Prior to Use Series CL Construction Principle/Applicable Series: CLJ2, CLM2, CLG1, MLGC Spring locking type Tapered brake piston Roller Brake arm Brake shoe Release port Fulcrum A (Rotary axis) Air pressure supply Application point C Power point B Brake spring Pressurized lock port (Plug with breathing hole for spring lock) Air pressure exhaust Unlocked state Locked state Spring locking (Exhaust locking) The spring force that is applied to the tapered brake piston becomes amplified through the wedge effect. This force becomes further amplified to the power of AB/AC through the mechanical advantage of a lever and acts on the brake shoe, which in turn, applies a large force to tighten and lock the piston rod. To disengage the lock, air pressure is supplied through the unlocking port, thus disengaging the brake spring force. Brake piston is operated by air pressure. Unlocked state Locked state Pneumatic locking type Air pressure supply Air pressure exhaust Air pressure exhaust Air pressure supply Brake piston is operated by air pressure and spring force. Unlocked state Locked state Spring and pneumatic locking type Air pressure supply Air pressure exhaust Air pressure exhaust Air pressure supply 706
