Abstract: An improved liner hanger comprises a mandrel having a piston housing and a plurality of spring slots disposed on the outer wall surface of the mandrel. Each spring slot having at least one spring disposed therein. The liner hanger also has a slip housing having a plurality of slips operatively associated therewith, a spring adjustment sleeve, and an adjustment sleeve ring. The location of the spring slots on the outer wall surface of the mandrel permits an increase in the number of springs utilized for setting the liner hanger. The spring adjustment sleeve and adjustment sleeve ring permit easy and safe assembly and disassembly of the liner hanger. Additionally, when actuated to move from its run-in position to its set position, springs, slip housing, and slips all move upward.
