ROUGH TERRAIN CRANES Ӏ SECTOR SPOTLIGHT
AMHEC was formed in
2007. It is based in Khobar and provides crane rentals, heavy lifting, transportation, and rig move services across the kingdom. Its crane fleet exceeds 400, many of which are Tadano models.
NEW ERA US manufacturer Manitowoc showed its latest rough terrain, the 55 ton capacity GRT550, at Bauma. The company describes the crane, which is being manufactured at the Grove factory in Niella Tanaro, Italy, as ‘marking a new era of high-performing rough-terrain cranes. The GRT550 succeeds the
Grove RT550E. It has a five- section boom with Twin-Lock and Mega-Form and a 39m reach. A tip height of 49m is possible with the 8m offsettable swingaway
extension. Maximum capacity is 50t and there are overall load chart improvements over the RT550. The GRT550 also offers a line pull of up to 5,552kg – an increase from the 5,100kg offered by the RT550E. In addition, it requires less line, speeding up rigging time. A a maximum line speed of 155m/ min is possible. The new crane has a GVW

below two tonnes allowing for road transport across Europe without permitting. It is also compact (6.9m long by 2.55m wide). It has Site Steering mode, to aid handling, plus an updated outrigger system which facilitates smart monitoring of the single- stage outrigger beams. It also offers Grove’s MAXbase variable- position outrigger system. The GRT550 has a new cab with high-capacity HVAC. Visibility has
been improved, says Manitowoc, particularly to the boom and a three-camera system is available as an option. The cab includes an adjustable heated seat with armrest-mounted joystick controls and a new 12-inch CCS 1+ touchscreen display. Power comes from a proven and
reliable Cummins QSB6.7 engine which has an ECO mode for even higher fuel efficiency. “Retaining features such as
remote-mounted filters and centrally located service points shows just how technician-friendly the GRT550 is,” said Daniele Montanaro, product manager for rough-terrain cranes at Manitowoc. “And we’ve added advanced service and diagnostics features such as the Grove Connect fleet management system and our On Crane Service Interface (oCSI). All are designed to make the technician’s job much easier, while uptime reaches new highs – exactly what owners are seeking in a powerful RT crane that’s capable of tackling all general handling and maintenance jobs.” The crane on Manitowoc’s stand had been bought by Polish crane rental company Petrolift. Next to the GRT550 at Bauma was another of Manitowoc’s latest Grove RTs: the 80 ton Grove GRT780 – which made its European and trade show debuts at the event. The one on display had been bought by Italian crane rental firm OMEC.
The crane will replace Grove’s
RT770E and GRT880. The new model is currently built in Shady Grove, Pennsylvania, although it will also soon be manufactured in Niella Tanaro, Italy, to better serve European and emerging markets. The crane has a five-section
Megaform full-power boom spanning 11.9–47.3m. At full extension, it can handle loads of up to 8.16t at working radii
