Does the specified length refer purely to the steel cable or is the complete length measured?
The specified length refers to the actual usable length incl. swaged loops, thimbles or terminals (and ¾ opened tensioners, if any). Under the technical details on each product detail page you will find a representation for the length specification of the wire rope.
What does the length range mean?
In the case of wire ropes with individual length production, the appropriate length range must first be selected and then the exact desired length must be entered in the field provided. The length range is necessary to determine the price. For the underlying dimensions, please refer to the technical details on each product detail page.
May stainless steel accessories be combined with galvanized wire ropes or galvanized accessories with stainless steel ropes? May stainless steel ropes, for example, be crimped with aluminum crimping clamps?
In principle, we advise against the use of different metals, due to different electrochemical properties. In the worst case, contact corrosion can cause a substance to dissolve.
What is the elongation of wire ropes?
The elongation at break of steel wire ropes is only approx. 1.5 - 1.8% elongation. The modulus of elasticity for wire & steel ropes cannot be determined without error. The modulus of elasticity differs greatly for wire ropes because the internal friction of the individual wires is very different.
What is the minimum bending radius of wire & steel ropes?
For the smallest permissible bending radius of a steel wire rope, please multiply the diameter of the steel wire rope by 20. For example, a 3mm wire rope has a bending radius of at least 60mm.
What is the difference between flexible and stiff wire ropes?
Wire ropes with the 1x19 construction are considered 'stiff' and less flexible due to the low number of individual wires. The 7x7 and 7x19 constructions, on the other hand, offer high flexibility due to the high number of individual wires. Due to a higher material density, stiff wire ropes generally have a higher breaking load than flexible wire ropes of the same rope thickness. Stiff wire ropes can be used for straight guy wires without deflections (for example, for shrouds on a sailboat). For a climbing aid, flexible wire rope is more suitable, as the rope provides more surface area for the plants.
The special length is specified as 0.30m - 1.00m, what length is now supplied? I need 0.70m.
Please first select the length range in which your desired length is located (0.30m - 1.00m). Then enter your exact desired length (0.70m) in the desired size field.
Does the specified payload apply only to the wire rope or also include the swaged terminals, thimbles or loops?
The minimum breaking load or working load refers to the complete rope connection, since in all test trials it was always the wire rope that broke. Alternatively, a lower value is given (for example, for wire ropes with turnbuckle DIN 1480 hook / eye).
What is the diameter of the wire rope's ferrule?
The diameter of the crimping clamp has the size of twice the rope diameter in each case.
Is it possible in principle to order total lengths that are less than 0.30m?
Yes, depending on the rope thickness, rope length less than 0.30m can also be made. You are welcome to place the order for this, if it does not fit, we would contact you again.
Do open wire ends of wire ropes need to be fixed so that they do not drip open?
Yes, the wire rope end should be protected from splicing with the help of an end sleeve (https://www.steelropes24.com/wire-rope-end-sleeves-black).
What does annealing separation mean?
In the process of annealing, the individual wires are desoldered from the open end of a steel cable to prevent them from splicing.
Are wire ropes magnetic?
Yes, magnets adhere to the wire rope due to the iron content in the rope.
How can the minimum breaking force of Newton/mm² of the wire ropes be converted into maximum weight force that the wire rope can safely withstand?
To calculate the minimum breaking force, divide the value of the minimum breaking force from the table by the earth's gravitational force (9.81). Example 3mm (6x19) wire rope galvanized: 5,420 N : 9.81 = 552.50kg. Please note that this is the actual breaking force. Please add at least a 3-5 times safety factor for your application. Example 3mm 6x19: 552.50kg : 5 = 100kg.
