| Manitowoc innovative new mobile crane, Grove GSK55  Manitowoc will introduce an innovative new mobile crane in early 2009 that combines the lift ability of Grove all-terrain cranes with the flexibility and mobility of a standard on-road truck. The GSK55 merges the upperworks from Grove's GMK3055 all-terrain crane with a specially-designed truck chassis that acts as a trailer. The customer can use the tractor of their choice to haul the crane to jobsites. The truck chassis has its own 93 kW Iveco engine that provides full power to the GSK55, operating all the crane's functions, including the outriggers. Because of its standard design, the crane does not need to be tied to any one brand of tractor. This is a useful benefit if the crane is working at a job site where multiple trucks are in operation or for customers that operate fleets of trucks. The ability to attach any tractor also means that national requirements for left-hand or right-hand vehicles are easily accommodated. Because of its configuration the crane can offer favorable axle loads for travel. With two axles on the tractor and three on the trailer, loadings do not exceed 9 t on any single axle when the crane is traveling with its maximum counterweight of 11.6 t. This axle load of 9 t is well below the 12 t per axle maximum in many markets. Lifting specifications for the crane match the GMK3055, so maximum capacity is 55 t and it has a 43 m main boom. An optional 8.7 m/15 m swingaway jib is available, giving a maximum tip height of 60 m. write your comments about the article :: © 2009 Construction News :: home page |
