Switched Magnetism Reluctance Double Power Workover Rig

Double power workover rig mainly consists of homemade special Chassis for workover rig, Diesel engine power unit, Electric power unit which is consists of Switched magnetism reluctance motor and Transfer case, Angle gear box, Drawworks, Mast assembly, Hydraulic and Pneumatic system, Power connection box, CC control cabinet, Electric air compressor, Electric hydraulic pump station, etc.

Diesel engine power is used for the heavy-duty workover job of workover rig such as running and jam release etc; Switched reluctance motor power is used for the normal trip up and down operation.
