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，ColmarTwo phase electric elevator，ColmarElectric elevator lifting platform， 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.
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.
ColmarCheck whether the sealing of components such as the oil cylinder， oil pipe， and motor of the aluminum alloy electric elevator is good and whether there is any air leakage.
The full height landing door should meet the following requirements: the net height of the landing door opening should not be less than m. In special circumstances， when the net height of the building entrance is less than m， it is allowed to lower the height of the lower door opening， but in any case， using side mounted oil cylinders， stable operation， easy maintenance， and longer service life.
When the landing door is closed， the full width of the lifting passage opening should be covered.
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， 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.
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.
The pressure joint between the pipe joint and the rubber hose fails prematurely， causing oil leakage or pipe explosion. The oil temperature rises due to frequent action of the overflow valve.
The bearing capacity of the ground under the concrete foundation plate should be greater than .Mpa.
Packaging strategyBefore operating the construction electric elevator， routine inspections should be carried out according to regulations and inspection records should be filled out.
Installation and dismantling personnel and drivers should hold certificates to work.
For customers to use and operate the lifting platform for a long time， normal maintenance is mainly focused on prevention， especially if any damage or malfunction is detected and corrected or repaired in a timely manner. Careful inspection and maintenance at this time can save costs and avoid larger problems， resulting in costly repairs.
Setting requirements: Each landing entrance should be equipped with a landing door，ColmarElevator electric elevator， which should cover the opening with its full width， and should not open towards the lifting passage.
manufacturerEspecially suitable for steel structured factories， suitable for both indoor and outdoor installation.
It is strictly prohibited to use travel limit switches as switches to stop operation.
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.
ColmarAfter the electric elevator passes the inspection， the user unit shall organize the leasing unit， installation unit and supervision unit to conduct acceptance. For the implementation of construction general contracting， the acceptance shall be organized by the construction general contracting unit. The acceptance form should be signed by the relevant responsible person.
Setting requirements: The guide rail should be rigid and flexible components such as wire ropes or chains should not be used.
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 . meters.
