TQ series of casing tongs are widely used for making-up or breaking-out of casings
or pipes. The casing tong features high-efficiency, safety, reliability, labor-saving,
and can ensure connection quality. Tong head is designed as open and is fitted with
two jaws which can ensure reliable gripping. Air type clutch is utilized as gearshifting
mechanism, so it is possible to change gear under running. The series of casing
tongs can be configured with torque device to perform computer monitoring and managing
on pressure, torque and rounds. The casing tong has been granted with National Invention
