YunchengElectrSetting requirements: The layout and installation of all cables and wiring of electric elevators should be able to prevent mechanical damage.
Setting requirements: The landing door should be standardized and tooled.
Yuncheng.The downward movement of the hydraulic cylinder (i.e. heavy object lowering). 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 passes through the balance valve, hydraulic control one-way valve, energy-saving valve and explosion-proof electric valve
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.
.Use floor doors and cage door devices on construction sites where conditions permit.
The wall bracket of the construction electric elevator should be intact and reliably fixed,YunchengElectric mobile elevator, 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, its calculation sheet, design,YunchengLight electric elevator, and production materials should be confirmed by the manufacturer or reviewed by the technical leader of the installation unit, and verified by experts.
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.
It is reported that a fixed electric elevator has good lifting stability and can only be used for fixed operations, making high-altitude operations easier
The magnetic directional valve returns to the fuel tank. To ensure stable landing 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 landing speed does not change due to heavy objects. It is adjusted by the saving valve
The hydraulic oil forms a certain pressure by the vane pump, and enters the lower end of the hydraulic cylinder through an oil filter, explosion-proof electromagnetic directional valve, throttle valve, hydraulic control one-way 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).
Discount.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.
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 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.
Protective measures should comply with regulatory requirements.
Speed limit wire rope switch. When the speed limit wire rope trips or breaks. Make the electric elevator unable to start.
Honesty is the foundation.Implementing multiple shifts of homework should fill in and submit records according to regulations.
When a single steel wire rope is excessively stretched, the Electrical safety device shall stop the operation of the electric lift.
Construction electric elevators outside the lightning protection range
Yuncheng.Pipeline rupture valve: When the hydraulic system pipeline ruptures and the car stalls and descends, the full width of the lifting passage opening should be covered.
The setting of the cable guide frame should comply with the user manual and regulatory requirements.
