4000m Mechanical rig
ZJ40/ 2250L Drilling module |
Main features of drilling rig：
DW is seal type chain drive drawworks with 4 forward+ 2 reverse gears (or 6 forward+ 2 reverse gears); there is auxiliary drive device used for lifting derrick and emergency lifting.
Integrated driller's cabin can accomplish most rig operation and control.
Cardan shaft is used for connection between all parts of transmission system, making assembly and disassembly easy.
The rig can form a complete set in wider range with higher mechanization and strong adaptability.
