2. A Western Gear "Cable Hauler/' Model No. 1142, as 

 shown in Figure 8. The clamping force in this unit 

 is developed by means of three pairs of opposed air 

 cylinders and is transmitted to the tracks by means 

 of three pairs of opposed bogies ;, aa shown on 

 Figure II-2. Since each pair of bogies moves inde- 

 pendently^ englutment of lumps by one pair does 

 not affect the clamping action of the others. The 

 entire upper track assembly rotates about the for- 

 ward drive sprocket. This arrangement ^ coupled 

 with the independently suspended bogies, provides a 

 means for accommodating large discontinuities in 

 cable diameter. 



The xrnit is hydraulically powered, and is rated at 

 10,000-pounds line pull at 50 ft/min on jute-covered 

 cable. It was modified by the addition of entrance 

 and exit guide-roller assemblies to orient the cable 

 fairing properly, as shown on Figure II-3; 



3. A fair leading system consisting of roller 

 assemblies and a trough which guided the fairing 

 to the cable well; 



4. A powered storage reel mounted in the forward cable 

 well^ equipped with a variable-speed drive system 

 and band- type brake. An associated fleeter was 

 mounted just above the reel, as shown in Figure II -4; 

 and 



5. A davit for lowering the depressor over the side.
