Stoltz will be exhibiting our line of Site Spreaders at the Brazil Road Expo located at the Transamérica Expo Center in São Paulo, Brazil.

For three days the show aims to bring together the main players involved in road construction and infrastructure. Comprised of an international trade show and a highly specialized conference program, the event aims to present new solutions and methods for construction of roads and highways, highlight new equipment innovations and trends, and to promote technology transfer between exhibitors, delegates, and visitors.

Stoltz is pleased to announce that Paveline International Pty Ltd has been recently appointed the Australian and New Zealand distributor for the Stoltz range of spreaders. Paveline designs and manufactures high quality, cost effective road maintenance equipment, so distributing the Stoltz line is a natural fit.

Self contained skid mounted Portland cement and lime spreader

The two companies have already worked together to develop a 3-tonne spreader to suit work with narrow width profilers, skid steer profiling attachments, and other stabilizing machines which are commonly used in Australian road maintenance work. The small spreader is skid mounted for use on a trailer or small truck. Larger pneumatically loaded lime and cement spreaders in 15 and 25 tonne capacities are also available.

We are pleased to announce that we have added videos to our website. This is intended to give potential customers and interested persons a better idea of what we do and how the equipment performs. The videos can be found under the Resources section of the website or at this link: http://www.stoltzspreaders.com/resources/video-gallery.php.

Here is a quick guideline to getting your truck mounted Site Spreader up and running when it is equipped with the automatic controller. This can also be found in the Resources section of our website here: http://www.stoltzspreaders.com/resources/science-best-practices.php.

Filling The Spreader:

-Close the rear gate
-Close the butterfly valve on the bottom of the filter can (if equipped) or open the lids over the pop up bags and pull the bags out.
-Connect the fill hose and begin to fill.
-Keep line and tanker pressure below about 8 psi.

Spreading in Automatic Mode:

-Set your desired spreading rate in pounds per square yard (kg/sq meter) in the console.
-Hold the Open Gate button until the gate gets to about 8-10 inches (200-250 mm) for a typical rate.
-Enable Auto Mode.
-Press Start. The spreading auger will turn on automatically. Note that the PTO must be engaged!
-Start driving. The drag chain will start discharging material when the truck starts moving.
-Keep an eye on the “Alarms” section of the display. If it says “OVERSPEED”, the hydraulic system cannot keep up. Select a lower gear, raise the gate, or select a lower target spread rate.
-Press Stop when done spreading.

After spreading, visually check to see if the depth of material is uniform from edge to edge. Adjust the openings in the cross auger to achieve a uniform spread pattern.

Calibrating the Spreader:

This spreader is calibrated by changing the Material Cal Number in the Auto Mode Setup screen.

-The spreading auger must be manually adjusted to achieve a level spread pattern. Do a few short test runs and adjust the openings in the auger to achieve a full width, level spread pattern.
-Place the 1 sq.yd. tarp about 30 feet in front of the spreader.
-Spread over it while in Auto Mode.
-Weigh the loaded tarp with the hanging scale.

If the application rate is not correct, change the Material Cal No. according to the following formula:

New Material Cal No. = Current Cal No. X Actual Application Rate (Amount on Tarp) / Desired Application Rate

Alternatively, if you have measured out how far you expect your load to spread, you can use the following formula:

New Material Cal No. = Current Cal No. X Expected Distance / Actual Distance Spread

Note: Decreasing the Cal No. will increase output while increasing the Cal No. will decrease output.

We are often asked what types of trucks we recommend for cement spreaders. While we don’t profess to be truck experts, we have seen a lot of different trucks over the years and have developed some guidelines to keep in mind when selecting a truck.

Very low ground speeds are important for satisfactory application rates. We recommend the greatest gear reduction available and a transmission that allows for very low ground speeds (around 2-3 mph) while maintaining high engine rpms. The slower your truck can drive, the higher your maximum application rate will be.

We like to direct mount the PTO and pump on the transmission. Front or rear mount may be available upon request. When selecting a truck, it is important to make sure that the transmission is rated for a 500 ft-lb PTO. Note that the PTO and pump from a dump bed application will probably not be adequate.

A standard Site Spreader body with 25 tons of cement will have a loaded weight of approximately 60,000 lbs. A 15 ton capacity Site Spreader hopper will have a loaded weight of approximately 40,000 lbs. Select a chassis that has sufficient payload capacity for the size spreader you want.

Certain trucks have proven to be more difficult to work with. Tilt cabs, four-wheel drives, articulating trucks, army trucks, trucks with certain MACK transmissions, 24v systems, etc., all may require special parts and installation procedures.

Articulating trucks are great for rough terrain spreaders as long as you do not require very high spread rates or are willing to make multiple passes, since they generally go fairly fast in their lowest gear. However, the many variations of hydraulic configurations utilized in their designs often make these trucks difficult for us to work with. For that reason, we ask that you work with your dealer to set up the truck so it is delivered to us with 55 gpm @ 2,500 psi continuous hydraulic flow for running the spreader. Note that some articulating trucks may require an oil cooler to achieve this. We will also need to know if the hydraulic system is open center, pressure compensated, or load sense.
