toray 22ov eleThe 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)
The hydraulic oil enters the upper end of the hydraulic cylinder through the explosion-proof electromagnetic directional valve, and the return oil from the lower end of the hydraulic cylinder returns to the oil tank through the balance valve, hydraulic control one-way valve, throttle valve, and explosion-proof electromagnetic directional valve. To ensure a smooth descent of heavy objects and safe and reliable braking,toray Electric background axis elevator, so that the descent speed does not change due to heavy objects. The throttle valve regulates the flow rate and the ascending and descending speed.
toray .Fully autonomous lifting is widely used in various high-altitude work fields such as factory maintenance, airport maintenance, street light maintenance, and so on; How to use electric elevators correctly to extend the service life of the equipment and be flexible
Manual pump: When the system malfunctions, the operating failure rate can be reduced to a low level.
Later, when there is a major malfunction of the lifting platform, 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.
Civil engineering advantages: The pit depth of the guide rail type lifting platform is generally around 150-300mm, and the top layer is not affected. It can be customized according to the location and environment.
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.
Correct use can also greatly improve work efficiency. So how should it be used?
High lifting height, using side mounted oil cylinders, stable operation, noise free,toray Electric small elevator, easy maintenance, and longer service life.
knowledge.The landing door should meet the requirements of the specifications and achieve standardization.
Work is essential, and the main protective accessories include safety belts guardrails, protective covers, platforms and stairs, etc.
Acceptance: Concrete strength grade C30, strength testing report.
Construction electric elevators outside the lightning protection range
retailer.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
Platform.
Installation and dismantling personnel and drivers should hold certificates to work.
toray .Principle of electric elevator rotary valve: When the electric elevator rises, the rotary valve will automatically open. To close the plug valve,toray Curved arm electric elevator, 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.
Speed limiter. To prevent the driving speed from exceeding the normal speed. A speedometer should be installed (not required for floors below or including the second floor), which is an individual mechanism that is integrated with a safety clamp; The entrance and exit of the passenger compartment should be equipped with safety doors. Public places, family dormitories, which should cover the opening with its full width, and should not open towards the lifting passage.
