Principle of electric elevator rotary valve: When the electric elevator rises, the rotary valve will automatically open. To close the plug valve, and then turn the transmission handwheel to lower the plug and achieve sealing.
In addition to ground protective fences, low level doors can be used. Low level doors should meet the following requirements: the height of the door should be between 1m and 2m. And there should be at least protective railings, a half height middle crossbar and a toe board at least 150mm above the ground.
Pwotsk.Try to use this equipment in areas with wind force less than level five, and avoid using it when the wind force is too strong to avoid accidents.
As a material loading and unloading equipment recognized by customers in the lifting platform, the guide rail hydraulic lifting platform is superior in terms of product, civil engineering, and operating costs. The editor of the electric elevator will provide a detailed analysis: the advantages of the product are that the equipment bears a large load,PwotskElectric screw elevator, can achieve multiple points, except for the gap between the lower part of the door that should not exceed 35mm, any through-hole and opening size related to the distance between any door and adjacent moving parts, as well as the gap around the door or the gap between parts, should comply with the provisions of Table 4 of GB 23821-2009.
The landing door should meet the requirements of the specifications and achieve standardization.
Manual pump: When the system malfunctions the manual pump can be operated to pump high-pressure oil to raise the car to the nearest floor position

The editor of the electric elevator will provide a detailed analysis: the advantages of the product are that the equipment bears a large load, can achieve multiple points,PwotskDecoration electric elevator, and can be controlled up and down floors to achieve safe use.
Mobile electric elevators are divided into: four wheel mobile lifting platform, two wheel traction lifting platform, car modified lifting platform, manual lifting platform, manual lifting platform, and AC/DC dual purpose lifting platform
Every theater is a public place with a large number of people, and safety considerations should be taken into account in stage design. According to relevant national regulations, in order to prevent accidents caused by the crushing of electric elevators or improper control by drivers. Electric elevators should be equipped with the following necessary safety devices to ensure that the car of the electric elevator stops rising or falling in a timely manner.
Standard requirements.News Abstract: The development of the lifting platform industry will continue to grow in recent years! With the continuous development of electric lifting machinery for high-altitude operations in recent years, the products of electric lifting platform vehicles have been continuously improved, and various new technologies and materials have emerged, making the further development of lifting platform vehicles possible.
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.
Flat screw mechanical electric lifting mechanism: The lifting platform of this structure has the advantages of small civil engineering coordination,PwotskInstallation of electric elevators for fire protection, shallow foundation pit required, large stroke stable operation, low noise, accurate positioning, and low cost. Adopting a horizontal screw drive and a scissor fork structure to achieve the lifting motion of the table, it can be stopped arbitrarily within the range of travel.
When the wall bracket adopts non matching standard products, design calculations should be carried out.
Good reputation.The use of standard section connecting bolts should comply with the user manual and specification requirements.
And the decoration team is also using aluminum alloy electric elevators. What safety considerations should we consider during the use process? Many manufacturers have not clearly indicated it. Today, the mechanical editor will talk to you about aluminum alloys
Secondly, the lifting platform is driven by electrical energy and lifted by the hydraulic system. During operation, it is necessary to avoid irregular operations. To ensure the normal and orderly operation of the lifting platform and achieve the ideal unloading level, timely inspection of various functions is essential.
