During normal operation， the horizontal distance between the closed cage door and the closed landing door should not exceed mm. Otherwise， measures should be taken to make it meet the requirements 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 mm.
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 degree position until it is closed， and then turn the transmission handwheel to lower the plug and achieve sealing.
Azzo The counterweight steel wire rope should be equipped with an anti loosening device that is sensitive and reliable.
When applying a normal force of N to any position on either side of the door using a rigid mm 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 mm; After the test， it worked normally.
Coons wynellThe use of standard section connecting bolts should comply with the user manual and specification requirements.
The counterweight guide rail should meet the specification requirements.
Pipeline rupture valve: When the hydraulic system pipeline ruptures and the car stalls and descends，Azzo Nashville， it can automatically cut off the oil circuit and stop descent
Setting requirements: The main connection methods between the wall bracket and the building include: connecting the wall bracket with the embedded parts on the wall; Fix with wall bolts; Embedded bolts; Welding with steel structures.
In addition to fixed modes， there are also types of car mounted mobile devices. As the name suggests， this type of lifting device is a combination of lifting equipment and car mounted systems. It is very flexible to move， and of course， it is better to use it. For example， there are such lifting devices in airports， and car stations or sports stadiums may also be equipped with such devices， as they can be moved， So the scope of the operation is not limited to a specific place but can be used wherever lifting operations are required. For example， when installing outdoor advertisements， some advertisements are relatively high in height. At this time， mobile lifting equipment can be used to transport billboards or staff to the designated height for work. This type of equipment can also be divided into two types based on the driving mode: hydraulic lifting and electric lifting. The so-called hydraulic lifting is the use of hydraulic oil to drive and reach a specified height. The electric mode is driven by a motor or teeth to lift to a certain height. However， currently， hydraulic lifting platforms are more widely used.
Low 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， stability， etc.， and the production should meet the design requirements.
Convenient and efficientModel Example: Hanging Cage Specification: LABSC/TDx Type I: ~ Type II: ~ Type V: ~ Technical Requirements: The load-bearing capacity of the foundation should be greater than P: P=(hanging cage weight+outer cage weight+total weight of guide rail frame+counterweight+load) x. (kN).
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.
The net height of the landing door opening should not be less than m， and the difference between the net width and the outlet width of the cage door should not exceed mm. When the floor door is closed， except for the gap between the lower part of the door that should not exceed mm， the size of any through-hole and opening related to the distance between any door and adjacent moving parts， should comply with the provisions of Table of "Mechanical Safety - Safety Distance to Prevent Upper and Lower Limbs from Touching Dangerous Areas" GB-.
Braking. The brake limit switch for partial motion control of the electric hoist traction machine. Assembly that restricts the operation of the lift car when it is opened to a high or low position; If the limit switch controls the overtravel switch. When the car travels to a high or low position， it will take on the function of raising or lowering. In order to prevent the lift car from crashing or sinking， and installed in the machine room， rather than in the shaft; A buffer should be installed that can absorb the energy of the moving mechanism and reduce impact.
retailerThe list of materials for making landing doors is as follows: Table : List of materials for making landing doors. Landing doors should be installed at the entrance of each landing station， and the landing doors should function properly.
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， 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.
The net height of the landing door opening should not be less than m， and the difference between the net width and the outlet width of the cage door should not exceed mm. When the floor door is closed， except for the gap between the lower part of the door that should not exceed mm， 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 of "Mechanical Safety - Safety Distance to Prevent Upper and Lower Limbs from Touching Dangerous Areas" GB-.
Azzo The 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.
Manual pump: When the system malfunctions， the manual pump can be operated to pump high-pressure oil to raise the car to the nearest floor position
