Mechanical drilling rigs (including both belt-driven and chain-driven types) come in various specifications such as ZJ30/1700J, ZJ40/2250J, ZJ50/3150J, ZJ70/4500J, as well as ZJ30/1700L, ZJ40/2250L, ZJ50/3150L, and ZJ70/4500L.

Technical Features

The driving methods such as "diesel engine + hydraulic torque converter (or coupling forward gearbox) + chain parallel gearbox", "diesel engine + reducer + narrow V-belt parallel gearbox", or "diesel engine + ALLISON gearbox + gearbox parallel gearbox" are adopted, which have high power utilization rates and meet the needs of different drilling conditions;

The winch is available in both internal and external variable speed options. The main brake utilizes band brakes or hydraulic disc brakes, while the auxiliary brake employs electromagnetic eddy current brakes. The pneumatic remote control for winch shifting is easy to operate;

Equipped with sand reel drum, mechanical friction cathead, and rotary table drive device. Easy to disassemble and assemble;

The main engine of the drilling rig for levels above 4000 meters is arranged in a "front high, rear low" manner, with the power and transmission systems installed at a low position; it meets the requirements for well site migration during cluster drilling; and intelligent driller control of the drilling rig is achieved through PLC.
