Anchor Windlass DMA Series Overview
The DMA anchor windlass converts power (electric, hydraulic or diesel) through a reduction mechanism into high torque to handle anchor chain retrieval and deployment on ships and offshore units. Designed for a wide range of vessel sizes, the series supports single- and double-chain configurations and multiple drive options.

Key Features

• High load capacity across submodels to suit various vessel classes
• Integrated multifunction design for anchoring and mooring operations
• Reliable safety braking and holding capability
• Optional intelligent control and real-time status monitoring
• Available in electric, hydraulic or diesel drive formats (codes: D/Y/C)
