Investing in a hydraulic torque wrench is a significant capital decision. To maximize return on investment and ensure safe, reliable bolting operations, you need the right tool, proper operation techniques, and a disciplined maintenance regimen. The MXTA Series Dual-Drive Hydraulic Torque Wrench is designed to excel in all three areas.
Selecting the correct hydraulic torque wrench is essential for ensuring accurate and safe bolting operations. Using the wrong tool can result in over or under-tightening, leading to equipment failure, costly downtime, or safety risks.
1. Torque Output Requirements
Identify both the minimum and maximum torque values needed for your operations. The MXTA Series offers models from 112 N.m to 72,000 N.m, ensuring you never need to switch tool families for different jobs. Choose a model whose operational range comfortably covers your requirements—picking a model rated to the high end avoids using extenders that reduce accuracy.
2. Bolt Size and Accessibility
First confirm the size of the required bolt and the strength grade. Then consider physical space around the bolted joint. The MXTA Series offers compact models like the 07 MXTA (1.8 kg) for tight spaces, and larger models like the 50 MXTA (85 kg) for heavy-duty flange bolting.
3. Working Environment
Extreme temperatures, humidity, chemical exposure, and flammable gases all influence tool selection. The MXTA Series' aluminum-titanium alloy body provides corrosion resistance and durability across diverse environments.
4. Drive Size Compatibility
The MXTA Series offers 3/4", 1", 1-1/2", and 2-1/2" drive shafts to accommodate standard industrial sockets. Ensure your square drive sockets are in good condition—any worn sockets should never be used as they won't securely hold the nut.
Hydraulic torque wrenches operate at high pressures, with most operating at 10,000 psi and producing torque outputs of over 50,000 ft./lbs. Proper operation is critical for safety and accuracy.
Visual Inspection: Examine all components before use and ensure all parts are firmly secure. Inspect for tool damage, cracks, or wear.
Run-In Procedure: Run the tool at full scale at least 3 times before starting the job to ensure all moving parts are functioning correctly.
Pressure-to-Torque Chart: Have the correct chart for your chosen tool at hand. The MXTA Series provides comprehensive comparison tables for both N.m and ft.lbs across all pressure settings.
Hydraulic Fittings: Ensure connections are fully engaged on the hoses to the tool and pump.
Apply torque in a slow, methodical manner—fast or jerky movements can cause the applied torque to increase or decrease more than desired and possibly damage the tool.
Keep hands clear of the wrench's reaction arm and all pinch points.
Never exceed the maximum working pressure of the pump or tool.
Always use a properly fitted and secured reaction arm.
Fully turn off the pump on the pendant switch when removing the tool from the bolt.
Store torque wrenches in a clean, dry, and protected area.
Avoid marking, etching, or placing labels on the tools while not in use.
With correct care, a hydraulic torque wrench will provide accurate measurements for many years, saving on capital expenditure.
Calibration: Operate the torque wrench within the manufacturer's advised calibration range, or following a certain number of cycles.
Lubrication: Lubricate in line with equipment usage to reduce friction.
Hose Care: Never expose hydraulic hose assemblies to high temperatures, and keep them away from sharp edges and chemicals. Never use a damaged hydraulic hose assembly—replace it immediately.
Component Inspection: Remove damaged equipment from service.
Never use hydraulic torque wrenches without a hydraulic gauge to indicate the working pressure.
Avoid excessive heat, flame, moving machine parts, sharp edges, and chemicals.
Never exceed the tool's maximum rated pressure/torque.
The MXTA Series is designed with serviceability in mind:
New-type anti-loose joints ensure smooth oil flow and consistent performance
Aluminum-titanium alloy construction resists corrosion and wear
Trigger-type lock enables quick reaction arm positioning
Dual-drive design reduces cycle time and component wear
Selecting, operating, and maintaining a hydraulic torque wrench doesn't have to be complicated. By following these guidelines and choosing a quality tool like the MXTA Series, you ensure safe, accurate, and reliable bolting operations for years to come. The MXTA Series combines industry-leading torque range, precision engineering, and rugged durability—making it the smart choice for professionals who demand the best.
Identify your required torque range and largest bolt size. The MXTA Series offers 11 models from 112 N.m to 72,000 N.m, covering bolt specifications from M14 to M125. Choose a model whose operational range comfortably covers your minimum and maximum torque values.
Calibrate following the manufacturer's advised schedule or after a certain number of cycles. Regular calibration ensures accuracy and extends tool life.
Always inspect components before use, never exceed maximum working pressure, keep hands clear of the reaction arm, wear appropriate PPE, and fully shut down the pump before removing the tool.
Yes. The MXTA Series features square drive outputs in 3/4", 1", 1-1/2", and 2-1/2" sizes, accommodating standard impact sockets. Ensure sockets are in good condition and the correct size.
Store in a clean, dry, and protected area. Avoid marking or placing labels on the tools. Keep all components away from excessive heat, sharp edges, and chemicals.
This is the last one.
