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.
