At present, the commonly used bucket elevators in China are vertcal type The relatively newer type wth standards in compliance with TB3926-85 are type TD and TH.
Structure style of TD type bucket elevator
(1) Driving device: There are two forms of driving device of TD type bucket elevator and each matched with YZ or ZQ (YY) type reducer. YZ type shaft-mounted reducer is directly sheathed on the spindle head. In this way the driving platform and coupling can be saved to achieve compact structure and light weight. Inside the device there is anisotropic roller brake with reliable brake. The reducer is with low noise and stable running and can float with main spindle to eliminate installation stress.
(2) TD type bucket elevator is equipped with four type buckets: Q type (shallow bucket), H type (arc bottom bucket), Zd type (mid deep bucket), Sd type (deep bucket).
