Le MansDunkirkAnalysis and research on the causes of cracks

The use of standard section connecting bolts should comply with the user manual and specification requirements.During the use period, the user unit should organize professional technical personnel to inspect the construction electric elevator monthly according to the standard requirements,Le MansAndrea, and record the inspection results.Le Mans, with a spacing of mm.Messina,Before installation, the installation unit should confirm that the foundation foundation bearing capacity, embedded parts,Le MansBazhou, concealed engineering acceptance form, and concrete strength report.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.Setting requirements: The guide rail should be rigid and flexible components such as wire ropes or chains should not be used.

After the electric elevator passes the inspection, the user unit shall organize the leasing unit, installation unit, and supervision unit to conduct acceptance. For the implementation of construction general contracting, the acceptance shall be organized by the construction general contracting unit. The acceptance form should be signed by the relevant responsible person.PoleDrainage measures need to be considered around the foundation. (Drain the accumulated water on the foundation).Inspection requirements,It is reported that a fixed electric elevator has good lifting stability and can only be used for fixed operations, making high-altitude operations easierBefore operating the construction electric elevator, routine inspections should be carried out according to regulations and inspection records should be filled out.Emergency manual valve: In case of power failure, it can cause the car to descend to the nearest floor position and open the door

Flat screw mechanical electric lifting mechanism: The lifting platform of this structure has the advantages of small civil engineering coordination, shallow foundation pit required, 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.average method,Braking. The brake limit switch for partial motion control of the electric hoist traction machine. Assembly that restricts the operation of the lift car when it is opened to a high or low position; If the limit switch controls the overtravel switch. When the car travels to a high or low position, it will take on the function of raising or lowering. In order to prevent the lift car from crashing or sinking, stage equipment should be dismantled with over travel switches that can cut off power and cannot be automatically reset, and installed in the machine room, rather than in the shaft; A buffer should be installed that can absorb the energy of the moving mechanism and reduce impact.Before installing the construction electric elevator, the foundation should be inspected and approved before installation.The landing door should be in a normally closed state. Without the permission of the construction electric elevator driver,Le MansAtlanta, the landing door shall not be opened.Le Mans,Setting requirements: The guide rail should be rigid and flexible components such as wire ropes or chains should not be used.According to the needs of different performance genres, using an orchestra pit lift can combine a framed stage with a large lip or even an extended stage. In an experimental theater, using a lift can make the theater have various forms such as an end stage, an extended stage, an island stage, an intermediate stage, a T-shaped stage, or a hall.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.
