After lifting to the target height， it automatically levels with the floor through a limit switch. And there are various forms (single track， double track， four track， multi track).
PFirstly， it is necessary to maintain regular maintenance. After a certain period of time the paint of the elevator will automatically oxidize with oxygen in the air， causing aging. When using the elevator equipment， it is necessary to pay attention to storage and avoid exposure to the outdoors. It is strictly prohibited to place it outdoors in summer or rainy days for exposure to sunlight or rain.
LPromotionSo how do we choose the suitable lifting platform for ourselves? Here，Lifting platform - elevator - hydraulic lifting platform - elevator manufacturer the editor will share with you:.
fYThe wear rate is fast， and due to factors such as processing， assembly， and adjustment of new machine components the friction surface is rough， the contact area of the mating surface is small， and the surface pressure condition is uneven. During the operation of the machine， the concave and convex parts on the surface of the parts are intertwined and rubbed against each other. The metal debris that falls off from the grinding process， in turn， acts as abrasive and continues to participate in friction， further accelerating the wear of the mating surface of the parts. Therefore， during the running-in period， it is easy to cause wear on components (especially the mating surface)， with a fast wear rate. At this point， if overloaded， it may cause damage to the components and lead to early failures.
There are many operational errors， and due to insufficient understanding of the structure and performance of the machine (especially for new operators)， it is easy to cause malfunctions and even mechanical accidents due to operational errors. How is a cargo elevator calculated? A cargo elevator is a type of lifting and lifting mechanical equipment that can manually operate the systems buttons to transport goods up and down. The lifting height of the cargo elevator ranges from meter to meters， and special specifications of cargo elevators can be customized according to user requirements According to the type， it can be divided into:; Scissor fork type cargo elevator and guide rail type cargo elevator. Guide rail type elevator is a non scissor fork type cargo elevator， mainly used for the transportation of goods between two or three floors of workshop buildings， steel structure workshops， hotels， basements， and warehouses without pits or machine rooms. Scissor fork type cargo elevators need to be prepared with pits in advance. When installing the cargo elevator should be fixed and connected in the pit， and can be used by connecting the power supply The lifting cargo elevator utilizes hydraulic power units to generate pressure during operation， which drives the hydraulic oil cylinder as the main power to raise and lower the lifting cargo elevator platform. When a guide rail type hydraulic lifting cargo elevator malfunctions， it can immediately stop running， with high safety and stability. The driving of the hydraulic power unit makes it have strong load-bearing capacity and smooth lifting， which can achieve the transportation of large tonnage goods
The lifting platform is composed of a power unit and an oil cylinder. The power unit is equipped with four adjustable holes during production， and the hydraulic oil flow rate is adjusted by adjusting the motor speed or the electro-hydraulic proportional valve. From these two aspects， the power unit is adjusted to adjust the lifting speed of the lifting platform.
Convenient and efficientaThe wear rate is fast and due to factors such as processing， assembly， and adjustment of new machine components， the contact area of the mating surface is small， and the surface pressure condition is uneven. During the operation of the machine， the concave and convex parts on the surface of the parts are intertwined and rubbed against each other.

VProduct installation instructions: The low height is between -mm， there is no need for an upper lifting point which is particularly suitable for situations where the top floor height cannot meet the installation requirements of the computer room and other difficult to solve narrow spaces. Diversified forms.
，All connecting shafts must have split pins and must be fully opened.
pBolognaDuring service hours， drivers are not allowed to leave their positions without authorization. They must close the hall door when leaving. The driver also has the ability to supervise that the load of the suspension box will not exceed the additional weight. It is not allowed to ship flammable， explosive， and other dangerous items. Before starting the hydraulic cargo elevator， the door of the hydraulic cargo elevator must be closed and sealed. It is prohibited to move the cargo elevator smoothly when the door is open.
aSThe working environment of the lifting platform.
Leakage occurs due to looseness， vibration， and the influence of heat on the sealing surface and pipe joints of the machine; Some casting， processing and other defects are difficult to detect during assembly and debugging， but due to vibration and impact during the operation process， these defects are exposed， manifested as oil (water) leakage. Therefore， leakage is prone to occur during the running-in period. Poor lubrication， due to the small fit clearance of newly assembled components and the difficulty in ensuring the uniformity of fit clearance due to assembly and other reasons， lubricating oil (grease) is not easy to form a uniform oil film on the friction surface to prevent wear. This reduces lubrication efficiency and causes early abnormal wear of the components. In severe cases， it can cause scratches or bite on the friction surface of precision fitting， leading to the occurrence of faults.
