the following situations occur:
a) insufficient charging: charging less long-term, it will seriously affect the battery life; b) Overcharge: Overcharge will cause a lot of water in the electrolysis of the electrolytic solution, higher temperature, from the positive electrode, the negative electrode of the battery increased precipitated gas cathode, anode active material loose structure, reducing battery life; c) over-discharge: after over-discharge in the positive and negative lead sulfate layer structure generated more dense, while charging the active substance is difficult to recover; severe over-discharge of the battery can also cause an individual turn pole. 2 battery use, there will be hydrogen evolution, especially during charging and precipitation greater period of time after charging the end, therefore, it is timely to charge the battery room ventilation, and strictly control the hydrogen content in order to ensure safety. 3 battery use, if the electrolyte temperature is too high, it will exacerbate the precipitation of hydrogen, lower bonding strength of the active material and the grid, increase the electrolyte to the plate corrosion, seriously affecting battery life and cause the rubber seals over early aging. 4 cell surface should be clean, dry, to promptly clean up the outer surface of the battery falls, tie bars and bolts of dust and measurement process on the drop of electrolyte in the battery cover to ensure good battery insulation properties. 5 battery use, the battery once every two months to respond to a balanced charge. 6 measuring not less than once a week to check the battery's voltage, electrolyte density and temperature. To fully understand the status of the battery pack, always check once a month, the total measurement. Inspector General of content: the connections are tight, electrolyte level, density is normal, the voltage is balanced, etc., especially smart charging batteries, often neglect to check the battery, resulting in problems of individual cells was not found , thus affecting the performance of the whole battery. 7 In the process of inspection and measuring the battery, prohibited crushes, collision battery cover, battery cover, etc. liquid injection parts to prevent damage. Maintenance and repair of mechanical parts Is recommended for six months (or 600 hours) Replace the hydraulic oil, use less time should be replaced every year. Replace the hydraulic oil can be easily realized by the following method: Ensure that live rack in the lowest position and remove the lower cylinder hose fittings and placed in a container, the operating handle to make lifting and emptying the oil pump is running inside the tank. Use YA-N32 hydraulic oil or similar species. If it is within the low temperature cold, it is recommended the use of YH-10 hydraulic oil, for two to three times after lifting the system will not have air, the device can work if the lifting height should be less than the supplement of hydraulic oil. ==================================================================
dirty surface will cause battery leakage
long1 , level : below the rated level , the battery will shorten the life of the battery and the electrolyte will lead to too little heat damage , therefore, must always pay attention to the electrolyte solution is sufficient. longlonglonglong2 , terminal , wire, cover : You must always check the battery terminal junction with wire connections oxidation caused by corrosion , also check whether the deformation of the cap , if there is fever phenomenon . longlonglonglong3 , Appearance: dirty surface will cause battery leakage, so that the battery surface should always be clean and dry . longlonglonglongSecond, the maintenance longlonglonglong1 , add water : according to the level required to add distilled water , do not add water to prolong the interval and add distilled water too much , too much water will overflow cause electrolyte leakage . longlonglonglong2 Charge: battery charging process will produce gas charge should be kept ventilated place , no fire around and charging oxygen, acid gases generated in the process will have an impact on the surrounding . During charging charging plug will disconnect the arc , after charging machine off, unplug it before . After charging the battery stranded around a lot of hydrogen , does not allow any open flame , should open the cover on the battery charge . longlonglonglong3 , terminal , wire, cover maintenance: must be specified by the manufacturer of professional and technical personnel before proceeding . longlonglonglong4 Clean : If dirty , you can clean it with a damp cloth , if very dirty , it is necessary to remove the battery from the car after washing with water to make it dry naturally .
  Electric cars has improved cargo handling efficiency
longlonglonglongElectric cars has improved cargo handling efficiency , reduce labor intensity characteristics , widely used in workshops, laboratories , warehouses, upstairs operations, narrow channel operations, long-distance transport . longlonglonglong1 , a drive wheel suspension system : a drive wheel as the load pressure of the severity change, the machine can be self- damping system according to the severity of shock goods , especially when the body is at a bad road conditions , has a significant effect.

the surface of artificial manipulation of the only two forward gears
Loaders, forklifts, bulldozers, technological development , and promote the development of domestic transmission components . The most wide range of large loader transmission component parts are basically starting in 1970 Liugong developed in collaboration with the Tiangong successful ZL50 ( then called Z450) wheel loader transmission . Its transmission by a twin-turbo torque converter plus simple planetary power shift transmission components. It can be said that China's electric forklift industry , especially for China's first national brand one of the most beautiful loaders cause great contribution. It 's great contribution lies : in the seventies on the realization of a single- lever control speed , power shift , and the surface of artificial manipulation of the only two forward gears , one reverse gear, there are actually four forward gears and two reverse block, is automatic , without manual manipulation . Therefore, only one job is operated by the driver block , simply driver operation forward, backward , but no shift , so manipulation is very flexible , convenient, energy , and thus high efficiency . Coupled with simple planetary gearbox row, structure , oil are relatively simple, especially for the seventies and eighties China 's manufacturing standards. Therefore, the dual variable appears
