Maximum safety – Mounting and demount systems

The key components and sturdy construction of the Stratos spreaders are designed for maximum safety and stability, especially during mounting and demounting.

The Stratos spreaders are available in two basic variants:

• For demount legs, hooklifts and fix-mounted systems
• For the ro-ro (roll on/roll off) system.

Both variants can be demounted with a full hopper and full brine tanks.

The new ro-ro system – Even better and easier to use

The further development of the ro-ro system enabled us to make efficient improvements in trailer operation, as the 40cm increase in clearance permits the use of a trailer or a mobile warning sign. In addition, the small tipping angle and the safety belt provide maximum safety while mounting and demounting.

Conveyor belt system

The Stratos systems combine efficiency with safety; the conveyor belt system provides a reliable means of practical every day applications. The integrated conveyor belt is fibre-reinforced, and its V-profile ensures even transportation of the spreading material, while a stainless steel guide plate makes it possible for the belt to glide at full surface contact and minimum friction.

The precise dosage of all commercially available spreading materials is enabled by the accurately adjustable belt speed as well as a feed gate. The feed gate is equipped with an integrated lump-crushing function to ensure a flawless spreading operation; lumps are broken up at constant pressure, preventing stones and foreign particles from blocking or damaging the system. The constant feed rate allows for high dosing accuracy, irrespective of the spreading material’s moisture content, while fitted chains ensure the controlled delivery of the spreading material to the chute. The optimised belt cleaning system prevents salt from running onto the truck’s loading platform, improving the vehicle's ease of maintenance. The lateral sealing between the hopper and the conveyor belt by vertical belt wipers adds to the simplified maintenance required. 

Auger system

The basic component of the Stratos auger system is a Flex auger with two-stage pitch. It is a cold-formed spiral with an open structure that allows for effort-saving transport at low breakaway torque. A variable thread ensures even discharge of the hopper, having a direct positive effect on the centre of gravity of the truck’s spreader. Our new dosing disc achieves even dosage, which is guaranteed by a closed-loop control circuit. Meanwhile, continuous target-to-actual comparisons ensure accurate and constant speed of the system. A cover fitted as standard relieves the auger of the spreading material’s load, noticeably increasing its service life. The auger system is driven by a high-torque hydraulic motor and ensures safe and reliable start-up.

The Stratos pre-wet equipment is accurately adapted to the hopper size, the capacity of which has been increased, permitting an individually adjustable pre-wet salt admixture of FS 25 to FS 35. The laterally situated liquid tanks with integrated baffles are made of impact-proof and cold-resistant polyethylene. The point of intake is located at the centre of the tank, which permits trouble-free operation even in challenging hilly or mountainous regions. The integrated level indicator enables drivers to always keep track of the spreading material consumption, while the stainless steel filling and drain connection ensures reliable filling, which is considerably accelerated due to the integrated valve-filter combination, large duct cross-sections and maximum user friendliness. When switching on the brine (FS 30), the dry material is automatically reduced and the distribution system settings are optimised in accordance with the change in composition of the de-icing agent. The system achieves a high level of accuracy, thanks to integrated sensors for comparison of the actual versus the target value of the control loops.

Premium distribution system

In order to apply the spreading material as efficiently as possible, we have advanced our distribution systems to achieve the best possible material flow by integrating a PE chute and optimising the outlet angle of our mixing system. This is enabled due to the path of the spreading material, which is transported via the Premium mixing system to the centre of the spreading disc and is optimally distributed until it is discharged. As a result, a homogenous mixture is produced, which is ejected dynamically as a concentrated jet against the direction of travel.

Premium^plus distribution system

The Stratos Premium^plus mixing system is a further development of our Premium mixing system. In the plus variant, the mixture of salt and brine is completely prepared in a mixing chamber by means of centrifugal force and rotary movement. The rotary mixing chamber is operated electronically via the control panel and can be set to create either a symmetrical or an asymmetrical spreading pattern. The optimised scoop geometry and dimensions ensure a high level of precision over the selected spreading widths of 2-10 m, 3-12 m or 4-14 m

Kick-back protection on the spreading disc

On contact, the entire distribution system folds away to the back, preventing damage to the spreader.

The Stratos drive systems are designed for maximum efficiency at minimum costs.

Vehicle hydraulic system – The municipal solution

In this variant, the spreader is simply powered by the existing hydraulic system of the carrier vehicle. The regulation of the power requirement in LS hydraulic systems means that, due to the low power required during spreading operations, the carrier vehicle needs to share less performance, with lower fuel and oil consumption.

Wheel drive – The conventional solution

The drive power comes from a separate wheel running at the rear of the truck. The wheel’s position has been optimised to enable easy and trouble-free connection to the driveshaft for discharge.

Innovative, CO₂-neutral Rotopower – The patented solution

In this system, the required drive power is taken directly off the rear wheel hub and used to further power the vehicle, thus creating a fuel-saving solution with optimum performance.

Engine drive – The vehicle-independent solution

The diesel engine is integrated at the front of the spreader, which reduces the required body length. The start/stop function can now be actuated both via the control panel in the cab and directly on the engine. The performance of the engine drive has also been designed to have minimum power requirements, resulting in low fuel consumption.

The Schmidt EvolutionLine comprises three operating concepts and provides professional solutions to make de-icing easier and more efficient. Their modular structure offers a completely flexible configuration, making it possible to precisely adapt the control panels to the required needs.

ES control panel – The premium solution

The ES control panel of the Schmidt EvolutionLine is the smartphone among the control panels that meets all current and future operational requirements. The frost-proof 7” colour touchscreen display is sited in a splash-proof, sturdy housing and ensures comfortable handling, plus a long service life. The spreading density, spreading pattern and spreading width are adjusted via ergonomic click-turn control knobs, while eight illuminated push buttons operate the primary and menu-dependent functions. Equipped with optional additional components, the ES control panel can be easily upgraded to become the high-tech control centre of the spreader.
