Sheaves & Pulleys
There are numerous advantages of a Nylatech nylon sheave or pulley over conventional steel or iron sheaves. They are lightweight at approximately 1/8th the weight of steel or iron sheaves. This improves the lifting capabilities of mobile and fixed boom cranes and eases installation. They also offer longer rope life. Nylatech monomer cast sheaves are better suited to the “on again, off again” loading typical for this application. With enhanced material memory and resiliency, the rope grooves will flex under the load of the rope providing increased support to the rope. The arm weight of telescoping cranes is decreased because Nylatech sheaves are lighter. Also, Nylatech Sheaves flex under the load of the rope increasing the contact area between the rope a nd groove, which increases load capacity. Operating costs are also decreased with lubricated grades of Nylatech cast nylon, the need for regular lubrication can be reduced or omitted. Lastly, cast nylon sheaves will not rust or corrode.
