Sbd-b series safety brake

Application:



SBD □ - B series hydraulic safety (emergency) brake is a high-power braking device used on the low-speed shaft (drum shaft). It can be widely used for the emergency safety braking of the low-speed shaft of large and medium-sized cranes, port loading and unloading machinery and boom tilting mechanism. Working braking and emergency safety braking of mine winch, hoist and high-power inclined belt conveyor, safety braking of driving mechanism of cable car and cable crane, and safety (emergency) braking of low-speed shaft of hoisting mechanism of special crane such as casting crane.



Compliance with standards:



The technical requirements of caliper disc brake shall comply with JB / t10917-2008 standard.



Main features:



▲ normally closed design, safe and reliable; The special disc spring applies force for braking and is hydraulically driven for release (see the sample of hydraulic station for the selection of hydraulic station).



▲ the action is sensitive and the closing (opening) time is short.



▲ it can be equipped with switch opening limit, pad wear, limit limit limit and other switches for signal display or interlocking protection.



▲ high performance asbestos free hard friction pad, stable friction coefficient, no damage to brake disc, and insensitive to water medium and salt spray (seawater).



▲ reasonable sealing structure design and imported famous brand seals. Good effect and long service life.



▲ the installation position is flexible and the use, adjustment and maintenance are simple.



Working conditions:



◆ ambient temperature: - 20 ° C ~ + 50 ° C;



◆ relative humidity: ≤ 90%;



◆ optional hydraulic station (see the hydraulic station sample for the selection of hydraulic station);



◆ if there are special requirements, they shall be determined through negotiation when ordering.
