OEM Elevator Lifting Wire Rope Belt for Elevator Maintenance and Replacement

Product Description:

The balance wire rope (also known as tail rope) is an essential component of vertical mine hoists. Installed at the bottom of skips or cages, it counterbalances the dead weight of the main hoisting ropes. When one skip ascends and the other descends, the varying length of the main rope creates weight difference. The balance tail rope offsets this difference, so the hoisting machine only needs to overcome payload instead of the self-weight of long main ropes.

Features:

• It eliminates the variable weight difference of main ropes between ascending and descending conveyances, minimizing peak load on the hoist.
• Power consumption is reduced, and the required rated power of the hoist can be optimized.
• Smoother hoisting movement with lower dynamic impact, which improves safety of mine hoisting operation.
• Reduced alternating stress on main hoisting ropes and related components, achieving longer service cycle of the hoisting system.
• High flexibility, good torsion resistance and corrosion resistance. It can withstand continuous heavy load and harsh underground mining conditions.

Applications:

Balance wire rope (tail rope) is a critical component for vertical mine hoists, exclusively used for weight balance in mine hoisting circuits. In double-conveyance hoisting systems, when one skip/cage ascends, the main hoisting rope on this side gets shorter while the rope on the opposite side becomes longer. This generates a variable dead load. The balance tail rope installed at the bottom of conveyances counteracts such weight variation. Thanks to this balancing function, the hoisting machine only needs to handle the payload rather than the self-weight difference of main ropes. This lowers the rated power requirement of the hoist, smooths operation, lessens impact load and extends the service life of the whole hoisting set.

Main application fields:

1. Vertical shaft coal mines for raw coal lifting
2. Underground metal mines (iron, copper, gold mines) for ore and waste rock hoisting
3. Non-metal underground mines
4. Deep shaft heavy-load hoisting projects

Customization:

Balance wire rope (tail rope) for mine hoisting can be fully customized to satisfy various vertical shaft hoisting projects. Since mine conditions vary greatly from site to site, one-size-fits-all ropes cannot guarantee stable and safe operation.

Customizable items:

1. Physical specifications Diameter, linear density, finished length and minimum breaking force are configurable to match the weight balance calculation of your hoisting system.
2. Rope structure Low-torsion or non-rotating rope designs are available to prevent twisting and spinning during operation.
3. Surface treatment Bright (ungalvanized) steel wire for dry mines; hot-dip galvanized wire for mines with mine water, humidity and corrosive gas.
4. Material grade Different steel grades can be selected to achieve target tensile strength, fatigue resistance and wear performance.
5. Auxiliary service Custom marking, special winding & packaging, inspection test reports can be supplied together with goods.

Packing and Shipping:

Balance wire rope (mine tail rope) is carefully packaged to avoid damage during long-distance transportation, loading, unloading and underground handling.

• Wound onto sturdy steel or wooden reels, suitable for crane lifting.
• Protected with inner plastic wrapping and outer waterproof covering to keep out moisture, dust and rain.
• Each reel is clearly marked with rope specifications, diameter, length, weight, batch number and inspection info.
• Secure binding prevents loose unwinding during transit.
• Custom packaging options are available upon customer request, such as special export packaging for sea shipment.
