Resil- ient bushings the flange bolts cushion the shock starting, eliminate strains the drive shaft and bearings, and transmit power without vibration noise.

This new Chane Sooner later the owner noisy crane faced with excessive nance and repair costs, because noise crane means that vital parts are rubbing together, producing excessive wear. Smooth, efficient operation with low power consumption and minimum time.out for repairs can obtained only when proper care has been given the design every vital point. Whiting engineers have provided many extra features cranes give quiet operation with less wear. gear wear have been reduced using quiet, smooth-running, precision-cut herringbone gears. These gears outlast ordinary spur gears two one. Gear centers maintained heavy-duty, anti-friction roller bearings. Flexible tapered-tread drive wheels, and rotating axle bearings reduce friction, vibration, and binding. When you buy crane, sure buy quiet Whiting crane. will give you longer wear.
