Talking about the daily maintenance and use of hydraulic lifting platform motors. Overloading is strictly prohibited， as overloading can increase the burden on the motor and in severe cases， cause the motor to burn out.
Once the freight elevator malfunctions the maintenance unit shall arrive at the site within the specified time (the specific time is not specified in Beijing， but within minutes).
PearlSecondly， there should be no dirt on the friction surface. If there is any dirt， it needs to be washed off with gasoline or thinner; The reduction gearbox， gearbox， external meshing gear， and other parts of the equipment， as well as the hydraulic oil， must be tested according to the requirements in the table; The correct maintenance method for hydraulic guide rail elevators is to regularly check the steel wire ropes in various parts for any breakage or looseness. If this phenomenon is found， it should be tightened in a timely manner. The tightness of the connecting bolts of the equipment should be checked when the body is under pressure. All connecting shafts should be equipped with split pins; According to regulations， check the normal operation of each mechanism， whether there is noise or malfunction， and promptly eliminate all faults; When installing， disassembling， and adjusting the rotating mechanism of the equipment， it is important to ensure that the centerline of the reducer and gear is parallel， and the meshing clearance is appropriate; Regularly conduct a comprehensive inspection of the equipment to check if there is any damage to the wires and cables and if there is any overheating of the motor. Replace and eliminate the fault in a timely manner before continuing operation; Ensure the bearings of the motor， and ensure that all boxes， distribution boxes，PearlMobile hydraulic lifting platform， and brushes are properly protected
Each box， distribution box， and dust on electrical equipment should be quickly swept away.
KardzaBefore using the machine， the staff should carefully inspect the hydraulic and electrical systems to ensure that there are no leaks or bare leaks before use.
Mobile elevators are generally used in skyscrapers where electric elevators are used， as there is no need to stop midway， so fast elevators are needed. First go to the high-rise sky lobby (high-rise elevator lobby， Skylobby) from the ground， and then transfer to the ordinary elevator to the destination. Some new elevators use elevator pre calling systems， which can pre call designated floors in the lobby. These passenger elevators can be decorated beautifully according to customer needs. Some passenger elevators are also equipped with air conditioning and television， while others are set up in the cabin， so that customers can enjoy the scenery outside while riding.
Hydraulic oil should be kept clean and replaced every months; When repairing， maintaining， and cleaning the elevator， be sure to support the support rod.
When encountering overheating in the electric motor during daily maintenance of the elevator it is necessary to quickly park the car， remove obstacles， and then continue running. The motor bearings should be smooth and excellent.
The hydraulic pipeline is probably congested. The hydraulic pipeline is also a particularly important key， checking whether the hydraulic pipeline is smooth. Focus on checking whether there are signs of congestion or jamming in various hydraulic valves， including one-way stop valves， electromagnetic directional valves， proportional control valves， overflow valves，Pearl20 meter hydraulic lift， the hydraulic valve should be cleaned or replaced in a timely manner， as the hydraulic oil may deteriorate or contain impurities. After the hydraulic oil is permanently used， there may be impurities or deterioration in the hydraulic oil. Take a sample for inspection to see if it contains fluid particles， discoloration， or odor. If necessary， replace the hydraulic oil.
Elevators are now very popular among people and can easily transport goods to high-rise buildings. Among them， hydraulic elevators are more popular among people， and people can choose the one that suits them according to their actual situation. However， during normal work， it is important to pay attention to the lifting speed of hydraulic elevators and avoid making mistakes. So what factors will affect the lifting speed of hydraulic elevators?
A complete range of productsThe lifting force of the scarifier is not strong or the lifting force is weak: the pressure regulation of the overflow valve does not meet the need to adjust the pressure to the required value; Refer to cleaning item above for leakage in the oil cylinder; The directional valve is stuck or leaking internally; The oil level is too low， and the oil inlet filter is blocked; The fuel supply pump has drawbacks; Check the wear and tear of the one-way valve core and valve seat， and check if the one-way valve spring is tired or deformed.
The daily maintenance of guide rail type lifting equipment should pay attention to regular inspection and maintenance， eliminate hidden dangers， eliminate faults， and achieve these benefits for improving work efficiency， extending equipment service life， and ensuring the safety performance of the elevator.

In our daily life， hydraulic cargo elevators are increasingly widely used and loved by customers. As a lifting tool， the maintenance of hydraulic cargo elevators should not be careless. Below， the editor will introduce the daily maintenance of hydraulic cargo elevators.
How much is itWhat are the common faults of hydraulic lifting platforms? The hydraulic lifting platform"s oil cylinder is severely damaged， and uneven damage to the inner sealing ring or obstacles inside can easily cause uneven stress， resulting in uneven lifting height of the oil cylinder. It is recommended to carefully check whether the oil cylinder is normal.
The current should exceed the rated current， and even cause the motor to stop on its own. If the shutdown time is slightly longer and the power supply is not cut off， the winding will not only overheat severely but also burn out. When a star connected motor is mistakenly connected into a triangle， or a motor with multiple coil groups connected in series into a branch is mistakenly connected into two parallel branches， it will cause the winding and iron core to overheat， and in severe cases， the winding will be burned out.
The inconsistent rotation axis of the support rod in the middle of the hydraulic lifting platform results in the lifting platform being unable to function properly， causing serious damage to the platform and causing the table to tilt. Please carefully check that the general shear type high-altitude work platform was not strictly tested for tilt before leaving the factory， and was put into the market， causing many accidents. For small enterprises， they are not very concerned about this aspect of tilt detection， This is also why there are such a large number of lifting equipment with this problem. The problems with the oil cylinder and power unit system are often due to insufficient power and substandard oil cylinder quality， the same goes for them. Of course， during the internship， there may still be some questions about the elevator， but without contact， simply mastering some specific skills can effectively handle these questions.
Outdoor elevators and factory cargo elevators are heavy lifting mechanical equipment. Outdoor elevators are used for transporting goods between floors of buildings，PearlFixed electric hydraulic lifting platform， and are specialized hydraulic cargo elevator products. They are mainly used for transporting goods up and down between various working floors; Vertical garage and car lift between garage floors. The hydraulic system of the product is equipped with anti fall and overload protection devices， and operation buttons can be set on each floor and lifting platform workbench to achieve multi-point operation.
