The Wellons hog fuel storage and unloading systems use a live floor design, and feature Wellons hydraulically operated super heavyduty design for high volume discharge.

The unloader assembly can be configured as a totally enclosed bin with infeed fuel delivery by roof top conveyor; or as an open bin with fuel delivery by a wheeled loader.

The following is a summary of equipment typically included with the live floor fuel bin:

  • Embedment steel
  • Transverse screw (1)
  • Rake style fuel unloading system
  • Fuel unloading hydraulic power unit and cylinders
  • Spike roll and drive with motor
  • Fuel unloader trough with unloading screw
  • Fuel bunker rake embedment steel
  • Fuel bunker inclined wall embedment steel
  • Fuel bunker cylinder anchor

The fuel bunker is sized to suit the customers requirements, for approximately 130 units it will be 40' wide by 65' long. Wall construction is by the customer.

50-feet will be used for effective storage. The other 15-feet will house the hydraulic cylinder room.

Average fuel depth varies and is evaluated to be between 15’ and 17’.

A roof structure can also be added as an option if required.
