Power Tong

DESCRIPTION:
Hydraulic power tong is a workover tool that utilizes the power of the drilling rig to
remove the workover tool. The advantages are obvious and easy to use.
Drilling process in the operation of the largest workers, the most heavy workload is
on, unloading pipe fittings and drill thread, in the past has been with a pipe clamp or
chain clamp, not only labor-intensive, and dangerous. Hydraulic power clamp is the
use of oil rig power operation of the mechanical, unloading deduction tool, can
greatly reduce the labor intensity of the workers to avoid or reduce the occurrence of
injury accidents. At the same time, hydraulic power tongs to strengthen the pipe, drill
wire twist torque, reduce the pipe, drilling tool trip accident occurred. The working
principle of the hydraulic power clamp is to pass the power of the drilling rig to the
hydraulic power clamp hydraulic motor by the stroke reducer, and then by two or one
deceleration, the jaw opening gear rotation, resulting in two high and low speed, Pipe
tool (drill) rotation. When the opening gear rotates, the plate frame does not rotate
under the braking action of the brake hammer, so that there is a relative movement
between the opening gear and the palmar plate. In this way, the two rollers of the

palmar plate will climb on the slope plate and force the clamp on the hips board to
move toward the center of the pipe (drill) until it is clenched with the tool and then
with the opening gear Together drive the pipe (drill) to rotate.

The machine is a combination of master and backup tong, by operating the
multiple valve lever, which can realize the tongs respectively clamping or
loosen .
Equipped with extend leading bar and gantry back-up bar, can realize the
tongs clamping concurrently,facilitate for the sensor installation, to ensure no
twisting while processing .Ensure the torque device performs accurately.
Back-up tong with double oil cylinder lever clamping structure, may realize
tong head clamping pipe surrounded.
Equipped with self locking door device is to protect the safety of the operators.
The torque automatic control system is optional , the effect would be better if
installed .
