> I am referring to Canadian standard CSA B 167 Section 6 for load testing.
> Prior to initial use, the following items and components shall be tested:
> a, motions;
> b, limit switches at full speed;
> c, limiting and indicating devices (where provided);
> d, circuits, controls, interlocks, and sequences of operations;
> e, crane motions, holding brakes, and travel brakes with the hook 
> carrying 1) the rated load capacity. The specified speeds at rated 
> capacity shall be attained, provided that the power supply to the crane 
> is as specified; and
> 2) 125% of the rated capacity. The specified speeds need not be
> attained, but the crane shall be able to deal with the load without
> difficulty. Prior to initial use, the vertical deflection of all new, re-
> installed, modified or re-built equipment shall be measured. The vertical
> deflection of the girders produced by the weight of the trolley and the
> rated load shall not exceed the maximum allowed by the applicable design
> specification.
