Manitowoc has announced a new Grove all-terrain crane for the global market and it offers several unique innovations and class-leading capabilities. The 250 t capacity Grove GMK5250L has the strongest reach and load chart of any five-axle crane. It also offers the best manoeuverability and class-leading driver comfort, which it delivers thanks to its inclusion of a VIAB turbo clutch and integrated retarder - the first ever mobile crane to feature the system.
The VIAB turbo clutch module eliminates both fluid overheating and clutch burning, while enabling wear-free starting and braking. It also contributes to fuel savings and on the GMK5250L fuel consumption is estimated at approximately 30 per cent below that of its predecessor, the GMK5220.
The “L” designation for the GMK5250L indicates it is a long boom all-terrain crane, and in this case the main boom is an impressive 70 m, which also includes Grove-¦s Megaform shaping for better strength and stability. With its long boom length, the GMK5250L can offer more reach both vertically and horizontally than any crane in its class, allowing owners to take on a greater range of jobs with the crane.
Boosting overall reach is a 21 m hydraulic swing-away jib, which can be extended with either an 8 m boom extension, two 8 m jib inserts, or a combination of both for a total possible jib length of 37 m. For optimum usage, the full jib can also be operated while the crane is working with its full 70 m boom length extended.
