Product selling points

Dedicated hydraulic telescopic crawler chassis, heavy-duty slewing support, the whole machine is stable and high;

Adopting large triangle luffing mechanism to ensure the stability of construction in hard ground with large holes and deep piles;

The front single-row rope main hoisting structure greatly extends the life of the wire rope and reduces the use cost;

Cummins turbocharged engine has three-speed control. Users can select gears according to working conditions, so that one rig can achieve the effect of three engines;

The power head has a normal mode and a rock-entry mode, which respectively operate on soil and rock layers, which improves the construction efficiency;

Optional hoisting pressure and casing driving functions to meet users' various needs;

Centralized lubrication system as standard, convenient maintenance;
