BielefeldElectConstruction electric elevators outside the lightning protection range
When the landing door is closed, the full width of the lifting passage opening should be covered.
Bielefeld.During maintenance or when problems occur, the power supply should be cut off in a timely manner. After lifting, the aluminum alloy electric elevator should be firmly fixed before maintenance can be carried out. It is strictly prohibited to operate with defects to avoid accidents.
There is no need to set up a computer room above the shaft like an elevator and the top floor height can be installed at least 2.5 meters.
.Construction electric elevators should be equipped with cable guide frames and comply with regulatory requirements.
Acceptance: Concrete strength grade C30, strength testing report.
The use of standard section connecting bolts should comply with the user manual and specification requirements.
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.
The device should be used within the valid calibration period and operate effectively and reliably. The anti fall safety device should have a valid inspection certificate (or inspection report), and the validity period should not exceed 1 year. Anti fall safety devices have been manufactured for five years
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.
assets.The safety notice board for construction electric elevators should be prominently placed on the hanging cage for the rated load capacity and rated number of passengers of the construction electric elevator. It is strictly prohibited to use construction electric elevators beyond the rated load capacity or rated number of passengers.
Steel wire ropes, and counterweight steel wire ropes shall comply with the following regulations: the characteristics of steel wire ropes shall comply with the requirements of General Purpose Steel Wire Ropes GB/T20118; Maintenance, wear,BielefeldPortable electric elevator, deformation,BielefeldThree phase electric 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 but in any case, the net height of the lower door opening is not less than 8m. (Article 1 of GB26557-2011)
The working principle of the aluminum alloy lifting platform is that hydraulic oil is composed of a vane pump to form a certain pressure, which 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
Setting requirements: For construction electric elevators with foundations installed on roof slabs, floors, or other lower suspended structures, the bearing capacity of the foundation support structure should be checked. Click here to download the construction technical information for free. Basic drainage facilities should be installed.
Bielefeld.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.
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.
Flat screw mechanical electric lifting mechanism: The lifting platform of this structure has the advantages of small civil engineering coordination, shallow foundation pit required, large stroke,Bielefeld10 meter electric elevator, stable operation, low noise, accurate positioning, and low cost. Adopting a horizontal screw drive and a scissor fork structure to achieve the lifting motion of the table, it can be stopped arbitrarily within the range of travel.
