once went to a shopping mall indevon some where i was delivering dranage pipes to a job in the car park,when i got there the in barrier was up so i went in deliverd the said pipes came out pressed button to speak to the attendent he pressed his little button and let me out i got the tractor unit out but the trailer got stuck on the posts just like the car in the video but only lifted the trailer about 6 inces off the floor before it came to a grinding halt and a very irate attendent came running out of his office ooooops
anyway no harm done to the trailer but the hydrolics to the posts needed sorting
