Manitowoc has introduced its largest rough-terrain crane, the Grove RT9150E, with a 197-foot main boom. Maximum tip height is 312 feet. The main boom benefits from Grove’s patented Twin-Lock pinning technology designed to offer a lighter boom with greater strength. Maximum radius with the main boom is 180 feet and at that distance the crane can lift 3,800 pounds. A 36- to 59-foot bi-fold lattice swing-away extension offers farther reach.
