(3) Every crane whose safe working load varies with its operating radius shall, subject to paragraph (4), be fitted with an accurate indicator, clearly visible to the driver, showing the radius of the load lifting attachment at any time and the safe working load corresponding to that radius; and in this paragraph the reference to the radius of the load lifting attachment is, in a case where the attachment is suspended on the end of a rope, a reference to the radius of the attachment when it is vertically below the point at which the rope is suspended from the crane.

(4) In the case of a telescopic jib mobile crane operating with a fly jib or a locked jib extension, it shall be sufficient compliance with paragraph (3) for the said indicator to show the angle of inclination of the jib at any time and the safe working load corresponding to that angle; and in this paragraph“fly jib” means an accessory fitted to the jib to form an extended jib, and“locked jib extension” means a part of the crane extended from the jib manually to form an extended jib.

(6) Every item of lifting gear which weighs a significant proportion of the safe working load of any lifting appliance with which it is intended to be used shall, in addition to the requirement in paragraph (5), be clearly marked with its weight.

(7) Every mobile crane having either a fixed or a derricking jib shall, subject to paragraph (8), be fitted with an automatic safe load indicator of a type approved for the purposes of regulation 30 of the Construction (Lifting Operations) Regulations 1961(1), which indicator shall be—

(a)properly maintained; and

(b)tested and inspected by a competent person at appropriate intervals.
