Horizontal Simplex Crane Detection System
Narrow Beam System (crane specific)

See page 2 of System Brochure for more Technical Data


The MDSµP-II-NB™ Horizontal Crane Detection System for collision avoidance incorporates the very latest COMMANDER™ development in low power microwave technology. The MDSµP-II-NB™ is designed for stand alone operation and can be used to detect stationary or moving targets. The MDSµP-II-NB™ 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’ MDSµP-II-NB™ Antenna (transceiver) with ABS cover to IP65 enables detection of structural objects such as overhead cranes and building end walls. An optional MDS-Tetrahedron™ reflector ensures a good return signal from small targets. This system will operate in two directions by adding a plug-in ‘daughter’ PCB and a second MDSµP-II-NB™ Antenna thus to detect and control forward and reverse directions and speed zones. The MDSµP-II-NB™ system incorporates 3 zone relays (each direction) as standard which can be programmed during installation for the required detection distances and interfaced to warning devices, directional and speed control circuits as required. The MDSµP-II-NB™ system is programmed during installation using the CDS™ programmer unit which connects to the mother 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).
