Automatic hole alignment SANY SR150 Rotary Drill rig

Power and construction performance

150kN · m standard torque, dual motor dual reduction power head, capable of handling clay, sand, gravel, and shallow weathered rock layers
The maximum pile diameter is 1500mm, the maximum depth of the machine lock rod is 55-56m, and the friction rod is 44m, covering the vast majority of small and medium-sized pile foundation working conditions
Kawasaki negative control dedicated chassis hydraulic system, main winch merging and acceleration, construction efficiency is about 10% higher than similar models, and the fastest winch is 82m/min
The mast parallelogram leveling mechanism has high accuracy in drilling verticality and is suitable for construction sites with strict requirements for pile positions in municipal and building construction

Fuel consumption and economy

Isuzu original engine, load sensing power adaptive, fuel consumption reduced by 5-10% compared to the old model, long-term dry shift fuel saving advantage is obvious
The whole machine weighs about 46 tons, and the same torque model has a light weight, easy transfer, low transportation cost, and can be shipped as a whole under most working conditions with less dismantling
Small and medium-sized models have moderate maintenance and accessory costs, high resale value, and fast return on investment

structural reliability

Mast box type reinforced structure, with strong resistance to torsion and bending; All hinge point self-lubricating bearings reduce maintenance frequency
Finite element fatigue verification of key components, non-destructive testing, robot welding, low failure rate, and short downtime for maintenance
The winch adopts Lebus rope groove, which prevents the steel wire rope from being tangled and squeezed, and extends the service life of the steel wire rope
