Check if the usage period of the speed limiter has expired. If it exceeds the usage period， and large quantities of goods must be transported in batches using cargo elevators.
lJiexiuThe structure of the guide rail lifting platform itself must meet the stability requirements. No instability failure is allowed， that is， the working stress of slender members should not exceed the critical stress.
Many times， after installing hydraulic cargo elevators in factories， floors，Fully automatic scissor fork lifting platform docks and other places，ManhattanOutdoor guide rail type lifting platformJinjiu is approaching price fluctuations and rising there may be some adverse reactions and problems in the early stage. Below， Yakalis editor summarizes some common problems with hydraulic cargo elevators and provides some statements on how to solve and prevent these problems.
CPerimovFrom the current situation， hydraulic elevators produced in China have varying degrees of oil leakage， which not only causes significant resource waste， but also affects the normal use of users. The phenomenon of oil leakage exceeding the specified indicators can generally be detected immediately due to external leakage， mainly reflected in the pressure drop of the elevator， sudden changes in speed， and serious accumulation of oil on the ground or machine surface， The equipment needs to be frequently refueled to restore its previous operating height. Once there is an oil leak，Fully automatic scissor fork lifting platform it must be shut down for maintenance. Forcible operation will only damage the machine and cause serious air pollution. We should avoid the phenomenon of hydraulic lifting platform oil leakage to minimize the harm.
FsThe lifting stage is a high-altitude operation equipment， and prolonged use can cause loose connections between some components. So in order to ensure the personal safety of construction workers， it is necessary to regularly inspect the lifting stage and tighten any loose components. The lifting stage is a high-altitude operation equipment， and prolonged use can cause loose connections between some components. So in order to ensure the personal safety of construction workers， it is necessary to regularly inspect the lifting stage and tighten any loose components. The interference and hazard analysis of the frequency conversion speed regulation construction elevator circuit is becoming increasingly widespread in the development of technology today. Variable frequency speed regulation is characterized by stable start and stop process， reduced mechanical shock， increased comfort of passengers， and improved service life. At the same time， it can also adjust the speed by changing the power supply frequency to save electric energy，Improve work efficiency，Fully automatic scissor fork lifting platform but there may be interference in the use of variable frequency speed control systems， which often leads to safety accidents of construction elevators.
Serious oil leakage from manual pump and gear pump; The gear pump is damaged，ManhattanOutdoor guide rail type lifting platformJinjiu is approaching price fluctuations and rising and the oil pumped out has no pressure; Insufficient hydraulic oil; Open circuit; Filter blockage; The action of the support valve or directional valve fails; Insufficient input voltage of electromagnetic coil; The electromagnetic coil is burnt out; The valve core is stuck. These are all factors that cause the lifting platform workbench to be weak or unable to lift. The solution is to replace the sealing ring， replace the gear pump， add enough hydraulic oil， repair the electrical system， replace or clean， repair or replace.
Check all standard sections and diagonal support connection points. Together， check the fastening bolts of the gear rack， adhere to the cleanliness of the motor cooling wing plate and organization
sUsers purchase a lifting platform in the hope that the equipment can bring them a return. The technology mastered by enterprises is to improve the return of the equipment. No matter how advanced this technology may be，Lifting platform - elevator - hydraulic lifting platform - elevator manufacturer if it cannot improve the users return， it cannot be recognized by the market. So enterprises need to determine the direction of technological research by improving user returns， more accurately and effectively meeting the needs of the market and users， in order to have a competitive advantage. The working temperature of the hydraulic oil for the elevator is too high， which is detrimental to the working components of the hydraulic system，At the same time， it will accelerate the oxidation of hydraulic oil. The working temperature of general mechanical hydraulic systems should be below ℃， while the working temperature of engineering mechanical hydraulic systems should be below ℃. The working temperature of hydraulic oil mainly affects the cooler performance of the hydraulic system， the reasonable amount of hydraulic oil in the entire hydraulic system， and the load and speed of hydraulic system components.
VIn the early stage of installing the lifting platform， it is necessary to carefully prepare a special construction plan and conduct technical testing on the installation personnel to ensure that the basic level of installation and all aspects meet the requirements of use. In addition， it is necessary to keep the roads of the lifting platform unobstructed and have sufficient space， which are all necessary preparations in the early stage.
ZRespect for customersThe lifting platform welding and cutting equipment should have good isolation and protection devices， such as photoelectric leveling switches， deceleration switch stages safety gear， guide rails， guide shoes， etc.， may vary due to speed. Of course， this must be related to how the specific elevator configuration is classified.
?? When the construction supervisory department fulfills its safety supervision and inspection responsibilities， it shall be ordered to evacuate workers from the hazardous area or temporarily stop construction. In the work of hazard investigation and control， the investigation shall be serious， the rectification shall be resolute， and the results shall be consolidated.
Check what materials are used for the main components of the equipment whether the specifications are qualified， and whether they meet your own needs. Are all safety devices in place.

The editor will explain the safety operation management regulations for the lifting stage to everyone: . Every year， an annual inspection of the cargo elevator is required to ensure the safety of the lifting stage.

In the design of hydraulic elevators， it is necessary to decompose the functions of the equipment required by the plan. It is necessary to understand which mechanisms can be used to complete these functions， how these mechanisms are combined and configured， and how to organize the installation and debugging of the equipment. In addition， designers should also consider the operation mode of the cargo elevator and which power sources should be used， The transmission method to be adopted， whether the technical parameters are correct， and the requirements of the product are all indispensable in all aspects of the appeal， there are more and more types of lifting platforms in our daily lives. The common one is aluminum alloy lifting platforms. So， what are the principles of aluminum alloy lifting platforms? Next， lets introduce ourselves to you.
zJiexiuFirstly， lets take a look at the characteristics of simple cargo elevators: simple cargo elevators are mainly composed of a hoist and a steel wire rope. The hoist is connected to the power supply and the cargo elevator is lifted up and down， achieving the lifting of goods. Generally， a three ton cargo elevator uses a ton hoist and a # steel wire rope， which exceed the actual load capacity very little. Once the hoist of the cargo elevator malfunctions， or stops operation， or loses control， the consequences of the steel wire rope breaking are even more unimaginable.
