280 kN.m Torque Piling Rig
Automatic Crowding Control System
Controls crowding system, which enables piling rig SR280R-II to achieve high efficient drilling at rock layers.
Step-less Crowding Force Regulation
Crowding system adopts advanced electric-proportional control components, which can step-lessly regulate crowding force and effectively improve stability of the rig.
Effectively Absorb Shock Energy
The piling rig's working equipment adopts particular 5-level anti-shock technology, which increases the anti-shock capability by more 30%, and high strength steel increases mast strength by 30% to 40%.
