Engineering Plastic Components for Heavy Equipment and Cranes
We offer engineering plastic components for heavy equipment cranes and equipment. Our products are designed to replace traditional metal parts with lightweight, wear-resistant, and low-maintenance solutions. Diode Trading EST offers products that are ideal for service providers, crane rental companies, and heavy equipment operators. Our products are ideal for operators working in harsh environments, including sand, dust, high temperatures, and corrosive conditions. Our products are manufactured from top-notch engineered plastics.
Telescopic Boom Wear Pads and Boom Liners
We offer sliding components installed between boom sections of mobile and hydraulic cranes that are known as telescopic boom wear pads and liners. Our products are made up of durable, high-performance cast nylon and other low-friction engineering plastics. Our rear pads help the boom extend smoothly while minimizing stick-slip movement. The telescopic boom bear pads and liners are a popular, reliable aftermarket alternative to OEM crane wear pads.
Advantages
- Controlled and smooth boom movement
- Steel-to-steel contact and reduced friction
- Dust-resistant, resistant to high temperatures and sand
- Custom machining available to drawing or sample
Polymer Crane Pulleys
Polymer Crane Pulleys are also known as crane sheaves or rope wheels. The rope wheels are used in crane boom heads, hoisting systems, and lift assemblies to guide and support wire ropes. Manufactured from cast nylon and oil-filled engineering polymer grades, these crane pulleys are a lightweight and corrosion-resistant alternative to traditional steel pulleys.
Polymer crane pulleys significantly reduce wire-rope wear, operate with lower noise and vibration, and require minimal maintenance. These crane pulleys works perfectly for cranes operating in desert, coastal, and industrial environments where corrosion and abrasive dust are common.
Key Advantages
- Extended wire-rope service life
- Quiet Operation
- Lightweight
- Weather and corrosion-resistant
- Custom groove profiles available
Cable, Rope & Hose Guide Fairleads/Rollers
Cable, hose guide rollers, rope, and fairleads are essential protective components that guide wire ropes and hydraulic hoses along crane booms and moving structures. Our cables are manufactured from UHMWPE, nylon, or polyurethane. These rollers prevent abrasion, snagging, and premature cable failures. Cables and ropes components are critical in high-temperature and sandy conditions.
Advantages
- Eliminates maintenance costs
- Resistant to impact and wear
- Protects hydraulic hoses and wire ropes
- Ideal for replacement applications
Plain Bearings & Plastic Bushings
Plastic bushings and plain bearings (heavy-duty) are mostly used in articulation points, crane pivot joints, and structural linkages. These plastic bushings are crafted from PTFE composites, cast nylon, and acetal (POM). These bushings provide grease-free operation, corrosion resistance, and load distribution.
Engineering plastic bushings are ideal and works the best in dusty and abrasive conditions. These bushings significantly reduce maintenance requirements compared with traditional bronze or steel bushings.
Key Advantages
- Maintenance-free and self-lubricating
- Dust and corrosion-resistant
- Long service life
- Available in standard and customized
