How To Deal With The Broken Elevator Cable?

Even if the elevator cables manufacturers use premium quality cables to design and intend safety features in the elevators, breakdown is common. The important is how you deal when an elevator breaks down. Let’s learn how professionals do it.

Snapping cables
In a cable elevator system, manufacturers bolt the steel cables to the car loop over a sheave. The sheave is located at the top of the elevator shaft used as a pulley with a grooved rim surface. The grooves of the sheave grip the steel cables, which move the cables when electric motor rotates the sheave. The cables used for car lifting are also connected to a counterweight. The counterweight and the car both ride together on steel rails.

Manufacturers intend every elevator cable using several lengths of steel materials that are wound around one another. However, a steel cable is also breakable. You must know that almost all pulley elevators have several cables installed. If any cable breaks, the other cables would hold the elevator car up.

Safeties of elevators
Imagine all the cables did snap and in this scenario, safeties of elevator come in. Safeties are braking systems available on the elevator car. Safeties are activated by a mechanical speed. Pulley is the manager that rotates when the elevator moves. When the pulley spins at faster rate, the centrifugal force helps activate the safeties.

What happens when safeties fail?
If the safeties failed, the car would slow down due to the friction generated from the rails along the pressure and shaft from the air at the bottom of the car. This would stop the car and you would keep going, slamming!

There are two things that would protect the blow. The elevator car would compress the air at the shaft bottom as it fell. The air pressure would help slow down the speed of elevator car. Most of the cable elevators include shock absorber in the design- this is a piston in an oil-filled cylinder.

All these features would protect you and provide you a chance of surviving any elevator breakdown. Major design considerations made by elevator traveling cable manufacturers. There are key considerations that elevator traveling cable manufacturers make for the cable design-

  1. Cable strength
  2. Flexibility
  3. Torsion balance
  4. Flame resistance
  5. Abrasion resistance
  6. Low temperature performance

Manufacturing team takes care of the design and use steel support as a center member in a round cable and as critical support member in flat construction. They achieve the cable flexibility by right selection of materials and the method of constructing the cable.

Abrasion resistance, low temperature performance and flame resistance are addressed through the materials applied for jacketing and insulating the cable. PVC is a common choice among thermoplastics for its good performance and cost effectiveness.
