Worldwide Applications For HoldFast Adjustable Rail Clips

Launching Rockets!

These photographs show a 1700 metre long 'rocket launcher' for the Ministry of Defence. HoldFast had to design this twin track so as to give lateral alignment adjustment of 22mm, but in stepless movements to any part of a millimetre - this was readily achieved.

Also required were double base plates for vertical stepless adjustment, taking into consideration earth curvature; again to an infinite amount.

This lateral and vertical adjustment is necessary at any time due to land settlement, shift, and of course rocket thrust.

Ground Tracks

A Proven 'Track' Record combined with Modern Technology

To offer as near as possible a stress free rail track system Holdfast combine long term expertise with leading edge technical and environmental solutions.

Expertise and Practical Knowledge

The HoldFast philosophy is to work closely with civil enginering consultants and civil contractors to achieve the most cost effective solution to a rail track problem.

To bring succesful results and a comprehensive service to clients means not just understanding theoretical solutions (such as crane track problems) but by balancing practical knowledge gained in the field. Examples such as the cause and effect of deflection; shear forces; rail wear; deterioration of grouts and resilient pads.

Design and Installation

HoldFast advise, with the customers requirements in mind, on the best design and installation procedures such as long life and minimum demands on maintenance. The HoldFast track technology is determined by progressive thinking based on the latest technical advances.

Understanding the Uniqueness of every Project

Whilst being experts in clips and rails HoldFast also apply the principal that it is imperative to understand the machines which run on them and therefore the different types of forces imposed on rail tracks.

For example, often a rail problem most frequently manifests itself with crane operation and the blame put onto the manufacturers for excessive wheel wear, gearbox failure and overheated motors.

More pertinently the issue here is that no two contracts are the same. Therefore the choice of rail track system for a specific job depends on many factors; for example ground conditions, type of machinery, seismic conditions, corrosive and abrasive conditions.
