Masts have compact dimensions and low weight, enabling them to work in restricted spaces and on more sensitive floors than scissor and boom type platforms.
They typically offer good vertical heights but limited outreach, are all battery powered for quiet operation with some offering the option to drive at height whilst other use stabilisers to spread weight and level on uneven ground. All are suited to work indoors however many are rated for external use as well, machine weights start at under 400kg and all will easily fit through standard doorways
