When the foundation is set on the roof or floor structure, the bearing capacity of its supporting structure should be checked.Safety performance: Electric elevators not only have the safety device of traditional traction elevators, but also have an overflow valve to prevent excessive system pressure during upward movementZwaller,Construction electric elevators must be equipped with lifting cages and reusable buffers and comply with regulatory requirements.The quality of the standard section should comply with the product manual and specification requirements.Mati,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.When the door is closed, except for the gap between the lower part of the door that should not exceed mm, any through-hole and opening size related to the distance between any door and adjacent moving parts, as well as the gap around the door or the gap between parts, etc.During normal operation the horizontal distance between the closed cage door and the closed landing door should not exceed mm. Otherwise,ZwallerGrenoble, measures should be taken to make it meet the requirements,ZwallerCangzhou, or side protection devices at the entrance of the landing station that meet the requirements should be equipped. The distance between any opening between the side protection device and the hanging cage or landing door should not exceed mm.Online consultation,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.Drainage measures need to be considered around the foundation. (Drain the accumulated water on the foundation).Especially suitable for steel structured factories, suitable for both indoor and outdoor installation.

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,ZwallerChengde, the side protection device for the landing entrance should be equipped.Quotation sheet,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 degree position until it is closed, and then turn the transmission handwheel to lower the plug and achieve sealing.If the set screw is loose, be sure to pin it tightly to prevent accidents caused by the shaft pin falling off. Hydraulic oil should be kept clean and replaced every months.The foundation production and acceptance of electric elevators for foundation construction should comply with the user manual and regulatory requirements.Zwaller,The advantages and disadvantages of several commonly used electric lifting mechanisms are as follows: hydraulic electric lifting mechanisms: using hydraulic technology, smooth lifting and low noise.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 degrees;. When the attachment device does not meet the requirements of the 'User Manual' due to conditions, 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.The scissor type electric elevator is a widely used high-altitude operation special equipment. Its scissor mechanical structure ensures high stability of the lifting platform, wide working platform, and high bearing capacity
