Q355b Material Wire Rope Cable Winch Drum For Hoist Crane With Shaftoverview of the Wich drum The role of the winch drum is mainly to transfer the speed and
torque of the motor to it through the spindle into the linear speed
of the wire rope around it, in order to lift and lower the object.
• Drum & drum shaft: The drum diameter not less than 19 times of the wire rope diameter. The drum wall can withstand the wrapped tight force of wire rope; the side can withstand the lateral force produced by wire rope. The distance between drum side plate peripheral to the outermost roll rope not less than twice of the wire rope diameter.
Product material: Alloy steel, cast steel, aluminum, all kinds of high-strength steel

Technical parameters and application:
Product advantage: LBS grooved drum, solved the problem of wire rope spooling. Compared with ordinary cordless groove (smooth) drum and helical rope groove drum, LBS rope groove has obvious advantages in the multi-layer wire rope spooling, LBS special groove system makes the spooling of wire rope smooth, and the load of each layer evenly distributed, extend the service life of rope, reduce the wire rope damage, improves the safety of the operation of the equipment, and reduces the problem of mechanical equipment shutdown for changing rope.
Service conditions of Lebus groove 1. The flanges of drum shall be perpendicular to drum wall at any conditions,even under the load. 2. The rope must be kept under tension in the process of spooling so that the rope will be crushed against groove wall. When spooling can not meet this condition,a press roller shall be used.It is generally recommended that the tension of the rope should be at least 2% breaking tension or 10% working load. 3. The fleet angle range should generally never be more than 1.5 degrees and not less than 0.25 degrees. 4.When the wire rope released from the drum goes around the
sheave,the center of sheave should be over the center of drum.
