ShanghaiSmall The advantages and disadvantages of several commonly used electric lifting mechanisms are as follows: hydraulic electric lifting mechanisms: using hydraulic technology, smooth lifting and low noise.
Setting requirements: The layout and installation of all cables and wiring of electric elevators should be able to prevent mechanical damage.
Shanghai.The use of fully autonomous electric elevators can create more benefits and ensure safety in all aspects.
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.
.Operating cost advantage and low failure rate: Due to the use of advanced hydraulic systems and good methods, the operating failure rate can be reduced to a low level.
Construction electric elevators outside the lightning protection range
Braking. The brake limit switch for partial motion control of the electric hoist traction machine. Assembly that restricts the operation of the lift car when it is opened to a high or low position; If the limit switch controls the overtravel switch. When the car travels to a high or low position, it will take on the function of raising or lowering. In order to prevent the lift car from crashing or sinking,ShanghaiSelf propelled electric elevator, stage equipment should be dismantled with over travel switches that can cut off power and cannot be automatically reset, and installed in the machine room, rather than in the shaft; A buffer should be installed that can absorb the energy of the moving mechanism and reduce impact.
During the use period, the user unit should organize professional technical personnel to inspect the construction electric elevator monthly according to the standard requirements,ShanghaiElectric lifting scissor lift, and record the inspection results.
Unloading platform and attached electric construction platform, etc.
The foundation base or embedded parts should be fully embedded in the concrete foundation plate.
packing.The landing door should meet the requirements of the specifications and achieve standardization.
Operating cost advantage and low failure rate: Due to the use of advanced hydraulic systems and good methods, the operating failure rate can be reduced to a low level.
The entrance of each landing platform must be equipped with a landing door, which must open towards the landing platform side, and the door bolt must be set on the side next to the construction electric elevator.
Setting requirements: The landing door should be standardized and tooled.
Safety production.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.
Greater than 0.04s; When the hydraulic buffer is used,ShanghaiSmall and simple electric elevator, 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, the cage shall not
Setting requirements: The installation and dismantling workers, electricians, and other operators of construction electric elevators should have special construction operations.
Shanghai.The connection method and angle between the wall bracket and the building structure should comply with the requirements of the user manual.
Implementing multiple shifts of homework should fill in and submit records according to regulations.
Acceptance: Concrete strength grade C30, strength testing report.
