Manitowoc’s new Grove GMK5150L and GMK5250L will be shown For the first time in North America at ConExpo 2017, which begins on March 6 in Las Vegas, Nevada.
Both the GMK5150L and GMK5250L possess groundbreaking technologies that aim to generate a higher return on investment for Manitowoc customers. Notably, a single Tier 4 Final engine powers each crane, a concept pioneered by Grove on its highly successful Grove GMK6400. The engine drives both the carrier and superstructure, reducing overall weight and lowering fuel consumption, which leads to lower operating and maintenance costs.
“The GMK5150L and GMK5250L reflect years of technological advancements in Grove all-terrain crane design and engineering,” said Andreas Cremer, Manitowoc’s global product director for all-terrain cranes. “These are workhorse cranes that provide measureable benefits over previous generations of all-terrain cranes.”
The “L” designation for the GMK5150L and GMK5250L denotes the fact that they are both “long boom” models that provide more reach for a variety of applications, such as tower crane assembly, narrow lifts in congested cities or reaching over buildings to complete HVAC projects, among many other examples.
The GMK5250L has an impressive 230ft (70m) boom while the GMK5150L boasts a 197ft (60m) boom. (Grove also offers the GMK5150 with a shorter 167ft (51m) boom and slightly increased load charts.) Megaform shaping and Twin-Lock pinning ensure these hydraulic booms are among the most stable on the market.
The GMK5150L and GMK5250L also feature Manitowoc’s Crane Control System (CCS). The standardized CCS is a user-friendly interface that Manitowoc has introduced on all new all-terrain crane models, as well as crawler cranes, rough-terrain cranes and tower cranes. This makes it easier for fleets to operate and maintain a standardized set of crane controls across several crane types. Its Boom Configurator Mode is especially useful, making it quick and easy for operators to select optimum boom positions for lifts.
