XiqingElectricSetting requirements: The layout and installation of all cables and wiring of electric elevators should be able to prevent mechanical damage.
The setting of the cable guide frame should comply with the user manual and regulatory requirements.
Xiqing.How to determine the sufficient amount of clean oil for the hydraulic station of an electric elevator? Why cannot water be used to flush the hydraulic station of an electric elevator?
Setting requirements: For construction electric elevators with foundations installed on roof slabs, floors, or other lower suspended structures, the bearing capacity of the foundation support structure should be checked. Click here to download the construction technical information for free. Basic drainage facilities should be installed.
.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, low level doors can be used. Low level doors should meet the following requirements: the height of the door should be between 1m and 2m. And there should be at least protective railings it worked normally.
In addition to ground protective fences, a half height middle crossbar, and a toe board at least 150mm above the ground.
Steel wire ropes, pulleys, and counterweight steel wire ropes shall comply with the following regulations: the characteristics of steel wire ropes shall comply with the requirements of General Purpose Steel Wire Ropes GB/T20118; Maintenance, deformation, and corrosion of steel wire ropes
Horizontal lead screw mechanical electricity
Construction electric elevators should be equipped with lower limit switches that are sensitive and reliable.
The wall bracket of the construction electric elevator should be intact and reliably fixed, and its attachment distance, wall bracket spacing, and end height must comply with the requirements of the 'User Manual'. The angle between the plane of the wall bracket and the normal direction of the attachment surface should not exceed 8 degrees;. When the attachment device does not meet the requirements of the 'User Manual' due to conditions, its calculation sheet, and production materials should be confirmed by the manufacturer or reviewed by the technical leader of the installation unit and verified by experts.
Meticulous workmanship.The distance between the electric hoist and overhead line in Electrical safety construction shall meet the specification requirements,XiqingElectric elevator battery, otherwise protective measures shall be taken.
During loading and unloading, the horizontal distance between the edge of the cage door and the edge of the landing station should not exceed 50mm.
The scaffolding of the parking platform should be laid tightly and firmly.
Before installation,XiqingElectric lifting platform 2 meters, the installation unit should confirm that the foundation, foundation bearing capacity, embedded parts, and foundation drainage measures of the installed construction electric elevator and auxiliary heavy equipment comply with the requirements of the special construction plan for the installation and dismantling of the construction electric elevator based on the construction electric elevator foundation acceptance form, concealed engineering acceptance form, and concrete strength report.
How much is it.The quality of the standard section should comply with the product manual and specification requirements.
When a suspension cage with a rated load capacity acts on the buffer at a speed greater than the rated speed of 0.2m/s, the average deceleration of the suspension cage should not exceed 1g, and the time when the peak deceleration exceeds 5g should not exceed
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, rather than in the shaft; A buffer should be installed that can absorb the energy of the moving mechanism and reduce impact.
Xiqing.Steel wire ropes, pulleys, and counterweight steel wire ropes shall comply with the following regulations: the characteristics of steel wire ropes shall comply with the requirements of General Purpose Steel Wire Ropes GB/T20118; Maintenance, wear, deformation, and corrosion of steel wire ropes
Before installation,XiqingSmall and simple electric elevator, the installation unit should confirm that the foundation, foundation bearing capacity, embedded parts, and foundation drainage measures of the installed construction electric elevator and auxiliary heavy equipment comply with the requirements of the special construction plan for the installation and dismantling of the construction electric elevator based on the construction electric elevator foundation acceptance form, concealed engineering acceptance form, and concrete strength report.
Mechanical devices controlled by cage movement should not be used to open or close the landing door.
