Chapter 4: Operating Principle

4-1 Operating principle of brake

Brake operation

Spring force caused by brake spring and the air pressure supplied from brake operating port work

on brake shoe 1 fixed with brake holder, bend brake plate fixed on head cover on both sides, and

stop slider by putting brake plate between brake shoe 1 and brake shoe 2 fixed on the slider side.

Brake release

The air pressure supplied from brake releasing port work on diaphragm, decline brake spring, and

cancel brake.
