The THE BOSS® OF BRAKING SAFETY & PERFORMANCE
The BOSS® system has been developed based on the experience with the SOS system that has been already installed in more than 200 container cranes world wide.
BOSS® Brake Only Snag System
Conventional hydraulic anti snag systems have onlycone fixed tripping point (pressure relief valve). The BOSS® system is working with variable tripping points (each corner individually) depending on the actual corner load measurement and hoisting speed. The BOSS® PLC is pre-calculating the perfect tripping point for each load condition. Working with the best tripping points leads to faster snag detection and less stress in the wire ropes as well as in the crane structure.

How the BOSS® System Works
STEP 10 ms
Load Pins
Load pins are detecting an overload on one or more corners.
STEP 220 ms
BOSS® PLC
Cuts off power for BUEL®H thrusters, service brakes and BUEL® G for emergency brakes and hoist motors. Electrical reaction time is only 20ms until the brakes are switched off.
STEP 356 ms
SERVICE BRAKE
Service brakes apply full braking torque within 36ms after power off.
STEP 490 ms
EMERGENCY BRAKE
Emergency brakes apply full braking torque within 70ms after power off.
STEP 5100-267 ms
HOIST MOTION
Hoist motion will be stopped after up to 110ms. The total stopping time from snag detection to stand still is between 100 and 267ms*.
*Can variate per system.
