Hydraulic power tongs are specially used to unscrew drill rods during drilling operations of lifting and lowering loads. They can match with all kinds of core drilling equipment including vertical shaft, full hydraulic and top-drive core drilling rigs and are suitable for the screwing and unscrewing of various specifications of geological drill rods, wire line drill rods, water well drill rods and casings.Features
Portable machine: Hydraulic power tong, with compact structure, is composed of lead tong and back-up tong.
Simple operation: Reversing valves can make lead tong and back-up tong clamp and loosen synchronously.
Two gears setting: High-gear high speed unscrewing and low-gear large torque unscrewing can be achieved.
Reliable performance: The performance is tested on many 2000m deep geological drilling sites.
Ease of connection: Hydraulic power tongs can be connected with all geological machines and they don't affect each other.Parameters
