SJ-20 Jet-Grouting Drilling Rig


Description 

Main characters:
1. Small working space needed: When the construction height is about 3meters, the effective length of drill rod can achieve 1.5 meters. Through adjusting the height of the machine, it is available to work in indoor space. And it is very convenient to move or remove the machine since the max weight of big part is only 300kg.
2. Applicable for wide range of layer: You can have different performance equipment in accordance with different layer type. The maximum output torque can reach 2000 Nm; the max pull-out force can reach 21kN. The machine can perform drilling by using hard metal drilling bits, DTH hammer, roller bits, etc. And in that way the machine can perform direct drilling construction in a majority of layer and then carry out jet-grouting drill for stake forming.
3. Applicable for wide range of processing: Except for jet-grouting processing, this machine can also be applied in anchoring processing construction.
4. Relative accessories: Clients can select different module function in accordance with different construction requirements. You can choose to purchase all relative accessories one time, you can also come back to buy suitable accessories according to the development of the construction situation, such as single, double and triple module, swing jet and fixing jet module, anchoring module.
5. Convenient for maintenance and operation: The operation is much more convenient, as we adopt full hydraulic technology and take down some important breakout on key technology link. For example, we add adjustable level module in jet-grouting lifting and anchor drilling.
6. Complete set of drilling tools: We develop a large number of jet-grouting drills to meet various demands of our clients in accordance with market demand such as drill of single, double, triple, swing jet and fixing jet.
7. Convenient combinations: According to the development of their respective development needs, clients can choose different combinations to get a better cost performance of equipment.
