What is the meaning of double straps in the construction elevator?

Answer:

One component of the elevator's drag system is the weight of the car. The other side of the car is connected to the top of the car by dragging a wire rope. It can be used for the energy saving of the elevator towing system, because the elevator load optimization is calculated by the theory calculation. The elevator should be calculated before the weight is weighed: the calculation principle is that the weight is equal to the weight of the car and half the load.
Used for heavy to offset the hoisting cage weight so as to realize energy-saving province electric hoist, by making use of the fixed pulley for heavy gravity into upward traction hanging basket of traction, so as to reduce the drive motor load, achieve energy saving.
With double cage for heavy, namely SCD200/200 series Is the two cages, each cage has a corresponding weight, the weight up and down in the elevator cage rise to energy conservation and reduce the reaction between the up and down, when you imagine front-rear door principle is about the same
