| New Link-Belt 90-ton RT crane  Link-Belt Construction Equipment's new RTC-8090 series II is a 90-ton rough terrain crane that features a new boom design and heightened lifting capacities. Link-Belt also unveiled an 80-ton version of the same crane, the RTC 8080-Series II, marketed to specific states with more stringent labor requirements for cranes rated above 80 tons. Link-Belt engineered its patented locking and latching systems into the 38- to 140-foot, five-section boom. Using a single hydraulic cylinder, the five boom sections move one at a time, which eliminates lift chart deducts for telescoping a load.The RTC-8090 has a maximum tip height of 238 feet with two additional 16-foot lattice inserts, installed between the boom head and the optional 35- to 58-foot bi-folding lattice. All attachment combinations have offset positions of 2°, 15°, 30°, and 45°. Visibility at high boom angles has been increased in the design of the galvaneal operator's cab with its curved front window glass. The operator's comfort and productivity levels have been heightened with a six-way adjustable seat matched to the controls. All gauges and switches, backlit for low-light operation, are in the operator's forward line of sight. The RTC-8090 is powered by a 225-hp Caterpillar C6.6 engine, is equipped with a direct-mount Spicer powershift transmission, and has six forward and six reverse speeds. A cablocated switch controls four steering modes: two-wheel front, two-wheel rear, four-wheel and crab. The crane is engineered with an automotive style, four-link suspension, and Link-Belt's patented Hydro-gas Ride suspension is an option. Its charged accumulator serves as a shock absorber improving carrier stability. write your comments about the article :: © 2006 Construction News :: home page |
