BRUKS Radial Stacker


BRUKS Radial Stacker

The BRUKS Radial Stacker is fully automated and allows for safe, easy and efficient stacking of material into organized storage piles. The Radial Stacker can be designed to meet the customer’s pile size and storage requirements. The Radial Stacker offers many features such as luffing and shuttling.

  • Capable of providing controlled material storage
  • Very high capacity receiving for unloading rail cars, trucks, barges or other processes
  • Provides customers with the ultimate flexibly for storing a variety of materials
  • Proven reliability and long service life
  • Fully automated designs


BRUKS Radial Stacker

The BRUKS Radial Stacker reduces the space needed to store volumes of materials by organizing the process into a semi-circular pile arrangement. Rather than pushing materials around with dozers, the piles can be arranged so that the oldest materials are reclaimed first, are not trapped at the bottom of the pile and are reclaimed last. To some extent, blending can occur during the stacking phase, reducing variability in the pile.

The BRUKS Radial Stacker can be of various lengths to suit the application. It can luff, or be raised or lowered, to reduce the fall distance from the head pulley to the building pile, to reduce wind effects during stacking. The conveyor can have a telescopic feature, so that a pile with a broad top can be formed, increasing the pile storage volume.

The centreline of the infeed conveyor would be located at the level of the line that crosses the drawing a the top. The feed chute would terminate in a large bearing that would allow the stacker structure to carry the head section weight. A chute would pass the chips to the feed section of the stacker and onto the belt.

The stacker would slew in an arc, to create the pile. It has the capability to slew to 270 degrees and more, but the layout may limit it to 180 degrees, and possibly less. A slew bearing is located just above the control house and support legs. (3) 7.5 HP motors drive the slew drive gearboxes.

In the stacker shown there is a pivot bearing shown just above the A-frame support steel

that allows the entire structure to luff up and down. When first building the pile it would stack out chips at a 15 degree down angle, with tilt switches monitoring the pile development. As necessary the boom would slew to the right and left, and lift as the pile height required it. The angle of the boom would increase and eventually be limited to a 10 degree up angle to build the pie height at 60 feet. It is possible for the boom to raise to 15 degrees if needed, to clear a stacked pile or for rapid relocation of the boom around the pile.

As an option, this boom can be fit with a leveling screw located below the head pulley of the boom (shown in this drawing). This screw allows the pile to build a broad flat top, adding significantly to the storage volume of the pile. BRUKS would propose the use of a 20’ long screw here. The weight and operation of the screw would not very much to the overall weight of the boom and counter-weight. It is listed as an option for your consideration.

Please note that there is no operator’s cabin on this machine. It operates automatically in response to the positions of the lateral tilt switches.
