Advantages of electric elevator rotary valve: Simplify the installation of electric elevator pipelines; The operation is more convenient， and the valve can be opened and closed at any time; The installation of a rotary valve reduces the friction of the sealing components; Compact structure， small size， and space saving; Increased the service life of electric elevator pipelines and solved the problem of easy oil leakage.
For customers to use and operate the lifting platform for a long time， the editor briefly introduces how to maintain and repair the lifting platform: First of all， normal maintenance is mainly focused on prevention， especially if any damage or malfunction is detected and corrected or repaired in a timely manner. Careful inspection and maintenance at this time can save costs and avoid larger problems， resulting in costly repairs.
ManhattanCheck the starter potential when the lifting table is not raised or the voltage is too low when the motor load is working. Voltage hydraulic range allowed&
The landing door should meet the requirements of the specifications and achieve standardization.
KennierThen， the lifting platform platform platform that carries the load needs to be balanced， and no deviation of one side is allowed. The lifting of goods does not allow people to stand on both sides of the platform， and the lifting of goods should try to maintain a stable and uniform speed.
Flat screw mechanical electric lifting mechanism: The lifting platform of this structure has the advantages of small civil engineering coordination， shallow foundation pit required， low noise stable operation， accurate positioning， and low cost. Adopting a horizontal screw drive and a scissor fork structure to achieve the lifting motion of the table， it can be stopped arbitrarily within the range of travel.
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.
Stage equipment safety door. To prevent personnel from extending their heads， and feet out of the shaft and objects from falling into the vertical shaft. Its vertical position should be closed， its cabin should be full of doors，ManhattanRome， and the height of the hoistway (hall door) should not be less than meters; The electric door opening and closing switches should be removed from the vertical and passenger compartment doors. In order to prevent accidents caused by vertical， passenger car doors and car roof doors not being closed.; Door interlocks should be installed on both the vertical and passenger compartment doors.
There is a certain itinerary.
Double layer steel mesh: The diameter of the steel bars is mm， with a spacing of mm.
Inspection standardWhen the landing door is closed，ManhattanOrlando， the full width of the lifting passage opening should be covered.
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， it can ensure that the equipment does not tilt during operation. Gear and rack electric lifting mechanism: precise transmission and high cost.
howAcceptance: Concrete strength grade C， strength testing report.
Safety devices: Electric elevators for construction should be equipped with overload detection devices. When the load inside the cage exceeds % of the rated load capacity the overload detection device will give a warning signal inside the cage，
Secondly， the lifting platform is driven by electrical energy and lifted by the hydraulic system. During operation， it is necessary to avoid irregular operations. To ensure the normal and orderly operation of the lifting platform and achieve the ideal unloading level， timely inspection of various functions is essential.
ManhattanSafety 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 movement
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， making the high-altitude operation range wider and suitable for multiple people to work simultaneously. It makes high-altitude operation more efficient and safer
Vertical lead screw electric lifting mechanism: Adopting a lead screw transmission method， it can achieve the lifting of a double-layer tabletop. Multiple lifting platforms can be formed as needed， and different steps can be formed within the travel range to meet the needs of meetings and performances; Pavilion， Terrace， Tower， Pavilion; Ideal props.
