Rotary Joint for High-Speed Rail Train Water Supply Systems
On-platform water supply interface for high-speed rolling stock
Overview
High-speed trainsets are replenished with water at platform water supply columns while standing at stations. The supply column's swing arm carries water to the train through a rotating joint that must seal reliably through the coupling and retraction cycle, thousands of times per year, often in exposed weather. The Ruitus rotary joint for rail water supply is engineered for this duty: dependable sealing through repetitive swing cycles, connection interfaces matched to platform water column standards, and materials selected for potable water service. Ruitus works with platform equipment manufacturers to match the joint to the column design — send your specification for a tailored proposal.
