Txhawm rau nqa 6 meters siv cov aluminium alloy txhawb nqa (xws li cov ntu (lossis theem) yuav tsum yog nyob ntawm txhua ntu thiab lawv zes / Telescope mus rau lwm lwm tus.
Txoj cai dav dav:
Txhua seem ntawm mast feem ntau sib tshooj nrog rau tom ntej rau kev ruaj khov, yog li ntawd nqa qhov siab ib feem ntau nyob ib ncig ntawm 1.2 txog 1.8 meters.
Mus nqa rau 6 m platform qhov siab:
Koj feem ntau xav tau 3 cov ntu txhuas mast.
Txhua ntu yuav txuas ntxiv kwv yees li 2 metres, xav txog qee qhov sib tshooj.
Qhov siab ua haujlwm (tus neeg teb xov tooj mus txog) feem ntau yog 2 meters saum toj no platform qhov siab, yog li ib lub platform qhov siab txhawb nqa txog 8 m ua haujlwm qhov siab.
Cim npe nrov: 6m Ntsug Nqa, Suav, Tuam Tshoj, Chaw Tsim Tshuaj, Hoobkas, Yuav Khoom Siv, Kev Muag Khoom Siv, Kev Muag Khoom Siv Hauv Suav
