The MC 900 dual auger machine is equipped with a dual auger housing designed to extrude either a 18″ or 24″ curb and gutter. This machine is built with 2 augers next to each other (see picture) in a housing specially made for our dual auger machines. If you would like to do a 24″ curb and gutter (CFD-1887), the machine is equipped with 2 – 8″ auger housing. If you would like to do a 18″ curb and gutter (CFD-1886) the machine is equipped with 1 – 8″ auger and 1 – 6″ auger housing. Either machine also comes with vibration and 2 outrigger arms to provide stability (machine width is 56.25″).
*please note, this machine does not have any capabilities to change the grade. Any imperfection in the grade will result in the curb having the same imperfections.
Typically this custom machine will be around $25,000 and will require a 4-6 week lead time.
In order to extrude curb over pins a special curbform is required. It requires the curb height to be at least 5″ greater than the pin height. For example, if the pin height is 2″, the curb needs to be at least 7″ high. The additional height allows for the centerline of the auger to be raised to clear the pins while extruding and allow for sufficient free flow of material through the form. The front of the form has an opening to allow the operator to steer the form directly over the pin. The opening has rubber flaps to allow the pin to enter the form but restrict material from exiting the form.
The Tail Wheel Outrigger option allows an operator to stabilize the curb extruder for a variety of job conditions. If a front wheel assembly is offset to accommodate rebar; if a wide curb is being extruded and the tail wheel is moved severely off-center, or if curb is being laid in a trench—the Tail Wheel Outrigger will provide stabilization for the curb extruding machine. Note: Tail Wheel Outrigger needs to run on a compact base as does the standard wheels.
The Cast Compaction Tube option allows for extended compaction tube life. The Cast Compaction Tube is made from white iron, and—unlike the fabricated compaction tube—is homogeneous in material makeup and therefore uniform in hardness throughout.
We are able to do limited trench curbing by use of special built auger housings, compaction tubes, and forms. In this situation the entire auger housing, compaction tube and curb form are lowered into the trench. On the pictures below you will notice how the auger housing has an extension on it so it can be lowered into the trench. There are some limitations, however; consult the factory for your trench curb requirements.
Miller Curber has recently upgraded the throttle control for all Curber models utilizing the 13 Hp Honda engine. The new throttle control consists of a “tension adjustable” lever action control connected to a flexible cable assembly. The cable assembly consists of a stainless steel braided cable and sheath. The sheath is externally coated for weather resistance and lined with a friction resistant core for ease of operation.
