I always wondered why they seem to be on a steep slope too… doesn’t that making getting cages on and off a nightmare?
I do taillift work with heavy items (200kg) and I always park as flat as I can so I’m not either Trying to stop something rolling out the back or pushing it up a slope.
I delivered milk to Aldi’s for a few years & the slopes were certainly a challenge with the milk trolleys. If you didn’t plan ahead you would have the whole load coming at you as soon as you took the bar off.
The slope isn’t a problem for the Aldi drivers with their electric pallet trucks though, which is who it’s designed for. The few Aldi’s that don’t have slopes have a scissor lift instead, which slows you down considerably & if it breaks your knackered.
