A new generation of controlled fastening solutions from global professional bolting leader Enerpac is ready for the maintenance season following a series of product innovations relating to workplace efficiency, speed, reliability and safety.
The latest generation of technologies designed to optimise performance and minimise downtime this maintenance season includes the innovative new Electric Torque Wrench (ETW), which records torque readings while being used and displays them on a 7-inch touch screen similar to those used my mobile devices.
Another advance is the X-Editions of Enerpac’s compact and powerful globally proven S square drive and W series low profile hexagon cassettes provide the tools with enhanced new safety, efficiency and ergonomic features.
“Collectively the range of innovations is part of an evolutionary generational change to one of the world’s most widely used ranges of controlled bolting solutions,” says Enerpac National Bolting Manager Mr Andrew Marsh. “What’s equally important to users is that the new product family is all compatible with our widely used existing technology and backed by the level of service and technical support Enerpac users have enjoyed in Australasia for more than 50 years.
“This backing is very important, because even brilliant technology is worse than useless if it breaks down and users can’t get it back into service safely and quickly.
“The technology we are bringing to the maintenance season responds to the major priorities of companies today, which include:
- Safety first, complemented by service backup and traceability of technology manufacture and service to comply with world safety and quality standards.
- An absolute need to ensure reliability and minimise downtime in highly competitive markets, where the tools are used to fabricate structures and to maintain both fixed and mobile plant, including track and wheel vehicles.
- A strong preference by major mining, resources, infrastructure and construction companies to deal with one supplier that can offer diverse ranges of hydraulic, pneumatic and mechanical bolting tools, complemented by outstanding ranges of pumps and ancillaries that can be used to tailor controlled fastening solutions to the needs of particular sites.
Enerpac has responded to the preferences of users of its hydraulic bolting tools with advances such as the latest X-Editions of its S square drive and W series low profile hexagon cassette series, which feature a stronger, more durable and safer connection between tool body and manifold, along with a dual plane swivel manifold that features interlocking arms to increase robustness and safety.
Both the new square and hexagonal drive X-Edition wrenches come standard with tough upgraded safety handles featuring one-piece design with metal inlays for positive location, as well as an optional ergonomic straight handle designed for narrow or confined applications. The use of the handles increases safety and avoid potential pinch point situations for operators.
The hexagonal X-Edition cassette wrenches also feature a top handle mount on cassettes to help operators attain easier handling for narrow access applications while keeping hands away from pinch points. Productivity is enhanced on the square drive X-Edition wrenches by wider reaction arm release levers, making positioning of the reaction arm simpler in gloved hands.
Certificate of Performance
Productivity is also facilitated by engraved tool markings on the wrenches, including direction-of-turn for tightening or loosening with the square drive and low profile hexagon cassette series. The fitment of the optional angle-of-turn indicator on the square drive tools allows for angle of turn or turn of nut method of tightening typically used in construction applications. A CE-ATEX declaration for use in explosive environments is provided with each tool.
Every Enerpac X-Edition torque wrench also now comes with a certificate of calibration, which provides end users with assurance that the tool meets the stated performance expectations.
“Certification is critical to safety and a prerequisite to traceability of bolting performance in tasks such as fabrication and maintenance,” says Mr Marsh.
“Precise results in bolting tasks can be relied upon only if all bolting system components have been properly tested and certificated to ensure that bolting systems deliver the precision and repeatability required for assurances of joint integrity.”
Furthering the safety and user-friendly theme, Enerpac’s UltraSlim torque wrenches – which complement Enerpac’s globally proven W hexagon and S square drive torque wrenches – feature a tapered design, narrow radius and top-mounted handle to help facilitate access to very tight spaces.
The compact, durable and simply maintained UltraSlim torque wrenches are designed for general limited access applications in industries such as construction and infrastructure and particularly for applications in the oil and gas, mining, energy and marine infrastructure sectors including onshore and offshore drilling rigs and blowout preventers.
UltraSlim torque wrenches can easily be mounted over bolts in narrow access applications. In addition to its compact size, UltraSlim wrenches provide superior accuracy with plus or minus three percent across the full stroke.
Electric torque wrenches
In recent years, the need for fast, accurate and traceable fastening solutions has resulted in the advent of increasingly sophisticated controlled bolting tools. These solutions, however, are often complicated to use, making it difficult for the average user to understand them, and requiring a significant investment in training.
Enerpac’s mission with its new ETW series electric torque wrench is to take SMART bolting, and make it simple. This SMART, yet simple new tool is custom-engineered to provide fast, accurate and safe fastening for applications that require speed, precision and traceability.
The new ETW tool is operated with a 7” touch-screen, similar to those used in many popular mobile devices. The touchscreen is housed in an impact and flame resistant control box, which helps simplify and automate complex jobs, including those with torque and angle specifications through the creation of presets. Using the touchscreen, the operator simply inputs the number of fasteners and the desired torque value for each fastening step, followed by the required angle of turn. This sequence may then be saved as an automatic preset for future use.
For simpler jobs, torque values may be input with a digital slider on the touchscreen, or directly into the rear control panel on the wrench. Once the input torque is achieved, the tool stops, and a pass/fail indicator verifies that it is ready to move on to the next fastener. When the job is completed, the fastening record can be viewed on the touchscreen, or exported to a computer via a USB connection on the control box. Key features of the ETW-Series Electric Torque Wrench include:
- The ETW tool gets the job done faster by providing continuous rotation for constant torque output
- Torque and angle function allows input of nominal torque value followed by a specific angle of rotation
- Pass/Fail indicator on back of tool verifies that the fastening has been completed accurately
- Large 7” touchscreen simplifies tool operation
- Control box simplifies complex jobs through the creation of automatic presets
- Controls on back of wrench enable operator to monitor and manage the fastening process without returning to the control box
- Fastening records may be viewed on-screen and transferred through a USB port on the control box
