The VNA choice can make or break a warehouse in my opinion.
The Crown is a solid machine mechanically (except excessive chain & mast roller wear), but it's software is problematic & overcomplicated, the ones that we ran were forever pushing fault codes, affecting productivity by 20% on some shifts by having to constantly restart the truck, apparently it was us the customer at fault according to Crown!, despite a Linde we also had on site running rings around it doing same job.
Tyres are stupidly expensive, 3 times the cost of any other VNA we ran from Linde & Yale, plus service cover in the UK is appalling bad (not sure what Canada is like) , but with it being pushed as a vertically integrated global company (don't you just love sales folk) I thought all would be good, got better service from the local independent on these.
I was glad we had a break clause in at 3 years on these things, so ended the contract.
The Yale machines were a bit old school in tech, but better for it, service was excellent too & parts were always in stock, some issues on residual capacities at max height on Yales, but it was a minor inconvenience to be fair.
We also ran Linde K trucks VNA, good machine, but made of cheese if it collided with anything, end of contract costs were high on the Lindes because of this and bits tended to fall off it for some reason.
The Yales were and still are a good machine, probably 80% of our fleet VNA are Yale now.
