RevitalizationElectric automatic elevatorThe scope of application will be improved

The list of materials for making landing doors is as follows: Table 1: List of materials for making landing doors. Landing doors should be installed at the entrance of each landing station, and the landing doors should function properly.

The scaffolding of the parking platform should be laid tightly and firmly.

Revitalization.Lowering platform, vehicle mounted lifting platform,RevitalizationFloor electric elevator, self-propelled lifting platform, diesel engine curved arm self-propelled lifting platform folding arm lifting platform, aluminum alloy lifting platform, and special

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, 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.

.Speed limit wire rope switch. When the speed limit wire rope trips or breaks. Make the electric elevator unable to start.

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.

The L distance depends on the selected wall mount model.

The hydraulic oil forms a certain pressure by the vane pump and enters the lower end of the hydraulic cylinder through an oil filter,RevitalizationUsed electric elevator, explosion-proof electromagnetic directional valve, throttle valve, hydraulic control one-way valve, and balance valve, causing the hydraulic cylinder to move upwards and lift heavy objects. The return oil at the upper end of the hydraulic cylinder returns to the oil tank through the explosion-proof electromagnetic directional valve,RevitalizationUsed electric elevator platform, and its rated pressure overflow valve is adjusted. The pressure gauge observes the reading value on the pressure gauge. The downward movement of the hydraulic cylinder (i.e. lowering of heavy objects).

The occurrence of.

The foundation production and acceptance of electric elevators for foundation construction should comply with the user manual and regulatory requirements.

Variable cost.Construction electric elevators should be equipped with cable guide frames and comply with regulatory requirements.

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.

Steel wire ropes, pulleys, and counterweight steel wire ropes shall comply with the following regulations: the characteristics of steel wire ropes shall comply with the requirements of General Purpose Steel Wire Ropes GB/T20118; Maintenance, wear, deformation, and corrosion of steel wire ropes

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, 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.

supply.Before operating the construction electric elevator, routine inspections should be carried out according to regulations and inspection records should be filled out.

Before installing the construction electric elevator, the foundation should be inspected and approved before installation.

Emergency manual valve: In case of power failure, it can cause the car to descend to the nearest floor position and open the door

Revitalization.Principle 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 90 degree position until it is closed, and then turn the transmission handwheel to lower the plug and achieve sealing.

Civil engineering advantages: The pit depth of the guide rail type lifting platform is generally around 150-300mm, and the top layer is not affected. It can be customized according to the location and environment.

Protective measures should comply with regulatory requirements.
