Warner Electric Modified SF1000 Clutch for Diesel-Powered Concrete Saws

Concrete Saws

Warner Electric SF-1000 clutches mounted on diesel-powered concrete saws provide an important safety feature, allowing road construction operators to disengage the diamond blade drive while the engine remains running. This helps the operator safely free blades when they become pinched in the kerf (cut groove) due to thermal expansion and it also allows operators to move their machines using the power drive, with the engine running, but without rotating the blade during the move.

Because these flat saws can weigh up to 1,500 pounds, with up to 60 in. dia. blades, this is a significant ergonomic and convenience benefit. The operational benefits of the clutch gives the saw manufacturer a major advantage in the marketplace without significantly increasing the cost of the equipment. The SF-1000 clutch also gives the saw manufacturer the ability to sell the same model saws in both the European (where the clutch is a required safety feature) and North American marketplaces.

Depending on the model, the flat saws generate 50, 60 or 100 ft.lbs. of torque. The static torque rating of the SF-1000 clutch is 200 ft.lbs.
