PANDROL remains in the forefront of rail fastening development. Here are some of our latest innovations.
PANDROL FASTCLIP FE
The new PANDROL FASTCLIP FE system utilizes the proven technology of the original FASTCLIP assembly to create a lower cost assembly which retains the features that have provided railroads and contractors with reduced costs for installation, de-stressing and maintenance.
An optimized clip shape results in a cost savings and the newly designed and strengthened shoulder reduces weight and provides a lower profile. The new and innovative collar, which combines the side post insulator and heel seat for the clip, has excellent insulation properties and its high lateral stiffness and durability give excellent gage retention.
The PANDROL FASTCLIP FE system provides a nominal toe load of 2,250 pounds per clip. As with all FASTCLIP assemblies, all components are pre-assembled on the tie at the tie plant and arrive at the site ready for installation. The system is fully compatible with automated track machinery.
The innovative PANDROL VICTOR® system combines the durability of an AREMA tie plate with the benefits of Pandrol's line of resilient fastenings. The flat tie plate provides the maximum bearing area, while the use of Pandrol's fastenings provides all of the advantages of resilient fastenings - holding power, prevention of rail rollover and reduced maintenance.
Testing at TTCI, with 39 ton axle loads, has shown a five-fold decrease in gage widening when using resilient fastenings on wood ties.
Vortok® De-Stressing Roller System
Pandrol USA is marketing the Vortok® De-Stressing Roller system in the United States. The system is designed to improve the accuracy and efficiency of rail de-stressing operations. The VSR system brings a new level of performance, safety and efficiency to the de-stressing process. The system reduces the time it takes to complete the work, reduces the number of people required, provides a safer operation than current de-stressing methods, and results in higher quality track.
Shoulder Face Repair Shim
Pandrol has developed and has a patent pending on a stainless steel shim for replacing worn shoulders in track. When epoxied onto worn shoulders and used with custom designed insulators, track gauge can be restored. This repair procedure renews tie life and eliminates the need for tie replacement.
PANDROL® SAFELOK I Long Reach Clip
PANDROL® Long Reach SAFELOK I clips provide a fastener that extends 1/2 inch further on the rail base and generates a slightly higher toe load. This longer reach SAFELOK I fastener has been developed as a safety feature to ensure clip retention and increase holding capabilities on high degree curves where shoulder wear and insulator wear are more prevalent.
ANTI-ABRASION PAD AND INSULATOR ASSEMBLY
The new four-part integral abrasion resistant tie pad and insulator assembly is designed to control rail seat abrasion on concrete ties. The components are manufactured from high quality engineered polymers.
These assemblies include a resilient and durable top pad, an anti-abrasion plate, a sand resistant and water repellent gasket, and the side post insulators. All components are assembled on snap fit restraining lugs to ensure security during shipping and service life and arrive at the job site as a single unit. The system is designed to seal out sand, dirt and water from the rail seat. Interlocking studs and dimples, which are an integral part of the plastic plate and pad, resist differential movement of the parts and improve longitudinal restraint.
The pad shown is used with the SAFELOK III fastener. This type of pad is also available for FASTCLIP, SAFELOK I, and 'e' Clip.
PANDROL® SAFELOK III
The SAFELOK III system meets the need for fast, efficient track installation and reduced maintenance cost. SAFELOK III is pre-installed on concrete ties with clip, pad and insulators in place, ready for track installation. The dual insulator design results in extended component life and significantly reduced maintenance costs.
The SAFELOK III system meets or exceeds the standards and requirements established by the world's major railroads and provides optimal performance over a wide range of operating conditions.
Since SAFELOK III is captive on the tie, there is a significant reduction in manpower during rail installation and adjustment.Benefits Include:
- All components can be pre-assembled on concrete ties
- Fast, fully mechanized application
- All components remain on the track during rail change out or de-stressing
- Outstanding durability
- Exceptional gage retention
- Dual insulator design promotes long insulator life
- No metal-to-metal contact to the clip/rail interface
PANDROL SRS is designed to reduce vibration and noise and is ideally suited for transit and freight applications. The Single Resilient System (SRS) assembly consists of a cast base plate and a resilient pad and can be used on wood, composite ties or slab track. This non-bonded, low-profile system is fully insulated, provides excellent stray current protection and is available in FASTCLIP and 'e' clip designs.Benefits Include:
- It is economical and competes favorably with standard DF assemblies
- It can withstand freight traffic
- Components can be easily changed to meet loading requirements
- All common rail sizes can be accommodated
- Vertically serrated holes allow for lateral adjustment
- Footprint designs that match current DF assemblies
- FASTCLIP plates are pre-assembled
PANGUARD is designed to provide a rail fastening system that would reduce both noise and vibration. Such a system is highly desirable in tunnels in transit applications.
The PANDROL PANGUARD system suspends the rail from the web and fishing surface with resilient blocks. The resilient blocks are held in ductile iron side plates that transfer the vertical load to the tie. This system is in use on MBTA and various properties around the world.
