1. Overview
   MSFP intelligent crane anti-collision device is an electronic instrument with safe operation which is used to monitor and restrict the moving range of travelling block, provide the operator with real- time position of travelling block, and provide the protection of upper anti-collision, lower anti-smashing and overspeed brake.


2. Main Functions
    . Display the current operation state of system, display normal operation, alarm or brake;
    . Digital display operation height and speed of travelling block, graphic display operation height and direction of travelling block;
    . Set the upper/lower limit position of travelling block’ operation;
    . Set the highest speed range of travelling block’s operation;
    . Set the height display mode of travelling block, that is percentage mode and length mode;
    . Automatically judge the operation direction of travelling block;
    . Protect the travelling block from upper collision, lower smashing in operation;
    . When the operation speed of travelling block exceeds the preset speed, it will automatically control travelling block’s operation, and start brake function to protect equipment and staff with sound-light alarm;
    . Anti-collision warning function: when the rising height of travelling block exceeds 85% of full height or falls down to 15%, the system will give sound-light alarm;
    . Test brake function: to ensure the system can carry out accurately and effectively the protection measures when emergency happens.
