Safety grounding device. In order to protect against electrical equipment. The metal casing of electrical equipment and the metal structure of electric elevators should be equipped with a safety grounding device. The grounding wire should operate multiple wires, and the neutral wire should not be arbitrarily held as a safety grounding wire. Its grounding resistance should not exceed 4 ohms; The power supply of the electric elevator can be cut off.

Many theaters use a lifting platform as a vertical transportation tool for goods. The rear of the main stage or the end of the side stage in many theaters are equipped with a set container transportation lifting platform, which is used to vertically transport items from the ground to a designated location or even the stage plane. The lifting platform of the music pool is often used for transporting movable seats, etc.

Cannes .The downward movement of the hydraulic cylinder (i.e. heavy object lowering). 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 passes through the balance valve, hydraulic control one-way valve, energy-saving valve, and explosion-proof electric valve

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, an intermediate stage, a T-shaped stage, or a hall.

.The wall bracket of the construction electric elevator should be intact and reliably fixed, and its attachment distance,Cannes Self propelled electric elevator, and end height must comply with the requirements of the 'User Manual'. The angle between the plane of the wall bracket and the normal direction of the attachment surface should not exceed 8 degrees;. When the attachment device does not meet the requirements of the 'User Manual' due to conditions, its calculation sheet,Cannes Scissor fork electric lifting platform, design, and production materials should be confirmed by the manufacturer or reviewed by the technical leader of the installation unit and verified by experts.

Secondly, for the replacement of hydraulic oil on the lifting platform, and after changing the hydraulic oil it can be replaced once a year. The hydraulic oil must be clean, 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, and ensure that the lifting platform can be lifted to the rated lifting height.

Setting requirements: The layout and installation of all cables and wiring of electric elevators should be able to prevent mechanical damage.

Setting requirements: The guide rail should be rigid and flexible components such as wire ropes or chains should not be used.

The shutdown device (emergency stop switch) should be non automatic reset type.

Work is essential, and the main protective accessories include safety belts, guardrails, protective covers, platforms and stairs, etc.

quality index.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.

The connection method and angle between the wall bracket and the building structure should comply with the requirements of the user manual.

When the landing door is closed, the full width of the lifting passage opening should be covered.

Before installation, the installation unit should confirm that the foundation, foundation bearing capacity, embedded parts, and concrete strength report.

Focus on Development.The angle between the wall bracket and the horizontal plane should comply with the requirements of the user manual.

The usual operation of landing and docking.

Installation verticality deviation guide rail frame erection height concealed engineering acceptance form, h/mH≤ 7070100150H& gt; 200 verticality deviation/mm≤ (1/100h≤ 70≤ 90≤ 110≤ 130 pairs of steel wire rope construction electric elevators,Cannes Guide rail electric elevator, the verticality deviation of the guide rail frame should not exceed (5/1000) h.

Cannes .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

Mechanical devices controlled by cage movement should not be used to open or close the landing door.

Before operating the construction electric elevator, routine inspections should be carried out according to regulations and inspection records should be filled out.
