The documents show that the, previously secret, GCK 3045 will lift up to 45t. The three axle all terrain will feature a 34m six extension boom, with a maximum tip height of 36.5m. An optional 6.3m–10.2m twist jib will increase the crane’s maximum system length to 47m. The jib can be offset at 5°, 25° and 45°.
The new crane will be powered by a single HINO E 13 C engine, delivering power over a hydro-static transmission. The hydraulic system’s five variable displacement axial piston pumps (3 x drive, 2 x lift, derrick, telescoping and outriggers) will allow five simultaneous functions.
The GSK55 product presentation lays out how Manitowoc’s dealers are pitching the new crane against Terex’s PPM TC 60, Tadano Faun’s HK60 and Liebherr’s LTF 1045 4.1. According to the document, one of the key selling points of the new crane is the ‘strength and reach’ of the main boom. The six section boom will extend to 43m, almost 3m more than the closest competitor in this capacity class, Manitowoc claims.
The company is also inviting potential customers to compare the GSK55’s turning radius to rival products. The company says, “The truck and trailer concept allows big advantages on tailswing (up to 3.5m) and turning radius over boom and jib (benefit: 2m minimum).”
Other advantages the company claims for the GSK55 are reduced overall travelling height, ‘very good’ roadability, and ‘very low running costs’. Graphs included in the document show the GSK55 performing reasonably well against its competitors in terms of maximum available counterweight in particular configurations.
The final page of the document details the key advantages of the GSK55 against its three competitors. Against the PPM TC60, Manitowoc will highlight the Terex crane’s single engine and lack of a commercial chassis. The GSK55, Manitowoc claims, has a better turning radius and height than the PPM TC60.
When dealers compare the new crane to the LTF 1045, they will point out that the Liebherr only supplies the crane superstructure, meaning the customer needs two finance contracts. They will boast that the Grove has full counterweight on board, better loadcharts and a longer boom than both the Liebherr and the Tadano Faun HK60.
