no love for bubbles for the guys/girls that have to maintain and operate them. lots of articulating parts and cables that need adjustment to keep them open / closed at the right position, maintenance checks / repairs on these components, maintenance / repairs / timing on the auto-closers and openers. dealing with graffiti and vandalism on the bubbles. due to the effective area of bubbles when in the "up" position, the lift is down even in a little puff of wind due to carrier swing if the unload station auto closer is fubar. rope evac techniques must be modified and presented/demonstrated for the lift inspector, how many patrollers are qualified for this task are on-hand every day? especially summer ops, with both uphill and downhill loaded. not a fan from the ops perspective.
