SwarthElectricThe gantry elevator is used in the door legs of large gantry cranes to transport workers and maintenance components inside the gantry crane
The elevator suddenly descends to the bottom floor and resumes normal operation: After the elevator is powered off and reconnected, the leveling reference position needs to be re determined.
Swarth.The effective support width of the upper and lower support beams should be greater than the width of the escalator truss, and there should be embedded steel plates.
Aircraft weighing tens or hundreds of tons in the elevator hangar are vertically lifted onto the airport runway
.The elevator suddenly descends to the bottom floor and resumes normal operation: After the elevator is powered off and reconnected, the leveling reference position needs to be re determined.
The difference between home elevators and ordinary public elevators is that the focus of home elevators and ordinary public elevators is different, the load capacity of home elevators does not exceed 400kg,SwarthFully automatic hydraulic tipping machine hopper, which is much lower than that of ordinary public elevators. Home elevators do not need to consider the issue of passenger flow, and the lifting speed is slower, ensuring safety. The lifting speed is generally between 0.3 to 0.4m/s, and running smoothly.
The braking system of the elevator is usually closed, which means it is in the braking state when there is no power, and only when it needs to be turned on, will the power turn on the brakes. So as soon as there was a power outage, the brakes closed and the elevator was braked in mid air. When the elevator descends abnormally, it is cut off
These phenomena are not elevator malfunctions. When the elevator is fully loaded, the elevator does not stop: to avoid overloading, the elevator car no longer responds to the next station's outbound call.
It is not recommended to force doors or self rescue from car roof safety windows. Because climbing out of the car is not equivalent to rescue, most passengers are unfamiliar with the elevator shaft and elevator structure, and blind self rescue often poses greater danger.
When wearing high heels be careful not to step on the gap between the pedals, as not wearing shoes is more likely to be pinched by the toothed plate.
Quality inspection report.When passengers are riding on the escalator, they may lose their balance and fall due to leaning against the skirt board on the side of the escalator, but their feet move with the steps. Especially when carrying a lot of packages while taking the elevator, it is more likely to fall on the escalator due to the inability to hold the handrail properly. So, when riding on the escalator, and do not lean against the skirt board on the side of the escalator.
Overloaded elevators do not operate: The load of elevators is limited, and if they are overweight, they will alarm and generally cannot be started. Most passengers can also voluntarily exit.
The elevator suddenly opens the door and does not move after leveling, but automatically resumes operation after a few minutes: The elevator (escalator) has been running for too long, and the motor overheats. To prevent burning out, the motor cools down and automatically resumes operation.
2. Different types of civil engineering traction elevators screw elevators, and hydraulic elevators have different requirements for civil engineering. Common traction elevators require a certain amount of hoistway space, which can be made of concrete, steel structure hoistways, and glass curtain walls to create sightseeing elevators; The depth of the pit should be at least 50cm or more; Additionally, there are certain requirements for the height of the top floor.
discount.Elevators are used to transport firefighters, passengers,SwarthResidential use of indoor elevators in duplex buildings, and fire-fighting equipment in the event of a fire. They are used to transport frozen goods in large cold storage or refrigeration workshops. However, they need to meet the requirements of sealing the door leaves and guide rails at the moving parts. Professional household elevators, villa household elevators, household elevator manufacturers, and small household elevators have stable safe, reliable, and maintenance free performance, and their technical level has reached the domestic level, Meet the advanced level of international similar products and immersion requirements
For escalators that require intermediate support, it is necessary to determine whether the site has the conditions for adding support, as well as the range of support that can be added, the height and load size of the equipment and support platform, and other parameters.
The difference between home elevators and ordinary public elevators is that the focus of home elevators and ordinary public elevators is different, the load capacity of home elevators does not exceed 400kg, which is much lower than that of ordinary public elevators. Home elevators do not need to consider the issue of passenger flow, and the lifting speed is slower, ensuring safety. The lifting speed is generally between 0.3 to 0.4m/s and running smoothly.
Swarth.Elevator Tip 1: Why elevators can trap people? Every elevator door on each floor has a safety switch,SwarthHousehold villa elevator manufacturer, which can trigger the elevator to shut down in case of any abnormality. The elevator getting stuck is actually when the system detects an abnormal signal and triggers a protective device, like braking to stop.
The braking system of the elevator is usually closed, which means it is in the braking state when there is no power, and only when it needs to be turned on, will the power turn on the brakes. So as soon as there was a power outage, the brakes closed and the elevator was braked in mid air. When the elevator descends abnormally, it is cut off
Elevator does not close the door or repeatedly opens and closes the door: there are debris blocking the light curtain or door contact plate at the entrance or sill.
