In comparison to the simple form of conveying by leather bag hooked on a rope, the manual winch which is especially used as double drum system with good ball bearings, makes work considerably easier. The integration of anti-friction bearings decreases friction losses. Which calculates the conical angle of drum.įor the purpose of personnel lifting it is important to use safety dogs and breaks. = r drum x (actual load + weight of material + rope weight) In case of static load, the following formula is used: The load moment of hoist is then minimized by the small drum diameter, while the stronger the load is wound up, the weight of the hanging rope is smaller and the drum diameter increases. If the bucket hangs deep within the shaft, the load is higher due to the weight of rope. To equalize the static load moment tapered cable drums were invented. Winch suspension with counter weight and counter rope to lower the necessary leverage. Ore and material conveyance also water transport and passenger lift in shafts and roadways of small-scale mines. With one or two handles the conveying rope is wound up by hand on a direct coupled drum.
