Total control from Link-Belt
By Euan Youdale23 February 2011
Link-Belt will show its new crane operating system Link-Belt Pulse at ConExpo, Las Vegas in March.
The in-house designed systen is far more than just a rated capacity limiter (RCL), says the USA-based manufacturer. Link-Belt Pulse includes a boom extend mode controller (EMC), self-diagnostic capabilities and continuous monitoring of multiple crane functions and conditions.
For more than a year, the system endured field-testing in extreme climate and environment conditions. "Most importantly, because it's an in-house design, Link-Belt itself can better control customer support," said a company spokesman.
As a rated capacity limiter, the system shows maximum allowable load, load on hook, and crane geometry. It warns of an approaching overload or two block condition and shuts down relevant operations when necessary. It also monitors wind speed and warns the operator with a visual alarm. Pre-settable alarms can also assist in avoiding obstructions on the job site.
For boom operation, it clearly animates the boom's mode of extension. And for cranes equipped with pinning and latching booms, it displays pin and latch status and telescope cylinder travel. All information for telescope operation can be accessed and viewed in real time.
Moreover, Link-Belt Pulse can monitor and control counterweight removal and installation and even fine metering of the winches if the crane is so equipped.
Extensive customer input means diagnostic functions are simple to understand, says the company. They show repair faults in all areas including sensor data. Faults are indicated by a short message rather than an undecipherable code and, with the press of a button, the system gives further information about the fault and how to clear it.
At ConExpo, Link-Belt Pulse will be shown on the TCC-1100, HTC-8690, RTC-8090 Series II and ATC-3275.
