Portable Large Torque Handheld Hydraulic Tools , 9.1Kg Hyd Torque Wrench

Portable Large Torque Handheld Hydraulic Tools , 9.1Kg Hyd Torque Wrench

Hydraulic wrench has two series of driving hydraulic torque wrench and hollow hydraulic spanner.

The driving hydraulic torque wrench is used as the universal hydraulic spanner with the application of the specification sleeve.

Standard quadrangular drive shaft, with different specifications of sleeves, suitable for a variety of

occasions, the maximum use of high-strength light metal, integrated molding power head, improve overall

strength and life; large torque / weight ratio, double-acting, high-speed, large rotation angle, high

efficiency, 360 degrees * 360 degrees rotary hose joint so that in a narrow space Easy to use, there will

never be any mechanism stuck, torque repetition accuracy as high as 65 With the wide use of high

strength bolts above grade 8.8, the hydraulic wrench is necessary to meet the design requirements for

the use of connection and preloading.

SHTW hydraulic wrench has compact structure, small volume, light weight and large output torque.

It is a powerful tool for nut disassembly and bolt pre-tightening. Torque control in this 3% range can meet

the requirements of pre tightening high precision torsion value. One-way ratchet pawl mechanism

prevents the drive shaft from reversing, ensures reliable operation, adjustable support arm, fully adapted

to different working environment, free from space restrictions, and handy operation.

The standard square drive shaft with different sleeves is suitable for many occasions.

Product Features

1. Compact, uni-body designed to give housing maximum strength with minimum weight. It was made

of durable , high-strength, light weight aircraft alloy.

couplings.

3. With automatic pump, square drive wrench could automatic to tighten or loosen .

4. Accurate anti- reverse pawl improved the preload accuracy, and could be quick released

5. Constant torque output accuracy up-to ±3%

6. High speed, double-acting operation

7. Oxidation treatment provide excllent corrosion protection and durability in harsh enviroment

Machine Parameter

Actual Process Picture

Attention should be paid to the following problems when using

hydraulic torque wrench:

1. If the wrench can't be clamped when taking the wrench, press (RUN, button does not loosen the hand,

while pulling the quick release trigger, then loosen the button, take off the wrench. Do not strike with a

hammer, otherwise it will damage the hydraulic cylinder and piston assembly.

2, if you bring (SET, reset button), press the hydraulic pump before starting (SET, reset button).

3. If there is a whistle during the test run, the pressure should be lowered to the minimum, and the working

cycle should be repeated until the gas is exhausted without whistling.

4. The normal working temperature is 10 - 70 C.
