MingshanExternThe landing door should meet the requirements of the specifications and achieve standardization.
Setting requirements: The wall bracket should use the manufacturer's matching standard products.
Mingshan.The top of the hanging cage is accessible; d) During installation/disassembly/maintenance/inspection of the device; e) Inside the hanging cage.
Installation verticality deviation guide rail frame erection height, h/mH≤ 7070100150H& gt; 200 verticality deviation/mm≤ (1/100h≤ 70≤ 90≤ 110≤ 130 pairs of steel wire rope construction electric elevators, the verticality deviation of the guide rail frame should not exceed (5/1000) h.
.Setting requirements: Each landing entrance should be equipped with a landing door, which should cover the opening with its full width and should not open towards the lifting passage.
Monthly maintenance and inspection of hydraulic lifting platform rollers, intermediate shafts and bearings, oil cylinder pin shafts and bearings, and at this position, the hydraulic ground should be 40-50 millimeters higher than the bottom of the box. If the hydraulic oil becomes dark, sticky, or has foreign objects such as gravel, it should be replaced in a timely manner (32 # hydraulic oil). Annual maintenance and inspection of all hydraulic pipelines and joints of the lifting platform. The pipeline must not be damaged, and the joints must not be loose. All joints must be tightened. Remove and disassemble the lowering valve of the lifting platform, blow out the plunger with compressed air, then install it and reinstall it. Drain and discard the hydraulic oil, tighten the joint, remove the oil filter, clean it with compressed air, and then return it to the oil tank and connect the pipeline.
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.
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, design,MingshanSmall and simple electric elevator, and production materials should be confirmed by the manufacturer or reviewed by the technical leader of the installation unit, and verified by experts.
Before installing the construction electric elevator, it is driven by the pressure generated by its own weight, greatly saving energy and reducing consumption.
demand.Steel wire ropes, pulleys,MingshanHand propelled electric elevator, 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
Use floor doors and cage door devices on construction sites where conditions permit.
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, and report any problems found to the user unit.
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.
Excellent service.When the wall bracket cannot meet the requirements of the construction site, it should be designed and calculated separately.
And prevent it from starting normally. There should be no device that allows users to cancel warning signals.
The verticality of the guide rail frame should meet the requirements of the specifications.
Mingshan.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, regularly maintain and extend its service life, and create greater benefits for the enterprise. What is the matching degree of electric elevators? Everyone has always been confused. In short, the matching degree of electric elevators is how the height of the electric elevator can be combined with the operating height. Electric elevators are not used frequently, so we must make it clear based on the actual operating height and actual load capacity when using electric elevators. If the frequency is too high,MingshanMobile electric elevator, We suggest considering purchasing a guide rail electric elevator or a scissor fork electric elevator. The scissor fork electric elevator can achieve a maximum load capacity of 100 tons, which effectively solves the problem of load capacity. If the frequency of use is too high and the height is relatively high, we recommend using a guide rail electric elevator. This type of electric elevator is not easy to malfunction under high-frequency operation, By solving the load capacity and frequency of use, the matching problem of electric elevators is effectively solved. Concept of electric elevator rotary valve: The electric elevator rotary valve is a type of valve that quickly opens and closes, and the rotary valve can reduce oil pipeline channels and optimize line settings.
Setting requirements: The layout and installation of all cables and wiring of electric elevators should be able to prevent mechanical damage.
