                influence factors

                Suzhou Diao Elevator Co.,Ltd | Updated: Jun 29, 2016

                Balance coefficients

                Due to the drag of gravity is the car together with the heavy gravity through the towline acting on the sheave grooves, heavy is hauling rope and sheave grooves create friction necessary. With it, it is easy to make the car weight and payload weight in balance, this can also be in the elevator runs, reducing transmission device power consumption. Also known as the balance weight, relative to the other end of the car hanging in the sheave, play the role of balancing car weight.

                Focus when the car with heavy emphasis on equality, T1=T2, without considering the weight of wire rope changes, traction can overcome friction to ease operation. But the weight of the car with cargo (passenger) vary, so fixed on impossible in all load balancing the weight of the car. Therefore the heavy weight match will directly affect the towing power and power transmission.

                To make the elevator loaded and unloaded situations, its load torque equal to the absolute value of basic, national standard equilibrium coefficient K=0. 4~0. 5, counterbalancing 40%~50% rated load. The total weight of the counterweight side should be equal to the weight of the car plus 0. 4~0. 5 times the rated load. This 0. 4~0. 5 is the balancing factor.
