Highly adaptable JINT SD20 Rotary Drill Rig

Power and Drilling Performance

200kN · m standard torque, speed range of 8-30r/min, suitable for balanced soft and hard soil layers, easy to drill in soft soil layers, and can stably cope with gravel and moderately weathered rock layers.
200kN winch pressure/pulling force, 5-meter pressure stroke, deep hole is not easy to get stuck in drilling; The main winch has a high single rope tension, fast drilling speed, large amount of soil taken in a single operation, and high construction efficiency.
Equipped with Cummins QSL9 engine of 194kW, it has sufficient power reserve, stable fuel consumption control, and high reliability for long-term continuous operation.

Advantages in pore forming accuracy

Standard electronic control automatic leveling, mast verticality monitoring, hole verticality ≤ 0.5%, real-time compensation for soft foundation settlement and uneven site, high pass rate of pile foundation acceptance, reducing rework costs.

Chassis and site adaptability

Jintai’s JT70 widened track chassis has a low ground to ground ratio, making it difficult for vehicles to sink on muddy and soft ground; The overall weight distribution of the machine is reasonable, with strong anti overturning ability for large aperture operations and good stability for narrow construction sites, without the need for additional large amounts of steel plates.

Hydraulic and Control System

Load sensing fully hydraulic system, power is distributed according to demand, reducing ineffective power consumption; Centralized electronic control operation in the cab, user-friendly and easy to operate, with lower fatigue levels during long shifts.
The mast is adjustable from multiple angles and can support inclined pile construction, providing a wider coverage of project conditions.
