Choice of forklift

Forklift plays a very important role in the enterprise's logistics system, is the main force in the material handling equipment. Widely used in railway stations, ports, airports, factories, warehouses and other sectors of the national economy, is a highly efficient mechanized equipment handling, stacking and short-distance transport. Self-propelled truck appeared in 1917. During World War II, the truck developed. China from the early 1950s began manufacturing forklifts. Especially with the rapid development of China's economy, most enterprises have been away from the original material handling manual handling,
Lpg Gas Forklift Truck
 is replaced mainly mechanized handling. Thus, in the past few years, the demand for Chinese forklift market are double-digit annual growth rate.
Currently on the market to choose from truck brands, models of complex, coupled with strong technology and product itself is very professional, so the choice of models, vendor selection is a lot of optional enterprises often face. This paper introduces the model selection, brand selection, performance criteria and other aspects.
the model selection
Industry needs models and configurations.
1. Vehicle Classification
Forklift generally can be divided into three categories: internal combustion forklifts, electric Lpg Forklift Trucks and warehouse trucks.
(1) internal combustion forklifts
Internal combustion forklifts is divided into ordinary internal combustion forklifts, heavy trucks, container trucks and sides of the truck.
① ordinary internal combustion lpg forklifts

Generally use diesel, gasoline, liquefied petroleum gas or natural gas engines as power, load capacity of 1.2 to 8.0 tons, the operating channel width is generally 3.5 to 5.0 m, taking into account the emissions and noise problems, usually outdoors, workshop or other for exhaust emissions and noise do not require special place. Due to convenient refueling, it can achieve long-time continuous operation, but also capable of performing (such as rain) to work in harsh environments.
② Forklift Trucks
A diesel engine as power, load capacity from 10.0 to 52.0 tons, generally used for heavier cargo terminals, steel and other industries outdoor jobs.
③ Container Handler
A diesel engine as power, load capacity of 8.0 to 45.0 tons, is generally divided into the empty box stacker, heavy container forklift and reachstacker. Applied to container handling, such as container yard or port terminal operations.
④ Sideloader
A diesel engine as power, load capacity of 3.0 to 6.0 tons. Without turning, the fork has the ability to take the goods directly from the side, so the main fork to take a long bar used goods, such as wood, steel and so on.
(2) Electric Forklift
With motor-driven, battery energy. Carrying capacity of 1.0 to 4.8 tons, the operating channel width is generally 3.5 to 5.0 m. Since there is no pollution, low noise, it is widely used on the environment require a higher conditions, such as medicine, food and other industries. Since each cell is generally about eight hours at work needs to be charged, so for multi-shift working condition with battery backup.
(3) warehouse forklift
Warehouse forklift mainly for cargo handling and warehouse forklift design. Apart from a few warehouse forklift (such as hand pallet truck) is the use of human-driven, others are driven by an electric motor, because the body is compact, mobile and flexible, light weight and good environmental performance and have been widely used in the warehousing industry. When multi-shift operations, warehouse forklift motor-driven need battery backup.
① Electric Pallet Truck
Carrying capacity of 1.6 to 3.0 tons, the operating channel width is generally 2.3 to 2.8 m, fork lift height is generally about 210mm, mainly used for horizontal transport and cargo handling within the warehouse. Generally stand-walk-and two operating modes, you can choose according to efficiency requirements.
② electric pallet stacker forklifts
Carrying capacity of 1.0 to 1.6 tons, the operating channel width is generally 2.3 to 2.8 meters, the structure more than the door frame electric pallet trucks, fork lift height is generally within 4.8 meters, mainly for cargo warehouse stacking and loading and unloading.
③ reach truck
Carrying capacity of 1.0 to 2.5 tons, the whole door frame can move forward or retracted retracted operating channel width is generally 2.7 to 3.2 meters, lifting height up to about 11 meters, commonly used in the warehouse of medium height stacking, taking cargo operations.
④ electric order pickers
In certain conditions (such as supermarket distribution centers), does not require a whole pallet shipments, but in accordance with a variety of order picking up a variety of cargo pallets, this link is called picking. According to the height of the picking of goods, electric order pickers can be divided into low-pickers (within 2.5 meters) and the high order pickers (up to 10 m). Carrying capacity of 2.0 to 2.5 tons (low), 1.0 to 1.2 tons (in high, with cab upgrade).
⑤ low drive three stacking forklift
Usually equipped with a three-stacking head, forklifts do not need to turn, rotate the fork can be achieved and pick up the goods stacked on both sides of the channel width of 1.5 to 2.0 meters, lifting height up to 12 meters. Truck cab can not always upgrade in the ground, taking into account the limitations operative field, mainly for lifting height of less than six meters in working condition.
⑥ driving three high stacking forklift
Driving with low stacking three similar truck driving three high stacking forklift is also equipped with a width of 1.5 to 2.0 m three stacking head, channel, lifting height of up to 14.5 meters. Can enhance their cab, the driver can clearly observe any height of the cargo, the job can also be chosen. Three high stacking forklift driving efficiency and performance are superior to a variety of low-stacking forklift driver three, so the models have been gradually replacing the low three-stacking forklift driver.
⑦ electric tractor
Tractor using a motor-driven, with its towing capacity (3.0 to 25 tons), followed by pulling a few loading cargo car. Often used for transportation between the workshop or workshop large number of goods, such as automobile manufacturing warehouse to the assembly line of transportation, airport luggage transport.

