The VSL Slipform system has been used in the construction of silos, storage tanks, containment structures, chimneys, cooling stacks and bridge piers and pylons for over 20 years. Slipforming is advantageous when rapid construction between 2 and 6 m per 24 hours is required which results from continuous working and forms a monolithic structure free from construction joints. The system is raised by hydraulic jacks with upper working platforms for reinforcement fixing and concrete placement and a suspended scaffolding for finishing works. Climbforming
VSL has also been active in Climbforming for over 20 years. The VSL Climbform System is a self climbing heavy duty construction platform used primarily to lift static panel vertical wall formwork. The system provides the wall designer with complete flexibility in both the structural design and selection of finishes. The system is particularly adapted to the construction of high-rise building cores.
The 6-m high VSL Climbform has three platform levels, and the formwork panels hanging from the external frame and internal platforms permit pours over a height of 4.2 m. The internal steel platforms, incorporating the formpanel hooks and rollers, are specifically designed and manufactured for each project, guaranteeing accurate and economic assembly operations.
VSL Climbform permits an excellent production ratio with accurate placing of door frames, openings, blackouts, cast-in components and direct placing of prefabricated reinforcement cages. Another advantage lies in the safety of the Climbform. The VSL service package includes: feasibility studies and preliminary consultation and pricing; tender design and planning; design, manufacture and supply of equipment; leasing, training of site-staff, supervision of the works for the first few levels, followed by dismantling operation
