Grove GMK6250-L Specifications

The Grove GMK6250-L is the North American designation of the GMK6220-L model AT, which was in production until the end of 2011. This model crane was introduced in 2001, along with the short-boom model GMK6220. The "L" designation denotes a longer boom to avoid having to use a jib extension in most typical jobs for this crane class. This crane offers a main boom of length 72 m (236'), which is quite impressive.  It can easily build tower cranes and various types of wind turbine power stations. Manitowoc now offers the GMK6300L with an 80 m (263') main boom.
