Horizontal Full Duplex Crane Detection System
BatBak™ (Battery Back Up System)
Compatible with previous
IRCDS-HSD-II™ systems

See page 2 of System Brochure for more Technical Data


The COMMANDER™ IRCDS-HSD-II™ Horizontal Crane Detection System for collision avoidance is designed for continuous bi-directional communications to create a high integrity closed safety loop. Each IRCDS-HSD-II™ system requires a partner device (on the opposing crane & direction). The system cannot be used in a retro-reflective stand alone mode. The IRCDS-HSD-II™ system is supplied as an easy to install product comprising a purpose designed and constructed sheet steel CIU™ (Central Interface Unit) with fitted ports and houses a single high quality programmable microprocessor controlled printed circuit ‘mother’ board (PCB) with power supplies, MLC and 3 interface zone relays. A remote mount ‘plug in’ Duplex-400E™ transceiver device enables communication with partner IRCDS-HSD-II™ system(s). This system will operate in two directions by adding a plug-in ‘daughter’ PCB and a second Duplex-400E™ transceiver device thus to detect and control both forward and reverse directions and speed zones, importantly the IRCDS-HSD-II™ system is compatible with the previous IRCDS-HSD-II™ system. This system configuration is more cost effective and simplistic method of expansion and future changes to client user working practice. A BatBak™ (battery back up unit) will provide standby power for both directions of communication. The IRCDS-HSD-II™ system is programmed during installation using the CDS™ programmer unit which connects to the mother and daughter PCB. The input settings are stored in memory, this prevents any tampering by unauthorised persons after installation set up.


The E1™ / RD-05™ Infra-Red ‘conditional’ travel over-ride system comprises a receiver decoder, infra-red receiving sensor which requires to be strategically positioned under the crane structure thus to ensure a suitably defined and controlled operational zone and safe viewing position for a second person (supervisory/banksman) involved in a lifting operation. The hand held transmitter features AutoStart™ and operates using a specific periodic transmission system. The E1™ Infra-Red transmitter must be secured in a safe place when not in use and should only be accessible for use by authorised persons. This system is not meant for usual crane operator use, it is a safety tool to designed to ensure a lifting operation can be effectively controlled within a ‘normally’ inhibited and restricted area (this can be a restricted operating area for a number of reasons).
