Hydraulic Power Tong
DDT100: 100 kN·m torque, single torque cylinder, suitable for routine operations on small- to medium-diameter pipes.
DDT150: 150 kN·m torque, dual torque cylinders + 25 MPa high pressure, delivering greater torque for the same pipe diameter.
DDT250 Electric Version: Flagship model for large diameters, 250 kN·m torque, three-jaw chuck, compatible with 100–254 mm large-diameter drilling tools.
DDT250 Diesel Version: Designed specifically for off-grid job sites, diesel engine-driven, with all other specifications identical to the electric version.

Description
The DDT100 hydraulic makeup and breakout tong mainly consists of the following components: a backup tong composed of two clamping cylinders, a power tong composed of two clamping cylinders and one torque cylinder, and a hydraulic system including an electric motor, high-pressure oil pump, oil pipes and quick connectors. It is applied to rapid makeup and breakout of drill pipes for trenchless horizontal directional drilling.
The DDT150 hydraulic makeup and breakout tong mainly consists of the following components: a backup tong composed of two clamping cylinders, a power tong composed of two clamping cylinders and two torque cylinders, and a hydraulic system including an electric motor (or small diesel engine), pump, oil pipes and quick connectors. It is applied to rapid makeup and breakout of drill pipes for trenchless horizontal directional drilling.
