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.

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.
