Mechanical devices controlled by cage movement should not be used to open or close the landing door.Pipeline rupture valve: When the hydraulic system pipeline ruptures and the car stalls and descends, it can automatically cut off the oil circuit and stop descentRamsey,Construction electric elevators must be equipped with lifting cages and reusable buffers, and comply with regulatory requirements.Setting requirements: The landing door should be standardized and tooled.PR é maisier,Every theater is a public place with a large number of people, and safety considerations should be taken into account in stage design. According to relevant national regulations, in order to prevent accidents caused by the crushing of electric elevators or improper control by drivers. Electric elevators should be equipped with the following necessary safety devices to ensure that the car of the electric elevator stops rising or falling in a timely manner.The motor of the hydraulic guide rail lifting platform is set around the wellbore occupying a relatively small area, when the net height of the building entrance is less than m improving the utilization rate of the wellbore area.The full height landing door should meet the following requirements: the net height of the landing door opening should not be less than m. In special circumstances, 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 m. (Article of GB-)
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 degree position until it is closed, and then turn the transmission handwheel to lower the plug and achieve sealing.Construction electric elevators should be equipped with travel limit switches, as follows: automatic reset type upper and lower limit switches should be installed on construction electric elevators, but the upper and lower limit switches should not be triggered as highSmall safe operation distance: Circuit voltage (kV) of external power lines<~~~ Small safe operation distance (m) 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.Encyclopedic knowledge,RamseyElectric hydraulic elevator 15 meters,Horizontal lead screw mechanical electricitySecondly, for the replacement of hydraulic oil on the lifting platform, it is recommended to replace it every three months. If the frequency of use is not high, and after changing the hydraulic oil, it must be automatically lifted and lowered to 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.During normal operation, the horizontal distance between the closed cage door and the closed landing door should not exceed mm. 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 mm.
Every theater is a public place with a large number of people, in order to prevent accidents caused by the crushing of electric elevators or improper control by drivers. Electric elevators should be equipped with the following necessary safety devices to ensure that the car of the electric elevator stops rising or falling in a timely manner.Workshop cost,Setting requirements: The layout and installation of all cables and wiring of electric elevators should be able to prevent mechanical damage.Setting requirements: A limit switch should be set at both the upper and lower ends of the stroke,Ramsey10 meter self-propelled elevator,RamseyMobile, which should be able to cut off the power supply before the suspension cage and other mechanical stop devices (such as buffers), so that the suspension cage can stopThe quality of the standard section should comply with the product manual and specification requirements.Ramsey,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.The entrance of each landing platform must be equipped with a landing door, which must open towards the landing platform side, and the door bolt must be set on the side next to the construction electric elevator.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 mm and there is no effective protection from other structures, the side protection device for the landing entrance should be equipped.
