Calculating overhead crane big wheel pressure factors to be considered
How large number of construction plant cost savings presumably each investor concerns, how to more accurately calculate the overhead crane big wheel pressure:
(1) if the maximum lifting load, which should be based on the actual needs of the
Hoist and trolley position calculation. In general, when the crane lifting the maximum load, often in a car near the middle of the main beam, then the cart wheel pressure is clearly better than the car is in the end when the main beam is much smaller.
(2) If the car runs to the end of the main beam, the load should be based on the actual amount of time to calculate. In general, when the car runs to the end of the main beam, it is usually not lifting the maximum load, then the cart wheel pressure is clearly better than lifting the maximum load is much smaller.
(3) If the
hoist and trolley is neither lifted nor maximum load is the minimum load, and run in the middle of the main beam and the end portion.
In summary, in the past on the bridge
lift hoist carts wheel pressure calculation method is not perfect, accuracy is poor, resulting in calculated crane wheel pressure is too large, plant design is too conservative and caused a lot of waste. Improve security should be based on the correct algorithm and the use of advanced technological means and the right measures to complete (such as increasing the safety factor, increasing the limit and warning measures). This will not only reduce the maximum
Hoist equipment wheel pressure, and can save a lot of ground plant cost.
