| ┠ ZJ30/1700DBS train type horizontally-moving Cryogenic rig ┨ |
Major features:
The horizontal-translating mode is railway moved type; all equipments are installed on a base which is laid on steel track, moved integrally through hydraulic cylinders for the requirements of cluster well drilling.
Suitable for the ambient temperature scope -45 ℃— 40 ℃ .
The transportation dimension of each component should be not higher than 12m × 3.2m × 3.2m ， and the weight of each module should not be higher than 40T.
There is a 6.3/0.4KV industrial substation equipped for the power system, so there is power selection of industrial grid and diesel generator sets .
