The construction elevator is driven by joggling of gear and rack, two drive systems establish in top of the cage, co***red with the past three transmissions, it enlarged the power of electromotor and torque of the single speed reducer, reduced drive electromotor, thus increased the synchronism which the drive and the rack meshed, the effective solution three drive electromotor synchronized question, lengthened the drive service life; Reduced the noise in the cage and improves working conditions in the cage, it has facilitated the service and the maintenance. The electric cable pulley equipment may effective lengthen the electric cable the service life. It is suitable for the industry and civil and so on in the high-rise construction.
