An Introduction to Pandrol’s PANGUARD System
The PANGUARD assembly for concrete ties or slab track is constructed as follows…
Pandrol PANGUARD
Cast iron plate with stems and shoulders …
… cast into concrete tie or slab
Natural rubber wedges support rail …
… and are in turn supported by cast iron side plates …
… which are locked in place with cast iron wedges …
… spring steel clips locate these for added security …
… and a natural rubber overload pad prevents excessive deflection
PANGUARD on concrete ties, ready forinstallation on London Underground
Pandrol PANGUARD baseplate for London Underground
Same performance … … easier to install
Test of a competing systemwith very resilient baseplate pad,and virtually all lateral loadtaken by the anchor bolts.
0.079 inch
0. 083 inch
PANGUARD – Tested under sameload. More vertical resilience with 1/10 of the lateral deflection, and minimal shear load on anchor bolts.
