The telescoping mast consists of three single tubes and a telescoping boom. The telescoping
cylinder pushes the tube 4 (R4) out. Tube 3 is extended at the same time via flyer chains.
Telescoping retract functions in the reverse direction. Recuperating chains are installed in
the mast system for this reason.
The boom can be extended manually from 4,5 m to 8,8 m.
The boom can be erected in three stages (135°, 150°, 165°) via the peg fixture. Use the
winch to erect the boom.
