ZhongshanFour 
Zhongshan2 metall equipped with imported high-quality pump stations, which can also be selected according to customer requirements to meet customer ideal requirements.
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 descent
Zhongshan.The usual operation of landing and docking.
The scaffolding of the parking platform should be laid tightly and firmly.
.Setting requirements: For construction electric elevators that operate in multiple shifts, the handover system should be implemented, and drivers should fill out the handover record form according to the standard requirements. The driver should conduct a pre shift inspection and confirm that there are no errors before starting the machine for operation.
The wall bracket of the construction electric elevator should be intact and reliably fixed, and its attachment distance, wall bracket spacing, and end height must comply with the requirements of the 'User Manual'. The angle between the plane of the wall bracket and the normal direction of the attachment surface should not exceed 8 degrees;. When the attachment device does not meet the requirements of the 'User Manual' due to conditions, its calculation sheet, design, and production materials should be confirmed by the manufacturer or reviewed by the technical leader of the installation unit, and verified by experts.
Setting requirements: The layout and installation of all cables and wiring of electric elevators should be able to prevent mechanical damage.
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.
Lower limit switch: In normal working state, before the suspension cage touches the buffer, the lower limit switch first acts.
Setting requirements: The quality of the standard section should meet the requirements of the product manual. Before installing the construction electric elevator, all components should be inspected and standard sections and other components with severe wear and deformation should be replaced.
Quality documents.Buffer. In order to increase the energy for the car to hit the top or sink to the bottom. Remove rubber or sponge from the buffer and cabin to increase their impact energy; Rope groove slipping and other accidents caused the car to suddenly fall, resulting in a safety clamp. To prevent breakage of the lifting wire rope. A safety clamp that can simultaneously cut off the power supply and stop the car from falling should be removed from the car. A car without safety tongs is not allowed to ride or carry people. If it is a simple electric elevator, there should be a safety device (such as a safety stop pin) to prevent people from suddenly falling when loading and unloading goods in the car; Electric elevators with three or more floors (including three floors) for passengers or passengers.
Small safe operation distance: Circuit voltage (kV) of external power lines<11~1035~110220330~550 Small safe operation distance (m) 4681015 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.
Work is essential, and the main protective accessories include safety belts, guardrails, protective covers, platforms and stairs, etc.
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 descent
details.In order to meet the needs of contemporary audiences and achieve perfect effects, in addition to lighting and sound, stage machinery is particularly important on the stage. On the stage, there are suspension rods, suspension points, lighting bridges, lighting suspension cages, and fire curtains. Under the stage, there are lifting platforms, car platforms, turntables, and lifting orchestras. Some lifting platforms are equipped with turntables, or there are lifting platforms in the turntables. Various types of lifting platforms are equipped in professional opera houses, drama theaters,ZhongshanElectric self-propelled elevator, and many internationally renowned music halls. It has the functions of quickly changing scenery, meeting the needs of stage craft layout, meeting the needs of stage design and choreographers, creating special atmosphere and effects, and changing the stage form according to the needs of the performance.
Greater than 0.04s; When the hydraulic buffer is used, the oil level shall be checked, and the action of the hydraulic buffer shall be monitored by the Electrical safety switch. When the hydraulic buffer is compressed, making high-altitude operations easier
Later,ZhongshanElectric mobile elevator,ZhongshanExternal wall electric elevator, 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.
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, it is allowed to lower the height of the lower door opening when the net height of the building entrance is less than 0m, but in any case, the net height of the lower door opening is not less than 8m.
