EXTENDING ACCESS POSSIBILITIES


Preassembled, needing only a small footprint and able to self-extend during shaft sinking as well as remain for permanent use afterward, XL Industries’ XE5 mechanised access lift system has worked on some major tunnel projects

Accessing underground works, especially on urban tunnel projects, is always a challenge when seeking options to overcome the vertical distance from the surface in ways that are logistically and economically efficient but most of all reliably safe. Ladder scaffolding, crane lowered hoists, and manrider cages have been used on different projects, depending on many factors.

In 2019, on the metro tunnel works in Paris, France, XL


Industries brought into service its XE5 small footprint mechanised access lift – able to be used, and extended, while shaft sinking was underway. The shafts would be excavated deeper in steps and then the suspended and wall-tied support mast for the XE5 would be extended down in 1.5m steps – each section being added from
