Fixed sand: when sand should freeze onto the road surface

Falköping's spreader for the method is called LTFV, which stands for Lång Tid Friktion Varmvatten (long-term friction, hot water).

Why loose sand does not last

Dry sand on ice gives friction straight away, but it lies loose. Traffic blows and throws it to the side, and before long it is gone from the wheel tracks where it is needed. Then the road has to be gritted again.

When the sand is wetted with hot water as it hits the ice, it freezes into the surface and stays put. According to Falköping, the method gives a longer-lasting treatment, better road safety, better overall economy and less impact on the environment, and the manufacturer calls it the most effective method for friction treatment of winter roads.

How the LTFV spreader heats the water

C-7 LTFV has 300 kW heating power and takes 9 minutes to heat the water to 95 °C. The spreader also has exhaust heating that preheats the gritting material.

To keep the feed even with very difficult material too, the spreader has a built-in, patented bottom agitator. Extra wear-resistant augers for extensive sand gritting and an agitator shaft for difficult material are standard equipment, together with a cover and a quick-loading system.

The versions

Falköping states 300 kW heating power and 9 minutes heating time for all versions:

• C-7 LTFV — 7.0 m³ sand/salt, 2.1 m³ liquid, 3 200 kg, one spreading disc, spreading width 2–8 m
• C-9 LTFV — 9.0 m³ sand/salt, 2.7 m³ liquid, 3 300 kg
• C-9 LTFV-2T — 9.0 m³ sand/salt, 2.7 m³ liquid, 3 500 kg, double spreading disc for airports, which according to Falköping gives even higher efficiency

More than sand

The same spreader can apply dry sand, salt, pre-wetted salt, salt slurry and salt wetted with hot water. A mixer for salt slurry is available as optional equipment, together with remote-controlled spread pattern, hydraulic disc lift, side deflectors and engine drive. LTFV is also supplied as a compact model for shorter load bed lengths.

As standard, the spreader is driven by the vehicle's hydraulics, and it can always be driven by the vehicle hydraulics even if engine drive is fitted. It is prepared for data collection, so that the treatments can be documented. See also Falköping's other disc spreaders.

Fixed sand or hot-water salting

Falköping uses the same hot water on salt in the C-7 HES. The volumes are the same, but HES has 80 kW heating power, and the C-7 HES weighs 2 200 kg.

HES is designed to make the salt work faster and over a wider temperature range. LTFV is designed to make the sand give friction for a long time.

When you contact us

Have this ready before we talk about LTFV, and we will see which version suits the vehicle:

• The truck: load bed length, and whether the compact model is an option
• Whether the spreader will run on the vehicle hydraulics or have engine drive
• Where the treatments will be carried out: road, street, footpath or airport
• Whether you will also spread salt or salt slurry with the same machine
• Whether the treatments need to be documented
