  1. Basic function: measuring speed<\/strong>\n
    <\/div>\n

    Mounted on the drive shaft of the crane lifting motor, the speed and position pulse signals of the shaft are collected in real time and passed to the inverter\/control cabinet for controlling the speed and precise positioning of the crane lifting; up to 12,000 revolutions, the shaft can carry large radial\/axial loads, and the metal shell is IP66 waterproof and dustproof, which is suitable for heavy-duty and harsh work in steel mills and ports.situation.<\/li>\n

    Mandatory requirements of national lifting regulations\uff1aFrequency conversion crane lifting mechanism must be equipped with overspeed protection<\/strong>, To prevent the hook from falling out of control and the reel from speeding.<\/div>\n<\/div>\n
    \n
      \n
    • Electronic overspeed (digital switch)<\/strong>: The encoder measures the speed in real time, the speed exceeds the set value, and the relay outputs an electrical signal to notify the inverter to stop and brake. The accuracy is high and the data recording is convenient.\uff1b<\/li>\n
    • Mechanical overdrive (centrifugal)<\/strong>: It does not rely on power supply, and has a purely mechanical centrifugal structure. If the power failure fails, the switch can still be triggered, the safety circuit of the crane can be cut off, and the brakes can be forced. It is the first choice for old metallurgical cranes.<\/li>\n<\/ul>\n
