Detailed description

Description

Balanced power and strong rock penetration ability

With a standard high torque of 280kN · m and a high-power imported engine, it has sufficient reserves of pressure and lifting force, making it easy to cope with pebble layers and strongly/moderately weathered rock layers. It also takes into account efficient drilling in ordinary soil layers and hard rock construction, with strong versatility.

High construction efficiency and fast hoisting speed

The main winch has excellent lifting speed and a fast rhythm for lifting and lowering drilling tools; The hydraulic system responds sensitively, with smooth composite actions and high efficiency in rod tilting, soil throwing, and pore forming cycles, resulting in outstanding production on the shift.

Good overall stability and high-quality drilling

Widening and lengthening specialized chassis, large-span telescopic tracks, low center of gravity design; Mast rigidity reinforcement+intelligent verticality control system, with minimal shaking during deep pile and large-diameter construction, and precise verticality of drilling holes.

Fuel efficient and durable, with low operation and maintenance costs

Load sensitive energy-saving hydraulic+power intelligent matching mode, powerful under heavy loads and fuel-efficient under light loads; High strength design of key hydraulic and structural components, single row rope drum to reduce wire rope wear, and long replacement cycle for vulnerable parts.

Flexible transition and wide adaptability to the venue

The modular design of the entire machine allows for short distance transportation without the need for large disassembly, and the transportation dimensions are compliant; The body layout is reasonable, and it can operate normally on urban and rural construction sites, as well as small construction sites.
