The net height of the landing door opening should not be less than 8m, and the difference between the net width and the outlet width of the cage door should not exceed 120mm. When the floor door is closed, except for the gap between the lower part of the door that should not exceed 35mm, the size of any through-hole and opening related to the distance between any door and adjacent moving parts, as well as the gap around the door or between parts, should comply with the provisions of Table 4 of 'Mechanical Safety - Safety Distance to Prevent Upper and Lower Limbs from Touching Dangerous Areas' GB23821-2009.
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
Dalas.Savings, rate of increase and decrease. To ensure safe and reliable braking and prevent accidents,DalasElevator electric micro, a hydraulic control one-way valve, also known as a hydraulic lock, 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.
.The landing door should meet the requirements of the specifications and achieve standardization.
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, 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, 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.
Secondly, for the replacement of hydraulic oil on the lifting platform, it is recommended to replace it every three months. If the frequency of use is not high,DalasElectric fixed elevator, it can be replaced once a year. The hydraulic oil must be clean, and after changing the hydraulic oil,DalasHand push electric elevator, it must be automatically lifted and lowered 2 to 3 times to ensure that the air in the oil cylinder is completely discharged, and ensure that the lifting platform can be lifted to the rated lifting height.
Stop the suspension cage.
The connection method and angle between the wall bracket and the building structure should comply with the requirements of the user manual.
Inspection standard.Setting requirements: The guide rail should be rigid and flexible components such as wire ropes or chains should not be used.
When the foundation is set on the roof or floor structure, the bearing capacity of its supporting structure should be checked.
The oil cylinder and sealing components are made of imported components to solve the problem of unstable oil pressure and oil leakage of components for customers.
Construction electric elevators outside the lightning protection range
Management Department.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.
Try to use this equipment in areas with wind force less than level five and avoid using it when the wind force is too strong to avoid accidents.
Protective measures should comply with regulatory requirements.
Dalas.Stage equipment safety door. To prevent personnel from extending their heads, and feet out of the shaft and objects from falling into the vertical shaft. Its vertical position should be closed hands, its cabin should be full of doors, and the height of the hoistway (hall door) should not be less than 8 meters; The electric door opening and closing switches should be removed from the vertical and passenger compartment doors. In order to prevent accidents caused by vertical, passenger car doors, and car roof doors not being closed.; Door interlocks should be installed on both the vertical and passenger compartment doors.
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.
Chain type electric lifting mechanism: With a good guiding mechanism, it can ensure that the equipment does not tilt during operation. Gear and rack electric lifting mechanism: precise transmission and high cost.
