This 1-inch drive heavy-duty twin hammer impact wrench (YD91-013) adopts a twin hammer structure, which can provide strong and stable torque output, making it easy to handle the disassembly and assembly of large-sized bolts. It is equipped with a 1-inch square drive (sokce 1"), which is convenient to match with various sockets.
The body is equipped with a power switch for convenient control of the device's start and stop, and an F-R switch for flexible switching between bolt tightening and loosening modes. At the same time, the equipped handle enhances the grip stability and comfort during operation, which can effectively reduce hand fatigue even during long-term operation. The air inlet is used to connect the air source to provide power for the wrench. The whole is made of solid metal material, which has excellent durability and can adapt to harsh working environments.
- Automotive Maintenance Field: During the maintenance of large trucks, engineering vehicles, etc., it is used to disassemble and assemble large-torque bolts in parts such as tires and drive shafts.
- Engineering Machinery Industry: For the key components of engineering machinery such as excavators and cranes, such as crawler belts and chassis connecting bolts, it is used for installation or disassembly.
- Steel Structure Construction: When constructing steel structure buildings such as factories and bridges, it is used to fasten or disassemble large steel structure connecting bolts.
- Mine Equipment Maintenance: For the daily maintenance and overhaul of mine mining equipment, such as crushers and mine transportation equipment, when large-sized bolts are involved, this wrench can efficiently complete the work.
A: It is generally recommended that the air source pressure be between 6 - 8 bar to ensure that the wrench can output sufficient torque and work normally and efficiently.
A: After use, clean the dust and oil on the wrench surface in time; regularly check the air inlet tightness and the operation flexibility of each switch; and according to the frequency of use, regularly add an appropriate amount of special lubricating oil for pneumatic tools to the internal components to prolong the service life of the wrench.
A: It may be that the air source pressure is insufficient and cannot provide sufficient power for the wrench; it may also be that internal components such as the twin hammer are worn, resulting in reduced torque transmission efficiency; in addition, blockage of the air inlet or aging and air leakage of the air hose will also affect the torque output of the wrench.
