The requirement for the shaft is that it should not be plastered, which is beneficial for reducing noise, but there should be no protruding foreign objects.Measure the length, width, and depth of the pit (if any), and observe whether there are grooves and embedded parts at the support beam.Mentougou,. Different types of civil engineering traction elevators, screw elevators, steel structure hoistways, and glass curtain walls to create sightseeing elevators; The depth of the pit should be at least cm or more; Additionally, there are certain requirements for the height of the top floor.Measurement of elevator and escalator shafts (III)Ifo,MentougouAluminum alloy high-altitude lifting platform, the plane size of the shaft can be measured in the machine room 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, 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, users should be reminded to provide them to the elevator after the old elevator or notify the elevator to take measurements before the new elevator is put into operation.　　“& rdquo; Elevator shaft: The design conditions are provided by the user to the architectural design department. The architectural design department analyzes whether the on-site pit depth, top floor height, reaction force, etc. can meet the installation requirements of the elevator, as well as which building structures are needed (such as smashing stairs or floors), and develops a renovation construction plan. If it is indeed necessary to change the elevator structure due to civil engineering conditions (such as car size, door opening width, etc.), then consider the non-standard design of the elevator.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.

Measure the length, width, and depth of the pit (if any),MentougouBarrier free vertical lifting platform, and observe whether there are grooves and embedded parts at the support beam.When encountering abnormal elevator operation, immediately close the door and return to the first floor station, and automatically open the elevator door.manufacturer,In the event of a fire, when instructed by the fire center or the dedicated operation button of the first floor firefighter to enter the firefighting state, the elevator should immediately stop on the floor without opening the door, return to the first floor station, and automatically open the elevator door if it is in the upward direction.Measure the length, width, and depth of the pit (if any) and observe whether there are grooves and embedded parts at the support beam.Maintenance of elevator hall doors and car doors. Elevator malfunctions usually occur on the elevator hall and car doors, so attention should be paid to the maintenance of the hall and car doors. One is to refuel the fuel on the upper sill of the door and keep it in good condition, so that the elevator will not make unpleasant noises during operation and the opening of the door. Pay attention to the inspection of the safety contact plate or light curtain type contact plate switch wire of the elevator, as the frequency of opening and closing the door in the elevator is high, which can cause damage to the switch wire. This requires maintenance personnel to inspect it every time they work and replace it in advance to avoid users having doubts about the quality of the elevator product due to door issues.

The call button on each floor is no longer working, and the call is cut off.Installation works,When the normal power supply is cut off, the lighting inside the non fire elevator has no power,MentougouMobile reclaimer, while there is still lighting inside the fire elevator.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, cut off the power and the elevatorThe basic content of escalator shaft measurement is to measure the lifting height. The same as measuring the height of a straight ladder, strictly speaking, the lifting height of a ladder is the vertical distance between the finished ground at the upper and lower support beams. When using the suspension line method to measure, attention should be paid to whether there is a drop between the positioning point of the line drop and the decoration surface of the lower support beam of the ladder.Mentougou,The safety monitoring machine room environment screen cabinet main power switch traction wheel speed limiter shaft and pit guide rail layer door and car counterweight should be reliably fixed with pressure plates to prevent loosening.Attention: The elevator consists of two main parts: mechanical and electrical. If the elevator is not maintained on a daily basis, its safety cannot be guaranteed. If the elevator needs to be refueled without refueling, it will cause wear and tear on the mechanical components of the elevator, greatly shortening its service life and preventing normal use of the elevator.The front room of the fire elevator is equipped with indoor fire hydrants.
