Tacoma Bank Operated Cableway, 290ft Span

The USGS Tacoma Bank-Operated Cableways are designed as a safe, low- cost, one-man operation cableway to replace manned cable cars or for sites that are not easily gaged by boat or a bridge. This system uses a extended B-56 sounding reel (not included) which does not need to be mounted permanently but can easily be moved from site to site. Model 4740 extended system consists of bearing posts, main tow cable, pulleys, trolley, vandal protection covers and miscellaneous hardware and used for installations up to 290 feet (90m) spans and up to 220 lbs (100kg) maximum  capacity.

Highlights:

• No personnel over the water - everyone stays on the bank 
• Low cost alternative to manned cable cars 
• Uses extended B-56 sounding reel 
• New design minimizes forces for easy cranking current meter or sample across stream 
• Power drive unit can be used for heavy weights and samplers
