Atex explosion proof vehicles |
Our explosion-proof vehicles are oriented to market segments dealing with potentially hazardous environments like chemical and petrochemical industries, production sites of mineral oil and natural gas, mining, tunnel construction and maintenance and many other sectors. Electric vehicles used in these areas must be designed to prevent any normal operation of the equipment from igniting the atmosphere. Alkè electric vehicles with explosion-proof conversion are designed according to ATEX 94/9/EC for category 2G (Zone 1) and 3G (Zone 2), Gas group IIA/IIB, Temperature class T3/T4 and for category M2 T450°C for underground activity inside not coal mines tunnels.
The flameproof conversion regards the general electric circuit, battery and battery connectors and all parts which might cause high temperatures or sparks for various reasons. All original electric components are treated in compliance with requirements for Category 2G, 3G and M2, specifically guaranteeing that none of them will be able to cause an ignition or explosion in the surrounding environment. These interventions specifically refer to:
The surface temperature is checked by specific temperature sensors, according to the Temperature Class / Temperature limit requested, to avoid the risk of overheating. If this occurs the vehicle will automatically shutdown, lighting the indicator. An earth leakage check system (only on 2G/M2 versions) automatically shuts the truck down in case the max value should be exceeded, lighting the indicator on the dashboard panel.  An appropriate “Reset” pushbutton allows the truck to be moved out of the dangerous area in case of temperature and (only on 2G/M2 versions) earth leakage sensor’s alarms intervention. The electric wiring is done by using both armoured and non armoured cables, blue cables for connection of components protected with intrinsic safety mode and with certified cable glands for proper 2G/3G/M2 category. Bipolar battery cut-off switch is provided. On 2G/M2 flameproof utility vehicles the battery is Ex-e type with battery filling system. Battery connectors are Ex-d type certified. On 3G versions battery and battery connectors comply with the standard EN 60079-15.
 The disc or brake drums are provided with wear and temperature sensors to guarantee any possible wearing out of the braking material which might cause sparks due to the metal rubbing together and that a high friction temperature might exceed the value of the Temperature Class / Limit.
On 2G/M2 explosion-proof vehicles seats are covered with antistatic material and external surface of plastic components, when necessary, is treated with electro conducting coating.
All tyres are electro-conductive. Accessories, such as flashing beacon, reversing beeper, headlights are explosion-proof suitable for category 2G/3G/M2.
 Electric vehicles with ATEX certification: electric vehicles for use in potentially explosive areas, that require ATEX approval, for oil wells and gas extraction, tunnels, chemical plants.
Alkè models available with ATEX 2G/3G/M2 explosion-proof conversion are ATX200E and ATX280E, main differences between them are:
These units have chassis treated with Cataphoresis anticorrosion process and it is built using tubular steel sections dimensioned to support heavy duty operations.
The front bodywork of the vehicle, the control panel and coverings and the back of the cab are built in reinforced fibreglass and finished with car paint (fibreglass is flexible, resistant to blows and can be easily repaired in the case of accidents).
Atex electric vehicles
Atex vehicles for use in potentially explosive areas.
They have separate excitation motors with maximum torque at zero revs and smooth distribution, which prevents skidding and loss of grip also on high risk land-types (sand, snow or ice) and guarantee start-up in ascent without hesitation. Thanks to their special motors and the particular control electronics, they raise the power, if necessary, by 6kW (8HP) nominal to a peak of 17.5 - 20kW (24 - 27HP) to allow operations even in the presence of uneven land and slopes.
The range on standard routes can reach up to 100 Km and covers without problems an entire working day even where frequent stops are required for load and unload operations.
The electric ATXs have an energy recovery motor brake system, which in the stopping phase prevents all waste of power and wear of the brakes.
 The special external battery chargers used by these vehicles guarantee a greater number of charges with respect to the technologies commonly used (greater number of charges = longer life of the battery set = saving of management costs).
It is not necessary to wait for the battery to be totally flat before re-charging it, the so-called “memory effect” present in other lower sectors is not found here.
The investment for an ATX E is re-paid in average terms by the maintenance costs, which are must lower if compared with equivalent diesel and petrol vehicles: maintenance is almost inexistent and there are noteworthy savings in fuel consumption. For an entire day’s work the cost for the complete charging of the battery sets is less than 2 euro.
It is important to know that the technical life, in working hours, of an electrical vehicle of this type is generally double, if not triple, with respect to a conventional fuel vehicle.
Powerful, robust and with ATEX certification: this ATEX electric vehicles have separate excitation motors (suitably adapted to follow ATEX regulations) with maximum torque at zero rpm and progressive supply of power and seamless to avoid skidding and loss of grip even on groung traditionally considered highly dangerous (sand, snow or ice)*. All electronics and components on the electric vehicles are fully endorsed for the strict ATEX electrics certification for ATEX directive.
