1, China\\ s electric forklift market prospect is broad
The modern logistics industry has become a pillar industry of national economy of the new century. It no t only

form the modern supply chain carrier and the basis of the value chain management, tractor forklift attachment
production, circulation and

consumption of org anic connection, speed up the process of social reproduction, and the fastest speed, best

practice and optimal combination of complete goods from production to consumption areas of the transfer

process to maximize the savings in distribution costs. Forklift known as \"the handling of God\" plays a huge

role in the logistics field. In recent years, electric forklift will be more and more customers. But from the

point of view of electric forklift market share of only 21%, compared the ratio of the proportion of European

and American markets electric forklift, there are still considerable differences. This shows that our electric

forklift has broad market prospects.
2, electric forklift has a significant energy-saving environmental advantages
In addition to low noise and exhaust emission characteristics, the many advantages of electric forklifts, in

fact, the use of electric forklifts and maintenance cost relative internal combustion forklifts have a great

advantage.
The use of cost: the cost of consumption of electrical energy consumption costs than diesel or liquefied

petroleum gas. If our forklift trucks with a payload capacity of three tons to do, each shift of a diesel

internal combustion forklift truck diesel consumed (according to each frequency of consumption of 40 liters of

diesel fuel, the vehicle 60 per hour VDI cycle consumption of 5.5 liters of diesel to calculate a) costs about

196 yuan (4.9 yuan per liter of diesel). A three tons electric forklift is 80 volts 500AH battery (the battery

storage of electricity for 8 × 500 = 40 kWh), an operating frequency (80% discharge, in accordance with the

120% supplementary charge ratio, need to consume electricity is about 40 degrees) costs about 140 yuan (3.5

yuan per unit in accordance with the current industrial electricity prices). Can save 56 yuan per day,

calculated in accordance with 250 days a year, you can save $ 14,000 a year in energy costs. If you use five

years to calculate, you can save $ 70,000.
Electric forklift due to its operational control is simple, flexible, operating strength of its operation is

relatively internal combustion forklift trucks in terms of light a lot of its electric power steering system,

the acceleration control system, hydraulic control system and brake system is controlled by electrical

signals, greatly reducing operator\\ s labor intensity, so that a very big help for improving its efficiency and

accuracy of the work.
Maintenance costs: maintenance cycle in terms of length of two to three times of electric forklift maintenance

cycle internal combustion forklifts,fork lift truck attachments
usually internal combustion forklift maintenance cycle up to 500 hours of

work, and electric forklifts have been able to reach more than 1000 hours maintenance cycle. Mai ntenance

content, electric forklift maintenance than internal combustion forklifts, maintenance simple, usually as long

as the parts of the lubrication of some joint activities such as the bearing of the door frame, turn to other

bridges to check the clean up to every 2000 or 3000 hours to be replaced once the hydraulic oil, gear oil and

hydraulic filters, other materials are very limited. Other than internal combustion forklift truck lubrication

for up to 500 hours (usually about every 300 hours) is necessary to replace the engine oil and oil filter

every 1000 hours to replace the hydraulic oil, engine oil, transmission oil and oil filter device. Also

replace the belt (engine timing belts, generator belts, etc.). Or three tons forklift example, according to

the calculation of operating 2000 hours per year, the maintenan ce costs of the internal combustion forklifts

3,000 to $ 4,000 (just the cost of materials), while the electric forklift maintenance costs $ 1,000 to $

1,500 (cost of materials) .
Maintain the time required by the maintenance of internal combustion forklifts electric forklift maintenance

interval cycle is relatively long, at the same time, the time required of each maintenance than internal

combustion forklifts, so significant savings in labor costs, maintenance needs, in fact, more of this

substantial forklift downtime is greatly reduced, so that the economic benefits of improved forklift

efficiency is difficult to calculate.
Electric forklift battery service life of 1,500 charge-discharge cycles, converted into the forklift working

hours of 10,000 hours, the same which is also equivalent to an internal combustion forklift engine overhaul

time, so when the electric fork lift battery replacement cost and engine overhaul costs are relatively close,

but replace the battery faster than the speed of the engine overhaul (or replacement of the engine speed) is

much faster, but also reflect on the advantages of time efficiency.
Thus, while we make in the purchase of electric forklift spend more expensive than the same load capacity of

internal combustion forklifts to be 30% higher, but the total cost of using directly measured data can be

seen, in fact, the total cost of electric forklift than the internal combustion forklift trucks is much lower.

