Commercial Curbilders

PRODUCT OVERVIEW
For over fifty years the Miller MC Series Curbilders have offered unequaled performance and versatility for the placement of free- standing curb. These simple and efficient self-propelled machines operate on the extrusion principle and provide the most economical means available of constructing small to mid-sized continuous curb from either concrete or asphalt. This quick and efficient process drastically reduces the high labor costs associated with hand formed and poured curb and produces high quality, extremely dense curb at a rate of up to 15 fpm (up to 30 fpm for MC900). Miller’s exclusive interchangeable extrusion auger assemblies give each Curbilder the capacity to extrude more shapes and sizes than any machine in its class, from 3-1/2” to 18” high curb. A wide variety of options allow these machines to meet the toughest specification work.

	MC 550/650 The MC 550/650 Curb Machines are the bread and butter of all the models we make. They are very versatile curb machines that are designed to handle everything from extruding curb in a parking lot, trench curb, barn curb or curbing along a city street, county road or highway. The only difference between the 2 models is the 550 has a 13 HP Honda recoil start engine and the 650 has a 13 HP Honda electric start engine.
	MC 655  This machine has an auger housing that is offset by 12″ to allow the MC 655 Curb Machine to extrude curb under an existing guardrail.
	MC 750  The MC 750 Curb Machine has an auger housing on both the right and left side and is designed for the customer who wants to be able to switch from a left hand extrusion to right hand extrusion quickly while at the job-site. Keep in mind for this curb machine you will need 2 curb forms (one for the right and one for the left) if the curb is asymmetrical.
	MC 850  This machine is designed for the customer who has large concrete curbs ( typically taller than 13″) they need to extrude. The MC 850 Curb Machine has a tubular frame, a 20 HP 2 Cylinder Honda Engine, a heavy duty clutch, 2.5″ diameter wheels, heavy duty forks, heavy duty auger housing and a heavy duty motor mount.
	MC 900  The MC 900 Curb Machine is designed for the customer who has miles and miles of roadway curbing projects or has very large (typically 13″ or taller) concrete curbs they want to extrude With 3 sections of augers (all other models only have 2) in it, the 900 is the longest and fastest machine we make, making it ideal for miles and miles of roadway curbing projects.
	Curb and Gutter Machine  This machine is designed to extrude either a 18″ or 24″ curb and gutter. This machine is built with 2 auger housings next to each other. If you would like to do a 24″ curb and gutter (CFD-1887), the machine is equipped with a 2-8″ auger housings. If you would like to do a 18″ curb and gutter (CFD-1886) the machine is equipped with 1-8” auger housing and 1-6″ auger housing. This machine is the same length as our MC 900, but is 56.25″ in width. This machine requires a graded, compacted base that is at least 56.25″ in width. Either machine comes with vibration and 2 outrigger arms to provide stability. 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.

Curb Mix Information 

BECAUSE AVAILABLE MIX AND JOB CONDITIONS WILL VARY FROM ONE AREA TO ANOTHER, THE FOLLOWING CONCRETE AND ASPHALT MIX SPECIFICATIONS CAN BE USED AS GUIDES FROM WHICH TO DETERMINE EXACT MIX REQUIREMENTS:

Aggregate/Sand Information:

The size of stone and the amount of stone in the mix is very important. It is the stone that the auger pushes. A mix that has stone of a large enough size and quantity, will move through the Curber easier and quicker than a mix that does not. A mix with the proper size and quantity of stone puts less stress on the drive system and the wear components. Recommended minimum size of stone is 3/8 inch. The larger the curb size, the larger the stone should be and the more stone there should be. Maximum stone size is 3/4 inch.

