otherwise protective measures shall be taken.Safety performance: Electric elevators not only have the safety device of traditional traction elevators

The distance between the electric hoist and overhead line in Electrical safety construction shall meet the specification requirements, but also have an overflow valve to prevent excessive system pressure during upward movementlubbock ,The usual operation of landing and docking. The installation position of the upper limit switch should comply with the following: when the lifting speed is less than .m/s, the upper safety distance L left after the upper limit switch is triggered by the hanging cage should not be less thanEvery 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.Guinea-Bissau,lubbock Mobile electric hydraulic elevator,Pipeline rupture valve: When the hydraulic system pipeline ruptures and the car stalls and descends, it can automatically cut off the oil circuit and stop descentThe foundation base or embedded parts should be fully embedded in the concrete foundation plate.Setting requirements: The layout and installation of all cables and wiring of electric elevators should be able to prevent mechanical damage.

In order to meet the needs of contemporary audiences and achieve perfect effects, in addition to lighting and sound, stage machinery is particularly important on the stage. On the stage there are suspension rods, suspension points, lighting bridges, 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,lubbock 3 meter high electric elevator, dance theaters, drama theaters, and many internationally renowned music halls. It has the functions of quickly changing scenery,lubbock 6 meter high electric elevator, 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.The safety overtravel of limit switches and upper limit switches should comply with regulatory requirements.From the perspective of the safety performance of the machinery itself, those that have undergone national safety certification will not have significant safety issues. The main problem is that after using the electric elevator for a period of time,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, 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-)Acceptance: Concrete strength grade C, strength testing report.The setting of the cable guide frame should comply with the user manual and regulatory requirements.

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, the door should be able to withstand and have no deformation; - Deformation not exceeding mm; After the test, it worked normally.Quality assurance,Use floor doors and cage door devices on construction sites where conditions permit.Construction electric elevators should be equipped with lower limit switches that are sensitive and reliable.When the distance between the outer edge of the construction electric elevator and the edge line of the external overhead power line cannot meet the requirements in the table above, effective protective measures should be taken.lubbock ,It is understood that the scissor type lifting platform is a widely used specialized equipment for high-altitude operations. Its shear fork mechanical structure provides high stability for the lifting platform, and high load-bearing capacity, making the range of high-altitude operations larger and suitable for multiple people working simultaneously. The lifting power is divided into V, V or V power supplies, diesel engines, using Italian and domestic hydraulic pump stations, and the table top is equipped with anti slip insulation buckle plates, which have anti slip, insulation, the number of high-rise buildings in urban areas has sharply increased, and the height of buildings has also continued to grow. This has created a demand for high-altitude lifting platform vehicles. Therefore, in order to meet the needs of the domestic market and the public, efforts will inevitably be made to design and produce high-altitude lifting platform vehicles.
