    Debugging steps of lifting height limiter in tower
    It can produce a variety of tower crane model products, tower crane equipment and accessories. Has to do the tower hanging standard assembly, can process any manufacturer's standard festival, quality and cheap.
    Tower crane is a large mechanical equipment, its safety can not be underestimated. Therefore, the security equipment of the tower crane is indispensable and must be in good condition. The following explanation explains the debugging steps of the tower lifting the lifting height limiter.

    K40 Mast Section For Tower Crane Masts

    1. The lifting height limiter adjustment is carried out under the empty load of the tower crane, and the micro-switch is pressed separately. Verify the sensitivity and reliability of the two gear lifting limit microswitches. When pressing the micro-switch corresponding to the cam, the power of the fast-rising work block is cut off, and the lifting hook can only rise at a low speed. When pressing the micro-switch corresponding to the cam, the rising power supply is cut off, and the lifting hook can only fall and can not rise.
    2. When the hook is raised, the vertical distance from the top to the bottom of the car is 1.3 meters or 1 meter, and the mobilization shaft is 2Z, so that the cam 2T moves to make the micro-switch 2WK instantaneous change and tighten the nut.

    3. Raise the lifting hook at a low speed so that the vertical distance from the top to the bottom of the car is 1 meter or 0.7 meters, and the mobilization shaft is 1Z, so that the cam 1T moves to make the microswitch 1WK instantaneous switch, tightening the nut.

    4. Multiple blank load verification and correction of the height limit of the two gears.
    5. The height limiter should be readjusted when the doubling rate of the hook pulley is changed.

    Taking QTZ63 tower crane as an example, the debugging method of the moment limiter is introduced.

    Below, take the example of the lifting moment limiter applied on the QTZ63 tower crane to explain the debugging method of the torque limiter.
    1. When the hook is empty, use a screwdriver to distinguish between the stroke switches 1, 2, and 3 to ensure that the three switches are sensitive and reliable.
    1 The stroke switch 1 is a limit switch with a fixed torque of 80 %, press the switch, and the buzzer alarm on the linkage table.
    2 Trip switches 2 and 3 are the limit switches f
