SJW-60 High Pressure Jet-Grouting Drilling Rig


Description:

This SJW-60 high pressure jet grouting drilling rig is designed by Wux Anmai Construction Machinery Co., Ltd on the basis of SJW-60. It has more fuctions and better designment.
Applications
1. weak ground construction              2. waterproof curtain
Main characters:
1. Assembly 20m sub-tower, which is detachable.
1) When conduct jet-grouting construction, through the high tower assembling, it can reduce assembling and disassembling times and then help saving time and material.
2) When conduct anti-floating anchor, it can help save extra lifting fee by using its own lift.
3) When conduct inclining anchor cable construction, the auxiliary tower can be detached without influencing the other functions of the machine.
4) When conduct short anchor construction, the machine can achieve straight drilling through, which can be really time saving and convenient.
5) The auxiliary tower was standard designed, 4 sections can be freely combined into 5meters, 15meters, 20meters.

2. Power head (through-hole type)
1) With its 92mm diameter, it can guarantee clear pass for dia89mm drilling rod. It can also meet the requirements of triple pipe jet grouting construction and anchoring.
2) With its hydraulic crawler chuck, it is much more convenient and easier for changing the drilling tools.
3) With its large torque of power head and our intensive drilling tools, it can achieve drilling through without making any guiding holes, which can save a lot of time.
4)It adopts large-torque rotary head, that when equipped with our enhanced type jet grout drilling tools, it can be really time and cost saving without making guiding holes in most of working layers. 

3.It has a new function of digital readout.
1) Operator can look into the digital display instrument more intuitively to know the rotary speed and lifting speed while in construction.
2) It has a better grasp of design requirements for construction.
3) Higher construction effeciency, easier and more convenient operation.
