wire rope drum

• Drums – Grooved Drums are the means by which power is transmitted to the rope and thence to the object to be moved. For the wire rope to pick up this power efficiently and to transmit it properly to the working end, installation must be carefully controlled. If the drum is grooved, the winding conditions should be

  As one of the most important accessories in the lifting equipment, the drum plays a vital role in the lifting equipment. It is responsible for winding the steel wire rope, carrying the pulling force and pressure of the lifted heavy object, and lifting and carrying the heavy object with the cooperation of other related crane structures.

• The following formula and table are a convenient method of calculating how long wire rope a drum or reel will hold. Capacity of reel in feet or meters = (A+B) x A x C x K. Where, A = Depth of rope space in inches or mm. B = Diameter of drum in inches or mm. C = Width of drum between flanges in inches or mm.

• Jul 27, 2017 · Wire rope drum is a part of crane lifting mechanism which is used to full in, entwine, and store wire rope. The Wire rope drum is consisted of drum shaft, flange type annular gear, drum hub, bearings, bearing pedestal, etc. Every part of Wire rope drum is engineered and manufactured to meet the operational and safety requirements of industrial crane applications. Drum design basic requirements

• Cast iron. Available in 7-1/4″ and 8-3/8″ pitch diameters. Wire rope sizes listed with each, ranging from 1/4″ to 7/16″. Drums are grooved left hand or right hand. All drums include a set screw for mounting. Steel drums are available in various pitch diameters and lengths up to 93″ upon customer request. All standard drums are on the shelf and ready for same-day shipment.

• Drum Pitch for SINGLE layer minimum: 2.065 x groove radii Drum Pitch for SINGLE layer maximum: 2.18 x groove radii Drum groove depth: minimum ≥ 0.375x d for helical grooved. Hardness: As wire rope has a hardness of about 50-55RC we recommend that the hardness of sheaves and drums is at least 35 RC, better is 40-45 RC.



• Sheaves and Drums – Wire Rope Works

  Sheave and Drum Diameter All wire ropes operating over sheaves and drums are subjected to bending stresses, which eventu-ally cause the wire rope to fatigue. The severity of these stresses are directly related to the rope load and the D/d ratio, or the ratio of the tread diameter of the sheave or drum (D) to the diam-eter of the rope (d).

• If a wire rope is subjected to repetitive bending, small cracks will form in the surface of individual rope wires, especially at the points of contact with other wires or with the groove of a sheave or drum. With increasing number of bending cycles, the crack will grow, reducing the load brearing wire cross section.

• About The Application of Wire Rope Drum in Crane Crane wire rope drum. The main components of a crane drum set are the drum, the connecting disc and the bearing support. Process flow of the drum set. Q235B or Q345B sheet material → rolled drum and welded longitudinal welds → inspection of

• Wire rope drums are engineered and manufactured to meet the most challenging operational and safety constraints for industrial crane application. Wire rope drums can be found on typically every type of crane in a number of industrial environments. Crane drum is the component to wind wire rope in the lifting mechanism.

• Never underestimate the wire rope’s ability to cut dramatically into support and deflection sheaves, nor the sheave’s or drum’s ability to seriously damage the wire rope. Major attention must be paid to sheaves and drums in all facets of excavator maintenance. Wire rope products will break if abused, misused or overused. Consult industry recommendations and ASME Standards before using.

• Wire rope should be attached at the correct location on a flat or smooth-faced drum, so that the rope will spool evenly, with the turns lying snugly against each other in even layers. If wire rope is wound on a smooth-face drum in the wrong direction, the turns in the first layer of rope will tend to spread apart on the drum.

• Dead Wraps: The first few wraps of the wire rope around the drum (commonly known as the "dead wraps") provide a simple and secure method of anchoring the wire rope to the drum. This (anchoring) is accomplished by the friction (of the dead wraps) tightening against the drum barrel, as a load is applied.
