WIKIPEDIA - ELECTRIC VEHICLES

An electric vehicle, or EV, is a vehicle with one or more electric motors for propulsion. This is also referred to as an electric drive vehicle. The motion may be provided either by wheels or propellers driven by rotary motors, or in the case of tracked vehicles, by linear motors.Unlike an internal combustion engine (ICE) that is tuned to specifically operate with a particular fuel such as gasoline or diesel, an electric drive vehicle needs electricity, which comes from sources such as batteries or agenerator. This flexibility allows the drive train of the vehicle to remain the same, while the fuel source can be changed.The energy used to propel the vehicle may be obtained from several sources, some of them more ecological than others:on-board rechargeable electricity storage system (RESS), called Full Electric Vehicles (FEV). Power storage methods include:chemical energy stored on the vehicle in on-board batteries: Battery electric vehicle (BEV)static energy stored on the vehicle in on-board electric double-layer capacitorskinetic energy storage: flywheelsdirect connection to land-based generation plants, as is common in electric trains and trolley buses (See also : overhead lines, third rail and conduit current collection)renewable sources such as solar power: solar vehiclegenerated on-board using a diesel engine: diesel-electric locomotivegenerated on-board using a fuel cell: fuel cell vehiclegenerated on-board using nuclear energy: nuclear submarines and aircraft carriersIt is also possible to have hybrid electric vehicles that derives energy from multiple sources. Such as:on-board rechargeable electricity storage system (RESS) and a direct continuous connection to land-based generation plants for purposes of on-highway recharging with unrestricted highway rangeon-board rechargeable electricity storage system and a fueled propulsion power source (internal combustion engine): plug-in hybridElectric vehicles can include electric airplanes, electric boats, and electric motorcycles and scooters.

ELECTRIC MINI DUMPER

Dumper Jet – Even if at first sight the Made in Italy design makes us think of the beauty more then the strength of this machine, then you will need to try It to change your mind. Are you in need to transport up to 0,4 tons? Well with the DUMPER JET becomes a piece of cake. The strong frame, the right balance between the load and the wheels, coming from a careful study, gives the user confidence, increasing the handiness in the manoeuvre operation even on gradients up to 30%. The semi automatic tilting of the skip is helped by an electronic system that controls the forwarding or the backing up at 2 different speed, slow or fast, making the discharge secure and practical in closed environments respecting the anti pollution normative for the noise and exhaust fumes emission.

ELECTRIC INDUSTRIAL TRUCKS

Defintion: Electric Industrial Trucks are used to move materials over variable paths, with no restrictions on the area covered by the movement. 

The major types of industrial trucks are:

1) Hand Trucks
2) Pallet Jacks
3) Walkie Stacker
4) Pallet Trucks
5) Platform Trucks
6) Counter-balanced lift trucks
7) Narrow Aisle Straddle trucks
8) Narrow Aisle Reach Truck
9) Turret Truck
10) Order Picker
11) Side-loader
12) Tractor Trailer
13) Personnel & Burden Carrier
14) Automatic Guided Vehicle (includes Tow AGV, Unit Load AGV, Assembly AGV, Light load AGV, & Fork AGV)


What? A forklift truck (a.k.a forklift and sideloader) is a powered industrial truck used to lift and transport materials, normally by means of inserting steel forks under the loads. Can be electrically powered or run on fuel.Areas of Application - Most commonly used to move loads stored on pallets. Forklift trucks are available in many variations and load capacities. In a typical warehouse setting most forklifts used have load capacities of around one to five tons, though machines of over 50 tonnes capacity have been built and operated. Able to operate effectively 24/7 with no loss of power & life-time running costs can be lower than electric trucks, they can be used even in the most sensitive environments. Companies will not face battery disposal problems & there will be no harmful fumes under normal operating conditions. 

Pallet Jack

What? A tool used to lift and move pallets; the front wheels are mounted inside the end of the forks, and as the hydraulic jack is raised, the forks are separated vertically from the front wheels, forcing the load upward until it clears the floor. The pallet is only lifted enough to clear the floor for subsequent travel.
Areas of Application - Powered pallet jacks are motorized to allow lifting and moving of heavier and stacked pallets. These generally contain a platform for the user to stand while hauling pallets around a warehouse or loading/unloading trucks. The powered pallet jack is generally moved by a throttle on the handle to move forward or in reverse and steered by swinging the handle in the intended direction.

Electronic Platform Trucks

What? Electric platform trucks are electric powered trucks with a large flat surface for holding objects to be transported. Some are also called warehouse utility vehicles, electric trolley carts, or powered platform truck vehicles.hat is aklift Truck?What? A forklift truck (a.k.a forklift and sideloader) is a powered industrial truck used to lift and transport materials, normally by means of inserting steel forks under the loads.

A LITTLE SPOT ON ELECTRIC TRANSAXLES



Transmission + Axle = Transaxle

The transaxles is one of the main important part of an electric vehicles. A transaxles is composed by an electric motor flanged on a reducer that contains also a differential. So, as you can understand a similar item need to be more strong and compact possible for weight and dimensional problems that can occurred on some chassis. Transaxles are used on a so big range of electric vehicles, from mobility scooters to agricultural platform truck, from amusement to quad bike, from hospital bed movers to airport stairs and so on. Each electric vehicles needs his electric Transaxles.
