Grove launches 60m boom GMK4070L

To strengthen its four-axle all-terrain crane line-up, Grove unveiled the GMK4070L at bauma. The 70t capacity GMK4070L offers the strongest load charts and the longest boom in its class at 60m. At its full 60m length the crane is able to lift an impressive 4.4t, while at 49m owners will be capable of picking loads of up to 8.3t. When working at its maximum radius of 46m, the GMK4070L will lift 1t.

Up to 78m of maximum tip height is available when the 60 m main boom is paired with its 15 m swingaway jib option. These are capabilities more commonly associated with 100t cranes and allow the new model to take on jobs that would typically require larger cranes.

“The Grove GMK4070L offers improved engineering design and adopts several latest technologies to deliver a new level of performance, operation, serviceability, and fuel efficiency,” said Andreas Cremer, vice president of product management for mobile cranes at Manitowoc. “It’s a crane that will be a true game changer, surprising many customers with just how much more a 70 t all-terrain crane can achieve.”

One for the road

Offering unmatched versatility, the GMK4070L will give owners a host of options for travel. At a configuration of 16.5t per axle, the crane will carry an impressive 17.8t of counterweight, just shy of its full 19t complement. In situations requiring 12t per axle, it will carry up to 13.3 t, while at 45.8t for NSW Level 4 GVM, it will be able to travel with 11t of counterweight while for 10t per axle configurations it will be able to travel with 5.3t of counterweight. 

A Telma retarder packaged in the carrier design will reduce the risk of overheating and overall wear and tear on the conventional service brake system. The frictionless, maintenance-free Telma braking system remains effective even after the engine is switched off, or when the gearbox is in neutral, ensuring full braking power is available, regardless of the crane’s speed.

The new high-visibility carrier cab offers the best levels of protection in line with European ECE R29-3 regulations, ensuring exceptional security in frontal impact, roof, and rear wall strength. Power for both the carrier and the superstructure will come from a single 320 kW (430 HP) Mercedes Benz OM470LA 6-cylinder diesel engine. Compliant with Euromot 5/Tier 4 Final requirements, this clean, efficient engine is approved for use with HVO Diesel, for customers looking to further reduce their CO2 emissions or meet tight environmental jobsite requirements. The engine’s ECO mode can be used in conjunction with the transmission’s Fuel Saver mode, for unbeatable fuel efficiency.

Technology and automation
to the fore

The GMK4070L will be one of the first Manitowoc cranes to offer the exciting new Grove CONNECT™ digital platform that provides owners with real-time access to fleet data. Through Grove CONNECT™, fleet managers can get instant insights into the crane’s performance with just a couple of taps on a screen. Service technicians are supported with remote, optimized troubleshooting, reducing the frequency of onsite trips and strengthening preventative maintenance programs.

The optional MAXbase feature helps users reduce setup time at the jobsite and give them a wider choice of outrigger positions. With this option, the crane becomes an ideal choice for confined spaces or projects where obstacles are preventing setup in the preferred location. The productivity-enhancing MAXbase allows the crane’s four double hydraulically telescoping outriggers to be easily extended to a range of symmetric and asymmetric positions. This maximizes flexibility and enables lifting work to continue in less-than-ideal environments.

Also making life easier for the operator is Manitowoc’s Crane Control System (CCS), which supports both setup and lifting. Using its Boom Configurator feature, the operator can select the optimal arrangement of the seven-section MEGAFORM® boom with TWIN-LOCK® dual-pinning system.
