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 returns to the oil tank through the balance valve, hydraulic control one-way valve throttle valve, 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.
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.
Ostrovinka.In addition to fixed modes, there are also types of car mounted mobile devices. As the name suggests, this type of lifting device is a combination of lifting equipment and car mounted systems. It is very flexible to move, and of course, it is better to use it. For example, there are such lifting devices in airports, and car stations or sports stadiums may also be equipped with such devices, as they can be moved, but can be used wherever lifting operations are required. For example, when installing outdoor advertisements, some advertisements are relatively high in height. At this time, mobile lifting equipment can be used to transport billboards or staff to the designated height for work. This type of equipment can also be divided into two types based on the driving mode: hydraulic lifting and electric lifting. The so-called hydraulic lifting is the use of hydraulic oil to drive and reach a specified height. The electric mode is driven by a motor or teeth to lift to a certain height. However, currently, hydraulic lifting platforms are more widely used.
During loading and unloading, the horizontal distance between the edge of the cage door and the edge of the landing station should not exceed 50mm.
.To meet the needs of stage craftsmanship and layout; Product; In the music and dance theater stage arranged in a zigzag pattern, auxiliary lifting platforms are often arranged in front, back, left, and right of the main stage lifting platform. The side and rear auxiliary lifting platforms are used for the smooth opening of the side platform and rear vehicle turntable, so that the entire platform does not have a height difference, ensuring the safety of the cast members.
Vertical lead screw electric lifting mechanism: Adopting a lead screw transmission method, and different steps can be formed within the travel range to meet the needs of meetings and performances; Pavilion, Terrace Tower, Pavilion; Ideal props.
Use floor doors and cage door devices on construction sites where conditions permit.
The pump body adopts an integrated pump station, all equipped with imported high-quality pump stations, which can also be selected according to customer requirements to meet customer ideal requirements.
The occurrence of.
The landing door should meet the requirements of the specifications and achieve standardization.
equipment maintenance .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.
The full height landing door should meet the following requirements: the net height of the landing door opening should not be less than 0m. In special circumstances, 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 counterweight guide rail should meet the specification requirements.
Work is essential, and the main protective accessories include safety belts, guardrails, protective covers, platforms and stairs, etc.
resources.In order to meet the needs of contemporary audiences and achieve perfect effects, in addition to lighting and sound, stage machinery is particularly important on the stage. On the stage, there are suspension rods, suspension points, lighting bridges, lighting suspension cages, and fire curtains. Under the stage, there are lifting platforms car platforms, turntables, and lifting orchestras. Some lifting platforms are equipped with turntables, or there are lifting platforms in the turntables. Various types of lifting platforms are equipped in professional opera houses, dance theaters, drama theaters, and many internationally renowned music halls. It has the functions of quickly changing scenery meeting the needs of stage craft layout, meeting the needs of stage design and choreographers, creating special atmosphere and effects, and changing the stage form according to the needs of the performance.
Mobile electric elevators are divided into: four wheel mobile lifting platform, two wheel traction lifting platform, car modified lifting platform, manual lifting platform,OstrovinkaSmall electric elevator,OstrovinkaElectric self-propelled elevator,OstrovinkaTwo phase electric elevator, manual lifting platform, and AC/DC dual purpose lifting platform
Use floor doors and cage door devices on construction sites where conditions permit.
Ostrovinka.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.
Setting requirements: The guide rail should be rigid and flexible components such as wire ropes or chains should not be used.
The bearing capacity of the ground under the concrete foundation plate should be greater than 0.15Mpa.
