What a shite ..er
...Actually, If I'm delivering some kit off my 30 tonner, I am very wary of driving over those BT Manhole rectangular covers you see on the pavement, everyone bumps onto the pavement now and again, but they arent built for heavy loads I fear having seen how thick they are, and built from trashy quality concrete, the boat hoist pic is a good example of how tits up, it can go .. bummer
