Safety Brake

SBD-A series hydraulic safety (emergency) brake is a high-power braking device used on a low-speed shaft (reel shaft). It can be widely used for emergency safety braking of large and medium-sized cranes, port loading and unloading machinery, and low-speed shafts of boom lifting mechanisms.

Basic parameters:

Product model: SBD100-A, SBD125-A, SBD160-A, SBD200-A, SBD250-A, SBD315-A

Applicable disc diameter: Ø800mm≤ØD≤Ø1800mm

Braking force: 72KN-220KN

Braking torque: M=μ×d1×F(NM)

Detailed explanation:

μ—Calculated value of friction coefficient μ=0.35

d1—Calculated friction diameter of brake disc, d1=D-130(mm)

F—Total clamping force during braking (KN)

Note:

1) The brake disc diameter is used for the diameter φ800≤φD≤1800, if you need other disc diameters, please contact us directly;

2) d2—allowable outer diameter of larger reel or link hub, d2=D-270(mm).
