Impact resistance SR155 Rotary Drill Rig

Power adaptation for small and medium-sized pile foundations, with strong versatility in working conditions

Rated output torque of 155kN · m, maximum hole diameter of 1.5m, maximum drilling depth of 55m (friction rod)/44m (interlock rod); The pressure and hoisting lifting force are abundant, which can cope with clay, sand, pebble layers and other strata. The construction efficiency of soft soil and ordinary rock layers is outstanding, and it is suitable for the majority of civil building pile foundation needs.

Smooth compound movements and high drilling efficiency

The electrically controlled negative flow hydraulic system allows for synchronous linkage of rotation, drilling, and pressurization, ensuring smooth and seamless operation without any lag; The speed range is adjustable from 5 to 35rpm, and the speed can be switched according to the formation. The drilling cycle is faster, and the number of piles formed per day is better than that of competitors of the same tonnage.

The whole machine has balanced weight distribution and excellent operational stability

The total weight of the machine is 48 tons, with a customized widened track chassis and low grounding pressure; Small construction sites and excavations are not prone to tipping over, and the mast can be adjusted from multiple angles. The adaptability of slope and confined space pile foundation construction is good.
