The design of the hydraulic lifting platform is unreasonable. When the designer designs the cylinder barrel and rod， if there is a problem with the design size and angle， then there will definitely be problems in the later stage. Therefore， it is necessary to confirm the technical strength of the manufacturer when working on a hydraulic lifting platform; what is the problem with the sound of the oil cylinder of the hydraulic lifting platform? Design drawings to make， the angle of the oil cylinder is slightly deviated， it will cause the friction between the cylinder barrel and the rod which will cause the sound; the seal quality of the hydraulic lifting platform is different， and the seal with excellent material The continuous friction between the parts and the cylinder wall will cause the sound to be very loud and the use of different seals will also affect the sound of the oil cylinder， and long-term wear and tear may scratch the oil cylinder and cause oil leakage， so when the hydraulic lifting platform is used， pay attention to ask the manufacturer what brand and material the seal is used; In some cases of mechanical running-in， it is not ruled out that the above three situations are normal， and there will still be noises. If there is no problem after investigation， then don’t worry. It’s just a running-in problem between mechanical parts. It will disappear naturally.
EvelynMany people think that the strength of the elevator itself is relatively high when using the elevator， so they did not strictly follow the installation method in the manual during the installation process， but they do not know that this will cause increased wear and tear of the parts and inflexible operation， and pay attention to the work The installation precautions corresponding to the environment should not be ignored. Correct installation， use and maintenance of elevators are an important part of ensuring the normal operation of mechanical equipment. Therefore， when you install the elevator， please be sure to strictly follow the installation and use related matters below， and assemble and use it carefully.
The motor winding is short-circuited. When a short-circuit fault occurs in the motor winding， the short-circuit current is much larger than the normal operating current， which increases the copper loss of the winding， causing the winding to overheat and even burn out.
Check the front page of the oil pipe to check whether the skin of the oil pipe of the hydraulic lifting platform is damaged or cracked， and if so，BredaGuide rail type cargo elevator cargo elevator， replace it immediately; secondly， check whether there is any sign of looseness at the connection between the oil pipe and the oil pipe， and if so， tighten it immediately to avoid lifting on the hydraulic lifting platform There is an oil spill in the process， which leads to accidents; what items need to be checked before using the hydraulic lifting platform? Cut off the power first to avoid tragedies such as electric leakage and electric shock)
The hydraulic lifting platform can be divided into: four-wheel mobile type， two-wheel traction type， car modified type， auxiliary self-propelled type， and the lifting height ranges from a meter to s meter.
There are abnormal noises on the hydraulic lifting platform It is a normal phenomenon that the hydraulic lifting platform has abnormal noises， especially for equipment that has been used for a long time. Overloading: Due to overloading the hydraulic lifting platform"s own carrying capacity is overloaded， just like the reason why people will shout when they are overloaded to carry things， so don"t overload!
Are the water cooling and air cooling of the hydraulic station the same?
Where to sell APILow cost: The cost is much lower than that of the scissor-type mobile lifting platform， so when purchasing a lifting platform， you must consider the scope of use of the lifting platform， the frequency of work the load and other factors to choose a lifting platform that suits the work requirements .
Naturally connect the motor to the lift. When connecting， and that the outer flanges of the two are parallel. If the concentricity is inconsistent it must be ensured that the concentricity of the output shaft of the elevator is consistent with that of the input shaft of the motor， it will cause the motor shaft to break or the elevator gear to wear.
It is strictly forbidden for personnel to take the freight elevator to go up and down floors and climb.
Features of hydraulic lifts: According to the working mode， hydraulic lifting platform products are divided into crank arm hydraulic lifting machines， mast type hydraulic lifts， and straight arm hydraulic lifting machines. The hydraulic lift is a replacement product of the folding arm lift (lifting platform) and the scissor lift (lifting platform). It can be widely used in stations， docks， airports， hotels， post and telecommunications， municipal gardens， garages， public building facade decoration， decoration or installation and maintenance of power systems， etc. The lift has the advantages of light weight， self-propelled， electric start， self-supporting legs， simple operation， large working area， especially the ability to cross obstacles for high-altitude operations and the like.
Honest managementAnti-corrosion measures for the body of aerial work vehicles Pay attention to small scratches. The paint surface of aerial work vehicles is often corroded. In addition to common collisions， scratches， small rocks on the driving tires there may also be a peeling paint spot， and a small rust will appear after a long time. Because most of these scars are small， they are easy to ignore. Therefore， check regularly， the engine compartment cover and its surroundings， and once found， go to a professional beauty shop for processing.
The main structure and application of the guide rail elevator adopt closed gear transmission. The large and small gears are made of steel. The design is calculated according to the fatigue strength of the tooth surface， and checked according to the bending fatigue strength of the tooth root. The bracket bracket is used to fix and support all the mechanical parts and some electrical components of the elevator box. It is mainly welded by side plates， connecting pipes and connecting pieces. You can choose any product， and the professional elevator factory has safe and secure transactions. At the same time， in order to reduce the weight of the bracket， many craft holes are designed on the two side plates.