How to choose the right forklift in the warehouse using?

Rated lifting the quality of each truck's center of gravity means that the goods in the truck within the standard load center distance, vertical mast gas powered forklift, starting from the time that can lift the quality of goods rose lift truck standards. Therefore, users in the choice of truck tonnage, according to the size of the center of gravity should be compared with the loading and unloading of the truck standard load centers, such as the center of gravity of the cargo is equal to or less than the standard load center distance forklifts, forklift rated lifting the selected quality is equal to or greater than about cargo to quality. If the center of gravity of the cargo truck is greater than standard load center
distance, you should buy the truck tonnage determined in accordance with the forklift truck loading a sample graph provided.
Second, the battery forklift choice
Battery forklift mainly used for indoor operations, generally used in batteries
counterbalanced forklifts , including three-wheel and four-pivot. For the narrow channel in the top shelf stacking and fork to take the goods into the floor elevator or need a job users can choose Reach battery Gas Forklift Trucks or pallet stacker battery.
Third, the truck type selection
Indoors (including warehouses, workshops, etc.) operations, in order to reduce air pollution and noise, generally used battery forklift appropriate; in outdoor work, especially in the field of road is not very flat, a good selection of internal combustion forklifts. Three kinds of internal combustion in diesel forklift truck use more common, if no special requirements, generally use diesel truck. Considering the small number of users northern winter temperature is low, the engine is not easy to start, etc., in order to facilitate the choice of gasoline truck engine start, but with the direct-injection diesel engines for use on lpg forklift
, solves the problem of difficulty in starting the engine in winter, so the gasoline truck sales of domestic truck market will be less and less. In addition, with state restrictions on the kind of pollution, increasing environmental requirements, selection of LPG forklift job as outdoor users is also increasing, and will become a trend.
Select four transmission modes
In internal combustion forklifts three kinds of transmission modes, the current domestic users to choose the most is the mechanical transmission and hydraulic transmission forklift truck, forklift due to the high price of hydrostatic transmission, use and maintenance requirements, troubleshooting problems, the reasons for higher maintenance costs, general users are do not use. Usually at work is not continuous, daily working time is not long (5h less), the mechanical drive trucks will be able to meet the requirements. For continuous work, work frequently, heavy load and two shifts, three shifts production industry, in
order to improve efficiency, reduce labor intensity of the truck driver, generally used in hydraulic transmission truck better. With hydraulic transmission to improve the reliability of the truck, because of its infinitely variable, the operation is very convenient and efficiency advantages, the choice of hydraulic forklift users will have increased.
Five, forklifts powered selection
The current number of major truck companies, in order to meet the different needs of customers, in each of the internal combustion forklifts are equipped with a variety of domestic and imported engines for users to choose, these engines not only do domestic and imported, as well as the size of the engine power are different. For the average user can choose domestic truck engine configuration, its price is cheaper, more convenient service.
For heavy workload, long working hours of the user, the choice of imported engines, in order to reduce the failure rate and increase its reliability. For particularly onerous working conditions, the working environment is particularly bad user, suggested the use of imported high-power engine.

Extend the service life of electric forklifts

Do electric forklift daily care can prolong the life of the truck. Reduce procurement costs and depreciation expense forklift. Many companies are aware of this truth, but in practical nursing electric forklifts, and do not know how to do it, here Hebei earthworm telehandlers introduce you to electric battery powered forklift daily nursing work:
1, engine oil, hydraulic oil, electrolyte tests: first pull out the dipstick, wipe feet after insertion and then pull out the head to check the oil level is between the two tick marks. The working oil tank level should be between the two tick marks; too little oil, the pipeline will be mixed in the air, too much will overflow from the cover. Battery electrolyte also want lies between the upper and lower tick, add distilled water shortage will have the top line.
2. Check tire pressure: shortage should be added to the specified value, confirm no leakage. Check the tire tread and the side without damage, the rim is deformed.
3, brake fluid, water, check: Check the brake fluid is within the scale range, and check whether mixed with air in the brake lines. When adding brake fluid, to prevent dust and water mixed. When water is added to the tank, use clean tap water, if used antifreeze, should bear the same antifreeze. When the water temperature is higher than 70 ℃, do not open the radiator cap when you open the lid, a piece of thin cloth mat, do not wear gloves tighten radiator cap.
4, cleaning the truck dirt, mud and dirt Egypt, key parts are: fork frame and door frame slide, generator and starter, battery electrodes fork columns, tanks, air filter.
5, the brake pedal, the inching pedal, clutch pedal, hand brake check: Each pedal is depressed, check for abnormal slow or jammed. Force the hand brake lever should be less than 300N, confirmed that the hand brake is safe and reliable.
6, check for leaks, the focus is: all fittings, diesel tank, sump, pump the brake, lift cylinders, tilt cylinders, tanks, pumps, engine oil pan, torque converter, transmission, drive axle, main reducer , hydraulic steering gear, steering cylinder.
