The DXJ250 electric workover unit is the latest self-developed truck-mounted work-over equipment of our company. It is an environmentally friendly machine, which can save energy, reducing the operating cost, emissions and noise pollution.

Technical Characteristic

1. Power source: network electronic + energy storage system
2. Electric workover machine adopts self-made chassis, which has higher security and stronger bearing capacity. The mast can be 17m, 21m, 25m according to requirements.
3. Main motor adopts AC variable speed control, which can realize step less speed regulation.
4. Auto recycling of the power feedback from braking and lowering down to save energy.
5. The energy storage system and wellhead transformer can supply the power together, which can meet the power requirement of work over operation, and there is no need to equip transformer substation, thus reduces the security risks and improves the operational efficiency.
6. The output power control function to wellhead transformer can protect the wellhead transformer.
