Bolting System for Railway Switch Track Equipment

Many bolting applications are problematic because there is no suitable reaction point. This can be overcome by using a Reaction Platform System designed to suit specific bolting applications.

The Bolting System for Railway Switch Track Equipment consists of a VC-RAD 14 Electric Torque Tool, Crank Slotted Reaction and Reaction Platform. 

The assembly process involves fitting a metal plate to the concrete sleeper with self cutting bolts (14mm AF Male Hex.) which fit into plastic inserts within the mounting holes.

• The VC-RAD 14 has a 3/4" Square Drive and is capable of 1,350 Nm
   
• The Reaction Platform sits over the sleeper, providing a stable reaction. The platform is tapered in order to follow the profile of the concrete sleeper
   
• The Crank Slotted Reaction sits over the the reaction post on the platform and reacts against it
   
• A 14mm, 3/4" square drive hexagonal socket is designed to match the height of the hexagonal section on the bolt

This system ensures a stable reaction for the safe and correct tightening of the metal plates to the sleepers. It can also be used for un-tightening the bolts.

The principles behind this tooling system can be applied to many other bolting applications across all industries.
