JZF-D Reverse Circulation Drilling Rig Features:
1. The steel wire rubber track chassis is adopted to reduce the walking noise of the vehicle and not hurt
the road when walking on urban roads.
2. The crawler chassis is equipped with hydraulic outriggers to facilitate the leveling of the rig.
3. The walking chassis is equipped with an electric start diesel engine, which reduces the labor intensity
of the operator, especially in cold seasons.
