Static sand filling system for train and tram sand boxes
In the rail and tram industry, maintaining optimal vehicle braking and traction is essential, particularly in slippery conditions. Manual sand box refilling is often time-consuming and prone to material spillage, posing efficiency and safety challenges.

Automate sand box refilling with pneumatic systems
The MULTIRAIL® SandPiper, by Schenck Process, is a static sand filling system designed to address common issues in the rail and tram industries. This system automates the refilling of sand boxes or hoppers, essential for effective vehicle braking and traction control. Operators utilize a petrol pump-style nozzle, ensuring easy operation by simply placing the nozzle into the sand box and opening the flow valve. The system pneumatically pumps sand under pressure, eliminating dust emissions via a built-in exhaust system. The automatic stop feature halts sand flow once the sand box is full, optimizing both time and safety. Local dispensing points along service roadways allow multiple roadways to be filled simultaneously, streamlining operations. Designed and manufactured in the UK, the SandPiper offers extensive service and maintenance support to ensure continuous optimal performance.
