A tracked mini crane that walks through a doorway, sets its outriggers on a floor slab and picks where nothing else fits.
What it is for
The spyder is the machine we bring when the lift is small but the access is the problem. It tracks through gates, gaps and finished spaces, then spreads four independently adjustable outriggers to work from a footprint most cranes cannot use at all.
Because the outriggers set independently, the machine works on stairs, slopes and split levels, and it can be set up tight to a wall on one side while reaching out on the other. It is the usual answer for interior picks, courtyards, rooftop terraces, glass and stone installation, mechanical rooms and backyard work behind a house.
