Construction electric elevators outside the lightning protection rangeManual pump: When the system malfunctions,Check the starter potential when the lifting table is not raised or the voltage is too low when the motor load is working. Voltage hydraulic range allowed&When the wall bracket cannot meet the requirements of the construction site, it should be designed and calculated separately.Vyskov,Electric elevators used in various places.Setting requirements: The layout and installation of all cables and wiring of electric elevators should be able to prevent mechanical damage.The spacing between wall brackets and the height of guide rails above the high attachment point should comply with the requirements of the user manual.
The bearing capacity of the building structure at the attachment point of the wall bracket should meet the requirements specified in the user manual for construction electric elevators.The down travel (limit) switch should be of the automatic reset type.Setting requirements: The verticality deviation of the installation of the guide rail frame of the construction electric elevator should comply with the requirements of the user manual and specifications, as specified in the above table.Quality improvement,It is understood that the scissor type lifting platform is a widely used specialized equipment for high-altitude operations. Its shear fork mechanical structure provides high stability for the lifting platform, wide working platform, making the range of high-altitude operations larger and suitable for multiple people working simultaneously. The lifting power is divided into V, V or V power supplies, diesel engines, using Italian and domestic hydraulic pump stations, and the table top is equipped with anti slip insulation buckle plates, which have anti slip,UdenHuanghua, insulation, and safety features. Please rest assured to use.The list of materials for making landing doors is as follows: Table : List of materials for making landing doors. Landing doors should be installed at the entrance of each landing station, and the landing doors should function properly.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.
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,UdenYingze, family dormitories, andVariable cost,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.If the set screw is loose, be sure to pin it tightly to prevent accidents caused by the shaft pin falling off. Hydraulic oil should be kept clean and replaced every months.The hydraulic oil forms a certain pressure by the vane pump, and enters the lower end of the hydraulic cylinder through an oil filter, explosion-proof electromagnetic directional valve, throttle valve hydraulic control one-way valve, and balance valve, causing the hydraulic cylinder to move upwards and lift heavy objects. The return oil at the upper end of the hydraulic cylinder returns to the oil tank through the explosion-proof electromagnetic directional valve, and its rated pressure overflow valve is adjusted. The pressure gauge observes the reading value on the pressure gauge. The downward movement of the hydraulic cylinder (i.e. lowering of heavy objects).Uden, the form of the stage can be changed. For example, using an orchestra pit lift can combine a framed stage with a large lip or even an extended stage. In an experimental theater using a lift can make the theater have various forms such as an end stage, an extended stage, an island stage, an intermediate stage, a T-shaped stage, the driver of the construction electric elevator should inspect the construction electric elevator according to the requirements of the user manual and specifications, record the inspection results, and report any problems found to the user unit.Small 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.
The quality is very good, exactly the same as the seller’s description, very satisfied, really like it, completely exceeding expectations, the delivery speed is very fast, the packaging is very carefu
To live up to the boss's expectations of me, I will definitely write down my own evaluation objectively, fairly and truthfully, UdenSoest is indeed very good, thank you!!!
The first time I found what I wanted UdenSoest, I was in a good mood! Boss, come on, I hope to continue to make good products.
