Link-Belt RTC-8090 Series II:
Heavyweight lifter, lightweight mover
Lexington, KY—Link-Belt introduces its new RTC-8090 Series II, 90-ton (80.0 mt) rough terrain crane featuring an innovative new boom design and incredible lift capacities giving this RT serious muscle and light-weight transportability.
It’s All in the Boom
The RTC-8090 Series II features Link-Belt’s patented locking and
latching system for the 38–140-ft (11.6–42.7 m), five-section
boom—a first for an RT crane. This boom design uses a single hydraulic
cylinder to move all five boom sections, one at a time. And, unlike
other cranes with latching booms, there is no deduct in the lift chart
for telescoping a load. To make maintenance a cinch, the design
incorporates Teflon wear pucks impregnated in the wear pad surfaces so
the boom requires no grease whatsoever. The single cylinder design
allows huge lift capacities while yielding a light working weight. The
boom, combined with removable, modular counterweights, helps reduce the
transport weight to under 90,000 lbs
(40 823.3 kg).
The 8090 has a maximum tip height of 238 ft (72.6 m) with the additional two 16-ft (4.9 m) lattice inserts installed between the boom head and the optional 35–58-ft (10.7–17.7 m) bi-folding lattice. All attachment combinations have offset positions of 2, 15, 30, and 45 degrees.
A Better View
Link-Belt innovation goes far beyond the RTC-8090’s boom and into the
operator’s cab. The galvaneal cab, with curved front window glass,
dramatically increases visibility at high boom angles. For optimum
operator productivity and comfort, the 6-way adjustable seat perfectly
matches up to the controls. Lift-up armrests and a wide sliding door
allow easy access. All gauges and switches are in the operator’s forward
line of sight and backlit for low-light operation. The optional air
conditioner integrates into the heating and ventilation system, which
has directional vents in the front of the cab.
Movin’
Out
Powering the RTC-8090 Series II is the 225-horsepower (167.8 kW)
Caterpillar C6.6 engine. A direct-mount Spicer powershift 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:
two-wheel front, two-wheel rear, four-wheel, and crab.
Handles Like a Sports Car
The RTC-8090 uses an automotive style, 4-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. This system’s
charged accumulator serves as a shock absorber improving carrier
stability. At higher road speeds, Hydro-gas Ride™ provides a level of
comfort and handling unmatched by other rough terrain cranes.
Winches
that Perform
The winches deliver 16,880 lbs (7 656.6 kg) of line pull and 341
fpm
(104 m/min) of line speed. Spooled onto the winch drum is a
durable 0.75-in (19 mm) diameter four strand, low torque wire
rope. Rotation resistant rope is available as an option.
Loads of Standard Features
Naturally, the new RTC-8090 Series II comes with a host of job-proven
standard features including:
- Six points of access to the carrier deck
- Large, swing-out engine hood doors for easy service
- The CALC (Confined Area Lifting Capacities) system
