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.

5. The rope must be kept round,not loose,even under the maximum load.

6. The rope must be anti-rotation structure.

Pls measure the change of rope diameter under different load

Groove Drum Composition: Drum core, Flanges, Shaft, Etc
Processing: Rope drums with grooves cut directly into them.Winch drum with flange, the LBS groove is cut directly into the body of the drum, according to customers’ requirements, the flanges are either welded or screw-bolted. groove geometry is determined by rope construction, diameter and length, and by application. the drum has the required mounting dimensions for the actual operating conditions.