The larger the stone and the more stone there is in the mix, the more finish work may be required. But, the larger the stone and the more stone there is in the mix, the easier and faster the mix will move through the Curber. The easier the mix moves through the Curber, the longer the wear life of the wear components. As the content of stone is increased the content of sand should be equally decreased. Typically a blend of Sand 60 percent and Stone 40 percent is a good starting point. A mix that has stone of too small a size and quantity, and or a high sand content, WILL PACK rather than move through the Curber. With this kind of mix the auger will spin many more times to move the mix. This extra spinning will cause excessive wear to all of the wear components. This kind of mix can wear out an auger, compaction tube, or curb form within 1500 to 2000 lineal feet of curb. This kind of mix will also cause the Curber to move very slow or not at all.

Minimum stone size 3/8 inch	Maximum stone size 3/4 inch

Recommended Mix Specifications:

CONCRETE CURB 
For one cubic yard of concrete:

• 0 inch to 1 inch slump
• Cement: 660# (7 sacks)
• Sand: 1,600 #, 5 percent moisture
• Aggregate: 1,400 #, 3/8 inch
• Water: Approximately 15 gallons 

Keep loads to 3 yards when possible. Water content varies according to materials and moisture content. Larger loads and higher air temperatures may require more water to maintain slump. Add water at job site only. Work materials to dry side. Retardant should be used at the manufacturers recommended minimum amount. This amount may be adjusted based on local conditions. Air entrainment should be added at approximately 5 percent. This amount may be adjusted based on local conditions.

ASPHALT CURB
PRODUCT WEIGHT PER TON PERCENTAGE 3/8 inch Stone 590 29.50 percent Washed Sand 1250 62.50 percent Liquid Asphalt 160 8 percent

Aggregate should be thoroughly washed and dried. Virgin mix is recommended. Liquid asphalt content by weight for virgin mix should be 8 percent. If using recycled mix and the curb does not stand the liquid asphalt content will need to be raised. Recycled mix usually has too many foreign substances in it and it usually does not have enough liquid asphalt in it. The liquid asphalt content may also have to be raised if the mix has slag, unwashed aggregate, or other absorptive materials in it. Working temperature – 200 to 270 degrees Fahrenheit.

USE THE FOLLOWING CALCULATIONS TO HELP DETERMINE THE QUANTITY OF MIX REQUIRED FOR ANY GIVEN CURB FORM:

ASPHALT: 

• 1,920 ÷ cross sectional area of the curb form = lineal feet per ton
• Cross sectional area of the curb (in square inches)

CONCRETE: 

• 3,888 ÷ cross sectional area of the curb form = lineal feet per ton
• Cross sectional area of the curb (in square inches)

NOTE: 

1. See Choosing the Appropriate Auger Size info sheet to determine the square inch area of the curb form.
2. Refer to Curb Form Design Sheets for Curb Shapes and Data.

Choosing the Appropriate Auger Size 

Miller Curbers can be equipped with one of four (4) different extrusion auger diameters.

These diameters are 5 inch, 6 inch, 8 inch and 10 inch. 

Auger assemblies are interchangeable between all Miller Curber models with the exception of the 10 inch diameter assembly which is only available on the higher horsepower models Mc850 and MC900.

Each of these auger assemblies works best with a particular range of curb sizes, measured in cross sectional area. The relationship between the cross sectional area of the curb and auger size is critical and must be given careful consideration when matching a particular curb with the correct auger assembly.

IMPROPER SIZING CAN CAUSE EXCESSIVE COMPONENT WEAR, REDUCED LIFE, POOR PERFORMANCE OR COMPLETE FAILURE TO OPERATE.

The following table is a general guide to choose the correct auger assembly for your application. Always consult the factory for curb form and auger size recommendations. Some curb shapes may require deviation from this chart.

Because most extruded curb is between 33 and 55 square inches in cross sectional area 90 percent of all machines are equipped with the standard 6 inch diameter auger.

The most common mistake when sizing forms and augers is choosing a curb form which is too small for a particular auger size.

 For example, a curb shape that is a simple rectangle 6 inch wide x 4 inch high would have a cross sectional area of 24 square inches. This puts it clearly in the 5 inch diameter auger range.

