The counterweight guide rail should meet the specification requirements.
To meet the needs of choreographers and choreographers in different plays, different heights of the lifting platform can be used to change the shape of the stage according to the requirements of the choreographers and choreographers, in order to adapt to the requirements of the plot for the scenery or venue, and save manpower and material resources for setting up. By using the tilting device of the lifting platform to form a tilted platform, a better highlighting effect can be achieved in various performances. According to the needs of the plot, special atmosphere and effects can be created. Even simple stage machinery often participates in performance activities, creating unexpected atmosphere and effects according to the needs of the plot. For example, using the low-speed descent of the lifting platform to represent a sunken ship in the sea, using the valves on the lifting platform and the sudden disappearance and appearance of actors on the lifting platform.
Ulm.Unloading platform and attached electric construction platform, etc.
The distance between the electric hoist and overhead line in Electrical safety construction shall meet the specification requirements, and the return oil from the lower end of the hydraulic cylinder returns to the oil tank through the balance valve, hydraulic control one-way valve,UlmDedicated electric elevator,UlmUsed electric elevator platform, throttle valve, and explosion-proof electromagnetic directional valve. To ensure a smooth descent of heavy objects and safe and reliable braking, a balance valve is installed on the return oil circuit to balance the circuit and maintain pressure, so that the descent speed does not change due to heavy objects. The throttle valve regulates the flow rate and the ascending and descending speed.
Setting requirements: The layout and installation of all cables and wiring of electric elevators should be able to prevent mechanical damage.
Monthly maintenance and inspection of hydraulic lifting platform rollers, intermediate shafts and bearings, oil cylinder pin shafts and bearings, boom hinge shafts and bearings for wear. Add some oil to each part to extend the service life of the lifting platform bearings. The quality and level of hydraulic oil. The lifting platform should be raised throughout the entire process, and at this position, the hydraulic ground should be 40-50 millimeters higher than the bottom of the box. If the hydraulic oil becomes dark, sticky, it should be replaced in a timely manner (32 # hydraulic oil). Annual maintenance and inspection of all hydraulic pipelines and joints of the lifting platform. The pipeline must not be damaged, and the joints must not be loose. All joints must be tightened. Remove and disassemble the lowering valve of the lifting platform, blow out the plunger with compressed air then install it and reinstall it. Drain and discard the hydraulic oil, tighten the joint remove the oil filter, clean it with compressed air, and then return it to the oil tank and connect the pipeline.
Implementing multiple shifts of homework should fill in and submit records according to regulations.
The usual operation of landing and docking. The installation position of the upper limit switch should comply with the following: when the lifting speed is less than 0.8m/s, the upper safety distance L left after the upper limit switch is triggered by the hanging cage should not be less than
Before operating the construction electric elevator,UlmElectric elevator lifting by 4 meters, the door may not meet the above requirements, but safety should be maintained.
Setting requirements: The landing door should be standardized and tooled.
Manual pump: When the system malfunctions, the manual pump can be operated to pump high-pressure oil to raise the car to the nearest floor position
Where is it.Speed limit wire rope switch. When the speed limit wire rope trips or breaks. Make the electric elevator unable to start.
The cleanliness of the hydraulic station is an important aspect of the electric elevator hydraulic station, so it should not be taken lightly. And from a professional perspective, there are relevant rules and requirements that should be referred to in the specification manual, so as to have a correct understanding and know how to achieve good cleanliness.
The setting of the cable guide frame should comply with the user manual and regulatory requirements.
Ulm.Setting requirements: Before starting work every day and changing shifts, 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.
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.
In addition to ground protective fences, low level doors can be used. Low level doors should meet the following requirements: the height of the door should be between 1m and 2m. And there should be at least protective railings, a half height middle crossbar, and a toe board at least 150mm above the ground.
