The Mast Truck for a Zeppelin is its ‘airport’. It needs to dock with the mast for refueling and for being taken in and out of the hangar. It’s also a place of refuge at the start and end of the day and for windy weather. The Zeppelin doesn’t need to be on the mast to transfer passengers, which is actually pretty neat and means a changeover can be done in a matter of minutes.
Here at Zeppelin they have two mast trucks and their favorite is this four-axle monster that carries the hydraulic masthead, portable generator, supplies, cables etc. My comment to Brian about the ground support equipment we need (the title of this piece) was overheard by our hosts who were seen smirking, language clearly not being a barrier to this double entendre.
