ML-2 full hydraulic multi-function engineering drilling machine
Description:
ML-2 full hydraulic multi-function engineering drilling machine can be driven by electromotor or diesel engine. Power head and feed adopt hydraulic driven.
The rig is an anchor drilling machine and can realize the stepless speed change of power head, long stroke feed, the stepless regulation of feed rate and multi-function variable amplitude which means that the rig can drill a series of holes with different heights and angles at the same position.
It can be able to complete a variety of drilling process, such as carbide rotary drilling, auger drilling and all kinds of rotary spray(rotary spray in a certain angle, not rotating spray), and equip with display unit for verticality of drill tower, rotating speed of power head and lift speed.
It can be used in the following projects: deep excavation anchoring projects, anti-floating anchoring projects, foundation piles and geological disasters governance projects, etc.
Features:
1. With multi-function variable amplitude mechanism, it is convenient to drill a series of holes with different heights and angles at the same position.
2. Long feed stroke, high drilling efficiency.
3. With track chassis, easy and speedy to move.
4. The major components in hydraulic system adopt the imported brand and other components in hydraulic system adopt the domestic well-known brand. System is stable and reliable. They have a long service life.
5. Power head adopts hydraulic driven and can realize stepless speed regulation, and with high speed and low speed.
6. Variable hydraulic system with load feedback; high efficiency, low energy consumption.
7. With display unit for rotating speed of power head, lift speed and verticality of derrick, quickly and accurately to fix position.
8. Diesel-electric hybrid using dynamic range wider, reducing pollution and customer's construction cost.
