COMPACT, RELIABLE AND DURABLE PANTOGRAPH CONTROL SYSTEM

CUSTOMER CHALLENGE

The challenge for Norgren’s engineers was to design a pneumatic system that would retract the pantograph from the overhead power cables when required. The system had to fit within the small area at the base of the pantograph structure, so it had to be compact, as well as reliable and durable.

NORGREN SOLUTION

Norgren’s design team engineered a customised solution using a range of standard products that were adapted to the task in hand. This solution offered a safe and reliable retraction method, and met the tight space constraints specified by the customer.

The pneumatic system enabled the pantograph to be withdrawn from the overhead power cables both quickly and reliably, and it was small enough to fit within the existing footprint of the pantograph. Norgren gave the customer a cost effective feature which improved and added value to their existing product.
