TM5-3810-305-10 The increased possibility of inadequate wraps remaining on winch drum occurs when operating with a higher number of line parts than are required for load being lifted, particularly at longer boom lengths and high boom angles. Sufficient cable is initially provided to allow the hook block to reach ground level when reeved for the required parts of line indicated on the Capacity Chart for all given loads. Reeving with more parts of line than required may result in all of the cable being payed off the winch drum. CAUTION Keep tension on cable to prevent damage from slack. 3. Raise boom to required angle, consulting the boom angle indicator for the boom angle. The boom elevation is controlled by a hand lever. To LOWER boom, push lever forward. To RAISE boom, pull lever back. Improved control is obtained by operating engine at low speed while “metering” controls. Always operate and release controls slowly to minimize dynamic effects of load. During a lift, where precise control of load is required, do not attempt to use more than one function at a time. l Always use a qualified signalman and observe load while the equipment is in operation. l When spotting a load, it may become necessary to alter the boom angle or length. If adjustment is necessary, consult the LRT 110 Capacity Chart before performing a lift. Failure to follow this procedure could cause DEATH or serious injury. CAUTIO N Always consider possible ob- structions which may be encoun- tered during swings when vary- ing boom height or length. Think swing through, consider- ing all obstacles, before making swing. Failure to follow this procedure could cause damage to equipment. When lifting with the LRT 110 Crane, a signal- man must always be used to direct the operation. Limited visibility to the rear is caused by upper- structure being in the operator’s line of vision. I CAUTION I Never hold controls in an “acti- vated’ position once hoist/lower cylinder or extend/retract cylin- der has reached its limit of travel. This can cause overheating of hydraulic oil. 4. Swing boom over load. Upperstructure and boom swing is controlled by swing lever. To swing boom to the RIGHT, push lever for- ward. To swing boom to LEFT, pull lever back. Swing speed increases as lever is moved further forward or back. Swing speed also varies with engine speed. 4-23
