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 positionWhen the wall bracket adopts non matching standard products, design calculations should be carried out.Fot,Mechanical devices controlled by cage movement should not be used to open or close the landing door.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, and ensure that the lifting platform can be lifted to the rated lifting height.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 m and m. And there should be at least protective railings, a half height middle crossbar,FotElectric barrier free elevator, and a toe board at least mm above the ground.

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 mm and there is no effective protection from other structures, the side protection device for the landing entrance should be equipped.The stopper bearing of the mechanism is kept intact.The safety distance between the outer edge of the upper part of the landing door and the moving parts of the electric elevator during normal operation should not be less than .m; If the rated speed is not greater than .m/s, the safety distance can be .m.Installation requirements,It is reported that a fixed electric elevator has good lifting stability and can only be used for fixed operations making high-altitude operations easierPrinciple 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.Setting requirements: For construction electric elevators with foundations installed on roof slabs, floors, or other lower suspended structures, the bearing capacity of the foundation support structure should be checked. Click here to download the construction technical information for free. Basic drainage facilities should be installed.

Tank oil temperature protection: When the oil temperature in the tank exceeds the standard setting value,Fot2 ton electric elevator, 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 dropsInspection items,Emergency manual valve: In case of power failure, it can cause the car to descend to the nearest floor position and open the doorGreater than .s; When the hydraulic buffer is used, the oil level shall be checked, and the action of the hydraulic buffer shall be monitored by the Electrical safety switch. When the hydraulic buffer is compressed the cage shall notFlat screw mechanical electric lifting mechanism: The lifting platform of this structure has the advantages of small civil engineering coordination, large stroke shallow foundation pit required, stable operation,FotElectric lifting platform 2 meters, 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.Fot,Flat screw mechanical electric lifting mechanism: The lifting platform of this structure has the advantages of small civil engineering coordination, 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.Setting requirements: The installation and dismantling workers, electricians, and other operators of construction electric elevators should have special construction operations.Chain type electric lifting mechanism: With a good guiding mechanism, it can ensure that the equipment does not tilt during operation. Gear and rack electric lifting mechanism: precise transmission and high cost.
