This pantograph model is an independently developed spring-actuated system designed for trams and metro vehicles operating on 750V or 1500V DC overhead traction networks.
It consists of three main components: a single-arm current collection structure, a drive unit, and a spring-based lifting mechanism.
Pantograph raising and lowering are controlled via an electric actuator, with a manual lifting mechanism included to ensure emergency operability when needed.
