WeltElectric tthe number of high-rise buildings in urban areas has sharply increased
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.
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.
Welt.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,
Installation and dismantling personnel and drivers should hold certificates to work.
.The landing door should be in a normally closed state. Without the permission of the construction electric elevator driver, the landing door shall not be opened.
The landing door should be in a normally closed state. Without the permission of the construction electric elevator driver, the landing door shall not be opened.
During the use period, the user unit should organize professional technical personnel to inspect the construction electric elevator monthly according to the standard requirements, and record the inspection results.
When the wall bracket adopts non matching standard products, design calculations should be carried out.
When adding hydraulic oil,WeltElectric tricycle elevator, 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.
Steel wire ropes, pulleys, 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
Interpretation and observation.During normal operation the horizontal distance between the closed cage door and the closed landing door should not exceed 150mm. Otherwise, measures should be taken to make it meet the requirements, or side protection devices at the entrance of the landing station that meet the requirements should be equipped. The distance between any opening between the side protection device and the hanging cage or landing door should not exceed 150mm.
The quality of the standard section should comply with the product manual and specification requirements.
Secondly, for the replacement of hydraulic oil on the lifting platform, 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.
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.
Convenient and efficient.News Abstract: The development of the lifting platform industry will continue to grow in recent years! With the continuous development of electric lifting machinery for high-altitude operations in recent years, the products of electric lifting platform vehicles have been continuously improved and various new technologies and materials have emerged, making the further development of lifting platform vehicles possible.
Construction electric elevators should be equipped with emergency stop switches and comply with regulatory requirements.
The use of standard section connecting bolts should comply with the user manual and specification requirements.
Welt.After the electric elevator passes the inspection,WeltBasement electric elevator,WeltSecond floor electric elevator, 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.
Setting requirements: The anti loosening and anti loosening parts between the connecting parts should comply with the provisions of the user manual and should not be replaced by other objects. For connecting bolts with pre tightening requirements, it is advisable to place the screw at the bottom and the nut at the top.
Setting requirements: The wall bracket should use the manufacturer's matching standard products.
