ARVEL has a wide range of salt spreaders that can be installed on all types of carriers, from lightweight 3.5 ton vehicles to 32 ton heavy trucks and covering various tool carriers and agricultural tractors. It is the carrier vehicle that defines the compatible range of salt spreaders and therefore the onboard material carrying capacity (of salt, sand, gravel, pozzolan, etc.) ranging from 0.6 m3 to 14 m3.
Using a salt spreader for treating road surfaces calls for a remote control box mounted in the vehicle cab for controlling the salt spreader’s various settings (starting, spreading density, width, asymmetry, brine, etc.) as well as the controls for the light systems.
We build all of our own electronic control systems.
Given the highly aggressive environment that this machinery is subjected to, ARVEL salt spreaders are made from AISI 304L stainless steel or mild steel with protective layers and a baked-on power based paint coat to maximize the salt spreader’s service life.
The salt spreader’s extraction system move the material to be spread (salt, sand, gravel, pozzolan, etc.) from the hopper to the spreader unit that coats the road surface.
There are three different extraction systems:
A chain with very wide stainless steel or specially treated steel bars
Inspired by the manure spreader systems used in agriculture and/or road surface finishers in construction use, this is currently the best performing and safest system for guaranteeing 100% efficiency to the operator with all kinds of materials, even the most corrosive ones.
Working like a moving base system across the whole of the feed hopper base width, this system thanks to its wide extraction width, avoids the “dome” and/or “tunnel” effects caused by low temperature wet materials. Thanks to its wide surface area in contact with the salt, this system requires only a slow rotation speed to operate effectively.
It can spread all kinds of melting materials like salt, but also materials with larger grain sizes (sand, gravel and pozzolan) stored outdoors without any protection.
The chain is driven by gear teeth. They are mounted on a shaft that is directly coupled to a hydraulic motor for regulating spreading. The gear drive avoids any sideways chain motion and slipping.
Reinforced chevron rubber belt
With the rubber belt material extraction system it becomes possible to work with materials that are not uniform while retaining excellent spreading precision.
The belt comprises a rubber strip with reinforced double chevrons and it is guided by two toothed rollers. The rollers are designed to reduce any belt slippage to a minimum. Its alignment and tension still call for daily attention.
Helical reinforced variable pitch feeder screw
This extraction system comprises a helical variable pitch feeder screw located at the base of the hopper. It is covered by a protective cone to protect it during hopper loading.
This system only works properly with fine, good quality salt that is stored under cover.
The spreader unit (also known as the “funnel”) is made from AISI 304L stainless steel with a roto-molded polyethylene chute that ensures very good low temperature slide characteristics.
The materials fall vertically so that they do not stick to the sidewalls.
An asymmetrical mechanical or electrical system allows spreading in five different setting positions covering widths of 2 to 14 meters.
The disk height is adjustable to comply with a working height of 400 mm (European Standard PrEn15597/1). The spreader unit has three adjustable positions: Spreading, washing and transportation.
To see the salt during spreading, a LED spotlight is positioned close to the disk.
All of the drive solutions are available for operating the salt spreader:
The salt spreader can operate with the carrier vehicle’s specialist winter operations hydraulic circuit, as the equipment is compliant with European standard EN15431.
A diesel engine is placed directly on the salt spreader with an electric starter motor, it is controlled from the control unit located in the cab.
A gasoline engine is placed directly on the salt spreader with an electric starter motor, it is controlled from the control unit located in the cab.
Using a salt spreader when treating road surfaces requires a control box that is remotely located in the vehicle cab. It allows the driver to control the various salt spreader operating parameters (starting, gram weight, spread width, brine, etc.) as well as controlling warning lights.
We make all of these electronic control boxes ourselves.
For these boxes, the electric power circuit is protected in a sealed box and the electrical outputs are protected by electronic technology for detecting faults and protecting components.
Note: Should the control box fail, the salt spreader equipped with a system so that it can operate in manual mode.
The boxes listed below are interchangeable.
Ecos EUROPE control box
Equipped with backlit control buttons, the Ecos EUROPE control box uses a CAN-BUS layout for regulating the following spreading parameters:
Ecosat10 control box
This is the most complete control box.
The Ecosat10 control box is equipped with a microprocessor with a wide range of possibilities for programming and viewing the various spreading parameters (spreading width, asymmetry, dosage) on a backlit (150×90) LCD
The control box comprises the following elements:
It communicates with the external power unit via a CAN-BUS connection (a Bluetooth link is optional).
These control boxes control the spreading of six different materials using nine spreading programs for each material. You can save different types of settings for spreading, asymmetry, grain size, types of materials, etc.
All ARVEL salt spreaders are suitable for use with a wide range of storage support systems. They are designed to reduce the time required to fit and remove the bodywork and are suited to all requirements and all vehicles.
Wheel operated support stands
A support system using four telescopic manual wheel operated stands. The front stands are designed to pass over the side panels.
These support stands require operator intervention to fit and remove them as they remain on-site.
Automatic support stands
An automatic support system for tipper bodies with front supporting rollers, front stands that retract into the salt spreader’s chassis and retractable rear supports.
They remain on the salt spreader full time and do not therefore require removal and storage.
Removal cradle for Ampliroll arms
The salt spreader is mounted on a cradle equipped with a front hook and two offset rear rollers. To protect the carrier vehicle’s mechanical systems, a polyethylene base is fitted between the two.
A galvanized steel or polyurethane screen with a PVC cover over a metal structure.
Depending on the use and your requirements, the salt spreader can be equipped with various warning lights as listed below:
An AISI 304L stainless steel protection cone is located over the extraction system. It is height adjustable depending on the kind of material to be spread.
A three-function stainless steel blade crusher (for crushing clumps, mixing, regulating/setting dosage levels) positioned transversely in the salt spreader hopper. It is used to regulate, dose, crush and mix the materials to ensure continually consistent spreading. It turns in the opposite direction to the carrier.
The wetting system is used to spread a mixed solution of salt and brine “liquid salt”.
Using our own design, the brine pump is manufactured with a nitrile rotor and an AISI 316 stainless steel body to ensure reduced maintenance.
The brine tanks mounted on either side of the hopper (to better spread the load) are made from recyclable polyethylene (PEHD).
The solid/liquid solution mix can be set to 0 to 30% from the control box.
To make it easier to load the hopper from large capacity loaders and to avoid waste, raised sides can be fitted to the salt spreaders.
