According to the needs of different performance genres， the form of the stage can be changed. For example， using an orchestra pit lift can combine a framed stage with a large lip or even an extended stage. In an experimental theater， using a lift can make the theater have various forms such as an end stage， an extended stage， an island stage，LiaoningElectric hydraulic elevator， an intermediate stage， a T-shaped stage， or a hall.
Spiral electric lifting mechanism: With all the functions of a regular lifting platform， the main feature is that the equipment occupies a small foundation pit and has a large stroke. The equipment has a height of only -mm and a travel distance of up to m. It is particularly suitable for buildings with stages built on two or more floors due to space constraints.
LiaoningStop the suspension cage.
For customers to use and operate the lifting platform for a long time， the editor briefly introduces how to maintain and repair the lifting platform: First of all， normal maintenance is mainly focused on prevention， resulting in costly repairs.
VenezuelaThe landing door should be in a normally closed state. Without the permission of the construction electric elevator driver， the landing door shall not be opened.
The end height of the guide rail frame above the high attachment point should comply with the provisions of the user manual.
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.
The landing door should meet the requirements of the specifications and achieve standardization.
Safety devices: Electric elevators for construction should be equipped with overload detection devices. When the load inside the cage exceeds % of the rated load capacity， the overload detection device will give a warning signal inside the cage，
It is reported that a fixed electric elevator has good lifting stability and can only be used for fixed operations， making high-altitude operations easier
Welcome calls When the foundation is set on the roof or floor structure， the bearing capacity of its supporting structure should be checked.
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， special atmosphere and effects can be created. Even simple stage machinery often participates in performance activities a better highlighting effect can be achieved in various performances. According to the needs of the plot， 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.
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，LiaoningElectric mobile elevator，LiaoningElectric elevator， the lifting platform is driven by electrical energy and lifted by the hydraulic system. During operation， it is necessary to avoid irregular operations. To ensure the normal and orderly operation of the lifting platform and achieve the ideal unloading level， timely inspection of various functions is essential.
The detailed reason why water cannot be used to flush the hydraulic station is that doing so will corrode the oil tank in the hydraulic station， and once water is mixed in the hydraulic station， the damage to the hydraulic system is very large. Therefore， it will simply form pipeline corrosion， water vaporization， and other phenomena that can cause adverse effects or results for hydraulic electric elevators. Therefore， it is necessary to prevent such actions to ensure the normal operation and service life of the hydraulic station.
Small safe operation distance: Circuit voltage (kV) of external power lines<~~~ Small safe operation distance (m) Setting requirements: A small safe distance should be maintained between the outer edge of the construction electric elevator and the edge of the external overhead power line.
LiaoningLow 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， etc.， and the production should meet the design requirements.
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
From the above comparison， it can be seen that hydraulic electric lifting mechanisms have stable lifting， low noise， long service life large load bearing capacity， and are relatively simple， making them suitable for use in stage equipment.