The one hand, more and more the forklift indoor operation, such as vehicle exhaust emissions requirements

getting higher and higher. Europe and the United States and other places have strict rules, the indoor ban on

the use of internal combustion forklifts. Even now in the country\\ s domestic laws and regulations hav e not yet

started to strictly limit the internal combustion forklifts are used indoors, but compared to internal

combustion forklifts, electric vehicles, low-noise, no exhaust emissions advantages have been recognized by

many users. In addition, selection of electric forklift trucks, there are some technical reasons. The rapid

development of electronic control technology makes electric forklift operations to become more and more

comfortable, the broader the scope of application, more and more solutions to the logistics, such as electric

pallet trucks, electric stackers, forklifts, three narrow channel forklift such as internal combustion

forklifts, electric forklifts to solve these problems, in particular, played a very important role in

warehousing and logistics solutions. These in terms of demand for electri c forklift market growth rate will be

faster and faster, electric forklift market share will be growing.
3, electric forklifts become more perfect towards the practical
Electric forklift vehicle power supply, power, motor-driven wheel driving, in line with road traffic, the

requirements of safety regulations. The advantages of electric forklifts is: it does not pollute the

atmosphere emissions of harmful gases, even if the power consumption are translated into emissions from power

plants, except sulfur and particulates and other pollutants were also significantly reduced due to power

plants are mostly built away from populated dense city, less damage to humans and the plant is fixed, the

concentration of emissions, to get rid of various harmful emissions easier, also has the relevant technology.

Electricity from a variety of primary energy to obtain, such as coal, nuclear, hydro, th e lifting of the

depletion of oil resources has become increasingly worried about. Charging electric forklifts can take

advantage of evening electricity trough when surplus electricity, day and night can be fully utilized, and

greatly improve its economic efficiency power generation equipment. Some studies have shown that After

smelting, the same crude oil sent to the power plant into the battery, rechargeable, battery-powered forklift,

its energy efficiency The refined into gasoline, and then the gasoline engine-driven forklift, so conducive to

saving energy and reduce carbon dioxide emissions, it is these advantages, research and application of

electric forklift become a hot topic in the forklift industry.
The difficulties of electric forklifts is too little energy stored in the battery unit weight, and also more

expensive due to the electric forklift battery, not any form economies of scale, so the purchase price is more

expensive.
The battery is the primary key in the development of electric forklift, electric forklifts, to rely on

advanced batteries after 10 years of screening in order to application in a wide range, generally optimistic,

nickel hydrogen batteries, lithium ion and lithium polymer batteries. Ni-MH battery unit weight of stored

energy than lead-acid batteries twice as many of the other properties are better than lead-acid batteries. But

the current price of lead-acid batteries of four to five times, making great efforts to research it down.

Lithium is the lightest chemical properties of a very reactive metal, lithium-ion battery per unit weight of

energy storage for three times that of lead-acid batteries, lithium polymer batteries to four times, and

lithium resources are abundant, the price is not expensive, is very hope the battery. Of the development of

nickel-metal hydride batteries and lithium-ion battery industry has achieved rapid development. Electric

forklift technology, have a huge progress in recent years, such as: AC induction motor control, rare earth

permanent magnet brushless motor control, battery and vehicle energy management systems, intelligent and fast

-charging technology, low-resistance tires , lightweight and low-drag body, brake energy recovery, etc., these

advances in technology to make electric forklift to become more perfect and towards the practical.
