1. Building and steel structure fields
- Steel structure building installation
- In steel structure buildings, high-strength bolt connections are a key part. For example, in the construction of large factories, bridges, high-rise steel structures, etc., the initial tightening and final tightening of large hexagonal high-strength bolts (such as M16, M20, M22, M24, M27, M30 and other specifications) require strict control of torque. High-torque electric wrenches can meet the higher torque requirements when tightening high-strength bolts, ensure that the steel structure joints are firmly and reliably connected, and ensure the stability and safety of the entire structure.
- Building curtain wall installation
- The fixing of building curtain walls requires bolt connection, and there are certain requirements for the tightening torque of the bolts. High-torque electric wrenches can be used to accurately apply torque to ensure the installation quality of the curtain wall and prevent safety hazards such as curtain wall falling off due to loose bolts or improper tightening.
2. Industrial Manufacturing
- Automobile Manufacturing
- On the automobile production line, the assembly of some large parts, such as the connection between the engine and the frame, the assembly of automobile chassis parts, etc., requires the use of high-torque electric wrenches to ensure that the bolts reach the specified torque value. This helps to improve the overall safety and reliability of the car and avoid failures due to loose bolts during driving.
- Mechanical Manufacturing and Equipment Assembly
- In the manufacturing process of large mechanical equipment, such as heavy machine tools, generator sets, compressors, etc., many key parts of the bolts require higher torque for tightening. High-torque electric wrenches can accurately control the torque, ensure the mechanical performance and stability of the equipment, and reduce the vibration and noise during the operation of the equipment.
3. Energy Industry
- Wind Power Equipment Installation and Maintenance
- The tower, blades, hub and other components of the wind turbine are connected by bolts and are in a high-altitude, high-stress environment. High-torque electric wrenches can ensure that these bolts reach precise torque during installation, ensuring that wind power equipment can operate safely and stably under harsh conditions such as strong winds. During equipment maintenance, bolts can also be accurately removed and reinstalled.
- Oil and gas extraction and transportation
- On oil drilling platforms, the connecting bolts of various equipment and pipelines need to withstand high pressure and high stress. High-torque electric wrenches can be used to tighten bolts in wellhead equipment, oil pipeline flange connections and other parts to prevent safety accidents such as leakage. In the construction and maintenance of natural gas pipelines, it can also ensure the sealing and safety of pipeline connections.
IV. Rail transit
- Railway vehicle manufacturing and maintenance
- In the manufacturing process of train carriages, such as the connection between the bogie and the car body, the installation of the wheels and other parts, high-torque electric wrenches are required to ensure that the tightening torque of the bolts meets the standards. In the repair and maintenance of railway vehicles, it is also used to remove and re-tighten bolts to ensure the safety of train operation.
- Rail transit infrastructure construction
- In the process of laying rails, some special parts of the bolt connection (such as the connection between the fishplate and the rail) need to be tightened with a high-torque electric wrench to ensure that the rail connection is firm and the train runs smoothly and safely.
