Grove unveils heavy-duty jib for GRT9165

Grove is offering a new heavy-duty jib extension for the Grove GRT9165 rough-terrain crane that increases the 165-ton crane’s utilization abilities. It provides a competitive edge for setting precast concrete panels, the company said.

Precast concrete yields added environmental benefits as the hollow core uses half the amount of concrete without compromising strength.

The jib is 12.5 feet long and designed with two sheaves, for up to four parts of line and is hydraulically offsettable from 0° to 50°. The stout jib has a max lifting capacity of 68,600 pounds. The two-hook design also gives operators tight precision when positioning panels.

The heavy-duty jib was designed to meet the fast-changing precast concrete panel market, one of the most common off-site techniques used during construction. This type of work is expected to grow 5.6 percent annually over the next five years alone.

Wisconsin-based design-build contractor Miron Construction Co. (Miron) is the first customer to use the new jib on its GRT9165. Miron’s clients are rapidly shifting to precast concrete for healthcare, warehouse, manufacturing and higher education builds across the country.

The heavy-duty jib extension is available for order on all new Grove GRT9165 rough-terrain cranes and as a retrofit for cranes in the field.

“It takes a larger crane to lift and rotate the concrete panels and vertically set them in place,” said Pete Klosterman, executive vice president, field resources for Miron. “Our precast jobs have a short duration and we wanted to minimize transport and setup costs.”

In June, Miron used the jib to set panels for a new high school in western Wisconsin. The GRT9165 was configured with its full 56,800 lbs of counterweight and working at a max tip height of 124 feet, with a 50-ft radius and zero-degree offset.
