Towerlift

The original (or first generation) Towerlift was developed by Fagioli PSC in the 1980s and has stood the test of time in that we were still manufacturing new sections as recently as 2004. It was developed as an extremely heavy duty structural support system for use with Strand Jacks. It was specifically designed in modular form for ease of assembly, erection and worldwide transportation.

In its basic form it is assembled from only two members – legs and bracings. Bracings are connected to the legs by means of a single pin at each end. Two connection points are provided on all legs so that the same members may be assembled in either three-leg triangular of four-leg square format towers.

Because of its unrivalled versatility as a temporary structure Towerlift can be used in varying ways to produce the most economical lifting arrangement. Typical lifting arrangements have included:

• Two towers with crosshead beams.
• Four towers with crosshead beams.
• Two towers with cantilever beams.
• Independent inclined towers.
• Paired luffing towers.
• In addition most of these arrangements have been used with both triangular and square format towers and in guyed and unguyed configurations.
  

New Towerlift

As lift weights became heavier the original Towerlift system was being used closer and closer to its design capacity and therefore the New (or second generation) Towerlift was developed to cope with these increased lift weights. The design of the New Towerlift system includes the following features:

• 3,000 tonnes lift capacity using a four tower unguyed system to a height of 120m. Heights in excess of 120m are possible but the capacity will reduce. Likewise for short tower height the capacity will increase.
• Self-erect capability.
• Work and rest platforms at frequent intervals and caged ladders to comply with the latest health and safety requirements.

The New Towerlift system has the same basic structure – legs and bracings – as the original system and can be used in identical arrangements but with increased capacity.

Current and recent projects have included the following arrangements:

• Two towers with cantilever beams. Lift weight 635te. Tower height 78m (unguyed).
• Two towers with crosshead beams. Lift weight 608te. Tower height 90m (unguyed).
• Two towers with crosshead beams. Lift weight 1,053te. Tower height 67m (unguyed). Two identical lifts.
• Two towers with crosshead beams. Lift weight 547te. Tower height 44m (unguyed).
• Two towers with crosshead beams. Lift weight 1,350te. Tower height 96m (guyed). Lift and traverse load using 40m span beams.
• Two towers with crosshead beams. Lift weight 1,150te. Tower height 49m (unguyed). Two similar lifts.
• Two towers with crosshead beams. Lift weight 1,400te. Tower height 117m (guyed).
