MEGAFORM
™ boom with patented TWIN-LOCK ™ boom pinning
system. Maximum tip height: 207 ft. (63 m).
Boom Elevation
Single lift cylinder with safety valve provides boom angle from -
1.5° to +82°.
* Telescopic Swingaway Extension
36 ft. - 62 ft. (11 m - 19 m) telescoping offsettable swingaway
extension. Offsettable at 5° and 30°.
Lattice Jib
Luffing Jib is a lattice design with lengths of 69 ft. -200 ft. (21 m -
61m) in sections of 26 ft. (8 m). The luffing jib converts to a fixed
offset lattice jib using an offset angle adapter and provides
