when the net height of the building entrance is less than 0m, it is allowed to lower the height of the lower door opening, but in any case, the net height of the lower door opening is not less than 8m. (Article 1 of GB26557-2011)
Le Havre.The usual operation of landing and docking.
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.
.Double layer steel mesh: The diameter of the steel bars is 12mm, with a spacing of 200mm.
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.
Tank oil temperature protection: When the oil temperature in the tank exceeds the standard setting value, 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 drops
Setting requirements: The landing door should be standardized and tooled.
And prevent it from starting normally. There should be no device that allows users to cancel warning signals.

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.
High lifting height using side mounted oil cylinders,Le HavreElectric four-wheel elevator, noise free, easy maintenance, and longer service life.
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,Le HavreElevator electric platform, 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).
Installation materials.Protective measures should comply with regulatory requirements.
Degrees, m/s.
Setting requirements: The layout and installation of all cables and wiring of electric elevators should be able to prevent mechanical damage.
Le Havre.When the landing door is closed the full width of the lifting passage opening should be covered.
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 0.75m; If the rated speed is not greater than 0.7m/s, the safety distance can be 0.40m.
The foundation base or embedded parts should be fully embedded in the concrete foundation plate.
