850HP Truck-Mounted Rigs

850HP truck-mounted drilling rig is researched and developed by ZYT Petroleum Equipment Co., Ltd independently. It is the max grade self-propelled drilling rig in China.
With the adoption of numbers of patented technology, the max static load of 850HP drill rigs is 2250kN. Its reliable double engine compound power system can drive operating systems or walking system by single or double engine drive operating system. Its chassis adopts 14 x 10 (or 14 x 12) drive.
The weight of whole truck-mounted rigs is distributed rationally and its performance is reliable.


1. Mature double engines compound transmission structure
2. The main brake of winch adopts hydraulic disc brake system. The auxiliary brake adopts Eaton pneumatic water-cooled disc auxiliary brake.
3. Mast, frame and winch of truck-mounted drilling rig adopts the finite element analysis and design to reduce the weight of the rig.
4. The Chassis of 850HP drill rigs adopts 14 x 10 (or 14 x 12) drive and has a good cross-country ability;
5. Parallelogram substructure has stable structure and is easy to install.
