\r\n Due to the symmetric position of the four pivot arms, one-wheel, two-wheel and four-wheel steering (crab and steer) on all four sides is possible. The pivot arms' index plates can be clicked in to allow tracking either on stable standard gauge 62 cm (2'1'') or space-saving narrow gauge 36 cm (1'2''). There are two handles per pivot arm so that the dolly can also be comfortably carried in difficult situations (e.g. staircases). Extended carrying handles are available as an option.
\r\n To save space, the carrying handles are designed to lie within the radius of the Combi-Wheels. This way you don't have to put up with sticking-out, fold-away handles when carrying the dolly.
