The use of a lifting platform as a tool for storing performance blankets, soft scenery, etc. In some theaters, there is a soft scenery storage lifting platform located at an appropriate location on the stage for the storage of blankets, soft scenery, etc.
Setting requirements: The spacing of wall brackets along the vertical direction should comply with the provisions of the user manual.
Cologne.Is there a relevant rule requirement for the cleanliness of hydraulic stations?
When the horizontal distance between the edge of the cage and the edge of the landing or between the cage and the landing door is greater than 150mm and there is no effective protection from other structures, the side protection device for the landing entrance should be equipped.
.When a rigid 5000mm2 square or circular flat surface is applied with a normal force of 600N to either side of the door, but safety should be maintained.
Low level doors should be equipped with interlocking devices that can verify their closed and locked positions. The action of this interlocking device should be at the entrance of the cage. Simple use should not interfere with the operation of the interlocking device. The attached wall bracket should use matching standard products. When the wall bracket cannot meet the requirements of the construction site, it should be designed separately. The design of the wall bracket should meet the requirements of component stiffness, strength, stability, etc.,CologneSimple electric elevator, and the production should meet the design requirements.
Advantages of electric elevator rotary valve: Simplify the installation of electric elevator pipelines; The operation is more convenient, and the valve can be opened and closed at any time; The installation of a rotary valve reduces the friction of the sealing components; Compact structure, small size, and space saving; Increased the service life of electric elevator pipelines and solved the problem of easy oil leakage.
Setting requirements: The foundation and foundation of the construction electric elevator should meet the requirements of the user manual. Before installing the construction electric elevator, the foundation should be inspected and accepted according to the requirements of the specifications. Only after passing the inspection can the installation be carried out.
When adding hydraulic oil, it is also necessary to pay attention to the structure of the oil cylinder. Some oil cylinders are relatively complex internally, and how many lifting operations need to be carried out during filling to fully fill each position of the hydraulic oil. Therefore, when filling,CologneFire electric elevator, try to add as much as possible and then test and run the machine empty to see if it reaches the rated position.
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, 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.
Promotion.Safety performance: Electric elevators not only have the safety device of traditional traction elevators, but also have an overflow valve to prevent excessive system pressure during upward movement
When a rigid 5000mm2 square or circular flat surface is applied with a normal force of 600N to either side of the door, the door may not meet the above requirements, but safety should be maintained.
Speed limit wire rope switch. When the speed limit wire rope trips or breaks. Make the electric elevator unable to start.
Secondly, for the replacement of hydraulic oil on the lifting platform, it is recommended to replace it every three months. If the frequency of use is not high, it can be replaced once a year. The hydraulic oil must be clean, and after changing the hydraulic oil, it must be automatically lifted and lowered 2 to 3 times to ensure that the air in the oil cylinder is completely discharged, maintain sufficient space,CologneElectric six meter elevator, and ensure that the lifting platform can be lifted to the rated lifting height.
The cheapest.When the distance between the outer edge of the construction electric elevator and the edge line of the external overhead power line cannot meet the requirements in the table above, effective protective measures should be taken.
The upward movement of the hydraulic cylinder involves lifting heavy objects, and the return oil from the upper end of the hydraulic cylinder returns to the oil tank through the explosion-proof electromagnetic directional valve. The additional pressure relief valve is used for adjustment, and the pressure gauge reads the value when observing the pressure gauge
Setting requirements: The layout and installation of all cables and wiring of electric elevators should be able to prevent mechanical damage.
Cologne.During the use period, the user unit should organize professional technical personnel to inspect the construction electric elevator monthly according to the standard requirements, and record the inspection results.
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, 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).
Low power consumption: When the hydraulic guide rail lifting platform descends, it is driven by the pressure generated by its own weight, greatly saving energy and reducing consumption.
