Major features:
Major parts of the rig adopt mechanical transmission mode, of which the maintenance and control is simple and the cost performance is high.
Drawworks is a seal type chain transmission drawworks which equips auxiliary drive device for mast lifting and emergency lifting. It adopts integral chain box paralleling, of which the operation and maintenance is simple and dependable and the failure rate is low.
This rig is equipped with an integral driller's cabin, in which a driller can finish major operations and controls. The driller cabin is located on DW fixation water tank, so effect caused by drill floor vibration on instruments and control elements in it can be reduced.
Overall layout of the rig is reasonable, while its modularization can meet the requirements of integrally lifting, train and truck transportation.
