Abstract
Mention our daily lives in both industrial production and play an important role. This brings us a lot of benefits. Lift feature is very much, in our life we in many business building will use the elevator, lift as the elevator performance very much the same, we use the lift time can also be based on their own needs to elevator set.
According to this study the heavy transport of floor material is applied to the floor material.According to the actual demand can be taken as follows: motor choice ( belt reducer ) as the driving force, using a chain transmission to drive form, the main mechanism adopts a frame type structure design. On the Z axis lift key parts design calculation and checking, after verification can achieve the desired design objectives and requirements.
Key Words: elevator,  material lifting,  chain drive,  frame struc
