Brugg Lifting

Elevator ropes from Brugg Lifting. Tips for rope handling.

anwendungshinweise

This section provides important information and tips regarding the properties of ropes and the handling of ropes. If required, we will provide you with additional information and will of course be available to us to answer any questions.


Transport  


Use only appropriate lifting devices when handling reels.



Avoid direct contact with forks or other hard surfaces.


Use slings or other appropriate lifting devices when handling coils.

Storage  


Ropes should be stored clean, dry, shaded from insolation, if possible on pallets.


Store ropes in a clean and dry place off the ground. Protect against moisture and any mechanical damage. Keep out of
direct sunlight.

Rewinding


Avoid kinks when rewinding.




Try to keep the rope away from the ground. Remember to maintain a certain rope tension.

Uncoiling 


When uncoiling the rope, be careful not to get any loops.


Do not uncoil the rope on a dusty, dirty surface.


It is best to uncoil the rope from the coil. In order to make the turning of the coil easier, we recommend using a suitable device as axis.

Installation 


Do not drag ropes over sharp edges. This might damage the rope or induce undesired torque build-up.


Use a rotating support during installation.

Lubrication 


All elevator ropes of Brugg Wire Rope Inc. are lubricated during the production process. Since it is not under our influence, how long the ropes are stored until the mounting, we recommend checking the elevator ropes directly after their installation for sufficient lubrication and, if needed, lubricating again. The further lubrication of the ropes should be effected as required. The ropes must however never be used in an unlubricated state. A sufficient amount of lubricant has to be on the rope, it must not drip however from the rope during the ride of the lift.

We recommend the use of the special regreasing agent of Brugg or an equal lubricant. If you relubricate in time, you can increase the service life of the rope.

When is lubrication needed?
If there are no traces of lubricant left on your fingers when you touch the rope, you need to relubricate.

How much lubrication is needed?
0,4 litres of lubricant per centimetre wire rope diameter and 100 metres rope (relating to Brugg relubricant).

Principles for relubrication
You should relubricate your wire ropes often, but sparingly. The lubricant has to be evenly distributed on the complete rope surface. The relubrication should be only done on clean rope (humidity, dust, etc.).

Demands on the relubricant
The relubricant has to be mixable with the mineral original lubricant. It has be able to penetrate well, the coefficient of friction µ ≥ 0,09 (-) (material pair steel  /cast iron) has to be reached, so that the degree of traction is preserved.

Groove shape

Rillenzustand

The correct geometrical form of the traction sheave grooves is important for the rope service life. During the service life of the rope the traction sheave grooves are subject to wear caused by friction stress (slippage and slippage due to stretch). Due to the stress (traction-, bending-, transverse- and friction stress) during operation, the rope diameters and the groove shape change (See picture on the left).

The rope diameter of new ropes is usually bigger and may not fit into existing lower, run in and tighter traction sheave grooves. When using new ropes the groove type therefore has to be checked (radius gauge). If the traction sheaves deviate strongly from the ideal
condition, they have to be replaced or, if possible, re-turned.

Rope alignment

Make sure that the rope is not twisted. You can check this easily with the help of the i-LINE.

Admissible rotations depending on the installation height

Rope tension

Seilspannung

Check the rope tension immediately after mounting with a suitable device, for example the RPM BRUGG. Make sure that all ropes in the rope group are evenly tensioned. Repeat the rope tension check 3 months after the commissioning of the installation and later on in regular intervals.

Anti rotation device 

Verdrehversicherung
Verdrehversicherung

Ropes must be secured against rotation immediately after completion of installation, before operating the elevator.

Discard criteria 

Ablegereife

Rope discard criteria according to DIN 15020

The following admissible discard wire break numbers for our elevator ropes result from these

Elevator ropes are not fatigue endurable and therefore have to be checked regularly by specialized staff according to the stress. The checking intervals have to be chosen so that damages can be detected in time.

The determination of discard criteria and the monitoring of the elevator ropes in use are in accordance with ISO 4344 / DIN 15020, Blatt 2. Decisive for the determination of the discard criteria according to the type and number of wire breaks is the number of load bearing wires in the outer strands. It is recommended to document the regularly carried out checks. Also part of the rope check is the checking of the rope end terminations.

Mounting and securing of the dead end of rope at wedge sockets

2 wire rope clamp with a u-shaped clamp (EN 13411-5)
3 soft wire
X ≈ 0,75 L

Inspection of installation
Rope end connections with wedge sockets should be checked during the inspection of the rope. Special attention should be paid to:

  • damages on the rope, such as broken wires.
  • deformations of the rope on the spot where it comes out of the housing.
  • the state of the wedge socket housing, especially if long extension of the wedge is noticed. The plates of the housing have to be
    checked for possible deformations, cracks or other faults.
  • the secure position and the tight fit of the wedge.
  • the state of the bolt including possibly existing threads.
  • the presence of the splint in the right position; the splint has to be bent.

 


Seilschossmontage

1 according to 13411-7
2 wire rope clamp with a u-shaped clamp (EN 13411-5)
X ≈ 0,4 L

The housing and the wedge as well as the part of the rope that lies in the wedge socket have to be checked every time the wedge socket is dissembled. Damaged parts have to be replaced.

A - The measurement X denotes the distance from the clamp to the proximal part of the housing. X should be about 75% of the total length of the wedge. This way it is avoided that the rope is deformed, if X is too small or that the wedge can fall out of the housing, because X is too big and the rope therefore is relaxed. (See picture right next).

B - The distance X of the wedge to the proximal part of the housing should be about 40% of the total length of the wedge. This way it is avoided that the rope is deformed, because the distance is too small or that the wedge can fall out of the housing, because the distance is too big and the rope therefore is relaxed.
