Schmidt ｜Spreader｜eStratos 4.0 - 12.0 m³
Sustainable electric drive
The eStratos is equipped with a front-mounted battery pack (6.2 / 12.4 / 18.6 kWh, 48 V) and an electric motor. The powerful batteries enable two spreading operations with two full hoppers each without recharging. Thanks to the integrated charger, the eStratos can be charged at any 230 V AC connection. The lithium-ion battery technology with integrated heating system is specially designed for use in temperatures down to -20°C. Thanks to the use of hydraulic technology, the eStratos achieves the same performance as conventional hydraulic machines. It retains its full performance and is not affected by the limited power of the carrier vehicle. When used on an electric carrier vehicle, the range of the carrier vehicle remains unchanged. Compared to a motorised spreader, the eStratos is significantly quieter. In addition, the safe 48 V DC system can be maintained without special training or safety measures.
Mounting and demounting systems
Maximum safety – Mounting and demount systems
The key components and sturdy construction of the 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.
Dosage and conveyor systems
Conveyor belt system
The 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 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.
Pre-wet equipment
The 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.
Distribution systems
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.
Premiumplus distribution system
The Premiumplus 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.
Control and information systems
The Schmidt EvolutionLine comprises 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.
