Series of Drill Pipe Power Tongs TQ340-35ZQ203-1001/ZQ162-50/ZQ203-125/ZQ203-125/TQ178-16

Short Description:

ZQ Series Hydraulic Power Tongs

Engineered for high-torque pipe handling, the ZQ Series delivers reliable performance across a wide range of pipe sizes, from 2⅜” to 8″. With maximum torque ratings up to 125 kN·m and robust hydraulic systems rated at 12–20 MPa, these tongs ensure consistent power and control for both routine and heavy-duty operations. Built for durability, they feature low-speed, high-torque performance, long shifting strokes, and optional tong head lift for enhanced operational flexibility. The compact yet heavy-duty design minimizes downtime, making them ideal for demanding oilfield and drilling applications.

TQ Series Hydraulic Power Tongs

Designed for versatile, mid-range pipe handling, the TQ Series offers precise torque control for pipes from 4″ to 13⅜”. With multi-speed gear options (high/mid/low) and torque ratings up to 40 kN·m, these tongs adapt seamlessly to various pipe makeup and breakout tasks. Operating at a system pressure of 18 MPa and compatible with 110–160 L/min flow rates, they deliver reliable speed and power across all gear ranges. Their lightweight, compact construction ensures easy installation and maneuverability, making them a practical choice for both onshore and offshore drilling operations.
