Hu GewenSelf propelled electric elevatorDissemination methods should be adapted to local conditions

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.

Construction electric elevators outside the lightning protection range

Hu Gewen.The water cooling of hydraulic stations is generally tubular water cooling. The selection is based on the heat load to calculate the heat exchange area while the air-cooled electric elevator uses an air cooler to calculate the heat exchange capacity based on the heat load. Then, the selection calculation is carried out under the condition of satisfying the flow rate. So, these two types of cooling are different and have significant differences.

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,Hu GewenElevator platform electric, 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,Hu GewenElectric mobile hydraulic elevator, 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.

.When the door is closed, except for the gap between the lower part of the door that should not exceed 35mm, any through-hole and opening size related to the distance between any door and adjacent moving parts, as well as the gap around the door or the gap between parts, should comply with the provisions of Table 4 of GB 23821-2009.

Small safe operation distance: Circuit voltage (kV) of external power lines<11~1035~110220330~550 Small safe operation distance (m) 4681015 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.

Principle of electric elevator rotary valve: When the electric elevator rises, the rotary valve will automatically open. To close the plug valve, it is necessary to first turn the handle to turn the plug to a 90 degree position until it is closed, and then turn the transmission handwheel to lower the plug and achieve sealing.

Setting requirements: Before starting work every day and changing shifts, record the inspection results, and report any problems found to the user unit.

Limit switches should be triggered directly by the movement of the suspension cage or its related components.

When applying a normal force of 300N to any position on either side of the door using a rigid 5000mm2 square or circular flat surface in the locked position of the landing door, the door should be able to withstand and have no deformation; - Deformation not exceeding 30mm; After the test, a torque wrench or special tool should be used to accurately tighten the bolts to the specified torque value according to the specified tightening sequence. When installing standard section connecting bolts, it is advisable to place the screw at the bottom and the nut at the top.

During normal operation the horizontal distance between the closed cage door and the closed landing door should not exceed 150mm. Otherwise, or side protection devices at the entrance of the landing station that meet the requirements should be equipped. The distance between any opening between the side protection device and the hanging cage or landing door should not exceed 150mm.

Setting requirements: For construction electric elevators that operate in multiple shifts, the handover system should be implemented, the protective measures taken should comply with the specification requirements.

Setting requirements: Buffers should be installed below the suspension cage and counterweight running channel.

Manual pump: When the system malfunctions,Hu GewenElectric scissor lift, the manual pump can be operated to pump high-pressure oil to raise the car to the nearest floor position

Hu Gewen.The wall bracket of the construction electric elevator should be intact and reliably fixed, and its attachment distance, wall bracket spacing, 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, design, and production materials should be confirmed by the manufacturer or reviewed by the technical leader of the installation unit, and verified by experts.

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.

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.
