SB SBD Series Safety Brakes

APPLICATION
●Hydraulic safety (emergency) brakes are high-power braking devices which can be wildly used as emergency safety brake on low speed shafts for the lifting control and pitching mechanism of various large and middle crane. port handling machinery.

They are also applied for the same purpose ftor mine winder, lifter, elevators, belt Conveying machinery, cable cars, foundry and cable cranes and so on.

MAIN FEATURE
●Normally closed design, safe and reliable; speially-designed disc springs applied. hydraulic driving.Type selection of hydraulic power unit see "Manual for hydraulic power unit".
●Swift actions and short braking time.
●Be able to optionally equip with release limit and pad wear limit switch, which can realize signal indication and interlocking protection.
●Brake lining is made from non-asbestos hard material, which has high and stable friction performance, and it is insensitive to water, salt and other environmental agents.
●Excellent sealing ensure the brake long service life.

●Installing position is flexible, operation, adjustment and maintenance are easy.

ST ANDARDS COMPLIANT
●The technology requirements of safety brakes comply with JB/T 10917 -2008 standard.

OPERATING CONDITION
●Ambient temperature: -20℃- +40℃
●Relative humidity:≤90%
●Hydraulic power unit can be selected. Type selection of hydraulic power unit see "Manual for hydraulic power unit.
●Special requirements can be discussed before production.
