The Louden Crane is built regularly In 

 lengths of 12 feet, 22 feet, 30 feet and 40 feet. 

 Each Crane will carry many times any prac- 

 tical load. In factory test a 40 -foot Crane 

 was operated with a 1,500 pound weight at 

 extreme end. It is absolutely guaranteed to 

 handle 1 ,000 pound loads. For very heavy 

 loads, however, care should be taken to see that 

 the timbers of the barn, to which the Crane is 

 anchored, are strong and well braced. 



Construction 



The Louden Swinging Steel Crane is guar- 

 anteed to be the strongest and most substan- 

 tial Crane for Litter and Feed Carriers on the 

 market. All Louden cranes 30 feet long or 

 over, are side trussed. This is the only Crane 

 made that is side trussed with tubular steel 

 (see Fig. 1067). It is built on the same scientific principle employed in steel bridges, and is 50 per cent 

 stronger than a more cheaply constructed wire trussed Crane. It is absolutely impossible for it to buckle 

 under the heaviest load, as the tubular steel truss will handle an enormous back pressure. 



Cranes under 30 feet in length are 

 not side trussed. 



Figure 1062 shows the construc- 

 tion of the Crane at doorway. 

 A special malleable iron vertebrae 

 hinge made in our own factory in- 

 sures the free, easy, and steady move- 

 ment of the Crane. It will handle 

 double the load that it will ever 

 be called upon to handle. 



Where swinging crane passes 

 through sliding door and this hinge 

 is used, the door should be made 

 double. Doors can then be notched 

 to fit closely around the hinge as 

 shown in Fig. 1062. The type of 

 hinge used is the best for the 

 purpose. 



Swinging Track at Door — Fig. 791 



Specificatiotis 



One set of fittings consists of malleable hinge 

 and bolts for attaching to barn, steel supporting 

 rods and special clamps and fixtures for connect- 

 ing to track at outer end. 



In instances where the litter carrier 

 track extends out of the barn at the end 

 where the hay is taken up, it is some- 

 times desirable to have a section of track 

 which will swing around out of the way 

 or lift out. This plan is shown in 

 Fig. 791. 



Please remember that we have a 

 solution for any problem that may come 

 up in the installation of our goods.
