DUTY PROP Features and advantages： 1、Reasonable stress , high bearing capacity , which can effectively reduce the construction cost , the support bar is not bound by a fixed plane size. Particularly strong versatility , and can adapt to different height , different thickness of cast-in-place reinforced concrete floor slab mould engineering. Don't need to be level connection, can stand on its own , good stability , etc . 2、Under the condition of same area , adjustable steel prop consumption quantity is little than other scaffoldings , so the vertical empty tower crane , high work efficiency .3、The scene of the support bar is relatively less , the operating space is large , traffic /material handling , easy to manage . 4、Templates , steel props , primary and secondary beams , dismantled and can focus on handling the material on the platform by the vertical transportation of tower crane , can also be used by workers from the stairs , less subject to the limit of the machinery , has a certain flexibility .5、For the project with larger area , can take " small water period of " construction method .
