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.
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.
Dortmund.b. When the old elevator cannot start: due to the inability to enter the shaft, limited data can only be obtained from outside the shaft to determine whether it is non-standard (if there is a high platform in the machine room, the plane size of the shaft can be measured in the machine room, but it is not accurate enough) for elevator quotation negotiation reference. In this case, the signing of the contract should state that the shaft rectification and costs are the responsibility of the user. For uncertain shaft structures and dimensions, screw elevators, and hydraulic elevators have different requirements for civil engineering. Common traction elevators require a certain amount of hoistway space,DortmundElevating platform stage, 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.
.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.
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.
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, the brakes closed and the elevator was braked in mid air. When the elevator descends abnormally, it is cut off
Will the elevator quickly fall during a power outage& mdash;& mdash; Some movies and TV dramas often mislead the public into thinking that if the elevator loses its power, it will lose control and engage in falling movements.
Measurement of elevator and escalator shafts (III)
Household elevators have gradually become an essential vertical transportation tool for modern single family, duplex, multi story, villa and other residential buildings, practical and convenient, and even a beautiful scenery in the home.
How many?.There are many similar situations in daily life,DortmundAluminum alloy mobile lifting platform, causing the circuit to disconnect and forcing the elevator to stop, resulting in people being trapped. For example, if the elevator frequently enters and exits during decoration and falls into the crack of the door,DortmundVertical obstacle free lifting platform, the elevator hall door may not be tightly closed, and after several consecutive doors are opened and closed, the elevator will stop. Professional quality assurance for home elevator manufacturers. Discount activities are underway, and new and old customers are welcome to come for consultation
The seat elevator person sits on a chair driven by an electric motor, and the button on the chair handle causes the power drive device at the bottom of the chair to drive the person chair up and down along the guide rail of the staircase railing
As elevator people, let's talk about elevator and elevator safety knowledge: The elevators we currently use include box type passenger elevators, escalators, and dedicated cargo elevators. Dedicated cargo elevators are installed due to special needs, and we don't use many of them. Now, let's take a look at the safety knowledge of box type passenger elevators and escalators: When we take escalators, Be sure to follow the safety instructions when riding on the elevator. Do not crowd or play around hold onto the elevator firmly, fasten your shoelaces, and avoid getting them caught up.
Elevator Tip 1: Why elevators can trap people? Every elevator door on each floor has a safety switch, 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.
Quality improvement.When accidentally trapped in an elevator, one should remain calm, press the alarm bell inside the elevator, and call the elevator emergency rescue phone or community property phone for help. Do not open doors or mess with buttons and patiently wait for rescue.
No oil pollution. Due to the absence of tooth profile wear issues and the need for regular oil replacement, it has a long service life, reduces oil pollution, and only when it needs to be turned on which means it is in the braking state when there is no power, 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
Dortmund.Household elevators must be regularly maintained to confirm their safety and whether they can continue to operate, while also repairing any faults and hidden dangers found.
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.
The gantry elevator is used in the door legs of large gantry cranes to transport workers and maintenance components inside the gantry crane
