5.7.7 Where a wire rope is fixed to a jib or outrigger arm, the rope terminationshould be attached to the outrigger or jib with a shackle or other suitablemeans. Where a wire rope is attached to a working platform, the ropetermination should be attached to a structural load bearing portion of theworking platform with a shackle or other suitable means. U-bolt gripsshould not be used.5.7.8 Wire rope termination should be suitable for their purpose and shouldhave a strength of not less than 80% of the minimum breaking load of therope. Any free end of rope should be finished to prevent unlaying.5.7.9 The end of the suspension rope other than that on or through the liftingdevice or winch should be fixed to the suspension point on the roof rig oron the working platform with a thimble eye splice or ferrule secured eyetermination or other rope coupling device giving a strength of not lessthan 80% of the breaking load of the rope.5.7.10 Wire ropes should be properly maintained and lubricated to preventcorrosion. Ropes with the following defects should not be used:(a)(b)(c)ropes with kinks, birdcage or any other distortion;when the total number of visible broken wires exceeds 5 % of thetotal number of wires in the rope in any length of ten diameters ofthe rope;there is on the rope marked signs of wear or corrosion (regulation23 of SWPR); and(d) reduction of nominal diameter of more than 10 %.5.8 Drum and Pulley5.8.1 When wire ropes pass over pulleys or round drums in winches andclimbers, such pulleys or drums should have a pitch circle diameter ofnot less than 19 times the diameter of the rope.5.8.2 Where the rope terminates at the winding drum, the rope should befastened on to the drum in the manner specified by the manufacturer.31
5.8.3 If the rope is to be wound on to the drum in more than one layer, the ropeanchorage should be so located as to avoid interference with even winding.It should preferably be placed outside the drum flange and should becapable of sustaining twice the maximum force induced in the ropesystem.5.9 Working Platform5.9.1 The working platform should be of sufficient area for the persons employedon it and of at least 440 mm wide (regulation 8(a) of SWPR). The workingplatform should be of sound material and the surface should be slipresistant.5.9.2 Except for the provision of drainage holes, the working platform shouldbe closely boarded, planked or plated (regulation 8(b) of SWPR). Anygap in the working platform should not exceed 6 mm in width.5.9.3 The working platform should be provided on all sides with suitable toeboards placed at a height not less than 200 mm above the level of theworking platform (regulation 8(c) of SWPR).5.9.4 The working platform should be provided on all sides with suitable guardrailsof adequate strength to a height between 900 mm and 1150 mmabove the level of the working platform. The space between any toe boardand the lowest guard-rail above it does not exceed 700 mm (regulation8(d) of SWPR).5.9.5 No guard-rail should fracture or show any permanent deformation whena 50 kg weight is hung on its centre point and the working platform istilted at an angle of 30 degrees.5.9.6 If a working platform extends beyond a suspension point, a factor of safetyagainst overturning of 2 should be ensured in the working platform designin order to provide adequate stability.32
