The driver of this vehicle collected a fully laden fridge trailer (gross weight 44T). Unfortunately, the pin wasn't engaged and as he turned off the loading bay, the trailer carried on in a straight line. It managed to get beneath the canopy and (luckily) stopped just in front of the canopy's upright. The lifting frame/spreader bar was set up and the was trailer raised and supported whilst it was reconnected. Very little damage was done to neither unit or trailer.
