In 2013, EKA Limited carried out a refurbishment and upgrade programme on the main recovery and auxiliary winches on the RRV. The original installation included the ROTZLER TR200 20t twin capstan winch and the HZ010 1t auxiliary drum winch. These winches had an intermediate control system which allowed electronic control, but were not compatible with modern CAN-Bus control systems. The refurbishment and upgrade programme upgraded the base winch unit to the modern /6 control system – a fully compliant CAN-Bus control system.
One of the benefits of carrying out this upgrade, in addition to mid-life refurbishment, was to introduce system, component and support commonality. After the upgrade was complete, the MLRS RRV winch systems shared a broad range of components and control system protocols with Support Vehicle (Recovery) – the SuperCompact equipment installed on the MAN/RMMV SX-45 Support Vehicle.
