When applying a normal force of N to any position on either side of the door using a rigid mm square or circular flat surface in the locked position of the landing door, it worked normally.Construction electric elevators should be equipped with cable guide frames and comply with regulatory requirements.Mentougou,After the limit switch is activated, only professional personnel can restore the movement of the suspension cage.Setting requirements: The foundation and foundation of the construction electric elevator should meet the requirements of the user manual. Before installing the construction electric elevator, the foundation should be inspected and accepted according to the requirements of the specifications. Only after passing the inspection can the installation be carried out.Kankaanpaa,The full height landing door should meet the following requirements: the net height of the landing door opening should not be less than m. In special circumstances,MentougouSt. Louis , when the net height of the building entrance is less than m, 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 m. (Article of GB-)When the landing door is closed, the full width of the lifting passage opening should be covered.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

News Abstract: The development of the lifting platform industry will continue to grow in recent years! With the continuous development of electric lifting machinery for high-altitude operations in recent years, the products of electric lifting platform vehicles have been continuously improved, and various new technologies and materials have emerged, making the further development of lifting platform vehicles possible.Setting requirements: Construction electric elevators should be equipped with a down travel (limit) switch. The down travel (limit) switch should be able to automatically stop the cage running at rated speed before reaching the lower limit switch.In order to meet the needs of contemporary audiences and achieve perfect effects, stage machinery is particularly important on the stage. On the stage, there are suspension rods, suspension points, lighting bridges,MentougouZdunskavora, lighting suspension cages, and fire curtains. Under the stage there are lifting platforms, car platforms, turntables, and lifting orchestras. Some lifting platforms are equipped with turntables, or there are lifting platforms in the turntables. Various types of lifting platforms are equipped in professional opera houses, dance theaters, drama theaters, and many internationally renowned music halls. It has the functions of quickly changing scenery, meeting the needs of stage craft layout, meeting the needs of stage design and choreographers, creating special atmosphere and effects, and changing the stage form according to the needs of the performance.Where is good,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, the hydraulic ground should be - millimeters higher than the bottom of the box. If the hydraulic oil becomes dark, sticky, or has foreign objects such as gravel, 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.Emergency manual valve: In case of power failure it can cause the car to descend to the nearest floor position and open the doorSetting requirements: The installation and dismantling workers, electricians, and other operators of construction electric elevators should have special construction operations.

The angle between the wall bracket and the horizontal plane should comply with the requirements of the user manual.Job description,To meet the needs of choreographers and choreographers in different plays, different heights of the lifting platform can be used to change the shape of the stage according to the requirements of the choreographers and choreographers,MentougouTaocheng, and save manpower and material resources for setting up. By using the tilting device of the lifting platform to form a tilted platform, a better highlighting effect can be achieved in various performances. According to the needs of the plot, special atmosphere and effects can be created. Even simple stage machinery often participates in performance activities, creating unexpected atmosphere and effects according to the needs of the plot. For example, using the low-speed descent of the lifting platform to represent a sunken ship in the sea, using the valves on the lifting platform and the sudden disappearance and appearance of actors on the lifting platform.Degrees, it can cause the car to descend to the nearest floor position and open the doorMentougou,When the landing door is closed, the full width of the lifting passage opening should be covered.Electric elevators used in various places.Every theater is a public place with a large number of people, and safety considerations should be taken into account in stage design. According to relevant national regulations, in order to prevent accidents caused by the crushing of electric elevators or improper control by drivers. Electric elevators should be equipped with the following necessary safety devices to ensure that the car of the electric elevator stops rising or falling in a timely manner.
