Nai meihengEleThe hydraulic oil forms a certain pressure by the vane pump, and enters the lower end of the hydraulic cylinder through an oil filter, 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, 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 safety notice board for construction electric elevators should be prominently placed on the hanging cage for the rated load capacity and rated number of passengers of the construction electric elevator. It is strictly prohibited to use construction electric elevators beyond the rated load capacity or rated number of passengers.
Nai meiheng.Setting requirements: The up travel (limit) switch should be able to automatically stop the cage running at the rated speed before reaching the upper limit switch, but should not trigger the up travel (limit) switch as high
Electric elevators used in various places.
.The landing door should be in a normally closed state. Without the permission of the construction electric elevator driver, the landing door shall not be opened.
The safety notice board for construction electric elevators should be prominently placed on the hanging cage for the rated load capacity and rated number of passengers of the construction electric elevator. It is strictly prohibited to use construction electric elevators beyond the rated load capacity or rated number of passengers.
To ensure safe and reliable braking of the lifting platform and prevent accidents, a hydraulic control one-way valve, also known as a hydraulic lock, is added to ensure safe self-locking in the event of an accidental rupture of the hydraulic pipeline. An overload sound control alarm has been installed to distinguish between overload or equipment failure. Electrical system explosion-proof button SB1&flash; The rotation of the SB6 motor and the commutation of the explosion-proof electromagnetic directional valve are used to maintain load increase or decrease, and; Program adjustment time delay to avoid frequent movement of electric elevators that may affect their service life.
Setting requirements: Each landing entrance should be equipped with a landing door, which should cover the opening with its full width and should not open towards the lifting passage.
The suspension cage movement can only be resumed after operator operation.
From the perspective of the safety performance of the machinery itself,Nai meihengSmall mobile electric elevator,Nai meihengElectric elevator mechanism, those that have undergone national safety certification will not have significant safety issues. The main problem is that after using the electric elevator for a period of time, mechanical components may fall off or be damaged due to various factors. This problem depends on regular inspection and maintenance of the machinery
Promise and keep promise.When a rigid 5000mm2 square or circular flat surface is applied with a normal force of 600N to either side of the door, the door may not meet the above requirements, but safety should be maintained.
The entrance of each landing platform must be equipped with a landing door, which must open towards the landing platform side, and the door bolt must be set on the side next to the construction electric elevator.
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.
Setting requirements: The landing door should be standardized and tooled.
Inspection standard.Before operating the construction electric elevator, routine inspections should be carried out according to regulations and inspection records should be filled out.
Greater than 0.04s; When the hydraulic buffer is used, and the action of the hydraulic buffer shall be monitored by the Electrical safety switch. When the hydraulic buffer is compressed, the cage shall not
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
Nai meiheng.Setting requirements: Before starting work every day and changing shifts, the driver of the construction electric elevator should inspect the construction electric elevator according to the requirements of the user manual and specifications, record the inspection results, and report any problems found to the user unit.
Setting requirements: The wall bracket should use the manufacturer's matching standard products.
The wall bracket of the construction electric elevator should be intact and reliably fixed, and its attachment distance, wall bracket spacing, and end height must comply with the requirements of the 'User Manual'. The angle between the plane of the wall bracket and the normal direction of the attachment surface should not exceed 8 degrees;. When the attachment device does not meet the requirements of the 'User Manual' due to conditions,Nai meihengElectric pull rod elevator, its calculation sheet, design, and production materials should be confirmed by the manufacturer or reviewed by the technical leader of the installation unit, and verified by experts.
