Updated crawler promises easy luffing

A new boom design is the “capstone” of the new 298 Series 2 lattice boom crawler crane from Link-Belt Construction Equipment, says a news release from the manufacturer, which is based in Lexington, Ky.

The boom design “allows the working combination boom tip section to remain in place when transitioning from conventional mode to luffer with a maximum combination of 180 feet of luffing boom and 195 feet of luffing jib,” the news release says.

The 250-ton 298 Series 2 is based on Link-Belt’s 298 HSL, which the company describes as a “highly successful job-proven predecessor.”

Since its introduction in 2007, the 298 HSL has worked from rental fleets around the globe, from dry docks in Brazil to tunnel construction projects in the New York borough of Queens.

“We believe the new transport package and combination boom tip absolutely completes our customers’ wish list,” the news release quotes Scott Knight, Link-Belt’s product manager of lattice and telescopic crawler cranes.

To simplify conversion to a luffing configuration the new crane has such features as semi-bore weldments for pin locations, “point of use” storage provisions for all components, and stop bolts for quick pin alignments, the release noted.

In addition, the crane has a luffing jib transport package with lifting lugs that simplifies and expedites luffer assembly. “The rear post will scissor into place by means of alignment links,” the release notes. “The transport package also comes assembled with nylon rope reeving to assist with initial luffing jib wire rope hoist reeving. Once the rear post is in working position, all luffing jib pendant connections are made and the luffer is ready to be raised for work. All assembly is done from the ground with no work at height exposure.”

A new base section and 12-inch wide boom walkway are among the other features on the 298 Series 2, which replaces dual wire rope pendants with bar pendants that have storage brackets. A newly designed 25-ton capacity retractable auxiliary lifting sheave offers two parts of line.

The conventional boom length at 60 feet of 290 feet on the Series 2, which comes with a Cummins QSL 9 Tier 4 engine, is the same as on the 298 HSL.

The new model’s Eco winch system provides greater fuel efficiency, lower operating costs, and fewer emissions, the release noted. An onboard high-resolution rearview camera helps the operator monitor the job site. And an audio-visual travel alarm system “informs crew members on the ground.”