Attempting to do this shape with a 6 inch auger would result in a number of problems. The amount of material discharged by the 6 inch auger into the form would be so great in relation to the cross sectional area of the curb that the machine would not be able to discharge, or extrude, the material fast enough. In effect, the mold becomes a severe bottleneck. As a result, excessive pressure would be created in the form. When the density of the material in the form reached the point where it could be compacted no further the excessive pressure in the form would cause the machine to actually lift, allowing material to squeeze out from under all sides of the form. This would reduce the pressure in the form but not produce an acceptable curb. Excessive pressure may also be transmitted back through the drive train causing repeated disengagement of the safety torque arm and/or shear bolt breakage. To remedy this problem, auger diameter must be reduced or curb area increased.

The second most common mistake when sizing forms and augers is choosing a form that is too large for a particular auger size. Under sizing the auger will not cause problems as severe as over sizing but will affect machine performance. Curb density and finish may be adversely affected and extrusion speed will be reduced. It is possible to add 5-10 percent to the recommended upper limit for any given auger size and still extrude satisfactorily. In the most severe case of an undersized auger the machine may discharge enough material into the form to propel itself, but inadequate density may result in a loose curb with open finish and surface voids that may not stand. Always consult the factory for recommendations on proper auger size and curb form choices.

Auger assemblies can be provided as either hollow, allowing 3/8 inch diameter reinforcing rod to be fed through the hollow auger shaft and placed in the finished curb, or as solid. The primary difference in these systems is that the in the hollow the augers are installed on a tubular shaft that is 1-1/4 inch OD by 3/4 inch ID allowing the reinforcing rod to pass through. The solid system uses a 1-1/4 inch diameter solid shaft.

The auger assembly can be placed on either the right or left side of the machine. The machine’s right and left are determined by standing at the end of the machine where the curb form is attached and looking at the open end of the form. From this perspective, if the form and auger assembly are on the left then this would be considered left hand extrusion. Unless otherwise specified at the time of ordering all machines

These different options for your Miller Curber Commercial Curbilder are available.

Your Choice of Hopper: 

Included in the purchase of your machine you get to select one of the 2 hopper configurations. The machines are built so they can extrude a curb on either the LEFT or RIGHT side of the machine.

Left Side Extrusion	Right Side Extrusion

If you would like to extrude on either side, then you would need the reversible hopper.

If you only plan to Extrude on the LEFT hand side (Right and Left is determined by watching the machine work away from you). You could select the wheelbarrow hopper. This hopper can hold more material and has a larger cut out so you can easily dump a load of material into the hopper with a wheelbarrow.

With either hopper choice you could have an optional removable hopper side plate. This plate pins into one side of the hopper and when it is in all 4 sides of the hopper are the same size. Some customers like this when they load from a cement truck because it reduces the amount of mix that can get spilled from the hopper.

Wheelbarrow Hopper	Removable Side Plate
	(Rebar inserted into Hollow Auger Shaft)
Lifting Lug  This is a single point that you can lift the machine from	Hollow Auger  This will allow you to pass rebar from the machine into your curb. If you would like a hollow augers instead of the standard solid auger

	Cast Compaction Tube This compaction tube is made from the same material as the augers. So it’s a white iron compaction tube. This compaction tube will last 15 times as long as a steel compaction tube that comes with the machine. If you would like the cast compaction tube
	Rear Swivel Wheel This option is designed so that if you are curbing back to a solid object, like a building, that you can get the machine as close to the building as you can before you get the machine off the curb. In the past guys would lift the machine off the curb. This option allows you to raise the machine up, rotate the wheels and push the machine off the curb
	Vibration Kit This can be added to any machine to assist in getting concrete into the augers to keep the augers full, please consult us to make sure this option will work in your application and machine.
	Hydraulic Breaking System 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” diameter 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. Currently available with machines with solid wheels
Pneumatic Tires: if you would like pneumatic tires in lieu of solid tires
