Product introduction of roof bolter mdl-135d

Anchor drill mdl-135d is a high-efficiency drill developed by Wuxi Zhimai Construction Machinery Co., Ltd. according to domestic subway, high-rise building, airport, ground source heat pump and other deep foundation pit for anchoring, rotary jet and dewatering lock. The drilling rig is integral and equipped with crawler walking chassis and clamping shackle. The root canal drilling tool can be used to follow the casing to form a hole, and the functions of lifting and rotary jet are increased.

Introduction to mdl-135d anchor drill

Enclosure: the added enclosure makes the machine more scientific in appearance and protects the key hydraulic parts from pollution;

Power head: the rotary device of the drilling rig is driven by double hydraulic motors, with large output torque and lower rotation center than similar products, which greatly improves the drilling balance of the drilling rig. The equipped expansion joint can greatly prolong the service life of drill pipe thread;

Outrigger: not only avoid damage to the oil cylinder, but also enhance the support strength;

Datong hole high pressure resistant Faucet: a necessary device for expansion head construction;

Console: split console to make operation easier and avoid misoperation;

Crawler: longer and stronger crawler, which can effectively prevent subsidence and adapt to a wider range of strata;

Lifting: the height of the orifice can be adjusted, which is no longer dependent on the height of the working face;

Automatic turntable: it is easier and more convenient without manual labor;

Heat dissipation system: the heat dissipation system is optimized according to the customer's local special working conditions to ensure that the temperature of the hydraulic system does not exceed 70 ℃ when the outdoor temperature is 45 ℃.

Construction characteristics of roof bolter mdl-135d

·Special pipe following drilling tools (drill pipe, casing and eccentric bit) can be selected to open holes with casing wall protection in unstable formation, and conventional ball tooth bit can be used to finish the hole. High drilling efficiency and good hole forming quality.

·The drilling rig is mainly used for anchoring and support of deep foundation pit. It can also carry out rotary jet grouting construction through the replacement of rotary jet grouting module. In addition, the machine also has strong performance in the construction of geothermal holes, dewatering wells, micro steel pipe piles and micro cast-in-place piles.

·In addition to the crawler chassis, clamping shackle and rotary table, we also provide users with rotary jet module and other accessories. Users can select and stack when ordering the drilling rig, so that our drilling rig is more suitable for your project.
