Backing spanners help improve safety and efficiency

Simple, easily applied backing spanners can be used to enhance safety and precision of torque wrench bolting operations.

Backing spanners with screw adjustment are easily deployed as a compact alternative to flogging spanners to help stop nuts slipping on applications such as flanges, machinery joints and mobile plant and vehicle maintenance in resources and energy plants, oil and gas sites and construction, manufacturing, fabrication and maintenance operations.

A world leader in professional bolting technologies, Enerpac says backing spanners extend the safety and durability of torque wrenches such as its globally proven ranges, including the latest S series square drive and W series low profile hexagon cassette series, which themselves have new features enhancing their safety, durability and ease of use.

“Durable steel torque wrenches are themselves a giant step forward in non-impact bolting technologies, giving immense power, precision and repeatability of performance to ensure joint security,” says Enerpac national bolting manager Pat Molloy.

“Backing spanners such as those available to complement Enerpac products help eliminate the need for potentially hazardous manual use of flogging spanners, which can spit out under load and also jam nuts in place, which then requires a hammer to free them.

“Safety and ergonomics are further improved by the hands-free operation of backing spanners that clamp magnetically into place, adhering securely onto the nut and flange.”

“Backing spanners can complement torque wrenches by taking the safety process a step even further in numerous applications.”

Every Enerpac torque wrench comes with a certificate of performance (calibration), which is critical to safety and a prerequisite to traceability of bolting performance in tasks such as fabrication and maintenance.

Hydraulic torque wrench verification services offered by accredited Enerpac distributors also help safeguard against torque output changes over time as materials wear and age.
