GL-II ZF Direct & Reverse Circulation Trailer Mounted Drill Rig
●Main features and applications:
◆ Drilling wells for urban and rural life
◆Drilling wells for agricultural irrigation and industries
◆Drilling construction engineering holes, piling
◆ Drilling geothermal pump wells
◆ Exploration drilling and geological survey
● This type of drill rig is direct and reverse circulation drilling rig.It can move place to place by mounting a trailer or truck chassis, which makes more convenient for construction work. Equipped with hydraulic up-down mast, making it easier for mast up and down.
● Diesel engine is standard configuration for this drill rig. It can be also driven with three-phase AC generator as for clients’ requirement. It can be driven not only through diesel engine, but also by external electric power,which fully achieve “ diesel engine and electric motor dual use” dual power drilling work.
● We have patent for our drill head,independent design and manufacture, enjoy the intellectual property rights. The main components such as hoist, gear box, tower and chassis are independent R & D and production of our factory. This model is a mature product of our factory for many years of painstaking development, stable and reliable performance, praised by customers at home and abroad.
● This model can be used for mud drilling and air drilling method,which is suitable for clay layer,sand and rock drilling.
● Big torque, large lifting force, strong power,easy operation,convenient on-loading drill pipe, high efficiency,it is the best choice for users.
