Features and Benefits
Features and Benefits
- High-Tensile Almag Alloy Frame
Constructed from lightweight yet durable almag alloy. Provides high strength-to-weight ratio, ensuring long service life without adding unnecessary load to the system. - Precision Ball Bearings in Nylon-Reinforced Wheels
1.8" nylon glass-reinforced wheels with permanently sealed precision ball bearings. Delivers smooth, quiet, and maintenance-free operation, ideal for continuous-duty environments - Dielectric Insulation
All trolleys are dielectrically insulated. Enhances electrical safety when used with power cables, reducing the risk of shorts or arcing. - Low Inertia Design
Inertia is less than 1% of the load. Minimizes resistance to motion, improving energy efficiency and responsiveness of the crane system. - Wide Operating Temperature Range
Operates reliably from +32°F to +212°F (0°C to 100°C). Suitable for a broad range of industrial environments, including high-heat or temperature-variable settings.
Optional Features
- Saddle Types Accommodates different cable or hose types and diameters, ensuring secure and organized routing. Saddle types include Small Saddle, Large Saddle, Flatwire Saddle, UII Saddle, and 12" Saddle.
- Sling Trolleys Ideal for supporting heavier or bundled cables and hoses with flexible suspension. Small Sling and Large Sling Trolleys available.
- Cable Trolley Variants Cable Trolleys with Small, Large, or Flatwire Saddles. Tailored for specific cable geometries, improving cable life and system performance.
- Festoon Slider A low-friction sliding support for cable management. Provides a cost-effective alternative to wheeled trolleys in short-run or low-duty applications.
FAQs
FAQs
What track sizes are compatible with the Unified Festoon Trolley?
The trolley is designed for use with Unified enclosed track systems, specifically sizes 3, 4, and 8. This ensures compatibility across a wide range of crane capacities and layouts.
What types of cables or hoses can the trolley support?
The trolley can accommodate both round and flat cables, as well as pneumatic or hydraulic hoses, depending on the saddle or sling configuration selected. Optional saddles include small, large, flatwire, and 12" variants.
What is the load capacity of each trolley?
Each trolley is engineered to support typical festoon loads, with specific capacities depending on the saddle type and cable configuration. For precise load ratings, consult the product’s technical documentation or request a load chart.
Are the wheels suitable for high-cycle or continuous-duty applications?
Yes. The trolleys use 1.8" nylon glass-reinforced wheels with sealed precision ball bearings, designed for smooth, quiet, and maintenance-free operation in high-cycle environments.
Can the system be used in electrically sensitive environments?
Yes. All Unified Festoon Trolleys are dielectrically insulated, making them suitable for applications where electrical isolation is critical, such as systems carrying power cables or operating near sensitive equipment.
