| ┠ ZJ30/1700DBS helicopter-lifted Cryogenic rig ┨ |
Main features:
The rig is designed into modules, overall layout reasonable and for integral lifting; it is convenient for transportations of railway, land way, waterage and helicopter hoisting etc.
The horizontal-translating mode of the rig is rail moved type; main equipments (mast, substructure and drawworks) 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 18T, optimized strucural design meets helicopter-lift transportation.
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 .
