• The MXTA Series Square Drive Hydraulic Torque Wrench is designed for controlled tightening and loosening of industrial bolted connections. Its square drive transmits torque through a compatible impact socket, allowing the tool to accommodate different bolt and nut sizes by changing sockets.

• Powered by an external hydraulic pump, the wrench converts hydraulic pressure into rotational torque through an internal piston and ratchet mechanism. Repeated hydraulic cycles progressively rotate the fastener. The required tightening torque is set by adjusting the pump pressure according to the pressure–torque chart for the specific wrench model.

• A reaction arm transfers the counteracting force to a suitable, stable reaction point during operation. Correct positioning of the reaction arm and full socket engagement are essential for reliable torque application.

• The MXTA series is suitable for bolting work on flanges, pressure vessels, pipelines, steel structures, mining equipment and heavy machinery. Tool selection should consider the required torque, square drive size, socket dimensions, available working space and reaction point arrangement.

Technical Characteristics

• Hydraulic operation for high-torque bolting applications.
• Square drive output for use with compatible impact sockets.
• Ratchet mechanism for incremental fastener rotation.
• Pressure-based torque setting using a model-specific pressure–torque chart.
• Reaction arm for supporting the counteracting load.
• Suitable for tightening and loosening with the appropriate tool configuration.

System Requirements

• The wrench must be used with a compatible hydraulic torque wrench pump, correctly rated hoses and couplings, and a suitable impact socket. Torque range, maximum working pressure, square drive size, accuracy, dimensions and weight are specified in the technical data sheet for each MXTA model.
