Tipping Hoppers

Tipping hoppers are a cost effective and efficient alternative to the traditional below ground bunker.

With this system, the truck backs into the hopper to tip its load. Once the truck has driven off the hopper, the hopper is raised to the vertical position, the roof is automatically closed, to prevent the ingress of rain, and the discharge gate is opened to allow for the discharge of the coal.  See the gallery page.

Depending on the site parameters, the coal can be discharged onto a transfer conveyor or directly into a bucket elevator, for transfer to the boiler feed hopper.

The hopper is raised by two multi-stage hydraulic rams, and each ram is fitted with fail-safe valves on the discharge ports, which means that in the unlikely event of a hose being cut, the hopper will remain in the elevated position.

Coal degradation is minimal, and this results in significant improvement in the performance and efficiency of the boiler.

We have also developed a very quiet, efficient and reliable bucket elevator, which is ideally suited to an installation of this type, and recommend that you visit our bucket elevator page for more details.
