Grove GMK6250 - Wagenborg Nedlift
The Grove GMK6250, a 6 axle 250 tonne crane, of Wagenborg Nedlift from Hengelo (NL) by the assembly of precast concrete parts in Opperdoes (NL). Some days before stood the Liebherr LTM 1250/1 of Van Marwijk here also.
The undercarriage is powered by a Mercedes-Benz OM 502 LA, an 8 cylinder dieselengine with 571 hp. 4 of the 6 axles are driven, alle axles are steerable. The crane's year of manufacture is 1998.
The outrigger base measures 8.7 x 8.5, or half 8.7 x 6 meters.
The crane was used here with 80 tonnes of counterweight, that can be extendes by two hang-on slabs with each 10 tonnes to 100 tonnes. The counterweight has a 5.58 meter tailswing.
The main boom has a 15.5 meter base length and extends up to a 60 meter length. The main boom can be extended by a 51 meter fixed jib or a 61 meter luffing jib.
The superstructure is powered by a Mercedes-Benz OM 906 LA, a 6 cylinder diesel engine with 258 hp. The engine powers 4 hydraulic pumps that operate the crane functions.
The crane is lifting here concrete beams for a new bridge. The main boom is extended 44 meters here.
The first parts of the counterweight (50 tonnes) and the outrigger pads are transported by a DAF XF 105.510 with 6 axle Nooteboom semi low loader.
This crane is actually not used by Wagenborg Nedlift anymore because the crane was sold.
