Description
Technical field
The present invention relates to trolley fields, more particularly, to a kind of hand barrow.
Background technology
Logistics is article from supply into the physical flow process for receiving ground, according to actual needs, by transport, storage,
The functions such as buying, handling, packaging, circulation and process, dispatching, information processing, which combine, realizes the mistake of user's requirement
Journey.In the process, trolley, which becomes, transports one of essential articles for use of cargo.
Traditional trolley be suitable for transport cargo in small range, short distance, have the characteristics that it is simple, flexible, still
Some cargos need first to be weighed and counted before carrying, then transport again, this just needs to complete to carry twice, i.e., first carries
It is put on scale and is weighed, then moved on trolley again, this adds increased labor intensity, reduce efficiency, it is therefore proposed that one
The hand barrow that kind solves the above problems is actually necessary.
Invention content
The present invention is at least one defect overcome described in the above-mentioned prior art（It is insufficient）, a kind of hand barrow is provided.
