Poclain is a family company founded by Georges Bataille in France in 1927, then developed by his sons Pierre and Claude Bataille, with help from Jacques and Bernard Bataille.

Poclain produced excavators, and was leader on the French and world market thanks to a revolutionary hydraulic motor. The Batailles were forced to sell the company to Case in 1974, an American company, which then took over completely in 1987, leaving them (the Batailles) only the Hydraulics division, which is still trading today.

Poclain make Radial Piston Hydraulic Motors which are mostly used in industrial and off highway vehicles, their biggest competition in this area is Rexroth of Scotland who are now a subsidiary of Bosch AG.
