HTW

The HTW-Series hydraulic water well drill is a multi-functional drill rig driven by internal combustion engine, the drilling power is provided by hydraulic system except for impacting and the hole cleaning wind. It is convenient and efficient to operate. The drill consists of many model parts, which is easy to change. The machine is widely used for deep water well drilling operation in the mountainous and plain areas.
Characteristics:
Mobility is one of the main advantages of the water drill.
The feed and rotary head were driven by hydraulic motor, therefore, the air and oil consumption and total drilling cost are lower.
The hydraulic feed and rotary head put out the biggest feeding force and largest rotary torque, which makes it more suitable for operation in complex worksites
Equipped with highly efficient rods changer and mud mixing system
The carriage with rollers provide for minimal wear to the drill guide.
Equipped with two hydraulic clamps is easy to load and unload drilling rods and improve efficiency.
The diesel engine and main hydraulic parts adopt imported products or famous domestic companies.
The special compensation device makes a full protection of drill rod threads.
Equipped With jib hoist and standard oil drilling rod
