Products Description
Crane cable is a type of cable specifically designed for mobile equipment such as cranes and cranes, used for power transmission and signal control. Usually composed of conductors, insulation layers, sheaths, shielding layers, etc. The conductor is the core part of the cable, responsible for transmitting electrical energy and signals; The insulation layer is wrapped around the outside of the conductor, playing a role in electrical isolation; The sheath is located on the outermost layer to protect the cable. Some crane cables also have self supporting steel wires to improve their tensile strength and stability.
It is divided into steel wire rope cables and flexible cables. Steel wire rope cables are composed of steel wire ropes and conductors. Steel wire ropes play a role in supporting and protecting the cables, while conductors transmit electrical energy signals. Flexible cables have flexibility and are suitable for situations that require frequent bending and movement.
The conductor material usually uses precision twisted oxygen free bare copper wire, which complies with GB/T3956 Part 5 and IEC228 standards. The insulation and sheath materials use special mixed PVC or nitrile composite to improve the flexibility, corrosion resistance, and cold resistance of the cable. The rated voltage is usually 450/750 V, and the operating temperature range is usually between -15 ℃ and 70 ℃.
The standard flame retardant and fire resistance test is carried out in accordance with GB12666-90 requirements, and some products also comply with standards such as GB/T 5023.5-2008 and JB/T 8734-2012.
Purpose and characteristics
Suitable for power connection and control signal lighting of various mobile power devices in industries such as lifting, transportation, machinery, electrical, mining, etc. with working voltage below 450/750V level and ambient temperature of -40~70 ℃.
It has the characteristics of bending resistance, high temperature resistance, self bearing steel wire, and tensile resistance. The cable has good flexibility and a long service life.
Soft structure, easy laying, stable electrical performance under high temperature (cold) environment, outstanding anti-aging performance.
Application field
Widely used in industries such as metallurgy, power, petrochemicals, electronics, and automotive manufacturing, especially in situations where frequent movement and bending are required.

FAQ
Q1:What is the overhead crane cable?
A1: Crane lifting cable is a type of cable specifically used to connect the crane host and power supply. As one of the core components of the crane, it is responsible for transmitting signals and electrical energy of the crane. It controls the lifting, lowering, left and right movement of the crane by connecting external controllers such as horizontal brakes, limiters, travel switches, and overload protectors, thereby completing the lifting of objects.
Q2: What are the main technical requirements for overhead crane cables?
A2: The technical requirements for overhead crane cables mainly include the following points:
Bearing capacity: It needs to withstand extremely high tensile and bending forces, and therefore, it is necessary to choose cables that can withstand high pressure.
Wear resistance: Due to the need for multiple bending and operation of cranes during operation, cables need to have good wear and tear resistance.
High temperature and low temperature resistance performance: Cranes need to withstand different temperatures in different working environments, so crane cables need to have good temperature adaptability.
Flame retardancy: The flame retardancy of crane cables is crucial for safe operation, and once the cables catch fire, it will bring great safety risks.
Durability: It is directly related to the service life of the crane, so choosing brand quality cables that have undergone strict testing and are guaranteed is a wise choice.
Q3: How to solve common problems with overhead crane cables?
A3: The following measures can be taken to solve common problems with crane cables during operation:
Proper use and maintenance: Use the crane according to the correct operating methods, regularly inspect and maintain the cables to avoid excessive wear and damage.
Select appropriate cables: Based on the actual needs and working environment of the crane, select appropriate cables to ensure that the performance and quality of the cables meet the requirements.
Timely handling of faults: Once a cable fault is found, it should be promptly addressed and repaired to avoid the fault from expanding and affecting the normal operation of the crane.
