Questions buyers ask
- What is Hande workover-rig electric drive?
- It is the electric drive and control system of the workover rig, listed as its own business area. The catalog page is a rating table rather than a separate feature essay.
- What does the table list?
- Three columns of winch inverters at 900 kW, 1,000 kW, and 1,200 kW, mud-pump inverters, 500 kW rotary-table inverters, rectifiers, and brake units, plus MCC feeder, soft-start circuits, cooling, and the driller's console.
- Do the columns name a rig class?
- The printed table does not put a rig-class header on the three columns. The figures below follow that layout. Mud-pump inverter duty is also on mud pump control. The drilling-rig chain is drilling rig electric drive.
