Elevator accessories – selection of steel rope

In order to be safe, the hoisting steel rope of the elevator is used with special or no. 1 steel wire, and its steel wire diameter is limited to between 0.3 and 1.3mm. The hoisting rope of the elevator is seru (X type) and warrington (W type). At present, the domestic elevator generally uses the silu-style 8 or 6 steel rope hauling steel rope, among which 8X(19) has more applications.

Elevator parts – selection of steel rope

1. Example of steel rope mark identification.

1000kg of passenger elevator to the rated load, for example, SCH elevator traction rope with 8 X (19) – 16-140 right hand in, eight for the line number of shares, X is west lu type, (19) for each strand of wire number, 16 for SCH elevator traction rope nominal diameter (mm), and 140 for SCH elevator traction rope tensile strength (KGF/was), the right to pay for steel wire strand and strand in line right direction twist system. The domestic SCH elevator traction steel rope is right handed.

2. Steel rope core

SCH elevator traction steel rope was used for the oiled fiber rope, rope support and fixed rope stock position so as to improve the contact between the steel rope, slow down the impact load, fuel storage pool role for SCH elevator traction steel rope of lubrication oil source for a long time, make good lubrication performance of the steel wire.

3. The structure and characteristics of the siu-type (X) SCH elevator traction steel rope.

SCH elevator traction rope in strands of the cross section of a share to 1 + 9 + 9, namely core plus the first layer and the second layer, a total of 19 roots of steel wire: center wire 1 root, φ1.2 mm, inner layer steel wire 9 root, φ0.6 mm, outer wire 9 root φ1.05 mm. The outer diameter is larger than the inner diameter, so it is also called the outer rough elevator to drag the steel rope. It is characterized by the same number of steel lines in the inner and outer layers of each share, but the diameter is different, the outer layer is embedded in the inner cavity of the inner layer, the twisting distance of the multi-layer steel wire is equal, the structure is tight and strong, and it is not easy to open the volume. The outer thick steel wire increases the wear resistance; the inner layer fine steel wire enhances softness, which is advantageous to the sliding of the bending moment, thus improving the flexibility and service life of the elevator traction steel rope. Between the two layers, the steel rope is in contact with the steel rope, and the fatigue resistance of the steel rope is good. The resistance of the steel wire is good, the contact area is increased and the contact stress is reduced.

Three tips warning for Elevator

1. Do not allow to grill elevator door by hands in any condition when it is running.

More than 70 per cent of elevator accidents occur on door system. Why we say that? Anyone who knows the structure of elevator knows that it would be like a trap in front of your feet. There is a risk of shearing, squeezing, and hanging from the inside. So, when you take the elevator, you must see it clearly and then step back, wait for the elevator stop, and then leave the door open.Continue reading→

How long does the elevator service life?

How long does the elevator service life?

Generally speaking, the life of the elevator that the manufacturer promises is 20 years.
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.
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.

(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.
