1. Trailer-mounted drilling rig with separate main frame
Main series GW-M1000 and ZJ10DBT, ZJ30DBT, AJ40DBT, the rig
consists of front and rear modules mainly during transportation.
The front module includes drill floor and rotary table drive while
the rear module includes drawworks drive, power system, suits for
1) Front level of substructure may be telescoping or semi trailer
mounted while the rear module is semi trailer mounted.
2) Mast is two or three sections telescoping and can be moved with
rig main module or separately.
3) AC VFD motor drive is used for power transmission while diesel
engine compound is optional.
4) Good mobile feature with module design for easy moving and
5) A separate driller cabin is fitted. Operations for air, electric
and hydraulic, drilling data and parameters are all in the cabin.
All operations by driller can be completed in the cabin for better
working conditions and less working strength..
6) According to user’s requirement , auto drilling system and top
drive drilling system can be equipped.
2. Trailer-mounted drilling rig with integral main frame
Model ZJ40/2250DT, ZJ50/3150DT and ZJ7DT trailer mounted drilling
rigs are newly developed in recent years range 4000-7000 meters
drilling depth. Such series rigs are designed for relative flat
desert and Gobi area, which features simple and reliable drive
system, less transportation loads and easy moving.
1) With advanced AC-SCR-DC or AC-VFD-DC electric drive technology
and good drilling performance.
2) Module-type substructure or parallelogram substructure rigged-up
by drawworks power (oil cylinder) and telescoping mast or K-mast
are adopted. Top drive fitting is available;
3) The main frame can be moved integrally or separately, the mast
can be moved as a whole by wheels, and the power unit can be moved
by wheels integrally or separately.
4) Highly modularized, the drilling rig can be moved with fewer
trucks. The trucks used are 1/3 of what we normally use for a
5) Moving time is only 1/4 of what it takes for a normal rig. With
less expense and high efficiency.
6) Top drive can be equipped.
