Every rope manufactured by Brunton Shaw UK will satisfy the Loadrite strength testing requirement. This means that a sample from each production length is tested to destruction and must either equal or exceed the published minimum breaking load.

Brunton Shaw UK ensure correct and consistent diameter dur-ing manufacture by applying the rigorous Sizerite regime of diameter measurement throughout the production process.

Luberite ensures that during manufacture Brunton Shaw UK ropes are fully impregnated with a controlled amount of high performance lubricant designed to minimize corrosion and maximize rope life. The quality of lubricant for traction drive ropes is carefully controlled to prevent slip.

Brunton Shaw UK routinely conduct endurance fatigue testing on samples of rope to ensure optimal and consistent performance.

Performance, Installation, Maintenance and Discard

BSUK Elevator ropes are manufactured in accordance with BS EN ISO 12385:Part 5 ‘Stranded ropes for lifts’ and ISO 4344 ‘Steel wire rope for lifts’, they are suitable for suspension duty on traction drive and roped hydraulic lifts and also for compensating and governor duties.

QUALITY ASSURANCE

BSUK is registered to the International quality standard ISO 9001 and is an Approved Supplier to a leading Elevator manufacturer.

BSUK apply strict standards of control to all elements of production from material selection to final testing. Elevator rope diameter tolerances need to be less than other types of ropes in order to ensure correct contact between the rope and groove. Throughout the entire production process BSUK ropes are closely monitored to ensure the tolerances are met and the diameter is consistent.

Routine and regular testing of rope samples from manufacturing runs for fatigue endurance, elongation characteristics and diameter stability is carried out on a dedicated fatigue test facility to ensure consistent rope performance.

Drums, Sheaves and Pulleys

These should be cast iron or steel and have smoothly finished machined grooves with rounded edges.Regular inspection of grooves and pulleys and examination of ropes for correct relative contact andwear is of the utmost importance, especially in the face of ever-increasing shaft speeds.

Minimum Drum/Pulley DiametersThe ratio between the pitch diameter of sheaves, pulleys or drums and the nominal diameter of the rope, irrespective of the number of strands, shall be as follows:-

Discard Criteria for Lift Ropes

This table indicates the maximum number of visible broken wires in the worst section of rope that can be allowed, taken over one complete lay length or approximately 6 rope diameters.

Discard should not only be determined by wire breaks, other factors such as irregular wear patterns, excessive stretch, reduction in diameter, localised damage corrosion etc. must be taken into account by the competent person when making a thorough examination. Note that a rope with a diameter reduction of 6% or more of the nominal diameter should be replaced immediately. For further information refer to ISO 4344, BS EN 12385 or contact our Field Services Department.

Care and Maintenance of Elevator Ropes

Before ropes are installed the sheave grooves should be checked for wear. Worn grooves cause rope damage. This precaution is especially important when worn ropes are being replaced as the grooves may have become worn by the old ropes to a size which is too small to adequately accommodate the new rope. All the ropes on an installation should be equally tensioned, BSUK recommends tensioning between ropes of ± 10%. Unequal tensions result in unequal wear, slipping and premature rope failure. In a new installation, all foreign matter, stone, dust, cement etc should be removed before the ropes are installed.

Lubrication is critical in achieving optimum rope performance, it reduces friction between component parts of the rope, slows the onset of fatigue and helps prevent ’rouging’, however, too little and rope life can be reduced, too much and slip may develop. All BSUK lift ropes are lubricated during manufacture to ensure they contain the correct type and quantity of lubricant for the application. The quantity of lubricant for traction drive ropes is carefully controlled to prevent slip.

Depending on the conditions under which the rope is operating however the lubricant applied during manufacture may not last the life of the rope. Periodic lubrication may therefore be necessary however care should be taken to ensure that the coefficient of friction is not reduced below the value at which slip will occur. Excessive amounts of lubricant should be avoided. Before re-lubricating the rope should be cleaned to remove any debris and contaminated lubricant. After re-lubricating BSUK recommends that rope tensions are checked and adjusted where necessary.
