P4
Welded container house (crane-lift)
Complete welded box · one crane lift · relocatable as a unit
Overview
The most complete of the box forms: the steel frame is welded and the envelope, doors, windows and electrical package are fitted in the factory. The unit arrives as one closed box and is lifted into place by crane, with no panel assembly on site.
Suited to camps that need accommodation quickly and may lift the same units onto another site later. A spreader beam and a lifting plan are required; final weight and lifting points follow the signed drawing.
