CT2: IN-LINE TENSIONER
Line Tensioners
Harken lightweight line tensioners are available with either electric or hydraulic power. 
They provide pull to prevent line slack and overrides. Both in-line and through-deck 
tensioners have powered belts encasing both sides of the line, doubling pull and grip 
capabilities compared to other versions on the market. Tensioner manifolds are 
independently plumbed and include a solenoid directional cartridge to optimize 
tensioner functions. The pay-out circuit includes a pressure-release valve to adjust 
tensioner pull force. The pay-in circuit includes a relief valve to control drag and to 
help prevent overrides.
