Quality Engineered Construction Equipment Made in the USA
We would like to thank our friends at Asphalt Solutions for the opportunity to build a pretty unique 650. First they wanted it to be all black, next they wanted a custom extension on the hopper, finally they wanted a light kit so night time curbing. Here are some pics of the final product.
The hydraulic braking system is activated with a motorcycle type hand lever. It also features a locking mechanism that serves as a parking brake. When the lever is activated, hydraulic fluid flows to two calipers each located on the front forks. Brake pads in the calipers apply friction to each 3/16” thick x 7” dia disks which are directly attached to the axles thus braking all four front wheels. The primary use of the brake is to prevent the curb extruder from rolling when extruding down hill.
Here are pictures of some curb that was installed with one of our machines. This is a commercial curb with a decorative appeal. The customer used smaller stone (a lot of it), laid the curb and then came back a few hours later and used a pressure washer to expose the stone. If you are interested in this process, please contact Hank.
Here is a situation where the customer needs to extrude over an 18″ wide trench with a 3″ high pin. This machine was designed to extrude a curb that is 12″ L, 10″ H and has a 6″ flat spot on top of it. In order to do this we had to move the front over 17.25″ from it standard position (Pic #1). We had to add an outrigger arm to provide stability to the machine since the front end was moved over so far. The next pic shows the remaining 6″ of the trench that needs to be exposed per the job requirement.
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.
Optional Removable Hopper Side Plates are now a new feature which any new machine will accommodate. This option allows an operator to remove the side panel from the hopper for wheel barrow access or ease of shoveling. Easy replacement of the hopper panel increases hopper capacity and allows for overhead loading as from a truck bed or front loader. (No tools are required for removal/replacement)
The Swivel Rear Wheel option facilitates removal of the curb extruding machine at a job’s conclusion. Situations such as obstructions or lack of base for machine travel do—at times—require physically lifting the machine (sometimes with a loaded hopper) off the curb. With the Swivel Rear Wheel, the operator can avoid this difficulty; by rotating the tail wheel 90 degrees, turning the front wheels 90 degrees in the same direction, and elevating (cranking up) the machine, the curb extruder can be easily pushed sideways off the curb.
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 now offers an 8” Cast Auger (much like our 6” cast auger). This 8” Cast Auger is made from white iron resulting in a homogeneous material makeup; thus the hardness of material is consistent throughout. This improves upon the original design of the fabricated auger which was simply hard-faced on the outer surfaces. In addition, durability is also improved in wear surface area: This new cast auger is 9” long, and 2 are required to replace the original 18” long fabricated one; consequently, there are now 4 wear surfaces as opposed to only 2.
Proper, safe, and level lifting of the Miller Curb Extruding machine is now easy with our new Single-point Lifting Lug. This optional feature enables the use of an overhead crane, forklift with lifting boom, cherry picker, or any other appropriately rated lifting machine to safely and easily lift/transport (with an empty hopper) the curb extruding machine.

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.
