Grove is responding to customer demand for a higher-capacity all-terrain crane by introducing the Grove GMK6450-1.
The GMK6400-1 will be upgraded to the new GMK6450-1 and carry an increased maximum capacity rating of 450 tonnes, which is 50 tonnes more than its predecessor. The crane remains the strongest all-terrain crane available on six-axles and renaming it better reflects its capabilities.
“Over the past two years, we have seen a growing demand for a name change from our global customer base. We reviewed the crane’s performance, which resulted in a new model, the GMK6450-1,” said Andreas Cremer, Vice President Product and Project Management for Mobile Cranes at Manitowoc.
The addition of the MAXbase variable outrigger positioning system on the GMK6400-1 in 2021 allowed customers to further capitalize on the all-terrain crane’s strong performance. This feature allows the use of asymmetrical outrigger setups and results in enhanced load charts. In addition, MAXbase can be used in conjunction with the capacity-increasing MegaWingLift. The self-rigging attachment can be deployed in less than 20 minutes and does not require an assist crane.

MAXbase increases lifting capacity by up to 70 per cent on the main boom and by up to 400 per cent when using the luffing jib. These enhancements led to customer requests for renaming the crane.
The Grove GMK6450-1 offers segment-leading lifting capabilities and has been used on projects in place of seven-axle – or even eight-axle – all-terrain cranes.
For example, it can lift 8.9 tonnes between 38 metres and 50 metres radii when working with its full boom and jib system length of 136 metres. When working with 120 metres of boom and jib, the crane handles 12.8 tonnes at distances between 36 metres and 52 metres.
Furthermore, the GMK6450-1 is particularly well suited to wind power projects that require flexible set-up distances to the turbine and the ability to lift heavy loads at steep vertical angles. It can lift in wind speeds of up to 9 m/s with its 79 metres luffing jib.
