Grove GMK5250L

The Grove GMK5250L is a high-capacity 250-ton all-terrain crane, engineered for exceptional lifting power, efficiency, and transportability. With its five-axle carrier and a class-leading 70-meter (230-foot) main boom, the GMK5250L is an industry leader in long-reach applications, reducing the need for jib attachments in many lifting operations. When additional reach is required, a lattice jib system extends the maximum system length to 110 meters (360.9 feet), allowing the crane to handle high-elevation lifts with ease.

One of the key innovations in the GMK5250L is its VIAB turbo clutch and retarder, making it the first all-terrain crane to feature this system. The VIAB unit improves fuel efficiency, enhances acceleration, and minimizes wear on the braking system, reducing overall operating costs. The Mercedes-Benz OM471LA six-cylinder diesel engine, producing 390 kW (523 hp) and 2,460 Nm of torque, ensures strong on-road performance and excellent off-road capability. Paired with an Allison automatic transmission, the crane provides smooth shifting and easy maneuverability on highways and job sites.

The MEGATRAK™ independent hydro-pneumatic suspension system allows for all-wheel drive and all-wheel steering, significantly improving mobility on rough terrain and tight job sites. With a compact width of just 3 meters (9.8 feet) and a tight turning radius of 8.6 meters (28.2 feet), the GMK5250L is one of the most compact five-axle cranes, making it highly maneuverable even in confined spaces.

For lifting precision and safety, the GMK5250L is equipped with Grove’s Crane Control System (CCS), which provides customizable load charts, real-time diagnostics, and user-friendly operation. The twin hoist system allows for high-speed lifting, while the slewing system provides smooth 360-degree rotation, ensuring accurate load handling.

The outrigger system offers multiple extension positions, enhancing lifting stability on uneven ground conditions. Additionally, the MAXbase asymmetrical outrigger positioning system allows for optimized load charts in restricted spaces, increasing flexibility and efficiency in urban construction sites.

Inside the operator’s cab, the GMK5250L features an ergonomic design with a touchscreen display, joystick controls, and a comfortable air-conditioned environment, ensuring operator comfort and precision control for extended work periods.

With its exceptionally long boom, innovative drivetrain, compact five-axle design, and state-of-the-art control system, the Grove GMK5250L is one of the most advanced and efficient all-terrain cranes, offering outstanding lifting capabilities, fuel efficiency, and job site adaptability for demanding lifting applications.
