Steel wire ropes
The firm LANA VAMBERK manufactures and supplies steel wire ropes, with applications in various branches of industry.
Our quality system conforms to ISO 9001:2001, confirmed by repeated audit by TUV International.
Production program of the firm consists of the following steel wire ropes constructions:
- STANDARD
- SEAL
- FILLER
- WARRINGTON
- SEALWARRINGTON
- HERCULES
- STABIL
- SINGLE-STRAND
These designs are manufactured according to EN CSN 12385. At the customer´s request we can produce special designs, using our skill and experience, according to our internal standard PN 95-02.
Standard ropes are supplied lubricated. If dry (not lubricated) rope is required this must be specified on the order. We mainly use wire grade 1770 MPa. If there is a special requirement for another grade, this must be stated on the order as well.
In your orders should be
- Description of the rope
- Required delivery date

| 6x19M | construction of the rope – six strand cross laid rope (see table 2) |
| IWRC | Core – independent wire rope core (see table 3) |
| 1770 | Rope grade –1770 Mpa |
| B | Wire surface – galvanized, (see table 4) |
| sZ | lay direction and type - ordinary right lay (see table 5) |
| preformed | Method of residual stress elimination |
| reel/coil | method of packing |
| dry/lubricated | lubrication |

Table 5 – Lay directions and types
| Code | Style of lay* | Lay direction |
|---|---|---|
| sZ | Ordinary lay | Right lay |
| zS | Ordinary lay | Left lay |
| zZ | Lang lay | Right lay |
| sS | Lang lay | Left lay |
| aZ | Alternate lay | Right lay |
| aS | Alternate lay | Left lay |
* first letter means direction of lay in strands (s/z), second letter (S/Z) direction of lay in ropes.
Tolerances of manufactured ropes:
| Diameter | + 5 % | |
|---|---|---|
| Rope weight | + 5 % | |
| Rope length | till 400 m | 0% till + 5% |
| More than 400 m till 1000 m | 0 m till + 20 m | |
| More than 1000 m | 0% till + 2 % | |
According to the Standard, minimum breaking force is now specified in kN and must be calculated according to following formula:
where
| d | Is nominal diameter of the rope in mm |
|---|---|
| Rr | Rope grade in N/mm2 |
| K1 | Minimum breaking force factor is given in appropriate part of standard |
Nominal rope length mass in kg/100m, is calculated according to the formula
M=W1d2
where W1 is rope length mass factor
