2. What are Crane Cables made of?

Crane cable are made of the following:

  • Wires

Steel wires in crane cables consists of non-alloy carbon steel with carbon content ranging between 0.4 to 0.95%.

This enables it to have very high strength that can run over small diameter sheaves and support large tensile forces.

  • Strands

It consists of wires on different layers crossing each other with equal lay lengths and parallel superimposed layers.

  • Spiral Ropes

These are round strand assemblies of layers of wires helically laid over a center with other layers in the opposite direction.

  • Stranded Ropes.

It consists of several strands helically laid around a core in one or more layers.

The core can either be fiber core, wire strand core, and independent wire rope.

3. What Type of Wire Rope is used on Cranes?

Cranes use different types of wire ropes such as:

  • High Performance Wire Ropes

This is a steel wire rope which transmits tensile strength with a basic design that allows continuous change in pull direction.

  • Rotation Resistant Ropes

This type of rope falls under three different classes including spin resistance, rotation resistance and non-rotating wire ropes.

These ropes have the outer layer twisted in the opposite direction of the inner layers.

Spin resistant ropes and rotation resistant ropes have a single inner layer rotating on a different direction.

Non-rotating wire ropes have several layers rotating in different directions thus cancelling the rotation altogether.

  • Construct 6

These are high strength swage compacted ropes with 6 strands perfect for crush resistant applications and multilayer winding systems.

  • Compac 18

This type of wire rope is recommended for both single part applications and multipart loads where you need medium rational stability.

  • Compac 35

It is perfect for auxiliary and main hoist lines for all construction tower cranes that require high strength rotation resistance.

4. How does Wire Rope and Crane Cable Compare?

You can use the term wire rope and cable interchangeably.

However, wire ropes have rope diameters that are greater than 3/8 inches.

Cables or cords are the wire ropes that have rope diameters smaller than 3/8 inches.

In case you come across two or more wire concentrically laid then it becomes a strand.

5. What is the difference between Crane Cable and a Festoon Cable?

Festoon Cable

Festoon cable

Festoon cables are portable cords for special power and control applications in festoon cable systems and cranes.

You will use the festoon cable in applications where space is at premium or where you require premium extreme flexing.

Crane cables are a range of cables that you can use in the powering and controlling of cranes and festoons.

You will use a crane cable in applications that do not involve any form of rotation and flexibility.

Such applications require high tensile strength to carry heavy loads from one place to another.

6. What does 6 by 19 and 7 by 19 mean in Wire Rope?

These are classifications of wire ropes used to determine the properties of the wire rope you choose to use.

6 by 19 is a type of wire rope that can withstand abrasion, fatigue resistance and prevents crushing on drums.

It is available in different diameters ranging from 3mm to 6 mm.

7 by 19 have diameters ranging between 3 mm to 16 mm that you can use on different applications.

Some of the applications where you can use the 7 by 19 wire rope is in pulley applications.

7. Are Crane Cables UV-Resistant?

Yes, crane cables are resistant to UV rays thus increasing the durability of the crane cables.

What’s more, crane cables are also resistant to greases and oils.

The cable carries great loads and needs protection from any form of electromagnetic interference.

8. What are Crane Cables used for?

Crane cables are usually perfect for dynamic hoisting and lifting in elevators and cranes.

Apart from that, crane cables are responsible for the transmission of mechanical power in crane applications.

This allows you to use crane cables in lifting and hoisting materials that are very heavy from one place to another.

9. What are the Benefits of Crane Cables?

Some of the benefits that you will experience while using the crane cables include:

  • It reduces the weight of the products by 60 to 90% thus allowing for easier lifting of loads.
  • It improves fatigue resistance and load chart
  • It has very low cost of installation and is very easy to handle.
  • Crane cables are durable with a longer extension life.
  • The cost of maintaining crane cables are low.
  • It is resistant to corrosion thus allowing you to use it in all weather conditions.
  • Crane cables have different types of end terminations and do not have length restraints.
  • Crane cables consists of multiple strands of wires that spread the weight uniformly to allstrands.
  • Should one wire break in the operation process, crane cableshave enough strength to complete the operation in progress.

