zoomlion rotary drilling rig
CE-approved stage IV engines and high flow pumps that provide high productivity when matched with the tools and they offer outstanding performance in drilling large diameter deep footings without support or reinforcement by rock bolts, backed up by an automatic air drilling system.Varied strategic construction conditions such as soil solidification, etc.Modern features include a high torque hydraulic motor which enables fast mechanized drilling in quick missions; meanwhile, a full automated drilling system guarantees speed and accuracy.The modular design of the rig and Telescopic Kelly Bar make it a very flexible machine, suitable for different terrains and stages of project.Applications vary from big infrastructure projects down to urban construction, where there are stringent restrictions on space and noise pollution.
