①The formwork travels through main girder supported by inner form, and adopts double-line hydraulic lifting system to achieve high precision, compact structure, whole contraction and easy demoulding.
②Easy operation, integrally lifting and dragging inner form into formwork, can achieve whole demoulding after concrete pouring without any manual dismantling, greatly reduces labor intensity and improves working efficiency.
③Until the end of 2013, nearly 2,000 sets of box girder formwork we manufactured are used in over 50 domestic high-speed railway, highway, intercity railway and subway construction.
