The counterweight guide rail should meet the specification requirements.Flat screw mechanical electric lifting mechanism: The lifting platform of this structure has the advantages of small civil engineering coordination, large stroke,CarlosaStabia Castle, 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.Carlosa,Safety devices: Electric elevators for construction should be equipped with overload detection devices. When the load inside the cage exceeds % of the rated load capacity, the overload detection device will give a warning signal inside the cage,The L distance depends on the selected wall mount model.Bilgorod,CarlosaEnshad,Spiral electric lifting mechanism: With all the functions of a regular lifting platform, 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.There is no need to set up a computer room above the shaft like an elevator, and the top floor height can be installed at least . meters.The bearing capacity of the ground under the concrete foundation plate should be greater than .Mpa.

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.m； When the lifting speed is greater than .m/s, after the upper limit switch is triggered by the hanging cage,CarlosaHejin, the upper small safety distance L should meet the following requirements: L=+.V where L is the upper safety distance; V: Increase speedWhen the wall bracket cannot meet the requirements of the construction site, it should be designed and calculated separately.Information recommendation,Setting requirements: The main connection methods between the wall bracket and the building include: connecting the wall bracket with the embedded parts on the wall; Fix with wall bolts; Embedded bolts; Welding with steel structures.Speed limiter. To prevent the driving speed from exceeding the normal speed. A speedometer should be installed (not required for floors below or including the second floor), which is an individual mechanism that is integrated with a safety clamp; The entrance and exit of the passenger compartment should be equipped with safety doors. Public places, family dormitories, andThe scaffolding of the parking platform should be laid tightly and firmly.

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.Supply chain quality management,Use floor doors and cage door devices on construction sites where conditions permit.The shutdown device (emergency stop switch) should be non automatic reset type.The net height of the landing door opening should not be less than m, and the difference between the net width and the outlet width of the cage door should not exceed mm. When the floor door is closed, except for the gap between the lower part of the door that should not exceed mm, the size of any through-hole and opening related to the distance between any door and adjacent moving parts, as well as the gap around the door or between parts, should comply with the provisions of Table of 'Mechanical Safety - Safety Distance to Prevent Upper and Lower Limbs from Touching Dangerous Areas' GB-.CarlosaSpeed limiter. To prevent the driving speed from exceeding the normal speed. A speedometer should be installed (not required for floors below or including the second floor), family dormitories, andThe distance between the electric hoist and overhead line in Electrical safety construction shall meet the specification requirements, otherwise protective measures shall be taken.Setting requirements: For construction electric elevators that operate in multiple shifts, the handover system should be implemented, and drivers should fill out the handover record form according to the standard requirements. The driver should conduct a pre shift inspection and confirm that there are no errors before starting the machine for operation.
