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.
