CHARACTERISTICS AND CLASSIFICATIONS OF ELEVATOR
Liên hệ
Elevator cable is a type of cable with characteristics different from other steel cables because they are designed specifically for elevator systems . This type of cable plays an important role in lifting and lifting the entire cabin system so that the minimum traction force is suitable for the load of each type of machine for carrying people or transporting goods.
Market In Vietnam, the most commonly used steel cables in elevators are 8 × 19 (S) + FC cables with 2 diameters of 10mm and 12mm, the minimum pulling force is 48.1KN and 69.2KN respectively.
Characteristics of elevator cable loading
Elevator cable structure
Elevator elevator cable is made of 8 x19 (S) + FC and 8 × 19 (S) + IWRC. That is composed of 8 strands of cable, each strands of 19 small steel wires twisted together to form.
On the other hand, these strands are also twisted along the principle of spiraling around the core, resistant to twisting, meeting the requirements of durability and absolute safety when in use.
The main material of elevator cable download
To produce elevator cable is still high-strength carbon steel is high strength and treated before braiding the cable as mentioned above. In which the cable core is made of synthetic fiber or an independent cable and they use lubricant for the cable.
Typically, elevator cables are applied with diameters from 6mm to 38mm, depending on the structure and load of each type of elevator.
Classification lift elevator cable
Elevator load cable is considered as one of the special download cable lines. Elevator cables usually have two main production specifications: 8 × 19 (S) + FC and 8 × 19 (S) + IWRC lift cables. They are braided according to the principle of anti-twisting so they withstand the lifting force, so that the cable does not crack at the groove of the pulley wheel, ensuring absolute safety when operating.
Elevator elevator cable 8 × 19 (S) + FC
Components: 8 strands of cable are twisted together in a spiral around the core cable. Each strand of cable is twisted by 19 small wires. The inside of the cable usually has thorns, or pebbles, oiled jute cores.
Characteristics: A-1 lubricating standard. The inner core of the cable is oiled, when the cable works, it will lubricate the outside to lubricate the cable to help the cable operate flexibly and stable in devices.
Cable arrangement according to RHRL standard, with anti-twist, anti-rotation high.
Tensile strength 1770N / mm2, large load capacity, good durability.
Elevator cable 8 × 19 (S) + IWRC
Elevator cable 8 × 19 (S) + IWRC is composed of 8 strands x 19 strands, independent steel core.
Lubrication standard: A-1, RHRL style cable arrangement (right twist), common diameter: 8mm, 10mm, 12mm, weight: 8mm (0.22 kg / m), 10mm (0.334 kg / m), 12mm (0.494 kg / m), minimum breaking force: 8mm (30.8KN), 10mm (48.1KN), 12mm (69.2KN).
Bearing level: Grade (1620N / mm2), durable, flexible, fatigue, high strength, relatively low stretch, lubricated oil-filled core makes it easy to operate on pulleys.
In addition, steel cables used in elevators also have specifications 6xFi (29) FC, 6xFi (29) IWRC. Manufactured according to DIN standards, with certificates of Korean origin (CO, CQ).
