The 200S pedal ∞ntrolled hydraulic over-付de system  be fitted to the.SA.and.ST" Series brakes. The hydraulic portion from the foot pedal. The system provides the operator withof the over-吋de system functions in the same manner and utillzes the same basic    mponen the  SM" Series brake. This provides the operator with smooth slowing and stopping variable torque control with the electrícal actuator providing emergency stopping and parklng. 

OPERATI    操作

The electric actuato，r DC or AC，must be contìnuously rated and Is arranged to be independently "energized/released" during the normal operation of the crane.  An ON/OFF pushbutton is usually mounted in lhe b so that the operator can de-energize the electrìc actuator and set the brake in an emergency or for temporary parking.  Operation of the foot pedal allows the operator to apply torque to the brake wheel by .over-riding" the electric actuator through the hydraulic slave cylinder mounted on the brake pushrod.

 AC CRANES  AC吊車

The ﹒(and ST/E)type，3-phase AC brakes  n be fitted with a pedal operated (manual) hydraulìc override system. This type of brake combines a hydraulíc setlspring release brake wíth a spring setlel ectlIy released brake. 

These brakes retain all of the features and characteristics of the individual type ST and

ST/E 3-Phase AC Hy-Thrust Operated brakes and the“SM"Hydraulic brakes，

 DC CRANES  DC吊車

The DC Magnet Operated Brakes (Type SA) can be fitted with a pedal operated (manual) hydraulic over-ride system. The brake designalion then becomes a SAlM Type. This type of brake includes all the features of the individual.SA   Type DC magnet operated brakes and the.SM.Type hydraullc (pedal) operated brakes.
brake combines a hydraulic seUspring release brake with a spring setlmagnetilIy released brake. The SAlM Type shoe

The “SAlM" DC brake mat also must be used on an AC powered crane in conjuction with a suitable rectifier panel.

A torque-limiting unit (TLU) is available as an option.This unit be set 10 limit the maximum toue applied to the brake，OPTlONA   'SC POSITION independent of the force exerted on the pedal.
