550HP Truck-Mounted Rigs

550HP mobile drilling rigs are 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 truck mounted rigs is 1350kN. With the adoption of numbers of new patented technology, our 550HP rig adopts CAT engine and Allison M6620AR gearbox as its driving force. Its chassis adopts 10 x 8 drive. Its overweight distributes rationally and its performance is reliable.
Mobile 550HP drilling rigs are widely used for overhaul of deep oil fields, workover, oil testing, salvage and pump inspection operation.


1. The 550HP truck mounted rigs adopt 10×8 self-propelled chassis.
2. The main brake of winch adopts hydraulic disc brake system and its auxiliary brake adopts Eaton pneumatic water-cooled disc auxiliary brake.
3. Finite element analysis and design of mobile drilling rigs is adopted on Mast, Frame and drawworks to reduce the weight of the rig.
4. The China truck mounted rigs adopt 5+5R anti-reverse rotary table transmission device.
5. Parallelogram substructure has stable structure and is easy to install.
