Vertical Crane Detection System
with BatBak™ (Battery Back Up System)

See page 2 of System Brochure for more Technical Data

The COMMANDER™ IRVCD™ Vertical Crane Detection System for collision avoidance uses security coded infra-red signals to communicate vertically between cranes on 2, 3 or more gantry levels. Upper and Lower systems have similar hardware and features. All upper crane systems (above level 1) incorporate positional hook monitoring (limit/device not supplied) This monitoring feature provide a level of automation to the crane operating performance. When operational, if an upper crane has one or more hooks lowered then this ‘upper’ crane and any crane on lower levels which approach the intrusion zone will be inhibited from bridge forward/reverse travel motion. This means a crane on level 4 will communicate with a crane on level 1, then others as/if they appear within the intrusion zone. All systems have a closed security loop incorporated to ensure signalling is maintained and has not failed. Power for each IRVCD™ crane system is derived from a separate AC supply which remains isolated and active when the normal crane power supply is switched off for maintenance or other purposes. In the event a full power loss, the systems BatBak™ (battery back up system) (built in) ensures a continuous given period power supply and will maintain presence status and continue to signal cranes above and below its own level. In the event of full power loss to the crane the system will go into visual and audible alarm mode to signal personnel of the condition. A key is required to silence the activated system. This signalling can be repeated by radio link to a ground based administration location. The IRVCD™ system is supplied ‘scheme ready’ to the installer or OEM.

The E1™ Infrared ‘conditional’ travel over-ride system comprises an 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 receiver decoder as required in other applications is not required for the IRVCD™ as the scheme hardware incorporates pre-configured facility for interface connectivity. The hand held transmitter features AutoStart™ and operates using a specific periodic transmission system. The E1™ Infrared 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).
