This week at its CraneFest, Link-Belt debuted the RTC-8080 Series II rough-terrain crane, featuring 80 tons of capacity, a full-power, four-section boom, and the Link-Belt Pulse total crane operating system. According to Rick Curnutte, Link-Belt’s telescopic crane product manager, the newest addition to the RT lineup “hits the the mark between the RTC-8065 Series II and RTC-8090 Series II. It has all of the cutting edge features that customers and operators alike have come to expect in the Series II line, plus other new features.” Some of those new features include platform guardrails, a three-piece bi-fold fly, and improved capacity. The RTC-8080 Series II replaces the RTC-8075 model.
Boom and Jib Features
The RTC-8080 Series II features a 41- to 127-foot, four-section, full-power formed boom. For maintenance, Link-Belt’s standard Teflon wear pucks are impregnated in the wear pad surfaces so the boom requires no grease. The boom, combined with removable, modular counterweights, helps reduce the transport weight to less than 90,000 pounds. A remote control boom flood light attached to the base section of the telescopic boom can be used as a spotlight when working at night.
Three on-board fly options are available; they feature four manual offset positions of 2, 15 30, and 45 degrees. These fly combinations provide up to an additional 64 feet of on-board reach. One of the three on-board fly offerings is the three-piece, bi-fold lattice fly, which features a 10-foot integrated fly that is similar to what was first introduced on the RTC-80130 Series II and HTC-3140LB cranes. It will have two bottom sheaves for mutli-part line reeving and have over 20 tons of capacity. No more hauling a separate specialized fly to the jobsite and then trying to figure out an easy way to install it – everything you need stows neatly on the crane. Link-Belt will also be providing lift procedures for two line, one load operation from the main boom head and from the 10-foot fly. The full 64-foot on-board fly bring the tip height to 199 feet.
The winches deliver 18,500 pounds of line pull and 460 fpm of line speed. Other available features include rollers and last layer/third wrap indication both with and without function kickout. Winch operations are also fully compliant to the latest OSHA standards.
Power and drive
Powering the RTC-8080 Series II is the 270-hp Cummins QSB 6.7L with a Tier 4i/Stage IIIB emission compliant engine. A direct-mount power shift transmission brings the power to the wheels. It has six forward and six reverse speeds. A switch in the operator’s cab controls the four steering modes: independent front, independent rear, all wheel, and diagonal.
The RTC-8080 Series II uses an automotive-style, four-link suspension. The fully independent rear suspension reduces bouncing and improves handling both on and off the road. For an even better ride, Link-Belt’s patented Hydro-gas Ride suspension is available as an option. At higher road speeds, Hydro-gas Ride provides a level of comfort and handling unmatched by other rough terrain cranes.
Cab and Carrier Access
For crane operators, there are a total of six points of access to the flat deck of the carrier frame. The front and rear lower steps can be folded to avoid damage during transport. A ladder has been incorporated into the upper sheet metal to allow access to an upper work platform with a folding guardrail. With large, swing-out doors revealing the entire engine compartment, it is easy to monitor routine checks of power-terrain components as well as fluid levels.
The operator’s cab features a large viewing window that minimizes blind spots and has well placed controls and readouts, including Link-Belt’s Pulse total crane operating system that incorporates a user-friendly display that is graphically oriented for the rated capacity limiter, boom extend modes, and more.
