While occupational hazards have been a concern for long , harmful habits have reportedly led to injuries and other work related health issues in the automobile industry . A puller,also called an extractor, can sufficiently be used to safely remove components stuck in a shaft.Development of puller for removal of components from shaft started almost a century ago .
There are two types of pullers namely;the hydraulic and the mechanical types.The hydraulic pullers work base on hydraulic principle.

The mechanical puller is a simple device in that it has few and easy to construct components, namely; the screw, a bolt/head, linkage arm (jaw) and a handle. The jaws are either two or three. Currently, there exist different jaw designs .The mechanical pullers work base on the principle of power screw,that is, they change angular motion into linear motion totransmit power.
