TM 5-3810-306-10 When moving in tight quarters, post a look-out to help guard against running into objects. Never back up without the aid of signalman. He should assure that the area behind the crane is clear of objects and/or personnel. 6. Traffic - When traveling, keep lights on, use traffic warning flags and signs, and use front and rear flag vehicles. Check state and local restrictions and regulations. Drive carefully and avoid speeding. 7. Towing - Should the crane become mired down, use a tow truck or tractor to free the crane. The transmission or axles can be damaged if you attempt to free the crane without help. On open ground, tow or pull using only on the pintle hook or the two tow lugs installed on each end of the crane. When using tow lugs, always tow using a towbar conforming to MS50048, heavy duty capacity. Contact Organizational Maintenance to disconnect the front drive line before towing the crane. Ensure the drive axle selector is at 2WD-HI, to lockout the rear drive line. STEERING - Steer the front wheels by turning the steering wheel and steer the rear by pushing/pulling the STEER control lever. Used singly or together, these controls provide: 1. Front Wheel Steering. The steering wheel controls the front wheels. This method of steering should always be used when traveling at higher speeds. Turning the wheel clockwise steers the crane to right. Turning the wheel counterclockwise steers the crane to the left. CAUTION Use rear steering only on the job site. 2. Rear Wheel Steering. Rear wheel steering is controlled by the STEER control lever. Pushing or pulling the control lever moves the rear steer cylinders. a. To steer the rear of the crane to the left, push STEER lever forward. b. To steer the rear of the crane to the right, pull STEER lever. c. Four Wheel Steering. Four-wheel steering is performed using the steering wheel and STEER control lever. Four-wheel steering requires turning the front and rear wheels in the same direction. The effect is in a tighter turning radius which will enable you to work the crane in-close when necessary. d. Crabbing. Crabbing implies turning the front and rear wheels in opposite directions (i.e., if the front wheels are steered left, then the rear wheels are steered right). The effect of crabbing is the crane moves in a diagonal direction, enabling you to work the corners of crane in close when necessary. MOVING THE CRANE - FORWARD 1. Position DRIVE AXLE selector switch to either 2 WD-HI or 4WD-LO. 2. Position transmission shifting lever to first gear (1) position. 2-32
