Help troubleshooting Chrome issue causing site not to load completely

Hi Folks,

I am struggling to find the cause of an issue on the following website - http://northwestexpress.co.uk

The issue is that specifically on Chrome the site stops loading before everything is loaded and you can't scroll down the page.

I have had a look and can't find an obvious cause like a plugin or anything. Could you help me find the cause so I can hopefully fix the issue?

Thank you very much for your help.

Cheers,
Kyle
