Flat screw mechanical electric lifting mechanism: The lifting platform of this structure has the advantages of small civil engineering coordination， large stroke， stable operation， low noise， 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 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.
Tissau yverosInstallation position of upper limit switch: Under normal working conditions， the distance between the upper limit switch and the upper limit switch is .m for SC type construction electric elevators， and .m for SS type construction electric elevators (person)
Advantages of electric elevator rotary valve: Simplify the installation of electric elevator pipelines; The operation is more convenient，Tissau yverosAvery on the Seine River， 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.
YamagataSpiral electric lifting mechanism: With all the functions of a regular lifting platform，Tissau yverosFerrara， the main feature is that the equipment occupies a small foundation pit and has a large stroke. The equipment has a height of only -mm and a travel distance of up to m. It is particularly suitable for buildings with stages built on two or more floors due to space constraints.
Construction electric elevators outside the lightning protection range
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 movement
Before operating the construction electric elevator， routine inspections should be carried out according to regulations and inspection records should be filled out.
The inner bearing of the roller in the device is in good condition， and a complete grease film surface is maintained between the curved surface of the roller and the main chord of the aluminum alloy electric elevator. A good grease film surface can reduce wear and noise
As a material loading and unloading equipment recognized by customers in the lifting platform， civil engineering， and operating costs. The editor of the electric elevator will provide a detailed analysis: the advantages of the product are that the equipment bears a large load， can achieve multiple points， and can be controlled up and down floors to achieve safe use.
Where is goodThe connection method and angle between the wall bracket and the building structure should comply with the requirements of the user manual.
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
Setting requirements: Drainage measures should be set up for the foundation of construction electric elevators to ensure smooth drainage.
Monthly maintenance and inspection of hydraulic lifting platform rollers， intermediate shafts and bearings， oil cylinder pin shafts and bearings， boom hinge shafts and bearings for wear. Add some oil to each part to extend the service life of the lifting platform bearings. The quality and level of hydraulic oil. The lifting platform should be raised throughout the entire process， and at this position， or has foreign objects such as gravel sticky， it should be replaced in a timely manner ( # hydraulic oil). Annual maintenance and inspection of all hydraulic pipelines and joints of the lifting platform. The pipeline must not be damaged and the joints must not be loose. All joints must be tightened. Remove and disassemble the lowering valve of the lifting platform， blow out the plunger with compressed air， then install it and reinstall it. Drain and discard the hydraulic oil， tighten the joint， remove the oil filter， clean it with compressed air， and then return it to the oil tank and connect the pipeline.
marketPipeline rupture valve: When the hydraulic system pipeline ruptures and the car stalls and descends， it can automatically cut off the oil circuit and stop descent
The device should be used within the valid calibration period and operate effectively and reliably. The anti fall safety device should have a valid inspection certificate (or inspection report)， and the validity period should not exceed year. Anti fall safety devices have been manufactured for five years
Setting requirements: The landing door should be standardized and tooled.
Tissau yverosThe entrance of each landing platform must be equipped with a landing door， which must open towards the landing platform side，Tissau yverosPesack， and the door bolt must be set on the side next to the construction electric elevator.
In addition to ground protective fences， low level doors can be used. Low level doors should meet the following requirements: the height of the door should be between m and m. And there should be at least protective railings a half height middle crossbar， and a toe board at least mm above the ground.
The bearing capacity of the building structure at the attachment point of the wall bracket should meet the requirements specified in the user manual for construction electric elevators.
