We are commited to

Innovation :

Our cutting-edge technology revolutionizes the elevator industry, delivering enhanced safety, durability, and performance. Our wire ropes are meticulously engineered to withstand rigorous stress and ensure smooth and reliable operation. With state-of-the-art materials and advanced manufacturing techniques, we offer unparalleled strength and flexibility, minimizing wear and tear.

Quality :

We maintain stringent quality control measures throughout our manufacturing process, ensuring that each rope leaving our facilities adheres to the highest industry standards. Best quality of input materias are ensured by sourcing from world’s leading manufacturers and stringent in-house quality testing facility which lead to the superior quality products for use in elevators.

Sustainability :

 We are dedicated to environmental sustainability, integrating eco-friendly practices into our operations. Our ropes are designed for energy efficiency, reducing power consumption and minimizing our carbon footprint. We aim to contribute to a greener future for generations to come.

Bending Fatigue Appraisal :

Bend fatigue resistance is the ability of the wire rope to withstand repeated bending over drum/pulley under constant or fluctuating load. Our ropes undergo a comprehensive fatigue testing program. which has been devised not only to ensure that our ropes consistently deliver performance but also to provide information for product improvement and development.

Wire rope construction

Strand Construction

Seale (S) 1-9-9

The thicker wires of the outer strand layer provide greater wear resitance. Rope with such strands are mainly used when the rope service life is more strongly impacted by abrasion than by rope fatigue due to bending.

Warrington (W) 1-6-6-6

With its more, thinner outer wires the warrington construction is more flexible and better resists fatigue bending than the seale construction. Ropes with such strands are often used where the service life of the rope is strongly influenced by fatigue due to bending and smaller sheves than by abrasion of the outer wires.

Filler (F) 1-4-4-8 or 1-5-5-10

This construction employs the advantages of both priormentioned strand types. It has more thinner wires for flexibility, a higher metallic cross section for greater breaking stregnth and thicker outer wires to fight against abrasion. Ropes with such strands are being used in high-rise/high-speed elevators which demand the most in the areas of elongation, round cross-section, flexiblity, fatigue resitance and breaking stregnth.

Direction and type of lay

Direction of lay

The direction of lay for the strands is the direction of the helix of the wires within the strands.
The direction of lay for the rope is the direction of the helix of the outer strands within the rope.

Type of lay

Regular lay : The wires in the outer strands have the opposite direction of the outer strands in the rope.
Land lay : The wires in the outer strands have the same direction as the outer strands in the rope.
