CologneSmall eDrivers of construction electric elevators should hold special construction operations and are not allowed to operate without a certificate.
Setting requirements: The guide rail should be rigid and flexible components such as wire ropes or chains should not be used.
Cologne.The downward movement of the hydraulic cylinder (i.e. heavy object lowering). 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 passes through the balance valve, hydraulic control one-way valve, energy-saving valve and explosion-proof electric valve
Setting requirements: Each landing entrance should be equipped with a landing door, which should cover the opening with its full width,CologneElectric boom elevator, when the net height of the building entrance is less than 0m, it is allowed to lower the height of the lower door opening,CologneElectric hydraulic platform elevator, but in any case, the net height of the lower door opening is not less than 8m. (Article 1 of GB26557-2011)
Drivers of construction electric elevators should hold special construction operations and are not allowed to operate without a certificate.
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 high
Setting requirements: The layout and installation of all cables and wiring of electric elevators should be able to prevent mechanical damage.
Good quality.Spiral electric lifting mechanism: With all the functions of a regular lifting platform, the main feature is that the equipment occupies a small foundation pit and has a large stroke. The equipment has a height of only 200-500mm and a travel distance of up to 14m. It is particularly suitable for buildings with stages built on two or more floors due to space constraints.
Safety grounding device. In order to protect against electrical equipment. The metal casing of electrical equipment and the metal structure of electric elevators should be equipped with a safety grounding device. The grounding wire should operate multiple wires, and the neutral wire should not be arbitrarily held as a safety grounding wire. Its grounding resistance should not exceed 4 ohms; The power supply of the electric elevator can be cut off.
When the wall bracket adopts non matching standard products,CologneElectric rope climbing machine elevator, design calculations should be carried out.
Speed limit wire rope switch. When the speed limit wire rope trips or breaks. Make the electric elevator unable to start.
The cost is reasonable.When the wall bracket cannot meet the requirements of the construction site, it should be designed and calculated separately.
Construction electric elevators should be equipped with lower limit switches that are sensitive and reliable.
Stage equipment safety door. To prevent personnel from extending their heads, hands, and feet out of the shaft and objects from falling into the vertical shaft. Its vertical position should be closed, its cabin should be full of doors, passenger car doors, and car roof doors not being closed.; Door interlocks should be installed on both the vertical and passenger compartment doors.
Cologne.Setting requirements: The main connection methods between the wall bracket and the building include: connecting the wall bracket with the embedded parts on the wall; Fix with wall bolts; Embedded bolts; Welding with steel structures.
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 bearing capacity of the ground under the concrete foundation plate should be greater than 0.15Mpa.
