The minimum steady speed wheeled crane commissioning
This is the minimum steady speed of wheeled cranes debug introduced into working conditions, methods and requirements of three parts
1. Debug condition
Base pipe frame, engine rated speed, rated amplitude maximum rated lifting weight lifting
2. Debugging method
Manipulation engine throttle control movement speed and other institutions * are the electric lift table, down, left and right turning movements reach a steady speed as low as possible. Determination of uniform through - determine the distance required time period, drum trucks movement distance of not less than 1m, rotary motion angle of not less than 180. , Were calculated from the rise, fall, swing the minimum steady speed, and with the requirements of crane design data comparison.
3. Requirements for commissioning
(A) single rope hoist rated speed, rated rotation speed, no load rotation speed is not less than the design value.
(2> The maximum rated lifting capacity crane operations, lifting, and turning down the minimum steady speed shall not exceed the total community
