Posted By Rob Shrimpton Could anyone advise on one aspect of the use of extension forks on counterbalance lift trucks? Namely, are there regulations regarding fixing the sleeves to the tines using chains, pins, etc?

Posted By Robert. Depends on the truck SWL and centre of gravity. Some trucks have lugs fitted to the lower rear angled part of the tigns so that extension forks can be fitted. The extension forks slide on and are retained on the lugs. I wouldn't trust chains. I would only use pins if they were an intended part of a RT intended lifting. Hope this helps

Posted By Innes Gray The maker of these things have various ways of fixing, to many to list but the main thing is that they all lock the extension sleeve so that they should not slip off the forks Note: You also need to have the safe working load of forklift amended to read SWL derated to XXXKG at xxMM when fork extension sleeves fitted. I also have this SWL marked on the extension sleeves. SWL xxxKG at xxMMwhen fitted to XXXX Forklift

Posted By Joe Quinn Another consideration in using extensions is that the centre of gravity could conceiveable be moved forward which would could result in the FLT tipping forward.

Posted By Alistair Reid BS IS013284:2003 Fork Lift Trucks - "Fork Arm Extensions and Telescopic Fork Arms - Technical Characteristics and Strength Requirements. Key Changes are:- * Minimum blade length for any fork arm to which an extension may be fitted is 750mm * Maximum allowable extension length is 40% of the parent fork arm blade Examples: Maximum fork arm extension length on a fork arm with 1000mm blade is 1400mm Maximum fork arm extension length on a fork arm with 1255mm blade is 2134mm Maximum fork arm extension length on a fork arm with 1800mm blade is 2520mm The following information must be supplied with each set of new fork arms: * Mounting instructions * Capacity rating and limitations of use * Periodic examination for wear or damage The following information is to be marked in a durable and legible manner on each set of fork arm extensions: * Manufacturers name * Serial number and year of manufacture * The rated capacity and load centre distance for the fork arm extension * The required blade cross section and minimum blade length for the parent are

Posted By John A Wright Alistair, thanks for this information which I will use now to enforce ID labelling and proper use of extensions, but can you check example no. 2 where you say: "Maximum fork arm extension length on a fork arm with 1255mm blade is 2134mm". The difference is 879 which exceeds the 40% rule. Were you referring to a fork arm of 1525mm? John W
