Lifting your product performance higher with engineering plastics

Read more about the benefits of using low friction, lightweight engineering polymers for lifting applications and products.

Whether it is large crane lifting materials on a construction site, a Launch & Recovery System retrieving subsea equipment in the North Sea, or even a system pulling up the curtains on a theatre stage, there are fundamental elements of mechanical lifting which are common across many industries.These being Sheaves and Pulleys.

These fundamental elements are responsible for distributing lifting weight through their close contact with the mating rope or wire.Traditionally these components would be made of steel or iron.With this would be involved a considerable amount of regular maintenance and inspection, which in turn results in increased machine downtime and less productivity.

Nylacast Engineering Plastics are the ideal solution for lifting applications and components in industry.With over four decades of experience in the design and manufacture of Nylon sheaves and pulleys, Nylacast polymers are proven to deliver a number of advantages for lifting.

Lightweight is one of these many advantages. The reduced component weight of Nylacast sheaves and pulleys allows for ease of installation and replacement (in the rare occasion is may be needed).This means that sheaves and pulleys, specifically larger diameter products, can be easily installed on site with minimum or no additional lifting equipment needed.Nylacast sheaves are typically 1/7th the weight of traditional steel sheaves.

Wear and abrasion resistance is also another significant advantage in this application.The low friction surface of Nylon sheaves and pulleys results in the reduction and often elimination of rope/wire wear.This is due to the material naturally adopting the mating rope/wire with great ease, producing a natural groove for improved lifting capabilities.

Nylacast engineering plastics are also corrosion and chemical resistant, resulting in the elimination of any maintenance, coating and painting to reduce corrosion build up.It is for this reason they are regularly utilised in offshore and arduous environments.

Overall, Nylacast sheaves and pulleys deliver increased lifting capabilities and performance whilst offering increased efficiency and running costs.Nylacast sheaves and pulleys are custom made to client needs and are available in diameters ranging from 100mm through to 3000mm and more!Furthermore, to meet specific project requirements, Nylacast sheaves can also integrate materials technology to deliver the optimum strength and advantages for both high lifting capacity and low abrasion.For example a steel inner section for increased load capacity, coupled with a low friction nylon outer grove.
