Product Detail
KT5000 full hydraulic power drilling high drilling machine good performance,reasonable price and have good market

KT5000 core drilling rigs is a new product developed by our company in 2006. Its main technical parameters are as shown in the table below. 

KT5000 Type fully hydraulic unit drilling machine is mainly composed of power unit, guide frame, chassis, hydraulic system, electrical system and drilling tool system.

1.Power Unit

Power unit is driven by four pumps and four motors, with the Max. rotating speed of 12r/min, and the Max. torque reaching 400kN.m. It can bear a lifting capacity of 300t and realize gas lifting counter-circulation construction. Special sealing ring is adopted in its inside. The seaking technique for shielding machine is appplied to the engineering drilling machine for the first time, solving the slurry leakage problem occurred in construction.

2.Guide Frame

Four-pillar gate-tape structure is adopted for the guide frame,which can bear a torque of 400kN.m. On its upper part it is equipped with the manipulator and auxiliary hoist which are convenient to remove the drilling tool in construction.


Double layer chassis is adopted in the large-type engineering driling machine for the first time, with compact structure. The drilling bit with a diameter of 5m can go down when the upper chassis is moved away.

4.Drilling Tool System

The drilling tool system is composed of drilling bit, gas cell drilling rod, additional drilling rod, additional weight, centralizer, and standard drilling rod, with a diameter of the through hole of 350mm. Movable duct structure is adopted, therefor, the problem of the strength of the drilling rod is solved.

5.hydraulic System

Four-pump and four-motor constant power variable loop is adopted for the main loop and the driving power reaches 300kW. The hoisting loop is combined with the main loop to reduce the energy consumption. In addition, the cooling loop and automatic drilling loop are provided, which can great satisfy the construction requirements

6.Electrical System

All the actions of the drill are performed by the electrical buttons, greatly reducing the labor strength of the working personnel. PLC technology is adopted so that the torque, pressure and lifting weight of the drill can be timely abserved. Moreover, the application of remote control technique greatly facilitates the construction.

7.Operation Room

The large operting room is provided for the drilling machine, and all the electrical systems are arranged in it. The operating room is provided with air conditioners and the working environment of the operating personnel is improved.

 This drilling machine has high drilling efficiency,good performance,reasonable price and have good market in the world. At present, large bore drilling machines are mostly used in the engineering bridge piles in China, and its torque is below 300kN.m. With the consciousness rising of the invironmental protection and the growing increase of sewage treatment projects in the recent years, the existing big bore drilling machines can not satisfy the requirements. KT5000 Type fully hydraulic unit drilling machine developed by our company, with an output torque of 400kN.m and a drilling diameter of 5m, is the largest drilling machine of the same kind in China. It can meet not only the requirements of sewage treatment projects, but also those of the pile foundation construction of railways and highways.
