Hinged Lightweight Post
The Collis Engineering Lightweight Signal Post is a revolutionary designed post within the United Kingdom rail market.
The lightweight post comes in forms;-
- Straight Post – to replicate a 912mm signal post
- Offset Post – to replicate a 1262mm and 1500mm signal post
Superstructure design calculations and drawings along with Form A and Form B documentation are available as part of our design package. The post has been designed to support any Network Rail approved LED signal head, LED lightweight signal head and any Network Rail approved railway signals or indicators.
The post is fitted with an internal hinge mechanism to facilitate lowering to ground level and maintenance of the signal head. The hinge mechanism comprises 2 square flanges mounted back to back with a hinge along one edge. In the upright operational position the flanges are bolted together and the structure behaves as a conventional flanged fixed post.
To lower the post the operator has to pull the post towards the lowering direction and provide support during the lowering. As the flanges separate the spring provides increasing resistance such that the operator can easily maintain a safe lowering. Raising is a simple reversal of lowering.
The post is of a lightweight design to be handled by 2 men and installed without the use of a crane or specialised equipment.
The post design is protected under a Registration of Design, No. 4024724, awarded by the United Kingdom Intellectual Property Office.Click Here Download The Hinged Lightweight Post Brochure
