Frequently Asked Questions
What does the Clamplock and Spares category include?
This category features safety-critical point operating machinery and replacement parts, including complete In-bearer and MK3 Clamplock assemblies, high-thrust hydraulic cylinders, lock and detector mechanism assemblies, shims, taper packing plates, and replacement carbon brushes for 110V power packs.
What is the difference between standard and In-bearer Clamplocks?
Standard Clamplocks mount directly between track sleepers, whereas In-bearer Clamplocks are fully encased within hollow steel sleepers. The In-bearer design protects the hydraulic actuator and mechanical locks from mechanical damage and ballast contamination, allowing for automated track tamping without removing the mechanism.
How do Clamplock systems ensure the switch rails are safely locked?
The mechanism utilizes a hydraulic ram to drive a slide assembly that forces a robust lock arm against the stock rail. This mechanically locks the closed switch rail directly to the stock rail, while micro-switches continuously detect the precise position and lock state to communicate safety integrity back to the signaling system.
