(For SC/ type， first install the cage and then install the drive plate).
The design of the hydraulic lifting platform is unreasonable. If the designer has problems with the design dimension and angle when designing the cylinder barrel and piston rod， then there will be problems in the later stage. Therefore， it is necessary to confirm the technical strength of the manufacturer when purchasing the hydraulic lifting platform; What is the noise of the hydraulic lifting platforms cylinder? If the hydraulic lifting platform is not manufactured in strict accordance with the designers design drawings in the process of manufacturing the machine， and the angle of the cylinder is slightly deviated，fork lifter it will cause the friction between the cylinder barrel and the piston rod resulting in the noise; The quality of the seals of the hydraulic lifting platform will also affect the sound of the cylinder if the seals are used differentlyConstant friction between the seal and the cylinder wall will cause loud noise， and long-term wear may cause oil leakage due to the cylinder scratch. So when purchasing the hydraulic lifting platform，Small indoor elevatorHydraulic lifting platform fixed typeWhat are the survival rules of the industry pay attention to ask the manufacturer what brand and material of seal is used; Some situations of mechanical running-in do not rule out that the above three conditions are normal， but there will still be noise. If there is no problem after troubleshooting， then dont worry. It is just the running-in problem between mechanical parts. If you run more times， the noise will naturally disappear.

It has lifting balance， easy operation， and can enter the general lobby. It can enter and leave the elevator at will， with less power consumption，Scissor lift_ Hydraulic lifting table_ Guide rail lift - scissor lift manufacturer no pollution， and no damage to the ground when working. It can be used for wall work and exploration work， without dead corners. The single-column aluminum alloy electric elevator is equipped with gantry cross-frame accessories， halls， churches， etc.
HWhen personnel enter the lift table for maintenance， the lift must be hoisted to prevent casualties caused by the sudden fall of the lift table.
QLets seeAlways check all wires and cables for damage. The damaged parts shall be bound up and replaced in time.
sJThe boxes and distribution boxes are usually kept clean， and dust on the electrical equipment should be cleaned quickly.
Loose fixing screws of the motor: the motor fan will make a noise when it rotates. If the screws fixing the motor are loose， coupled with its own vibration the motor will collide with other parts， so it will make a noise; The joints of each pin shaft are dry， lack of lubricating oil， and the hard friction between iron parts and iron parts not only damages the parts but also makes abnormal noise. Therefore， the small editor should emphasize again， pay attention to timely maintenance and frequently add lubricating oil; The hydraulic lifting platform does not riseIf there is air in the hydraulic oil when the pressure lifting platform does not rise， open the vent hole， and then tighten it after the air is discharged; Hydraulic oil solidification: replace the hydraulic oil; Oil leakage: check whether there is oil leakage at each oil pipe interface. If there is oil leakage， replace it in time; Motor reverse: check whether the wiring is wrong; (If you do not understand the electricity， contact the manufacturer of the hydraulic lifting platform in time)
Check whether all travel switches are loose. If yes， tighten them. Pay special attention to the ultra-high protection stroke of the hydraulic lifting platform to avoid accidents caused by the equipment exceeding the high safety height; Pin shaft Check whether the pin shaft (ear pin shaft and center pin shaft) is dry. If some are dry， inject corresponding lubricating oil immediately; Check whether nuts， nuts， screws， etc. are loose on site， and if so， immediately reinforce them; Ensure that the hydraulic lifting platform lifts smoothly; Outrigger (for aerial work platform)
wholesalerjCheck the hydraulic oil quality and level. When the lifting platform is raised to a high level， the hydraulic oil level should be -mm higher than the bottom of the oil tank. When the color of hydraulic oil becomes dark， the oil is sticky， or there are foreign matters such as gravel in the oil，The hydraulic system of the lowering platform shall be checked for the hydraulic and pipe connections. Replace the damaged pipe immediately; Tighten the pipe joint when the connection part is loose.
