ACT-8 mast climbing work platform

Work platforms



The ACT-8 work platform combines safety, flexibility and power. It distinguishes itself by its versatility and represents the best choice for general contractors and those specialized in repointing, glazing, E.I.F.S., metal framing, etc. The ACT-8 is recognized as the solution to vertical access challenges encountered on new building job sites or during restoration or deconstruction projects.

The ACT-8 work platform also provides safe environment for repairs and maintenance of structural works. Whether it is for new construction or rehabilitation, for concrete surface preparation or formworks installation, that mastclimber represents the perfect solution for vertical access to particular structures. No project is too big for the ACT-8. For many years, it has being used for works such as bridge or interchange concrete pilars construction or fixing, for dams repairs, and for smokestack or industrial chimney demolition.

The ACT-8 fully automated system allows a quick lifting and an exact positioning at the desired height.


Whether the ACT-8 is mounted on a ground base or a freestanding base equipped with adjustable outriggers, the initial installation and repositioning can be quickly accomplished. Also, the ability to expand the upper work area and install a low floor on the outriggers, allows workers to enjoy a productive and safe environment: the equipment is always at hand. Whether the wall is straight, curved or irregular, the lower work area adapts to all architectural forms.


The ACT-8 offers a large and safe workplace and a heavy payload capacity. It brings new ways to complete heavy works as it can support excavators equipped with hydraulic hammer, crusher or shear and other robots and construction equipment. Its anchoring system allows stability of the platform and does not interfere with its displacement. Productivity is guaranteed.

Edmonton, AB, Canada, 2012


Edmonton International Airport

The ACT-8 and FRSM-20K platforms were used for the realization of metal cladding work on a new terminal. The architectural design of the building with its curved shapes and variable size windows, in addition to the impossibility of anchoring itself to certain floors and concrete slabs, were challenges that required unusual solutions.

Pitt Meadows, BC, Canada, 2010


Pitt River Bridge

Twelve ACT-8 work platforms were used for the construction of a cable-stayed bridge in the Vancouver area. For this project, Fraco has developed front extensions that allowed access to the sides of each pillar.

St. Johns River Power Park cooling towers

Fraco has been approched by Structural to propose a solution allowing workers to access a 458' high hyperbolic structure. Works to be completed consisted in rebar replacement, concrete repair and cathodic protection. Twelve Fraco ACT-8 electric units were equipped with self-levelling devices were installed and tied-in without damaging existing rebar.
