Mayo adds to Wolff luffer order: crane selection and site planning notes for engineers

30 Second Briefing
Mayo Civil Engineering has expanded its Wolffkran order to eight luffing-jib tower cranes, comprising three Wolff 166 B, two 235 B, two 275 B and one 355 B, bringing its Wolff fleet to 19 units on the standard TV20/UV20 2×2 m tower system. Two new Wolff 166 B cranes, each rated to 12 t with up to 55 m jibs for interleaved operation on tight sites, are already working on the £87.5m Phoenix Iron Works mixed-use scheme in Manchester. The larger units span 16–28 t capacities, with the 235 B hoist reaching 130 m/min from a 60 kW winch and the 355 B delivering 4 t at 60 m radius for high-rise work.
Technical Brief
- All eight luffers mount on Wolff’s standard TV20/UV20 2×2 m tower system for interchangeability.
- Three Wolff 166 B units are now working in tandem on the Phoenix Iron Works Ancoats site.
- Phoenix Iron Works is a £87.5m mixed-use development, implying sustained multi-year tower crane utilisation.
- Wolff 235 B’s 60 kW hoist delivering 130 m/min suits rapid high-cycle concrete frame pours.
- Wolff 275 B’s 24 t capacity covers heavy rebar cages, core formwork and large precast elements on high-rise frames.
- Wolff 355 B providing 4 t at 60 m radius enables full-perimeter coverage on tall, constrained footprints.
- Centralised service and maintenance from Wolffkran Ltd in Sheffield reduces downtime risk across Mayo’s dispersed fleet.
Our Take
With Mayo Civil Engineering’s Wolff tower crane fleet moving to 19 units, it joins Keltbray and Mace Construct in our coverage as a repeat Wolffkran user on major UK city-centre schemes, signalling that Wolff’s luffers are becoming a de facto standard for constrained urban sites like Ancoats and Westminster.
The mix of Wolff 166 B through 355 B models in this eight-crane order suggests Mayo is positioning to self-deliver a wide range of lift profiles on mid- to high-rise work, reducing reliance on external hire fleets at a time when our database shows Wolffkran UK is dealing with operator strikes and potential availability pinch points.
