Class of Work of the crane: For the purpose of design of their frames, every crane and hoist is classified with respect to the frequency of application, variation of magnitude of the load and the effect of impact. Cranes are divided into four classes. Light duty cranes come under class I type. Heaviest duty crane are class 4 type. Light duty and Heavy duty cranes are discerned by the working period, effective load and dynamic effect. It should be remembered that this classification is applicable to the entire crane and the structure. The working period is short if the crane is operated for less than 500 hours per year. The effective load is high if the crane is used to lift loads greater than two third of its safe working load on more than one thousand occasions per year. The dynamic effect may be considered low if the speed of travelling of both crab and bridge or hoist are each less than 100 m per minute. If the speed of operation is higher than this the dynamic effect is high.
