Flat screw mechanical electric lifting mechanism: The lifting platform of this structure has the advantages of small civil engineering coordination, shallow foundation pit required, large stroke, stable operation, low noise, accurate positioning, and low cost. Adopting a horizontal screw drive and a scissor fork structure to achieve the lifting motion of the table, it can be stopped arbitrarily within the range of travel.
With the continuous improvement of urbanization level in China, 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.
Masles.Non automatic reset upper and lower limit switches should be installed at both the upper and lower ends of the stroke, which should be able to cut off the power supply before the suspension cage and other mechanical stop devices (such as buffers),
The distance between the electric hoist and overhead line in Electrical safety construction shall meet the specification requirements, otherwise protective measures shall be taken.
.Mechanical devices controlled by cage movement should not be used to open or close the landing door.
Construction electric elevators outside the lightning protection range
Low power consumption: When the hydraulic guide rail lifting platform descends, it is driven by the pressure generated by its own weight, greatly saving energy and reducing consumption.
Operating cost advantage and low failure rate: Due to the use of advanced hydraulic systems and good methods, the operating failure rate can be reduced to a low level.
Honest service.Later, when there is a major malfunction of the lifting platform,MaslesFloor electric elevator, it should be repaired by professional personnel as soon as possible. After the malfunction occurs, it should not be used again to avoid accidents, personnel and property losses.
Installation position of upper limit switch: Under normal working conditions,MaslesScissor fork electric elevator, the distance between the upper limit switch and the upper limit switch is 0.15m for SC type construction electric elevators, and 0.15m for SS type construction electric elevators (person)
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, and then turn the transmission handwheel to lower the plug and achieve sealing.
Masles.The bearing capacity of the ground under the concrete foundation plate should be greater than 0.15Mpa.
The quality of the standard section should comply with the product manual and specification requirements.
When the landing door is closed, the full width of the lifting passage opening should be covered.
