The operating speed of the elevator and load the selection of motor and brake. The design of the traction rope, first choose a traction rope around the law, then the forces it to choose the number of the traction rope and cross-sectional area. Reducer is the main part of the design, according to motor speed, lift speed, traction wheel gear design parameters such as diameter. Lift is the use of traction on the rim of the traction rope friction groove transmit power, it must design and wear-resistant surface friction coefficient of the traction wheel. Rigid coupling used to ensure the transfer of power, but requires moderately high on both axes.
