Manufacturer Manitowoc Cranes has revealed the Grove GRT8120 rough terrain crane.
The latest model in the GRT series will be on display at the ConExpo 2020 construction exhibition in Las Vegas, USA, from 10 to 14 March 2020. Capacity is given by the manufacturer as 120 US tons or 120 metric tonnes and the preliminary chart shows capacity as 240,000 pounds (109 tonnes) at an 8 foot (2.4 metre) radius with the boom set at 37.2 feet (11.4 metres) long.
Manitowoc said the GRT8120 has the longest boom – 197 feet (60 metres) – and strongest load charts in its class. It is a Megaform boom with Twinlock pinning system. Target markets include petrochemical, construction and wind power industries. Maximum tip height is 265 feet (80.8 metres) with the 57.6 foot (17.6 metre) bi-fold swingaway extension. It is available with manual or hydraulic offset.
Commenting on the new crane John Bair, rough terrain cranes product manager at Manitowoc, said, “Many of our customers wanted to fill a void in the 120 US ton class, and also increase their crane utilisation with easier transportability, greater reach and capacity, and improved access for serviceability.” he said. “We were able to accomplish this through an all-new carrier design along with several other new features debuting on this crane. We’re happy to say that the 197-foot boom length and strong load charts put this crane at the top of its class.”
New on the GRT8120 is the Maxbase asymmetrical outrigger system. It also has a new wider cab with 20 degree tilt. The Boom Configurator mode is used to simplify telescoping the boom and offers on-board lift planning. Improvements over previous models include increased storage and better access for servicing.
