Commissioning bodies wheeled cranes


This paper describes the debugging methods wheeled cranes , pay attention to when debugging to make a record , and precautions
( A ) Lifting mechanism
1 . Debug condition
( 1 ) basic boom , pulley maximum magnification , no load .
( 2 ) basic boom , pulley maximum magnification , the maximum rated capacity
( 3 ) to the maximum line pull .
 2  Debugging method
 When the engine is rated speed , in the fully open position joystick uniform Scissor lift ( -1 ; descending ) test load , measured at the time of the trip A2 plexus, pump output oil pressure, flow rate ( speed ) , or generator output current, voltage. Calculate the nominal single rope speed, maximum rated lifting reorganization lifting ( Factory descending ) drive power transmission efficiency and load lifting ( decrease ) when the power and efficiency.
    ( Two ) slewing mechanism
    1 . Debug condition
    ( 1 ) basic boom , maximum elevation , no load, the engine rated speed .
    ( 2 ) basic boom , the maximum rated capacity , the corresponding nominal amplitude , safe rotation speed .
    ( 3 ) basic boom , the maximum rated capacity , the corresponding nominal range , the minimum steady speed .
    2 . Debugging method
    Determination of uniform rotation when the rotation angle ( factor ) , turnaround time , the hydraulic pump output , flow voltage. Calculated rotation speed, power .
    ( Three ) luffing
    L debug condition
