The Speed Sincher is a mechanical device which tensions open-bodied deck-cargo lashing turnbuckles, which are used extensively in the Pacific Northwest in shipments of logs and lumber. Powered by a gasoline engine and weighing 40 pounds, this unit is highly portable and can tension individual cargo lashings to a force load of 7,000 pounds, in 5 to 25 seconds, depending on the amount of take-up required.
The manufacturer reports Speed Sinchers have rapidly gained acceptance on the Pacific Coast because of: (1) ability to drastically shorten turnbuckle maintenance and onboard lashing time; (2) great improvement in cargo security; and (3) adaptability to existing ships gear at a very low cost.
It is reported three men using one Speed Sincher can tension a typical ships complement of 80-100 turnbuckles in under 40 minutes, substantially reducing manhours per vessel lashing time. Speed Sincher provides uniform and consistent tightness of cargo lashing chains. The load is pulled together, which helps to reduce the number of gaps. Turnbuckles with less than minimum take-up after tightening can be quickly unwound, the chain shortened, and retightened, leaving adequate allowance for at-sea relashings.
In conjunction with open bodied turnbuckles with cross-sectional dimensions not exceeding 3½ inches by 1½ inches, Speed Sincher is particularly fast and economical.
