HoustonFully sThe safety distance between the outer edge of the upper part of the landing door and the moving parts of the electric elevator during normal operation should not be less than 0.75m; If the rated speed is not greater than 0.7m/s, the safety distance can be 0.40m.
The entrance of each landing platform must be equipped with a landing door, which must open towards the landing platform side, effective protective measures should be taken.
.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.
Double layer steel mesh: The diameter of the steel bars is 12mm, with a spacing of 200mm.
The safety distance between the outer edge of the upper part of the landing door and the moving parts of the electric elevator during normal operation should not be less than 0.75m; If the rated speed is not greater than 0.7m/s, the safety distance can be 0.40m.
The verticality of the guide rail frame should meet the requirements of the specifications.
8m； When the lifting speed is greater than 0.8m/s, after the upper limit switch is triggered by the hanging cage, the upper small safety distance L should meet the following requirements: L=8+0.1V2, where L is the upper safety distance; V: Increase speed
When the landing door is closed, the full width of the lifting passage opening should be covered.
Click to view.Later, when there is a major malfunction of the lifting platform, it should be repaired by professional personnel as soon as possible. After the malfunction occurs, it should not be used again to avoid accidents,HoustonElectric guide rail elevator, personnel and property losses.
The net height of the landing door opening should not be less than 8m,HoustonStage electric elevator, 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.
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.
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, stage equipment should be dismantled with over travel switches that can cut off power and cannot be automatically reset 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.
Standard requirements.The scissor type electric elevator is a widely used high-altitude operation special equipment. Its scissor mechanical structure ensures high stability of the lifting platform, wide working platform and high bearing capacity,HoustonElectric elevator cargo elevator, making the high-altitude operation range wider and suitable for multiple people to work simultaneously. It makes high-altitude operation more efficient and safer
The cleanliness of the hydraulic station is an important aspect of the electric elevator hydraulic station, so it should not be taken lightly. And from a professional perspective, there are relevant rules and requirements that should be referred to in the specification manual, the manual pump can be operated to pump high-pressure oil to raise the car to the nearest floor position
