Emergency manual valve: In case of power failure, it can cause the car to descend to the nearest floor position and open the door
Setting requirements: The spacing of wall brackets along the vertical direction should comply with the provisions of the user manual.
Verona.The coaxiality between the motor shaft and the worm shaft in the aluminum alloy electric elevator drive device should be less than 0.1mm, and there should be a 2mm gap at the shaft end to ensure that the motor bearings bear reasonable loads and reduce motor operating noise; electric
When applying a normal force of 300N to any position on either side of the door using a rigid 5000mm2 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 30mm; After the test, it worked normally.
.The use of standard section connecting bolts should comply with the user manual and specification requirements.
The bearing capacity of the ground under the concrete foundation plate should be greater than 0.15Mpa.
The safety distance between the outer edge of the upper part of the landing door and the moving parts of the electric elevator during normal operation should not be less than 0.75m; If the rated speed is not greater than 0.7m/s, the safety distance can be 0.40m.
Setting requirements: Before starting work every day and changing shifts, the driver of the construction electric elevator should inspect the construction electric elevator according to the requirements of the user manual and specifications, record the inspection results,VeronaElectric elevator mechanism, and report any problems found to the user unit.
Setting requirements: Steel wire rope electric elevators and reusable steel wire ropes should be equipped with anti loosening rope devices, which should have compliant loosening rope switches and be able to interrupt any movement of the cage until it passes through the
The counterweight guide rail should meet the specification requirements.
Price.Horizontal lead screw mechanical electricity
As a material loading and unloading equipment recognized by customers in the lifting platform, the guide rail hydraulic lifting platform is superior in terms of product, civil engineering, can achieve multiple points, and can be controlled up and down floors to achieve safe use.
When the horizontal distance between the edge of the cage and the edge of the landing or between the cage and the landing door is greater than 150mm and there is no effective protection from other structures, the side protection device for the landing entrance should be equipped.
Safety grounding device. In order to protect against electrical equipment. The metal casing of electrical equipment and the metal structure of electric elevators should be equipped with a safety grounding device. The grounding wire should operate multiple wires, and the neutral wire should not be arbitrarily held as a safety grounding wire. Its grounding resistance should not exceed 4 ohms; The power supply of the electric elevator can be cut off.
total cost.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, it can be stopped arbitrarily within the range of travel.
Construction electric elevators should be equipped with upper limit switches that are sensitive and reliable.
Model Example: Hanging Cage Specification: LABSC200/200TD3200x1500 Type I: 2900~3600 Type II: 2900~3600 Type V: 1800~250044003800 Technical Requirements: The load-bearing capacity of the foundation should be greater than P: P=(hanging cage weight+outer cage weight+total weight of guide rail frame+counterweight+load) x0.02 (kN).
Verona.From the above comparison, it can be seen that hydraulic electric lifting mechanisms have stable lifting, low noise, long service life, large load bearing capacity, and are relatively simple, making them suitable for use in stage equipment.
Buffer. In order to increase the energy for the car to hit the top or sink to the bottom. Remove rubber or sponge from the buffer and cabin to increase their impact energy; Rope groove slipping and other accidents caused the car to suddenly fall, resulting in a safety clamp. To prevent breakage of the lifting wire rope. A safety clamp that can simultaneously cut off the power supply and stop the car from falling should be removed from the car. A car without safety tongs is not allowed to ride or carry people. If it is a simple electric elevator, there should be a safety device (such as a safety stop pin) to prevent people from suddenly falling when loading and unloading goods in the car; Electric elevators with three or more floors (including three floors) for passengers or passengers.
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,VeronaSmall mobile electric elevator, 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,VeronaPure electric curved arm elevator, 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.
