Desert Fast Moving Trailer-Mounted Drilling Rigs
Description:
When the rig is in a short-distance movement, the mast and substructure can be overall moved in standing status, Axle assembly can be rotated by go degrees, to realize longitudinal and lateral movement of the drilling rigs.
The first one of China to fully cover onshore drilling rigs with fire protection system, The first one of China to employ hydraulic quick disassembly structure on the mud pump package fluid end.reducing labor intensity.
The driller' s house is installed with overall positive pressure air conditioning system, therefore H2S and other harmful gases are not permitted into driller’ s house, guaranteeing safety of the driller.
The rig can be moved to another well within 48 hours and 10 km distance.
