what’re the load lifting test of gantry crane(Part II)?
dynamic test：
Lifting 1.1 times rated load as load to test run, when test run , the auxiliary hoist can’t start 
at the same time), and start again, run, stop, corotation and inversion etc. The time of test
run shouldn’t less than an hour ; the limit switches, safety protection and interlock should
work correctly. Note : the test of hook lifting limit switch of gantry crane should do without load.
