This British Standard specifies requirements for power-driven overhead travelling cranes, semi-goliath and goliath cranes for general use.
The clauses of this standard that deal specifically with the means of power do not apply to d.c., hydraulic or pneumatic powered cranes, but the remainder of the standard can be applied to the design and construction of cranes of these types where relevant.
The major new provisions included in this edition of the standard are:
a) the introduction of the new classification system based on that adopted by the International Organization for Standardization
b) the reference where appropriate to the design procedures contained in BS 2573-1 and BS 2573-2
c) the recommendation of preferred lifting capacities, lifting heights and working speeds.
This standard does not apply to fixed runways (usually single track) of the type dealt with in BS 2853 or jib cranes.
