    SECTION 1 – HEALTH & SAFETY INSTRUCTIONS 1.1 SAFETY NOTES Hydraulic bolt tensioning tools are very powerful and capable of inducing very high bolt stresses. This equipment will give many years of safe tensioning when used in accordance with these instructions. Anyone using hydraulic bolt tensioning equipment must be properly trained to use the equipment and must take adequate steps to ensure their own safety and the health and safety of others where bolt tensioning operations are being performed.
  • Page 5: European Pressure Equipment Directive

    1.2 EUROPEAN PRESSURE EQUIPMENT DIRECTIVE The Typhoon+ range of hydraulic bolt tensioners are designed to operate at pressures up to 1350 bar with Group 2 liquid (hydraulic oil ISO 32 or ISO 46) with a volume less than 10 litres. This equipment aligns with: •...
  • Page 6: Hoses

    1.4 HOSES Boltight supply flexible hydraulic hoses which have a small plastic core tube surrounded by multiple high tensile steel spiral windings. The outside of the hose is molded with a coloured plastic coating. Most hoses also have a clear plastic cover which provides additional protection against damage when in use. Each hose is identified with a serial number.

    1.5 HYDRAULIC BOLT TENSIONING TOOLS Maximum pressure Do not exceed the maximum working pressure. This can be found etched directly onto the tensioner, on the general assembly drawing for the tensioner or the pressure vs load graph. The bolt being tensioned may have a maximum load less than that generated by the The operator is alerted that tensioner at maximum working pressure.
  • Page 8: Section 2 - Operating Instructions

    SECTION 2 – OPERATING INSTRUCTIONS Introduction A hydraulic bolt tensioner is simply an annular jack with a hollow bore. Much like a jack, a hydraulic pushing force is generated, however instead of lifting a heavy object the force is transferred into stretching a bolt. To allow the transfer of force into the bolt a hydraulic tensioner utilises a threaded puller, bridge and nut rotating socket to effectively transfer and lock in the tensioned load within a joint.
  • Page 9: Main Component Parts

    2.1 MAIN COMPONENT PARTS Hydraulic load cells A multi-stage bolt tensioning tool comprises axially-stacked interlocking load cells (each comprising a body, piston and inner/outer seal), a common central puller (comprising a reaction nut and 1/2” drive socket) and a spring retraction system.
  • Page 10: Tensioning A Bolt

    2.3 TENSIONING A BOLT Step 1 ≥ D Please follow all safety instructions set out in Section 1. Ensure the joint has been assembled using the correct nuts and bolts required for tensioning. To ensure the safe and effective use of the hydraulic bolt tensioner ensure that a minimum of 2 x bolt diameters of bolt length is protruding from the surface of the joint face.
  • Page 11 Step 3 Engage the puller bar with the bolt. A ½” square drive socket is provided - insert into the top of the puller bar so that the tensioner orientation can be maintained whilst the puller bar engages the bolt. Step 4 Continue rotating the puller bar, increasing its engagement with the bolt until the bridge is flush with the application surface.
  • Page 12 Step 5 Once the tensioner is in situ, it should still be possible to rotate the bridge to a suitable angle to access the bolt if required. Step 6 Connect the tensioner to corresponding hydraulic HYDRAULIC HOSE hose and pump unit. Make sure the quick connect coupling is fully engaged.
  • Page 13 TENSIONING A BOLT – HEALTH & SAFETY The bolt tensioning tool is now ready to be pressurised. Before proceeding read the Health & Safety Instructions given in Section 1 of this manual then proceed as follows: — Ensure suitable PPE has been utilised prior to pressurisation. —...

  • Page 15 Step 10 The Tensioner will have retracted upwards as the bolt will have elongated. The tool will need reengaging onto the flange. Using the ½” square drive socket, reengage the puller onto the stud until the tool is flush with the flange. FLUSH NOT FLUSH THEN ONE ADDITIONAL...
  • Page 16 Step 12 Slowly release the hydraulic pressure by opening the pressure release valve on the hydraulic pump’ The spring return system will now fully retract the tensioning tool. The top of the puller bar will be flush with the spring cap at zero stroke. DO NOT disconnect the hose from the tensioner as this will prevent the tool from retracting.

    2.4 DE-TENSIONING A BOLT Step 1 De-tensioning of a bolt follows many of the steps as shown in the previous section. There are however a few key differences in the process which are explained within the following section. ≥ D Follow all safety instructions set out in Section 1 then visually inspect the bolts to be de-tensioned.
  • Page 18 Step 3 Engage the puller bar with the bolt. A ½” square drive socket is provided - insert into the top of the puller bar so that the tensioner orientation can be maintained whilst the puller bar engages the bolt. During the rotation of the puller, ensure that the bolt remains stationary as failure to do so could result in a reduced thread...
  • Page 19 Step 5 Now rotate the Puller ANTI-CLOCKWISE BY HALF A TURN ANTI-CLOCKWISE This is to prevent the Tensioner from locking HALF A TURN onto the stud. This will raise the tensioner slightly so the bridge is no longer flush with the application surface.

  • Page 23: Simultaneous Bolt Tensioning

    2.5 SIMULTANEOUS BOLT TENSIONING Ensure you have read and understood both the bolt tensioning and de-tensioning methods as shown in the previous sections prior to conducting a simultaneous bolt tensioning operation. Simultaneous bolt tensioning improves the speed and efficiency when performing a tensioning operation on a multi stud application.
  • Page 24 Daisy chain arrangement The daisy chain arrangement is an affordable method of connecting multiple tools. It is best for simplicity, as only one type of hose needs to be specified, however with this setup oil must pass through every hydraulic cylinder increasing the resistance for manual piston reset or increasing the time reset takes for auto return tensioners.
  • Page 25: Section 3 - Maintenance & Storage

    SECTION 3 – MAINTENANCE & STORAGE Introduction A hydraulic bolt tensioning tool will provide many years of trouble free service if used, maintained and stored correctly. 3.1 STORAGE Typhoon+ has Boltight’s unique surface finish as standard which provides long lasting protection in harsh and hard working environments. It is recommended that, before storage, the tools should be checked for damage and if OK, lightly oiled.
