New Grove RT770E Rough Terrain Crane for Sale The RT770E shares a common design platform with the RT765E-2 model, while providing higher nominal capacity and additional reach thanks to the 42 m (138 ft) five-section, full power MEGAFORM™ boom. The full vision cab ensures maximum visibility and operator comfort, while higher permissible line pull and faster line speed than competitive cranes allow for less rigging, higher efficiency and productivity on the jobsite. MEGAFORM™ boom: The superstructure features a full-power fivesection MEGAFORM™ boom that can reach to a maximum tip height of 44,6 m (146 ft). The sequence synchronized extension features telescopic boom sections via a pedal or single lever control Smooth operation: The RT770E has a quick-reeve boom nose and swingaway alignment device to help operators set up smoothly. Extensions: An optional bi-fold swingaway lattice extension easily stows on the side of the base boom for easy transport while providing on-board extension from 10,1 m - 17,1 m (33 ft - 56 ft) for a maximum tip height of 61,6 m (202 ft). By adding the 6,1 m (20 ft) insert, the maximum tip height can be extended to 67,3 m (221 ft).
