(NOTE: A Crane of any length up to 40 feet is practical that does not exceed in number of feet the distance from the 

 point where the base of the Crane is to set to the plate on which the rafters rest, multiplied by 2 ' o- 't is well to 

 remember that there is the same inward pressure at the base of a Crane as outward pull where the guys are attached. This 

 pressure and pull, however, comes at the barn's strongest points — the mow floor and the rafter plate, and a little 

 bracing is all that is necessary to neutralize the strain on the end of the barn. See Figure 1067. page 186. 



In erecting Crane see that the longest guy wire carries enough of the weight to pull it taut, intermediate guy wires may 

 be slightly slack but the guy reaching to the end of the Crane should always be taut.) 



A Louden Swinging Steel Crane is attached to the barn above the door in Hne with the Litter Carrier 

 track, and extends out over the yard for a distance of 1 2 to 40 feet without posts or supports of any kind 

 in the yard being necessary. 



The use of the Swinging Crane not only makes unnecessary all posts and supports in the yard, but 

 gives a far greater area in which manure may be dumped as the Crane may be swung around from left to 

 right till it strikes the sides of the barn. To all practical purposes a Swinging Crane of 30-foot length 

 gives a dumping area as great as a straight, rigid track running out a couple of hundred feet from the barn 

 door. To empty the Litter Carrier direct into wagon or spreader, all that is necessary is to drive to any 

 point within the Crane's radius. 



The Swinging Crane is also a great convenience where litter is to be dumped on the opposite side of a 

 yard fence or down a hillside from the barn, and, as it may be swung around close up against the barn 

 when not in use, is entirely out of the way of passing stock or wagons.
