Product feature and application
Structural features:
High-efficiency pneumatic motor: The core power of 42mm High-Speed Air Impact Wrench comes from its high-efficiency pneumatic motor. When compressed air enters the tool, it drives the motor's rotor to rotate at high speed. It delivers greater power per unit of air consumption to meet the requirements of 'high speed' and 'high torque', while achieving the goal of 'low air consumption'.
Compact Structure and Pitch Circle Diameter: As a tool designed for M32-M42 bolts, its structural design (such as the pitch circle diameter) fully takes into account the operating space around large bolts, striving for a compact structure while ensuring performance.
Safe and reliable: Powered by compressed air, it has the characteristics of safety and explosion-proof.
Wide applicability: The 42mm High-Speed Air Impact Wrench is suitable for bolts ranging from 32 to 42mm, covering common specifications
Heavy Industry Quality: Heavy industrial-grade manufacturing, sturdy and durable, with quality assurance.
Application fields:
Automobile Manufacturing and Maintenance: Suitable for tightening and loosening various bolts and nuts on automobile production lines, such as engine assembly and chassis assembly. It can also be used for related operations when vehicle maintenance shops perform vehicle maintenance and repair.
Tractor Manufacturing and Maintenance: In the production process of tractors, it is used for tightening and disassembling bolt connections of key components, and can also efficiently complete related work in the maintenance.
Locomotive and Rolling Stock Manufacturing and Maintenance: Can be used for the assembly of locomotives and rolling stock, as well as daily maintenance, to ensure that all components of the vehicle are securely connected.
Shipbuilding and Repair: A large number of bolted connections on ships require reliable tightening and loosening tools. The 42mm High-Speed Air Impact Wrench can meet this need and is suitable for ship construction, repair, and maintenance.
Bridge Engineering: In bridge construction, used for tightening and removing bolts that connect bridge components, ensuring the stability and safety of the bridge structure.
Construction Engineering: In construction scenarios such as steel structure installation and fixing of large equipment foundations, bolts can be efficiently installed and removed.
Production details
High-Speed Pneumatic Motor Technology: The built-in pneumatic motor features an optimized blade layout and airway design, which can efficiently convert compressed air into mechanical energy upon input. This enables a no-load speed of 3100 revolutions per minute, providing strong power for the rapid tightening and loosening of bolts.
Heat Dissipation and Lightweight Technology: Under the premise of ensuring structural strength, a lightweight design concept is adopted to control the overall weight at 17.5kg. When compressed air is exhausted, it can simultaneously blow away 40% of the heat, preventing overheating from affecting the performance and service life of the air impact wrench.

FAQ
Q: What are the common faults of the 42mm High-Speed Air Impact Wrench and their handling methods?
A:
|
Fault |
Reason |
Exclusion method |
|
The machine does not rotate or operates abnormally |
The rotor end face is jammed against the front and rear cover planes. 3. The parts are not clean or the lubricating oil viscosity is too high. |
1. Adjust the gap between the rotor and the front and rear covers. 2. Sharpen or replace the new slide plates to ensure they move flexibly within the rotor slots. |
|
Torque drop |
1. The rotational speed is abnormal. |
1. Adjust the engine. |
|
Increased air consumption |
1. The compressed air pipeline and all connection points are leaking air. |
1. Inspect the pipeline and all connection points to eliminate gas leakage. |
Q: What are the precautions for using the 42mm High-Speed Air Impact Wrench?
A: 1.Pre-use inspection: Before use, an inspection must be conducted to ensure that the equipment has no missing parts or damaged areas. If any issues are found, they should be repaired promptly. Without the permission of the relevant person in charge, no one is allowed to start or supply air to the equipment.
2.Air Source and Connections: The rubber hose on the air supply line should be intact, with secure and airtight connections. Use intake hoses of the specified inner diameter and avoid excessive extension; each 10m extension of the intake hose results in a 0.1MPa pressure drop. Ensure that the compressed air entering the wrench's pneumatic motor is clean, dry air with a maximum pressure of 6.0bar. It is recommended to install an emergency shut-off valve in the air supply line.
3.Operating Specifications: The sleeve must fully enclose the nut or screw slot before pressing the switch. Maintain a balanced and stable body posture during operation. Do not insert fingers or other objects into the working air ratchet wrench. Stay focused at all times to ensure no one is nearby and there are no obstacles around.
4.Torque and Pressure Control: Adjust the appropriate torque according to the bolt specifications and strength. The working pressure should be between 0.5-0.63 MPa. Excessively high pressure will cause tool wear to occur too quickly, while excessively low pressure will prevent the tool from performing optimally.
5.Lubrication and Maintenance: For machine lubrication, the prime mover uses HJ-10 (GB443-84) machine oil. Bearings, gears, and impact mechanisms are selected with ZG-2 (GB491-87) calcium-based grease. If the pipeline is not equipped with an oil mist lubricator, an appropriate amount of lubricating oil should be injected at the joint before each start-up.
6.Avoiding overheating and fault handling: When using the air impact wrench for a long time continuously, pay attention to its temperature to prevent overheating, and stop the machine timely for cooling. If secondary impact is detected during use, stop the machine immediately for inspection. Disassembly is prohibited in unclean areas, and it should be sent to the repair department for maintenance in a timely manner.
