Gearboxes for bridge travel drives
Our portfolio offers customers two bridge travel drive solutions:
ELECTRICAL WHEEL – the gearbox in the travel wheel itself; or
PK – the aggregate is composed of planetary gearbox with electric motor and connected to a separate travel wheel.
ELECTRICAL WHEEL – the entire aggregate consists of an electric motor connected by a flange to a high gear-ratio planetary gearbox, where the gearbox is the travel wheel itself. A high-quality all-rubber or steel banding is mounted on the gearbox.
EK 517 electrical wheels are suitable for bridge travel drives in settling and secondary settling tanks.
EK 351 electrical wheels are suitable mostly for bridge travel drives in both sand and grease traps and in settling and secondary settling tanks. They work in tandem on a single travel bridge. A connection plate or flange attaches the aggregate to the bridge. It is often used to repair existing bridge travels as it can be an easy and quick substitute for the original drives, requiring minimum adjustments to the bridge frame.

PK gearbox aggregates are suitable for bridge travel drives in circular settling and secondary settling tanks. Depending on the tank’s diameter and installation site, the drives use either single or double aggregate, or a combination of a PK gearbox aggregate with a VK tug wheel. PK aggregates are used mostly to repair existing bridge travels, enabling easy and quick replacement of the original drive.
The entire aggregate consists of an electric motor connected by a flange to a high gear-ratio planetary gearbox. The hollow output gearbox shaft glides directly onto the travel wheel shaft.
