Technical conditions for main parts scrapping of elevators

  1. Three core components , the host, door machine, control drive system (that is, the panel in the control cabinet and converter) steel wire rope, long service life and can reduce maintenance costs, speed limiter, buffers, safety gear, the three is the most key components in the elevator safety, more than four pieces can consider to import
  2. Four Spaces: part of the machine room, well road and pit, car part, floor part.
    Eight systems: traction system, guide system, cage, door system, weight balance system, electric drive system, electrical control system, safety protection system.
  3. Eight application technologies:

How long does the elevator service life?

How long does the elevator service life?

  1. Generally speaking, the life of the elevator that the manufacturer promises is 20 years.
  2. so the elevator service life as normal, generally use ten to fifteen years or so, the working condition and maintenance efforts, do a repair, replacement of a batch of badly worn, obsolete, do not conform to the new rules of the components, with five to eight years, then can do it again on upgrading and replacement of a full range of security components, replace the latest host and control system, capsules and guide rail can preserve, involved in capsules showed what can change, and can continue to use about ten years, eight years later to a whole new ladder.
    The elevator service life can be used for twenty-five to thirty years if under good condition.If you are worried about the supply of Elevator Parts or Escalator Parts , you can contact us.
  3. Therefore, three years for new, three years for old ,and three years for mended, The elevator service life can be used for twenty-five to thirty years if under good condition. If you are worried about the supply of Elevator Parts or Escalator Parts , you can contact us.

 

 24 Factors May Cause an Elevator Failure in 2018

Every elevator part is very important. Any failure of an elevator part will cause an elevator accident. Therefore, it is very important to ensure the safety of the elevator.

Every elevator part is very important. Any failure of an elevator part will cause an elevator accident. Therefore, it is very important to ensure the safety of the elevator.

(1) The defects of the motor will affect the safe operation of the whole drive system, and it is easy to have an unsafe impact on passengers.

(2) Severe wear or peeling of the gear (worm gear pair) will cause the elevator to run out of control due to the failure of the transmission, which may cause damage to the personnel.

(3) The brake, brake springs, brake arm, failure will cause brake failure, cause the car run out of control, thus, header, Dun bottom accident caused casualties and severe damage to equipment.

(4) The severe wear and hardness difference between the grooves and the grooves of the traction wheel will reduce the traction of the elevator, which can cause the elevator to run out of control and cause damage to passengers.

(5) The failure of the anti-rope wheel, the rewinding wheel and the guide wheel can easily cause the elevator to run out of control and cause damage to the passengers.

(6) The defects of the steel wire rope and the rope head are easy to cause the steel wire rope to break or slip, the cage fall, and cause the damage of equipment and buildings, and the serious accident of casualties.Continue reading

7 Factors May Cause Escalator Failure in 2018

7 Factors May Cause Escalator Failure in 2018
1. Cascade failure
The stairway is a standing place for passengers to take a ladder and a continuous running part. Due to environmental conditions, human factors, such as the object itself causes, cascade failure mainly has the following aspects: tooth broken, pedal stent fracture spindle hole, stent fracture, the main wheel come unglued.
2. Failure of the drag chain.
Drag chain is one of the largest stress escalator parts, due to the long running, accordingly more serious wear and tear, and the main fault include lubrication system fault, drag chain serious wear and tear, drag chain elongation.
3. Failure of the driving device.
The main fault of the driving device includes the abnormal sound of the driving device, the temperature rise of the driving device is too fast and too high. The reasons for failure of the driving device are as follows:Continue reading

Benefits and Drawbacks of Machine Room-Less (MRL) Elevators and Machine Room (MR) Elevator

The machine room-less (MRL) elevator is relative to the machine room (MR) elevator, which is using modern production technology to miniaturize the equipment of machine room as far as possible while maintaining the original performance, move the control cabinets, traction machine, governor, and other parts to top or sides of elevator hoistway, thus the traditional machine room was cancelled, in order to meet the customer’s special requirements for height and roof.

control cabinets, elevator hoistway, governor, machine room elevator, machine room less elevator benefits, machine room less elevator disadvantages, machine room less elevator drawbacks, machine room less elevator drawings, machine room-less elevator, machine room-less elevator cost, machine room-less elevator price, MR elevator, MRL elevator, traction machineContinue reading
