gantry

Forty-five Just Stop Oil protesters climbed gantries on the motorway, forcing police to stop the traffic, in an attempt to cause gridlock across southern England.

The ground's TV gantry is notorious for the precarious journey across its roof to access it.

"Apologies to the listeners. You can understand the emotion. Back to you in the gantry."

In partnership with architects like Benjamin Albertson and Rad Studio, the robotic gantry system can produce more free-form designs than traditional construction, with tight curves, circles and other elements.

The group has drawn attention, criticism and jail terms for protests ranging from throwing soup on Vincent van Gogh's Sunflowers and spray-painting Charles Darwin's grave, to climbing on M25 gantries.
