For the overhead crane commission, usually we will check the two points:
First one is to see the electric hoist lifting & traveling and crane traveling, check whether they can work proper;
Second one is static load testing, for this one, we will test the 1.25 times, 6 tons lifting. The correct performance is crane can lift 6tons one meter from ground. Third one is dynamic testing, for this one, we shall test the 1.1 times, 5.5tons. We shall lift the 5.5tons cargo and see the crane traveling.
