Variant In-line Loading Chute (Super Heavy Duty)

The Variant In-Line Loading Chute (Super Heavy Duty) is step forward in the evolution of In-Line Loading Systems. It is specifically designed for high tonnage ore passes where a chute is expected to last many years.Increased Durability

The chute is a extremely ruggedly built, with heavy reinforcement on all sidewalls, lip walls, lip floor and pin connections. The lip pins are brass bushed and pinned, providing a zero-radius hinge— with no hinge crush point.

The rockbox is designed to be cast directly into concrete—not simply anchored. This provides additional rock-box reinforcement in the area that it’s most needed. All liners are lapped over bolted joints, and bolted joints are all perpendicular to the muck flow.

Improved Safety

The Super Heavy Duty Chute is designed from the ground-up with a failsafe hydraulic system. It includes side-mounted gate and lip cylinders, providing much safer maintenance access than traditional chute designs.

Simplified Maintenance

The sidewall-mounted cylinder configuration eliminates the entire headblock assembly—a high maintenance area in traditional chute designs. The traditional sidewall extension plates are replaced by heavy sidewall extension liners which fit inside the main lip sidewalls. The provides better maintenance access, and eliminates a narrow bolted connection.

Available Options

  • Sidewall access doors (blast doors)
  • Wide variety of access platforms
  • Lip configurations for loading rail cars or haulage trucks
  • Air cannon
  • PLC-based controls or relay-based controls
  • Additional control inputs/outputs for handshaking withaccess gates, level monitoring, or other mine systems
  • Fully enclosed hydraulics systems, including integratedcooling systems
  • Pedestal, pendant, and/or infrared remote control withchute/chute interchangeable remotes.

Sizes

Chutes are available in the following sizes:

  • 4′ x 6′
  • 4′ x 8′
  • 6′ x 8′
