Intelligent electronic control JINT SH32A Rotary Drill Rig

Power and hydraulic system

KN ・ m rated torque, maximum hole depth of 85m, strong construction capacity of soft and hard stratum and moderately weathered stratum
Cummins QSM11 engine, 266kW high power, matched with multiple pumps in parallel+Kawasaki special main valve, high power utilization rate, small system pressure loss and balanced oil consumption
Full-power intelligent electronic control, load-sensitive hydraulic pressure, drilling pressure of 250kN, lifting force of 300kN, difficult to jam the deep hole pulling drill

Structure and Stability

JT85 retractable crawler chassis, retraction of 3.4m, spreading of 4.58m, consideration of transition in narrow site and wide operation, strong anti-overturn ability
Large triangle mast support structure, extending the lower mast, milling and forming the whole guide rail, high mast rigidity and good drilling perpendicularity precision
Laminated type detachable counterweight, small turning radius, convenient disassembly and transfer, and the counterweight can be increased or decreased according to different working conditions

Core components of winch and power head

The folded wire rope groove structure of the main winch reduces the abrasion of the steel wire rope; Standard tension sensor, real-time monitoring of drilling tool load, anti-over-roll overload
Single-stage deceleration power head, simple structure and low failure rate; Three groups of replaceable wear-resistant sliding plates, long wear-resistant life of carriage and lower maintenance cost in later period
The crown block integrates height limiting and sounding sensors, and the hole depth and drilling tool position are displayed in real time, so the construction visualization is high
