TYPE USB 5 III
SERVICE BRAKES – Tips USB
These brakes are designed considering the specific demands of crane-, lifting- and material handling applications and is the consequent result of the continuous research and development performed by SIBRE.
ADVANTAGES
- Standardized functional principle, available in 5 different sizes
Designed for all applications in a crane (gantry, boom, slewing, hoist)
Identical conditions in regards to installation, adjustment and maintenance
- Improved brake linings
More stable friction coefficient and brake torque
Extended lifetime
- Parallel opening of brake shoes
Simplified alignment of the brake system
Minimized risk of sliding between disc and linings
- Optimized spring guiding unit
Reduced noise emission
Extended lifetime of brake spring
- Upgraded manual release system
Increased operational safety for manual load lowering
- Enhanced corrosion protection
By design features and improved coating
- Additional options for status monitoring
Load cells for measuring the brake torque
PT100 temperature sensors for the brake linings
Linear position sensor for monitoring of thruster stroke
Linear position sensor for torque adjustment
CHARACTERISTICS
- Brake linings of sintered material with standard brake disc material S355J2G3
- The specified braking torques are based on an average friction coefficient μm = 0,4 with grinded and optimum conditioned brake linings up to a sliding speed of 60 m/s. Deviating parameters can reduce the friction-coefficient
- Weight without thruster: 285 kg
- Thruster position: For 500/8 as shown, all others turned by 180°
- Available options:
– Special executions for low and high ambient temperature
– Manual release
– Inductive sensors for indication “brake open”, “brake closed” and/ or “pad wear”
– Temperature sensor for brake linings
– Load cell for monitoring of clamping force
