the installation unit should confirm that the foundation, foundation bearing capacity, embedded parts, and foundation drainage measures of the installed construction electric elevator and auxiliary heavy equipment comply with the requirements of the special construction plan for the installation and dismantling of the construction electric elevator based on the construction electric elevator foundation acceptance form, concealed engineering acceptance form and concrete strength report.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 movementVoorburg ,A lifting platform with specifications ranging in height from meter to meters.It is reported that a fixed electric elevator has good lifting stability and can only be used for fixed operations, making high-altitude operations easierSlatina,Voorburg Madison,Acceptance: Concrete strength grade C, strength testing report.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.Later, when there is a major malfunction of the lifting platform, it should be repaired by professional personnel as soon as possible. After the malfunction occurs, it should not be used again to avoid accidents, which should cover the opening with its full width, and should not open towards the lifting passage.Setting requirements: Construction electric elevators should be equipped with up travel (limit) switches.Construction electric elevators outside the lightning protection rangePursuit of excellence,The safety bulletin board for construction electric elevators should be hung at the protective shed of the electric elevator, with a size of meters by meters.Setting requirements: The quality of the standard section should meet the requirements of the product manual. Before installing the construction electric elevator, all components should be inspected, and standard sections and other components with severe wear and deformation should be replaced.When a rigid mm square or circular flat surface is applied with a normal force of N to either side of the door, the door may not meet the above requirements, but safety should be maintained.

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.Economic management,Voorburg Stavavara,When the wall bracket adopts non matching standard products, design calculations should be carried out.The water cooling of hydraulic stations is generally tubular water cooling. The selection is based on the heat load to calculate the heat exchange area, while the air-cooled electric elevator uses an air cooler to calculate the heat exchange capacity based on the heat load. Then, the selection calculation is carried out under the condition of satisfying the flow rate. So, these two types of cooling are different and have significant differences.Setting requirements: The verticality deviation of the installation of the guide rail frame of the construction electric elevator should comply with the requirements of the user manual and specifications, as specified in the above table.Voorburg ,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.Once again, weekly inspections should be conducted to check whether the connecting screws at various parts of the lifting platform are tightened, whether the sealing rings are damaged or ineffective,Voorburg New Songqi, whether there is a lack of hydraulic oil, and whether the oil cylinder is leaking. It is necessary to clean the lifting frame scissors, wiring and oil cylinder once a week to avoid dust and debris affecting normal operation.Principle of electric elevator rotary valve: When the electric elevator rises, the rotary valve will automatically open. To close the plug valve, and then turn the transmission handwheel to lower the plug and achieve sealing.
