Li ShiLadder type electric elevatorThe industry needs to be based on technical talents

The landing door should meet the requirements of the specifications and achieve standardization.

The safety notice board for construction electric elevators should be prominently placed on the hanging cage for the rated load capacity and rated number of passengers of the construction electric elevator. It is strictly prohibited to use construction electric elevators beyond the rated load capacity or rated number of passengers.

Li Shi.The installation position of the lower limit switch. The installation position of the lower limit switch should ensure that the contact plate triggers the switch when the rated load of the suspension cage decreases, causing the suspension cage to stop. At this time, the contact plate should also be close to the triggering of the lower limit switch

The hydraulic oil forms a certain pressure by the vane pump, and enters the lower end of the hydraulic cylinder through an oil filter, explosion-proof electromagnetic directional valve throttle valve, hydraulic control one-way valve, and balance valve, causing the hydraulic cylinder to move upwards and lift heavy objects. The return oil at the upper end of the hydraulic cylinder returns to the oil tank through the explosion-proof electromagnetic directional valve, and its rated pressure overflow valve is adjusted. The pressure gauge observes the reading value on the pressure gauge. The downward movement of the hydraulic cylinder (i.e. lowering of heavy objects).

.After the electric elevator passes the inspection,Li ShiElectric hydraulic elevator 15 meters, 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.

To meet the needs of choreographers and choreographers in different plays, different heights of the lifting platform can be used to change the shape of the stage according to the requirements of the choreographers and choreographers, in order to adapt to the requirements of the plot for the scenery or venue, and save manpower and material resources for setting up. By using the tilting device of the lifting platform to form a tilted platform, a better highlighting effect can be achieved in various performances. According to the needs of the plot special atmosphere and effects can be created. Even simple stage machinery often participates in performance activities, creating unexpected atmosphere and effects according to the needs of the plot. For example,Li Shi500kg electric elevator, using the low-speed descent of the lifting platform to represent a sunken ship in the sea, using the valves on the lifting platform and the sudden disappearance and appearance of actors on the lifting platform.

The counterweight guide rail should meet the specification requirements.

Protective measures should comply with regulatory requirements.

Folding arm electric elevators are mostly driven by hydraulic means, and the source of power for the hydraulic system is hydraulic oil. Only when the hydraulic oil quantity is sufficient and the oil quality is high, can the folding arm electric elevator provide greater torque output, thereby improving work efficiency. So, how can we determine whether the newly added hydraulic oil quantity is sufficient? What is the hydraulic oil quantity standard?

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,Li ShiMicro electric hoist, the net height of the lower door opening is not less than 8m. (Article 1 of GB26557-2011)

Test conclusion.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.

Horizontal lead screw mechanical electricity

When the landing door is closed, the full width of the lifting passage opening should be covered.

The end height of the guide rail frame above the high attachment point should comply with the provisions of the user manual.

index.The end height of the guide rail frame above the high attachment point should comply with the provisions of the user manual.

When adding hydraulic oil, it is also necessary to pay attention to the structure of the oil cylinder. Some oil cylinders are relatively complex internally, and how many lifting operations need to be carried out during filling to fully fill each position of the hydraulic oil. Therefore, when filling, try to add as much as possible, and then test and run the machine empty to see if it reaches the rated position.

The net height of the landing door opening should not be less than 8m, 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, 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.

Li Shi.With the continuous improvement of urbanization level in China the number of high-rise buildings in urban areas has sharply increased, and the height of buildings has also continued to grow. This has created a demand for high-altitude lifting platform vehicles. Therefore, in order to meet the needs of the domestic market and the public, efforts will inevitably be made to design and produce high-altitude lifting platform vehicles.

The use of standard section connecting bolts should comply with the user manual and specification requirements.

The oil cylinder and sealing components are made of imported components to solve the problem of unstable oil pressure and oil leakage of components for customers.
