Overview
The GS550 system includes the cabin mounted GS550 radio display and compatible crane
mounted sensors. The GS550 creates a two-way radio network with the sensors to bring required
lift data to the operator. Hoist load, boom and jib angles, boom length, wind speed and pending
two-block can be detected and indicated to the operator in real time. Working load radius can be
calculated and compared to a rated capacity chart (if programmed). Furthermore the GS550 can
be programmed to generate warnings, alarms and lockout commands, all triggered by adjustable
thresholds and limits. All these events can be recorded by the data logger with a time and date
stamp. The exact operational function of the GS550 system depends on the sensor configuration
used and the rated capacity charts programmed (where applicable). The GS550 includes an
infrared port to facilitate software and chart updates and data logger downloads using a compatible
palm or cell phone. Compatible sensors include the GS050 anti-two-block, the GC series load cells
and GS001 series line rider and load pin transmitters, the GS010 angle sensors, the GS011 angle
sensor and length transmitter and the GS020 wind speed sensor. The GS550 system is designed
as an operator aide and is in no way a substitute for safe operating practice.
