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.
     (4) the maximum line pull Heng l / 5.
     2. Debugging method
     When the engine is rated speed, in the fully open position joystick uniform lifting (-1; descending) test load, measured at the time of the trip A2 plexus, pallet jacks output oil pressure, flow rate (speed), or generator output current, voltage. Calculate the nominal single rope speed, maximum rated lifting reorganization Scissor lift (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.
