TM5-3810-305-10 Never lift and swing a load directly over operator’s compart- ment or over ground personnel in the  work  area.  Failure  to  follow this procedure could cause DEATH or serious injury. CAUTION ALWAYS  START  AND  STOP SWINGS   GRADUALLY. Stopping swing too abruptly cause load to oscillate and impose side loads on boom. will cause damage to boom. will This When ready, try for a smooth, controlled, safe swing.  The  swing  should  be  SLOW.  Start SLOWLY and allow load to buildup just enough momentum to carry it through to the point where it is to be lowered. Begin slowing swing in advance of point where load is to be lowered. Slow swing GRADUALLY, enabling it to “coast” to a stop over desired spot. If properly executed, load will hang motionless when swing is terminated. If load is oscillating, swing was made too rapidly and/or stopped too abruptly. 5 . . Extend boom to desired length (refer to the Capacity  Chart).  EXTEND  boom  by  pushing extend/retract lever forward and RETRACT by pulling lever back. CAUTION    Never pull to the side with a crane  boom.  Crane  booms  are not designed for excessive side pull and may collapse if sub- jected to excessive side loading. 6. Lower hook block to load and fasten hook. Make sure hook is properly engaged in slings or lifting device employed to make the lift. Be certain hook latch is not supporting any of the load (refer to warning decal on hook block). Hoisting or lowering load with winch is con- trolled by winch lever. To LOWER load, push lever forward. To RAISE load, pull lever back. Improved control is obtained by operating engine at low speed while “metering” control.. Always actuate and release this lever slowly to minimize dynamic effects on load and to prevent “bird caging” of cable on winch drum. l l Never operate equipment with personnel on the hook or a load.  Failure  to  follow  this procedure  could  cause  DEATH or serious injury. Crane operators must always be prepared to take emergency action while a load is suspended  in  the  air.  Never leave  the  operator’s compartment with a load suspended.  Failure  to  follow this procedure could cause DEATH or serious injury. 7. Lift load to desired height. Do not lift higher than necessary. The LRT 110 Crane is equipped with an anti-two block system. If hook or block is raised too close to boom head, a warning light appears on panel. If horn switch is activated, an audible warning will sound. This vehicle is also equipped with control disconnects to prevent winch from raising load and boom from extending or lower- 4-24
