The Trimble GS 550 system includes the cabin mounted GS550 radio display and compatible crane mounted GS and GC series sensors. The GS550 display 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 then 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 GS 550 system depends on the sensor configuration used and the rated capacity charts programmed (where applicable). The Trimble GS550 includes a USB port to facilitate software and chart updates and data logger downloads using a USB mass storage device (USB key).

The LSI Trimble GS550 display serves as the backbone of the wireless crane warning system.  The unit integrates both the display and operator interface as well as the computer that manages all the sensors and monitors the crane load chart.  The Trimble GS550 console utilizes direct sequence spread spectrum two way communication to reliably monitor up to 32 sensors in the harshest radio frequency environments with a reception range up to 4,300 feet.  A 6"long sunlight readable 2 line LCD display allows the operator a simple yet comprehensive overview of crane operations.

Trimble GS550 Additional Information

The Trimble GS550 display eliminates the cable breaks and costly installation fees of the past.  Once the ground and power wires are connected this self-install unit is ready to monitor load, angle, length, anti two block, wind speed and a selection of other sensors up to 32 units.  With its six inch long sunlight readable display, rest assured that viewing in all conditions, even with polarized sunglasses, will be unparalleled.  The GS550 has full capability to trigger lockouts if your crane has them installed for added safety.  Full load chart capability is realized with a simple software download via the USB port on the side of the unit.  Additional safety features include an optional supervisor level access password and full datalogger capabilities monitoring up to 16,000 events.

GS550 Sensor Reconnect after Battery Replacement

BTS Customers Get the Support They Need ...

The GS550 is a “plug and play” product. If there is a sensor failure, the system immediately informs the operator of the location of the issue. 99 percent of the time the operator can resolve the problem, which eliminates the need to have an on-site technician. Should you ever need to replace a sensor, the new sensor’s ID will automatically replace the old ID in the display. This only takes a few seconds to complete. The GS550 Display will trip function lockouts on cranes with installed solenoid valves when limits are exceeded. Each application has different requirements for system security.

The Trimble GS550 computer offers you the ability to easily set password restrictions for all key operating aspects of the system. In addition, the display has a supervisor password level. This extra level of security allows only a supervisor to access restricted areas of the display. The Trimble GS550 Display offers users one of the best sunlight readable displays found in the market today, if you wear polarized lenses, the display readability is unparalleled. Each GS550 Display ships standard with a built in data logger that can monitor up to 16,000 events. Data is downloaded with the onboard USB port to a USB drive. You can also utilize the USB port to upload load charts via a USB drive. The display can store over 3,500 pages of load charts 

Trimble GS550 Quick Reference Guide 

It can start as a basic Wind Speed, Anti Two Block, Load, or Boom Length Angle system, or can be utilized as a full rated capacity indicator, monitoring load charts.  All communication between LSI sensors and the GS550 Display is wireless. This innovative technology eliminates cables and costly installation charges. Wireless communication will help you avoid expensive and time consuming troubleshooting of cable breaks, junction boxes and more
