Blackburn & Roberts | A Day in the Life of an Engineer
There are three kinds of Engineers. Those that make things happen, those who watch things happen and those who wonder “What the hell happened?”.
They like to think they reside in the first group.
Bridges have agreed standards for loading defined by Euro Codes. These differ with the user type and frequency.
For example a Bridleway Bridge is designed to have a uniform loading all over the deck at the same time but the deck is also designed to be able to carry the concentrated load of the large horse, rearing up on its back legs then putting all its weight onto a single hoof.
Blackburn & Roberts supply many Game Parks and private clients with unique, species-specific Cattle Grids and continue to enjoy excellent relationships with these clients and their charges.
Standing next to a giraffe and having it lower its head (nose to nose) and having it look you in the eyes is a truly memorable experience.
Sadly they were obliged to decline a bridge in the lion enclosure at Chester Zoo as our erectors have an unreasonable, morbid, dread of being eaten alive.
A recent commission for a member of the Merlin Family required them to design a Rhinoceros Bridge. The size of these beasts is well known, and it is impressive, but I wonder how many readers know if it is physically possible for a Rhinocerous to stand on one back leg!
