EvlerElectric Drivers of construction electric elevators should hold special construction operations and are not allowed to operate without a certificate.
Small safe operation distance: Circuit voltage (kV) of external power lines<11~1035~110220330~550 Small safe operation distance (m) 4681015 Setting requirements: A small safe distance should be maintained between the outer edge of the construction electric elevator and the edge of the external overhead power line.
Evler.Only after the operation of professional personnel can the suspension cage movement be restored.
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,EvlerMigao Electric Elevator,EvlerElectric bed elevator, and safety features. Please rest assured to use.
.Construction electric elevators outside the lightning protection range
Especially suitable for steel structured factories, suitable for both indoor and outdoor installation.
Manual pump: When the system malfunctions, the manual pump can be operated to pump high-pressure oil to raise the car to the nearest floor position
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 it worked normally.
The detailed reason why water cannot be used to flush the hydraulic station is that doing so will corrode the oil tank in the hydraulic station, and once water is mixed in the hydraulic station, the damage to the hydraulic system is very large. Therefore, it will simply form pipeline corrosion, water vaporization, and other phenomena that can cause adverse effects or results for hydraulic electric elevators. Therefore it is necessary to prevent such actions to ensure the normal operation and service life of the hydraulic station.
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.
analysis.The safety distance between the outer edge of the upper part of the landing door and the moving parts of the electric elevator during normal operation should not be less than 0.75m; If the rated speed is not greater than 0.7m/s, the safety distance can be 0.40m.
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,EvlerSmall 100kg electric elevator, the door should be able to withstand and have no deformation; - Deformation not exceeding 30mm; After the test, it worked normally.
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 list of materials for making landing doors is as follows: Table 1: List of materials for making landing doors. Landing doors should be installed at the entrance of each landing station, and the landing doors should function properly.
Good quality.In addition to ground protective fences, 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, a half height middle crossbar, and a toe board at least 150mm above the ground.
Steel wire rope construction electric elevators and reusable steel wire ropes should be equipped with anti loosening rope devices, which should have compliant loosening rope switches and be able to interrupt any movement of the lifting cage until it is approved by a professional
The motor of the hydraulic guide rail lifting platform is set around the wellbore, occupying a relatively small area, improving the utilization rate of the wellbore area.
Evler.Civil engineering advantages: The pit depth of the guide rail type lifting platform is generally around 150-300mm, and the top layer is not affected. It can be customized according to the location and environment.
Speed limit wire rope switch. When the speed limit wire rope trips or breaks. Make the electric elevator unable to start.
Safety performance: Electric elevators not only have the safety device of traditional traction elevators, but also have an overflow valve to prevent excessive system pressure during upward movement