10. What is the Structure of Crane Cables?

The structure of the crane cable consists of four basic components which include:

  • Metal Wires

These are the smallest components of the crane cable that that make up the individual strands of the rope.

The metal wires come from different materials such as steel, stainless steel, iron, bronze, and Monel.

They are available in grades depending on strength, fatigue resistance, resistance to wear, curve of wire rope and corrosion resistance.

  • Multi-Wire Stands

It consists of two or more wires twisted and arranged in specific arrangement order.

The individual strands then assume a helical pattern around the core of crane cables.

Strands with large wire diameters are resistant to abrasion while the strands with smaller diameters are more flexible.

  • Steel or Fiber Core

This part of the cable runs through the center thus supporting the strand and assisting in maintenance of relative position.

It will maintain the position of the crane cable under extreme conditions such as bending and loading stresses.

The care comes from different materials such as steel and synthetic fiber.

  • Lubrication

Lubes are applied in the manufacturing process and they penetrate through the other parts to the core.

They are important for:

i. Reduction of friction as individual strands move over one another.

ii. Provision of corrosion protection and lubrication of the outside surfaces, inside wires as well as the core.

11. What are the Characteristics of Crane Cables?

The characteristics of crane cables that you need to look at before purchasing include:

  • Strength

This is the minimum breaking force of a crane cable which determines the amount of weight it can withstand without breaking.

You should consider a crane cable with the strength that can withstand the tension from your applications.

  • Reserve Strength

This is the relationship between the strength of all the wires in the outer strand and those with the wires removed.

It is an important characteristic in the inspection, evaluation and selection of a crane cable for different applications.

  • Resistance to Deformation and Metal Loss

This relates to the type of material that the manufacturer uses in making crane cables.

The material should be strong enough to resist metal loss through certain factors such as corrosion.

  • Crushing Resistance

Crushing refers the effect of external pressure on the crane cable which can distort the cross sectional shape.

You should consider a crane cable with the ability to resist or withstand external forces thus increasing the efficacy.

  • Fatigue resistance

This is the fatigue of the metal which makes up the ropes.

You should go for a crane cable with the ability to bend repeatedly under stress.

  • Bend-ability

This is the ability of the rope to form an arc easily under minimal pressure.

Bendability is, therefore, affected by the following factors:

i. Diameters of individual wires which make up the crane cable

ii. Strand and Cable construction

iii. Metal composition of the wires and surface finish

iv. Type of rope core within a crane cable

  • Stability

This refers to the handling and working characteristics of a crane cable which allows you smooth and easy operations.

The more the stability of a crane cable, the easier the working conditions.

12. Crane Cables Should Conform to which Quality Standards?

Crane cables should conform to the ISO 4309:2011 requirements and CE standards.

13. What is a composite crane cable?

Composite crane cables are cable alternatives to steel crane cables with a composite of materials making them lighter than steel.

Apart from that, composite crane cables increase fatigue resistance, reduce cost of maintenance, and extend life of cables.

14. What is an Elevator Crane Cable?

Elevator crane cables are hoist and lift cables that you can use in elevators moving through different floors of a building.

They assist in effective and smooth lifting of elevators with very strong and durable wire ropes.

You can as well use it in manufacturing companies, harbors and offshore platforms.

15. How does Sensor Crane Cable and Pendant & Reel Cable Compare?

Sensor crane cables are types of crane cables with sensors that assist in the measurement, control and automation of cables.

It is capable of attaining the exact and accurate instructions from the control panel.

On the other hand, pendant and reel cables are special for continuous flexing applications in harsh conditions.

Pendant and reel cable cranes can withstand abrasion, flames, moisture, chemicals, temperature and impact extremes.
