Product features:
·Rational whole structure, high containerization, effectively reduce the frequency of transport
·Use heavy-load 4-axle chassis. Adopt hydraulic power steering. The workover rig has high trafficability and high cross-country performance.
·The emission meets China 4 or China 5 standard. It is environmental friendly.
·The derrick has front open and is a binodal suit FC mast-type derrick. It raises, stretches out and draws back by hydraulic pressure. Air cylinder lock is adopted.
·Driller operation room is equipped. All operations can be made in the operation room. Heating system is equipped. Air-conditioner can be installed.
·The master rotor brake adopts link mechanism remote control in the driller operation room. The hydraulic auxiliary unit is equipped to reduce the work intensity of driller.
·The winch input adopts gear drive. It has long service life and daily operation can be reduced.
·Adopt machine-power- hydraulic-gas integration technology to realize machine automation. Thus, the well repair efficiency and safety can be greatly enhanced, and workers’ work intensity can be reduced.
·Uphold “people first” design concept. Intensify safety protection and detection measures.
