DOUBLE RESILIENT BASEPLATE ASSEMBLY

PanDROl PReSentS:

DOUBLE RESILIENT BASEPLATE ASSEMBLY

The Pandrol e-Clip baseplate is mounted on a studded natural rubber pad which provides resilience. This can be tuned, within limits, for axle loads and stiffness requirements. There is no need to grease or re-tighten the fastening elements as the rail fastening elements are non-threaded to provide low maintenance.

1. Nylon sidepost insulators

2. Pandrol brand e-Clip

3. Studded rubber baseplate pad

4. Cast iron baseplate

5. Studded EVA rail pad

6. Anchors

• Different variants of anchors may be supplied depending on the construction method

• Assemblies may have 2 or 4 anchors depending on track conditions

The PANDROL DOUBLE RESILIENT BASEPLATE ASSEMBLY is typically suited for installation in non-ballasted tracks and areas where a reduction in ground borne noise and vibration is required. The system suits either top down or bottom up construction techniques.

As with all Pandrol fastenings, the Pandrol resilient baseplate system is backed by many years of worldwide experience and an unmatched depth of technical understanding from Pandrol’s technical engineers.

ExPEriENCEThe system has been in use since the mid 1980’s and is installed on MRT and LRT systems in major cities such as Hong Kong, Singapore, Sao Paulo, Dubai and Istanbul. It is also installed on main line slab applications and steel bridges on axle loads up to 22.5 tonnes.

AdjuStAbility Typical lateral adjustment of ±3mm can be achieved using an eccentric bush, in 1mm locked steps (additional lateral adjustment can be provided against specific requirements). Typical vertical adjustment of up to 20mm can be achieved using shims.

MAiNtENANCE All resilient parts and wear components are fully replaceable in-situ. The system has two independent levels of electrical insulation and uses Pandrol threadless fastening technology, providing low maintenance throughout the life of the system.
