About FibreTrac
MacGregor fibre-rope cranes use a novel capstan, developed by Parkburn, as a traction winch. It consists of two interlocking drums slightly angled and offset in relation to each other. The drum geometry creates a natural and stable helix without generating any fleeting forces, so the rope does not twist on the drum as it is gently de-tensioned. The winch system can be delivered with digitally-controlled electric or hydraulic-drive units. Features include integral active-heave compensation and power regeneration capabilities.
The open design of the winch also assists with rope cooling, further assisting in eliminating the heating and degradation problems associated with on-load fibre ropes stored on winch drums. Importantly, it can accommodate non-uniformities resulting from splices in the rope.
MacGregor has also developed an exciting modular fibre-rope retrofit solution, which is based on the same technology. This allows customers to convert their existing wire-rope cranes to fibre-rope versions, unlocking their full potential.

Increased flexibility and cost-efficiency
Leveraging proven technology and extensive knowledge, the MacGregor FibreTrac crane offers enhanced load handling at unrestricted water depths:
- Increases owner and operator scope of operation.
- Enables full lifting capacity of the crane to be used over a wide range of water depths.
- Minimal-weight, high performance fibre rope does not add to crane load, irrespective of rope length.
- Gentle handling and a controlled environment safeguards rope integrity, maximising lifetime.
