The HC3 Series of telescopic and articulated boom lifts feature platform heights ranging from 40 to 86 feet. “HC” stands for high capacity.

The eight models in the Hi-Capacity lineup are the company’s response to the new ANSI standards, which require mobile elevating work platforms, or MEWPs, to automatically limit operation when nearing overload. In the past, operators were responsible for not overloading the platform, but it was found that loads were often exceeding capacity, possibly becoming unsafe.

The load-sensing technology, however, prevents that, and most MEWP manufacturers are boosting platform capacity so operators won’t face machine cutoff or reduced operation.

In JLG’s case, it made its load-sensing technology automatically limit operation to the lift’s allowable capacity zone rather than cutting off the machine. JLG also made the HC3 boom lifts auto-calibrating, with no need for external weights. “This saves time and effort, while increasing productivity,” the company says.

The platforms can hold three workers and tools in three capacity zones. Each of the models has a restricted capacity zone of 750 and of 1,000 pounds. The unrestricted capacity zone ranges from 500 to 660 pounds, depending on the model.
