Winch reinforcement unit (polyspast) redBTR is a lifting device designed to gain strength and / or change the direction of force (traction).
Used for winches with synthetic rope.
Using a chain hoist increases the traction force, but reduces the pulling speed. Each additional block of strengthening increases tractive effort in 2 times in relation to applied. Also, the use of a block reduces the load on the cable and the winch by half. Thus, the winch motor runs faster and with less energy consumption. Using a chain hoist, you can use a long cable and not be afraid of overheating the electric motor. redBTR winch reinforcement blocks (chain hoists) are made of high quality steel, differ in maximum permissible load and dimensions.
Material - steel. Working load - 4 tons. The maximum rope size is 14 mm. Dimensions - 220x168x48 mm.
