Rated lads d nt exceed 78% f tipping lads, and include weights f the lad, hk blcks, slings and ther lifting devices. 3. Rated lads are fr statinary and level cranes lifting a freely suspended lad, and have been determined fr ideal perating cnditins. The user must limit r derate lifted lads t allw fr adverse cnditins (such as sft r uneven grund, ut-l-evel cnditins, winds, side lads, pendulum actin, jerking r sudden stpping f lads, inexperience f persnnel, multiple machine lifts and traveling with a lad.) 4. Gantry must be in fully raised psitin fr all peratins.. Crawlers must be leveled t within % n a firm supprting surface. 7. When lifting ver bm must be deducted 40kg. 8. Midpint suspensins are required fr bms 64.0 m (20') and lnger. 9. Bm lengths fr jib munting are 4.72m (0') t 73.m (240'). 0. The bm shuld be erected ver the frnt f the crawlers, nt laterally..
