How the cranes are dismantled from the roof (7/7) - 6" Derrick boom down and 4" Derrick boom up

[@RELAVI]

So you need, three other cranes to tear done one. Why they dont use a climbing crane?

Tower crane masts are a great cost then. Also, the sites in Hong Kong are mostly narrow, it's not easy to assemble luffing fly jib for mobile cranes. This method is the most promising!

@@lclun thank you for your reply, appreciate it! Love all your videos mate

Very interesting video! Do You know which company makes these cranes? And how these cranes dismantling without mobile cranes and other derrick cranes, which mechanismes use? Thank You.

[@lclun]

These derrick cranes are made by local engineers, welding plates and tubes. Not much space to rig a mobile crane with luffing jib in the narrow sites in Hong Kong.

@@ДмитрийРевенков-о1ь Honestly speaking, not easy to take videos as the schedule of erection or dismantling always change. Do remember to watch my other videos!
