Designed to the standards issued by the classifi cation bodies and it meets the UK HSE regulations for personnel lifting operations on offshore installations. The winches are dedicated personnel lifting winches supplied with full material traceability. They have passed EC testing for these applications, i.e., both the winches and their technical fi les are in compliance with the requirements of the EC Machinery Directives.

The MR 30 FL winches have been specially designed for personnel lifting applications in which a safety harness or a boatswain´s chair is used on fi xed installations with a total WLL of 150 kg. The MR 30 FGL winches have passed EC testing for these applications, i.e., both the winches can be supplied with a Lloyds Register of Shipping (LRS), ABS or DNV Design Appraisal Certifi cate.

The MR 50 FL and MR 60 FL have been designed for use with assemblies using a platform, basket, carrier, etc, with a total WLL of 500 kg for the MR 50 FL and 1000 kg for the MR 60 FL.
