A snow and ice control spreader and sprayer comprises a granular material hopper, a granular material delivery system, at least first and second liquid tanks mounted on both sides of the hopper, the first tank having a first volume and the second tank having a second volume, the first volume being greater than the second volume, a liquid delivery system, and a manifold.

According to the present disclosure, road surface state information (road surface frictional force) is acquired and monitored together with road surface temperature information, road surface moisture information, and road surface salt concentration information of each road to determine whether to spray a deicing agent and whether to re-spray a deicing agent as a subsequent process depending on whether to satisfy not only a road surface temperature condition, a road surface moisture condition, a road surface salt concentration condition, but also the road surface state condition of road freezing.

A powered hand-held spreader device is disclosed that has a handle that allows a user to grip and hold the device with one hand. The spreader includes an adjustable shutter, controlled by a rotary dial, to allow for distribution of a range of different granular products that require different flow rates for distribution. The granular product is contained in a hopper. The product can be distributed over various types of terrain, including, but not limited to, lawns, gardens, and paths. The spreader is driven by an electric motor actuated by a trigger. A spinning rotor plate distributes the granular product fed from the hopper. A trigger lock is optionally available to lock the trigger in the on position during use and to prevent actuation when the trigger is in the off position. An adjustable side deflector optionally can be used to control the distribution pattern of the granular product.

Method for controlling a device for changing the spreading ring sector of a disc spreader including a controllable metering device, a distributor disc arranged underneath the metering device and provided with thrower blades, and the device for changing the spreading ring sector of the granular material on the ground. Functional dependencies of a setting parameter of the device for changing the spreading ring sector on a throwing parameter are stored in a database of a control unit assigned to the device for adjusting the spreading ring sector, and a set point value of the throwing parameter or of the setting parameter corresponding thereto is input in the control unit. An actual value of the throwing parameter is determined using a sensor, arranged near to the circumference of the distributor disc, and the actual value of the throwing parameter is compared with the set point value thereof in the control unit.

The present invention relates to: an apparatus and system for detecting a road surface condition, wherein the road surface condition is determined through a sound signal; and a method for detecting a road surface condition by using same. The apparatus for detecting a road surface condition according to the present invention comprises: a sensor unit which is installed on a road and measures a sound signal generated according to a moving of a moving object on the road; and a control unit which distinguishes the sound signal measured by the sensor unit into normality or abnormality and determines, in case of the abnormality, the road surface condition including at least one of rainfall (wet), frozenness (icy), slush, and snow cover (snowy) so that a quick and accurate action corresponding to the road surface condition of a specific section can be made from a distanced place.

An autonomous vehicle is provided. The autonomous vehicle includes one or more sensors and an autonomy computing system. The autonomy computing system includes at least one processor in communication with at least one memory device. The at least one processor is programmed to receive sensor data from the one or more sensors, and receive weather-related data from a mission control computing system. The weather-related data include fleet data from autonomous vehicles in a fleet. The fleet includes the autonomous vehicle. The at least one processor is further programmed to determine an icy condition is present based on the sensor data and the fleet data, and determine de-icing strategies based on the icy condition.

An implement for attachment with a vehicle. The implement includes at least one rail system that operably engages with the vehicle and has a first end, a second end opposite to the first end, and a longitudinal direction defined therebetween. The implement also includes a drop spreader that moveably engages with the at least one rail system along the longitudinal direction between a filling position and an operating position, wherein the longitudinal direction of the at least one rail system is nonparallel with a longitudinal direction of the vehicle.

Skid-steer type power unit engageable with an implement using an attachment assembly including an attachment frame and a hitch. An arcuate frame member is located forwardly of the attachment frame and is engaged therewith in such a way that the frame member pivots about a vertical axis located forwardly of the frame member and generally centrally positioned relative to the attachment frame. The frame member pivots in response to actuation of a hydraulic cylinder. The power unit includes a system for transferring weight of the implement rearwardly onto the power unit. A belt-drive power-take off system on the power unit powers the implement's operation. An underbelly drop spreader is located between the front and rear wheels of the power unit and a brine delivery system distributes brine from nozzles located rearwardly of the rear wheels. A unique control panel permits operation of all systems on the power unit and implement.

A mobile snow processing and de-icing machine and method is disclosed. The device comprises a collecting unit featuring cylindrical and circular brushes to effectively scrape and remove snow from surfaces. Turbo-suction sweepers, driven by Turbo-suction motors adapted to clear the scraped off snow through a collecting tube. A de-icing unit employs a heated metal grid at an inlet of a de-icing tank, converting collected snow into slush. Connected to the collecting tube's output, the de-icing tank further mixes the slush with a prestored de-icing solution, preparing a diluted deicing solution. The device further provides a sprinkler unit linked to an outlet of the de-icing tank, allowing a controlled spraying of the diluted de-icing solution back onto surfaces. This comprehensive mobile solution ensures efficient snow removal and proactive prevention of snow formation.

A method for controlling an industrial vehicle comprising the steps of: detecting a physical feature that determines a local narrowing or a widening of said road route; calculating treatment parameters of the road surface adapted to be used in the presence of said physical feature; calculating an estimated time for reaching said physical feature; calculating a time interval value required for a complete implementation of the second treatment parameters; and starting the implementation of the second treatment parameters at a time that is equal to the estimated time excluding the time interval of complete implementation.
