑴ Through-hole diameter can reach 92m, which makes sure that the 89 drill rod can pass accessibly. The ordinary 89 steel tube also can be used for anchor drilling rod construction.
⑵ This crawler anchor drilling rig adopts hydraulic chuck structure, which makes the replacement of the drilling tools freely and conveniently. No worry about various transition joints.
⑶ Equipped with large torque power head combining with our strengthened jet grouting drilling tools, our anchor engineering drill rig can be used in most formations.
3. This crawler drilling rig chooses and uses a crawler chassis with lower ground pressure, even in softer ground, it can operate smoothly.
4. This crawler anchor drilling rig adopts orifices guiding device.
⑴ The drilling tools are easy to be dismantled in the jet grouting construction. Meanwhile, it can ensure the angle and verticality.
⑵ This device may improve the force situation of the steel pipe or drill tool in anchoring construction.
⑶ Special slewing mechanism may reduce the wear of the drill tools.
5. This crawler drilling rig can match with air compressor, high pressure injection pump, mud pump, single, double and triple jet grouting.
6. As the first manufacturer of anchor drilling rigs and jet grouting drilling rigs, we manufacture our drilling equipments in batch production.
7. Our drill rigs are economical and practical because of controllable manufacturing cost.

Composition of Crawler Drilling Rig
This drilling equipment consists of crawler chassis, rotator, propelling frame, holder, operating board, pump station, carriage and assistant tower.
