Norbar Case Study

Byrnecut

Overview

Multiple businesses (powertrain components & Byrnecut to name a few) from across the country have engaged Norbar to produce a solution to bolting issues encountered when fastening breakpacks on MT6020 articulated dump trucks.

Issues encountered are as follows:

  • Lack of a reaction surface – due to space constraints coupled with protection required to avoid damaging the drive axle.
  • Labour intensive – historically, the common method for torquing break pack bolts was hand torque wrench, which is slow and requires substantial amounts of manual handling.

The previous method used by the client:

The break packs on the Atlas Copco MT6020 dump truck are quite problematic when it come to the application of torque to the M24 cap head bolts that hold the brake assembly together.

Although the required torque is low at 1100nm the customer wanted to get away from the use of hand torque wrenches and the associated manual handling issues they present. However, due to the lack of a reaction point we had to get creative.

Products recommended by Norbar:

SPL833 & SPL838
