Abstract
Description
Technical Field
[0001] The utility model generally relates to the technical field of cargo lifting equipment, in particular to a continuous and reciprocating mixed lifting system. Background Art
[0002] At present, elevators are mainly divided into continuous elevators and reciprocating elevators.

Reciprocating elevators use the up and down reciprocating motion of the lifting basket to realize vertical conveying of goods. Its advantage is that it can load and unload goods at different heights, providing a certain degree of flexibility. However, reciprocating elevators can only transport one piece of goods at a time, which limits its potential for high-efficiency transportation and leads to its relatively low conveying efficiency.
