Burgess gradbaSecondly, 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 2 to 3 times to ensure that the air in the oil cylinder is completely discharged, maintain sufficient space, and ensure that the lifting platform can be lifted to the rated lifting height.
Drivers of construction electric elevators should hold special construction operations and are not allowed to operate without a certificate.
Burgess gradbach.A lifting platform with specifications ranging in height from 1 meter to 20 meters.
When the wall bracket adopts non matching standard products, design calculations should be carried out.
.Safety performance: Electric elevators not only have the safety device of traditional traction elevators, but also have an overflow valve to prevent excessive system pressure during upward movement
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
When the door is closed, 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,Burgess gradbachElectric hydraulic platform elevator, 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.
Installation and dismantling personnel and drivers should hold certificates to work.
The safety overtravel of limit switches and upper limit switches should comply with regulatory requirements.
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.
demand.The spacing between wall brackets and the height of guide rails above the high attachment point should comply with the requirements of the user manual.
Mechanical devices controlled by cage movement should not be used to open or close the landing door.
Electric elevators used in various places.
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.
Sampling inspection.The verticality of the guide rail frame should meet the requirements of the specifications.
Check the starter potential when the lifting table is not raised or the voltage is too low when the motor load is working. Voltage hydraulic range allowed&
When the horizontal distance between the edge of the cage and the edge of the landing or between the cage and the landing door is greater than 150mm and there is no effective protection from other structures, the side protection device for the landing entrance should be equipped.
Burgess gradbach.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 extended stage, a T-shaped stage, or a hall.

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.
