KMayekThe solenoid valve on the motor should not be adjusted at will. The solenoid valve is pre-adjusted before leaving the factory. After being adjusted at will， the internal pressure will increase or decrease， which results in uneven stress of the hydraulic oil delivery， and uneven table surface. It is recommended to carefully check whether the oil delivery pipe is smooth.
Now the floors are very high. It is very difficult to climb up from the first floor， let alone carry things. For this reason， people invented the elevator， which can easily reach the floor they want to go. But if it rains，Guideway elevator it will be very troublesomeWhat should be done properly after water?
With the progress of the times， the development of science and technology， and the growth of the economy， there are tens of thousands of types of elevators sold on the market. But how to choose mobile lifting platforms? You know， elevators solve some problems of aerial work and provide convenience for aerial work. Now lets follow the editor to see how to choose mobile elevators.
kSecondly， there is no dirt on the friction surface. If there is dirt， it needs to be washed off with gasoline or thinner; The lubrication and hydraulic oil of each part of the equipment reducer， gearbox， replace it in time. The maintenance of wire rope must be carried out in strict accordance with the specification; Check the connection of each part according to the braking rules and regulations. If there is any looseness， tighten it in time. Check the tightness of the connecting bolts of the equipment when the body is under pressure. All connecting shafts should be equipped with cotter pins; Check whether the operation of each mechanism is normal，Guideway elevator whether there are noises and faults according to regulations， and remove all faults in time; When installing，Small elevator villa elevatorFixed hydraulic lifting platformHow to achieve dual qualitative change disassembling and adjusting the rotating mechanism of the equipment， it is necessary to pay attention to that the reducer and the gear center line should be parallel， and the meshing clearance should be appropriate; Conduct a comprehensive inspection of the equipment regularly to check whether the wires and cables are damaged， and whether the motor is overheated. Replace it in time to eliminate the fault before continuing to operate; The bearing lubrication of the motor shall be ensured. Each box， distribution box and brush shall be kept clean. The travel switch contact point of each safety device must be safe and reliable.
RRemove and disassemble the lowering valve of the hydraulic elevator blow the plunger clean with compressed air， and then install it again.
CQuality AssuranceThe loading and unloading mobile boarding bridge has become a very visible structural form in modern logistics sites. It is the starting point and end point of the enterprise logistics chain， and a loading and unloading operation platform for enterprises to quickly and turnover products and goods. The height of the loading and unloading operation platform is fixed， but the height of the carriage to and from the ground does not always form a certain height difference or gap between the transport vehicle and the loading and unloading platform. As a result，Scissor lift_ Hydraulic lifting table_ Guide rail lift - scissor lift manufacturer the forklift can not enter and exit the transport vehicle to directly load and unload goods. Use the boarding bridge to provide reliable connection. It enables the forklift truck to enter and exit the transport vehicle quickly for loading and unloading.
aGRegularly add lubricating oil to maintain the lift: during the use of the lift， the friction between various components is also relatively large due to the heavy load， especially the lift chain and the lift pivot pin. It is necessary to ensure that the appropriate amount of lubricating oil is added before each use to ensure that the operation is flexible and not blocked. If the elevator is running， once“ appears; Squeak” It can be basically concluded that the friction noise is due to the lack of lubricating oil in the elevator. It is necessary to stop working immediately and find out the reason. It is easy to cause unpredictable hidden dangers. Point summary: it is not allowed to add lubricating oil regularly to maintain the elevator.
Just like the failure of the traveling part of the lifting platform， the operator must master the common sense of equipment maintenance failure， so that when the failure occurs， it will not appear too flustered. Generally speaking， the common faults of the traveling part of the lifting platform are divided into:; The bearing bush is burnt， the axle box bearing is burnt the traction motor bearing is burnt， the tyre is loose， and the crack is damaged. Lets share the solution with you.
Check the connection of each part of the hydraulic lift frequently， and tighten it if it is loose. The tightness of the connecting bolts of the engine body shall be checked when the engine body is under pressure. All connecting shafts must have cotter pins and be fully opened.
