Series: OHW/OHR -  hydraulic winches for offshore applications

A set of very compact lifting and pulling winches specially designed for offshore applications or for any other hazardous environment if space is limited. Winches designed to fulfill independent third party requirements such as ABS, DNV, Lloyds, etc. Standard winches can be fitted with several options and accessories.They are prepared for manriding. Their heavy duty planetary gearbox and brake are set up within its drum core - both saves space and protects from external damage. Winches are provided without a control valve as standard (but they have a single acting shuttle valve).
