TaiyuanSecond Secondly, the lifting platform is driven by electrical energy and lifted by the hydraulic system. During operation, it is necessary to avoid irregular operations. To ensure the normal and orderly operation of the lifting platform and achieve the ideal unloading level,TaiyuanNew electric elevator, timely inspection of various functions is essential.
When the wall bracket adopts non matching standard products, design calculations should be carried out.
Taiyuan.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,TaiyuanFloor electric elevator, water vaporization it will simply form pipeline corrosion, 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.
Construction electric elevators should be equipped with cable guide frames and comply with regulatory requirements.
.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
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, the side protection device for the landing entrance should be equipped.
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.
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
Construction electric elevators should be equipped with lower limit switches that are sensitive and reliable.
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.
How much does it cost?.Implementing multiple shifts of homework should fill in and submit records according to regulations.
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.
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, the side protection device for the landing entrance should be equipped.
Setting requirements: The foundation and foundation of the construction electric elevator should meet the requirements of the user manual. Before installing the construction electric elevator, the foundation should be inspected and accepted according to the requirements of the specifications. Only after passing the inspection can the installation be carried out.
index.Use floor doors and cage door devices on construction sites where conditions permit.
The upward movement of the hydraulic cylinder involves lifting heavy objects, and the return oil from the upper end of the hydraulic cylinder returns to the oil tank through the explosion-proof electromagnetic directional valve. The additional pressure relief valve is used for adjustment, and the pressure gauge reads the value when observing the pressure gauge
The full height landing door should meet the following requirements: the net height of the landing door opening should not be less than 0m. In special circumstances when the net height of the building entrance is less than 0m, it is allowed to lower the height of the lower door opening, but in any case, the net height of the lower door opening is not less than 8m. (Article 1 of GB26557-2011)
Taiyuan.Setting requirements: The layout and installation of all cables and wiring of electric elevators should be able to prevent mechanical damage.
The use of standard section connecting bolts should comply with the user manual and specification requirements.
Drivers of construction electric elevators should hold special construction operations and are not allowed to operate without a certificate.
