EHS become the dominant factor in the development of the world's forklift

Page 1 of 2 Introduction

modern industry, material handling and storage equipment is to reduce the supply chain costs indispensable important tool.
1 forklift selected ehs Advantages and Disadvantages:

Currently, the most common form of truck by force is divided into: internal combustion forklift truck and battery, the total market which accounts for about internal combustion forklift 85% of forklift batteries account for about 10% to 15%. With the promotion of energy saving and emission reduction, increasing year by year the amount of battery forklift. Such as the 2007 outbreak in Taihu Lake in Wuxi cyanobacteria events, forklift sales of the battery is very obvious.

1.1ehs impact on the internal combustion forklifts: internal combustion engine-powered forklift to power strong climbing ability, using a wide range, the disadvantage is the exhaust and noise pollution of the environment, harmful to human health. The future will be wider use of electronic combustion forklift injection and common rail technology. Exhaust gas catalysis, purification technology will reduce emissions of harmful gases and particulates. lpg, cng fuels such as hybrid electric forklift trucks and will develop rapidly. Select the dynamic form depends on the forklift working condition and cost factors. Early production of the internal combustion engine powered forklifts, the majority of gasoline used was within the 212 to the north of the main models. However, due to technological level, performance and maintenance habits,[link widoczny dla zalogowanych], and many other factors, apart from a few imported nissan gasoline engine, the current domestic gasoline forklift has been basically no longer in production. The diesel fuel because of its cheap power, climbing ability, low demand on the road, long duration operation, maintenance, performance, accessories, cheap, etc., but the vibration of the larger, noisier, with smoke emissions, the formation of air pollution and other shortcomings, but also to development is limited. LPG forklift trucks as early as 60 years in the last century began to use in foreign countries. In recent years, with the increasing demand for domestic environmental protection, domestic internal combustion forklift trucks started using LPG as fuel. Data shows that lower fuel prices of LPG forklift, operating a longer time, stable, low noise, after the addition of catalyst, carbon monoxide and hydrocarbon emissions can lower limit down, so almost LPG forklift No smoke, no air pollution, both for outdoor work, also suitable for indoor operation. However, as gas storage, transport, usage and other aspects that a lot of inconvenience, LPG forklift slow development in the country.

1.2ehs impact on battery forklift: Forklift batteries to the battery - the motor-driven, starting performance, high energy conversion efficiency, smooth operation, no noise, no emissions, no air pollution, simple operation; disadvantage is maintenance of the electronic control system is more complex, need to be charged room and charging equipment, spare batteries need to shift operations on the road for high, due to limited battery capacity, motor power generally small, poor climbing ability, therefore, battery forklift for indoor flat, solid ground operations, especially for air cleanliness requirements for high storage operations. In addition, the driving power of the battery forklift limited by battery capacity, in general, it is not suitable for large tonnage from the weight of the largest domestic battery forklift from the weight of 5 tons. 2007, non-ferrous metal prices, causing the battery price increases, have an impact on the battery forklift. In addition, the number of domestic battery charge and discharge is generally less than 800, about 2 to 3 years to be replaced, so the high cost of battery forklift purchase.

continuous improvement at home and abroad are in the lead-acid battery technology, by improving the purity of their materials in the complex number of charge cycles, capacity and power efficiency has been greatly improved. As technology advances, electric forklift operation has exceeded the limitations of small tonnage. Current international electric forklift truck of the total production accounted for 40% (10% domestic to 15%), in Germany, Italy and some other Western European countries the proportion of electric forklifts up to 65%. In recent years, with the AC induction motor variable frequency technology, and high-power semiconductor devices and greatly improved the speed of microprocessors, AC induction motor drive system and DC motor drive systems, high efficiency, small size, small simple structure, maintenance-free, easy-to-cooling and long lifetime. The system wide speed range, and to achieve constant torque low-speed, high-speed constant power operation, good to meet the requirements of electric vehicles, the actual driving speed characteristics.

can be said that rapid advances in semiconductor technology is the birth of the AC motor technology revolution, the AC motor control greatly increased; and with the falling prices of electronic components, AC motor controller to reduce the cost of to make extensive use of AC drive system. AC drive system for trucks, the overall performance significantly improved, machine failure and replacement rate was significantly lower electrical components, reliability enhancement; forklift higher productivity per unit of time, operation and maintenance costs, will give users a very significant benefits. Therefore, the AC drive system, once launched, not only by the forklift manufacturer the trust, but also more and more users of all ages, as in recent years, electric forklift technology development trends and direction. Its advantages in the following points: ① AC motor maintenance-free life. ② using regenerative braking to reduce mechanical wear. ③ easy to program, control has increased greatly. ④ forklift operation more comfortable.

Luxurious lingerie is only a sexy chemise away
Today's chemises are soft and luxurious, whether worn as undergarments, nightwear or even outerwear. Like many of today's hot lingerie items, however, chemises have a long and much more practical history. Provided here is a brief history of chemises through the ages.
Ancient Cultures
In Ancient Greece and Rome, tunic-style garments were worn by both men and women. These simple gowns are believed to be the prototypes of modern chemises. However, the garments were worn alone, therefore functioning as outerwear.
Middle Ages
The medieval period marked the true beginning of chemises' use as undergarments. At that time, chemises were unisex garments. Women wore them long, underneath skirts and bodices or full-length gowns. Men wore them as somewhat shorter undershirts [link widoczny dla zalogowanych], paired with braies (a form of leggings) and covered by doublets, robes or other garments.
At that time and for many centuries to follow, chemises served an extremely practical purpose. The chemise was one of the earliest incarnations of underwear. It protected expensive outer garments from sweat and bodily oils. In those days [link widoczny dla zalogowanych], the chemise was the only piece of clothing that was regularly washed.
Evolution of the Chemise
Chemises remained an important and practical undergarment until the early 20th century. As fashions changed, so did the chemise. Women's styles evolved into the camisole (once used to cover the corset) and full slip. Men's chemises gradually became shorter and more fitted, eventually becoming the undershirt of today.
Homemade Chemises
Chemises were traditionally made at home. A home seamstress could create each chemise from a single piece of cloth, which lessened waste dramatically. Working class people of both genders wore simple, rough chemises that were generally made of linen or other common fabrics. Wealthier people enjoyed supple chemises made from silk or other luxurious fabrics.
Chemises Today
Today's chemises are luxury items, crafted of rich materials such as silk and designed to enhance sex appeal. Some chemises retain practical value, offering a sleek, clean line under thinner dresses and blouses. Others are designed strictly as nightwear or naughty lingerie, offering such daring options as lace and fishnet.
Today, there is little difference between chemises and camisoles, and many people use the two terms interchangeably. Chemises may also resemble negligees, particularly the babydoll style. Chemises historically provided sleeves, although many of today's more risqu茅 styles are sleeveless.
Fitting chemises is extremely easy, making them popular gift items. A chemise is designed for a loose and flowing fit, as opposed to the precise measurements that are required for pieces such as corsets. Chemises are generally sized according to dress size [link widoczny dla zalogowanych], although some are marketed as "one size fits all."
Chemises have undergone many changes since their debut in Ancient Rome [link widoczny dla zalogowanych], but the basic structure of the garment remains the same. A comfortable, thin piece that can be worn as naughty lingerie, underwear or sleepwear, the chemise of today is a luxurious and multifunctional addition to any woman's wardrobe.
