ISI Certification (BIS) for
Round Steel Wire Rope Used As Balance Ropes Mines IS 18532
BIS certification is generally voluntary, but some products, such as wire ropes, are included in a mandatory product list by the authority under Quality Control Orders (QCO) if there is any feedback from the consumers. These orders seek to protect the public interest, health, and safety. This prevents unfair trade practices and increases the consumers' trust.
Round steel wire ropes have been the backbone of mining operations for many decades. Serves various numbers of applications, such as hoisting and hauling, as balance ropes in elevators and shafts.
IS 18532 is an important specification that provides general requirements for round steel wire ropes used as balanced ropes in mines. Let’s go through the information given below to know more about the BIS certification for Round Steel Wire Rope.
Overview of Round Steel Wire Rope
IS 18532 is an Indian standard that specifies the requirements of round steel wire ropes used as balance ropes in mines. It covers the technical characteristics, construction, material, and testing procedure for ropes.
These ropes are mostly used in mining activities, particularly in vertical and inclined shaft hoisting operations. Go through the below-given table to know more about IS 18532:

Key Characteristics of IS 18532
The standard, IS 18532, includes several considerations related to round steel wire ropes - or balance ropes, as they will be referred to later in this document - including:
1. Material Selection: The balance ropes should be constructed from high-quality steel wires. The wires used to construct the ropes should possess a tensile strength and be of a design resistant to corrosion and wear. This consideration aids in prolonging the rope's working life in rigorous mining conditions.
2. Rope Design: Round steel wire ropes are generally manufactured by a stranded process made up of multiple layers of wires. The design should consider not only load balance but also strength and flexibility during performance. This also includes the consideration of dynamic forces when lifting and lowering the rope.
3. Diameter and number of wires: The wire diameter and number of wires in a strand are both considerations in strength and flexibility. The rope should not only have enough tensile strength to perform high tensile forces but also be of sufficient flexibility to resist damage during bending and winding.
4. Lay of the Rope: The lay of the rope describes the direction the wire and strands twist or lay into the rope. Depending on how the rope is going to be used, the rope will have a right lay or a left lay. The lay of the rope will affect how it resists wear and its performance when under load.
5. Breaking Strength: The minimum breaking strength of the rope is determined by IS 18532. The breaking strength is the maximum load on the rope that will cause it to break or one of the rope's components to break.
6. Flexibility and Bending Radius: The rope should be sufficiently flexible to manage winding and bending for mining operations without overstressing the rope. The bending radius is also very important as it sets the minimum bend of rope allowed without damage.
7. Corrosion Resistance: Environmental conditions in mines tend to be harsh, meaning corrosion resistance is necessary. Ropes are often subjected to water, chemicals, and other materials that can damage the material over time. IS 18532 provides information on treatments or coatings to hold corrosion and help extend the life of the rope.
Importance of BIS Certification of IS 18532
Significance of IS 18532 in Mining Operations The IS 18532 standard plays an important role in providing safety and operational efficiency in mining activities. Let’s go through some of its importance:
- Safety: The specification assures that the ropes can accommodate the extreme demands placed on them during the hoisting operation and, subsequently, minimizes rope or attachment failure or accidents within the mine.
- Operational Efficiency: Ropes manufactured according to IS 18532, utilizing appropriate design and materials, will not only result in reduced wear and tear on equipment but also contribute to energy efficiency advantages, all of which assist in operational cost reduction.
- Reliability: Compliance with IS 18532 can ensure a high level of reliability regarding the ropes' sustaining repetitive use and reasonably demanding material properties in various working conditions.
- Long Service Life: The requirements for materials and construction methods, including corrosion resistance in the specification, will yield longer service lives for the ropes and reduce the need to replace or maintain ropes.
