The crane industry uses both hydraulic rotary unions and electrical slip rings, and when appropriate, integrated fibre optic rotary joints (FORJs) and high accuracy encoders for slewing.  Slip rings are used where the turning movements above 360° are required and where a drag chain would hinder movement.  Slip rings are primarily used in crane technology for power and data transmission. Under heavy-duty conditions, all rotating components of the cranes (e.g. jib arms and grabs) must be reliably supplied with power and data in indoor and outdoor applications.

We understand the pain points and market drivers associated with slip rings in the crane industry:

> Increase in ports moving towards automation so the demand for information and ROV is higher

> Today's on-demand society - The reduction in downtime is vital. Demand for high-quality components that are easy to maintain

> Modular crane offerings enable:  Upgrades, Easy increase in the number of channels for lighting, Sensor and control equipment, Reduced cost across slip ring variances

> Silver brushes that reduce footprinting and burnout on rings

> Lack of time and people to carry out maintenance works

We pride ourselves in the relationships we build with our partners to ensure the design, quality and serviceability of our solutions into the crane market match the expectations of our clients, whilst taking into account environmental and circular economy considerations to ensure a win-win solution all round.


Circular Economy

A major step we've taken to improve our processes is transitioning toward the circular economy
