ZJ30DBST,3000m oil drilling,750HP drilling rig

Major features:

It is convenient to install and fast to transport as i ts power system, transmission system, control system, lifting system and rotation system etc are centralized on special semi-trailer chassis. RT and drawworks adopt reliable and proven mechanical transmission which is easy to maintain.

Optimized gear paralleling transmission box can realize separate running or paralleling running of two engines; RT climbing chain box is driven through transmission shaft of paralleling transmission box, thus the transmission system and installation is simplified, transmission is reliable.
