Summary:The invention discloses an energy-saving type parallel elevator system which comprises a first car, a hoist rope, a first traction device, a second traction device, a second car, a counterweight, at least one counterweight wheel, a hoisting mechanism, a haulage tope, a balance weight, a first clutch mechanism and a second clutch mechanism. One end of the hoist rope is hung with the first car, thenthe hoist rope bypasses a first traction wheel on the first traction device, the counterweight wheel and a second traction wheel on the second traction device in order, and the other end of the hoistrope is hung with the second car. The counterweight is hung on the counterweight wheel and is used as the shared counterweight of the first car and the second car. When load enters into the first carand an elevator control system judges that the first traction device needs to be controlled in a mode of save energy, a clutch in the first clutch mechanism is engaged, and torque loaded on the hoisting mechanism by the balanc
