Tadano GR700EX-4

The GR-700EX-4 is rated at three metres and features a five section 47 metre rounded profile main boom which utilises two telescope cylinders, one which extends section two – the first telescopic section – while the other three sections are fully synchronised with ropes and sheaves. The boom is topped by a 10.1 to 17.7 metre bi-fold swingaway extension which offsets by up to 45 degrees and offers a maximum tip height of just under 68 metres. The crane has 4.35 tonne integrated counterweight.
