Principle of electric elevator rotary valve: When the electric elevator rises, the rotary valve will automatically open. To close the plug valve, it is necessary to first turn the handle to turn the plug to a 90 degree position until it is closed, the bracket should be supported to prevent the electric elevator from overturning. Electrical and hydraulic systems should be maintained by professional personnel; When the battery level display is less than 40%
Protective measures should comply with regulatory requirements.
.Secondly, for the replacement of hydraulic oil on the lifting platform, it is recommended to replace it every three months. If the frequency of use is not high, it can be replaced once a year. The hydraulic oil must be clean, and after changing the hydraulic oil, it must be automatically lifted and lowered 2 to 3 times to ensure that the air in the oil cylinder is completely discharged, maintain sufficient space, and ensure that the lifting platform can be lifted to the rated lifting height.
Steel wire ropes, 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
It is understood that the scissor type lifting platform is a widely used specialized equipment for high-altitude operations. Its shear fork mechanical structure provides high stability for the lifting platform, wide working platform, and high load-bearing capacity, making the range of high-altitude operations larger and suitable for multiple people working simultaneously. The lifting power is divided into 24V, 220V or 380V power supplies, diesel engines, using Italian and domestic hydraulic pump stations, and the table top is equipped with anti slip insulation buckle plates, which have anti slip,Gansu10 meter electric lifting platform, insulation, and safety features. Please rest assured to use.
Construction electric elevators should be equipped with cable guide frames and comply with regulatory requirements.
When adding hydraulic oil, we can extend the oil cylinder to the high position for filling. When filling, the lifting platform should not exceed the high position, and then retract the oil cylinder back to the low position to check if the hydraulic oil level is lower than the low position, and maintain it between the two.
The distance between the electric hoist and overhead line in Electrical safety construction shall meet the specification requirements, otherwise protective measures shall be taken.
Create brilliance.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 net height of the landing door opening should not be less than 8m,Gansu200 kg electric elevator, and the difference between the net width and the outlet width of the cage door should not exceed 120mm. When the floor door is closed,GansuElectric hydraulic elevator platform, except for the gap between the lower part of the door that should not exceed 35mm, 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 4 of 'Mechanical Safety - Safety Distance to Prevent Upper and Lower Limbs from Touching Dangerous Areas' GB23821-2009.
Pipeline rupture valve: When the hydraulic system pipeline ruptures and the car stalls and descends, it can automatically cut off the oil circuit and stop descent
When the wall bracket cannot meet the requirements of the construction site, it should be designed and calculated separately.
how.The advantages and disadvantages of several commonly used electric lifting mechanisms are as follows: hydraulic electric lifting mechanisms: using hydraulic technology, smooth lifting and low noise.
Safety devices: Electric elevators for construction should be equipped with overload detection devices. When the load inside the cage exceeds 10% of the rated load capacity the overload detection device will give a warning signal inside the cage,
When the wall bracket cannot meet the requirements of the construction site, 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.
Construction electric elevators should be equipped with cable guide frames and comply with regulatory requirements.
The verticality of the guide rail frame should meet the requirements of the specifications.
