Multiple lifting appliances. L.N. 280/78.

[1983 Ed.

(2) The contractor responsible for a crane (including a crane with a derricking jib) which has a variable operating radius shall ensure that the crane is not used unless it---

(a) has clearly and legibly marked on it the safe working load at various radii of the jib, trolley, or crab, and, in the case of a crane with a derricking jib, the maximum radius at which the jib may be worked; and

(b) is fitted with an accurate indicator, clearly visible to the driver, which shows the radius of the jib, trolley, or crab, at any particular time and the safe working load applicable to that radius.

27. The contractor responsible for a crane, crab, winch, pulley block, gin wheel, sheerlegs, derrick pole, or derrick mast shall ensure that it is not used if it is loaded beyond the maximum safe working load:

Provided that, for the purpose of enabling tests of any such appliance to be carried out, the maximum safe working load may be exceeded by such amount as the competent examiner appointed to carry out the test may authorize.

28. (1) The contractor responsible for a Scotch derrick crane shall ensure that it is not used-

(a) if the jib of the crane is erected between the crane's backstays; and

(b) unless appropriate measures are taken to prevent the foot of the king post of the crane from being lifted out of its socket or support when the crane is in use; or

(c) to move any load lying in the angle between the crane's backstays.

(2) Where the guys of a guy derrick crane-

(a) cannot be fixed at approximately equal angles to the mast of the crane; and

(b) so that the angles between adjacent pairs of guys are approximately equal,

the contractor responsible for the crane shall take such other measures as will ensure its stability.

28A. Where more than one lifting appliance is used to raise or lower one load, the contractor responsible for such appliances shall ensure that-

(a) each lifting appliance is so arranged and fixed that it is at no time loaded beyond its safe working load or rendered unstable in the raising or lowering of the load; and

(b) a competent person is specially appointed to supervise the operation.
