The hydraulic oil enters the upper end of the hydraulic cylinder through the explosion-proof electromagnetic directional valve, and the return oil from the lower end of the hydraulic cylinder returns to the oil tank through the balance valve, hydraulic control one-way valve, throttle valve, and explosion-proof electromagnetic directional valve. To ensure a smooth descent of heavy objects and safe and reliable braking, a balance valve is installed on the return oil circuit to balance the circuit and maintain pressure, so that the descent speed does not change due to heavy objects. The throttle valve regulates the flow rate and the ascending and descending speed.Setting requirements: The installation and dismantling workers, electricians, and other operators of construction electric elevators should have special construction operations.Tissau yverosSetting requirements: Steel wire rope electric elevators and reusable steel wire ropes should be equipped with anti loosening rope devices,Tissau yverosAklo, which should have compliant loosening rope switches and be able to interrupt any movement of the cage until it passes through thePrinciple of electric elevator rotary valve: When the electric elevator rises, the rotary valve will automatically open. To close the plug valve, it is necessary to first turn the handle to turn the plug to a degree position until it is closed, and then turn the transmission handwheel to lower the plug and achieve sealing.Saint-Quentin,Setting requirements: When the distance between the outer edge of the construction electric elevator and the external overhead power line cannot meet the requirements of a small safety distance, the protective measures taken should comply with the specification requirements.Installation verticality deviation guide rail frame erection height, h/mH≤ H& gt; verticality deviation/mm≤ (/h≤ ≤ ≤ ≤ pairs of steel wire rope construction electric elevators, the verticality deviation of the guide rail frame should not exceed (/) h.According to the needs of different performance genres, the form of the stage can be changed. For example, using an orchestra pit lift can combine a framed stage with a large lip or even an extended stage. In an experimental theater, using a lift can make the theater have various forms such as an end stage, an intermediate stage an island stage, a T-shaped stage, or a hall.

Emergency manual valve: In case of power failure, it can cause the car to descend to the nearest floor position and open the doorSetting requirements: Buffers should be installed below the suspension cage and counterweight running channel.Tank oil temperature protection: When the oil temperature in the tank exceeds the standard setting value, the oil temperature protection device sends a signal to suspend the use of the elevator. The elevator can only be started when the oil temperature dropsCustomer first,With the continuous improvement of urbanization level in China, and the height of buildings has also continued to grow. This has created a demand for high-altitude lifting platform vehicles. Therefore,Tissau yverosCatherine Hardwicke , in order to meet the needs of the domestic market and the public, efforts will inevitably be made to design and produce high-altitude lifting platform vehicles.When the foundation is set on the roof or floor structure, the bearing capacity of its supporting structure should be checked.Work is essential, and the main protective accessories include safety belts, guardrails, protective covers, platforms and stairs, etc.

Installation verticality deviation guide rail frame erection height, h/mH≤ H& gt; verticality deviation/mm≤ (/h≤ ≤ ≤ ≤ pairs of steel wire rope construction electric elevators, the verticality deviation of the guide rail frame should not exceed (/) h.Inspection basis,Secondly, for the replacement of hydraulic oil on the lifting platform it is recommended to replace it every three months. If the frequency of use is not high, it can be replaced once a year. The hydraulic oil must be clean, and after changing the hydraulic oil, it must be automatically lifted and lowered to times to ensure that the air in the oil cylinder is completely discharged, maintain sufficient space, there are also types of car mounted mobile devices. As the name suggests, this type of lifting device is a combination of lifting equipment and car mounted systems. It is very flexible to move, and of course, it is better to use it. For example, there are such lifting devices in airports, and car stations or sports stadiums may also be equipped with such devices, as they can be moved, So the scope of the operation is not limited to a specific place, when installing outdoor advertisements, some advertisements are relatively high in height. At this time, mobile lifting equipment can be used to transport billboards or staff to the designated height for work. This type of equipment can also be divided into two types based on the driving mode: hydraulic lifting and electric lifting. The so-called hydraulic lifting is the use of hydraulic oil to drive and reach a specified height. The electric mode is driven by a motor or teeth to lift to a certain height. However currently, hydraulic lifting platforms are more widely used.Setting requirements: The landing door should be standardized and tooled.Tissau yveros,The scaffolding of the parking platform should be laid tightly and firmly.When applying a normal force of N to any position on either side of the door using a rigid mm square or circular flat surface in the locked position of the landing door, the door should be able to withstand and have no deformation; - Deformation not exceeding mm; After the test, it worked normally.Setting requirements: The anti loosening and anti loosening parts between the connecting parts should comply with the provisions of the user manual and should not be replaced by other objects. For connecting bolts with pre tightening requirements, a torque wrench or special tool should be used to accurately tighten the bolts to the specified torque value according to the specified tightening sequence. When installing standard section connecting bolts, it is advisable to place the screw at the bottom and the nut at the top.
