Grove GMK5220 - Emil Egger

A Grove GMK5220 of Emil Egger from St. Gallen (CH) on a construction site in Schaan (LI) to install precast concrete elements for a new building. Emil Egger has (had) two cranes of this type. The piles for this building were driven by the Banut 650 of Kibag.

It is a 220-tonne crane installed on a 5-axle undercarriage. The outrigger base of the crane measures 8.55 x 8.1 meters, or half 8.55 x 5.6 meters.

The undercarriage is powered by a Mercedes-Benz OM 502 LA, an 8-cylinder diesel engine with a power of 420 kW (571 hp). This crane has the optional 10x8x10-drive line where the axles 2 to 5 are driven and all axles are steerable.

At the rear of the chassis is a large box installed for the wooden beams, nothing unusual for cranes in Switzerland to adjust the large height diffrences between the outriggers.

Special is the execution of the counterweight, this is not standard by Grove. Up to 41 tonnes is the tailswing 4.9 meters, to complete the counterweight to 77 tonnes are wider counterweight pieces used and is the tailswing increased to 5.3 meters. With the standard counterweight is the tailswing always 5.3 meters. Here is also the second winch in use.

On the other side was the crane erected on half outrigger base. The superstructure is powered by a Mercedes-Benz OM 906 LA, a 6-cylinder diesel engine with a power of 170 kW (231 hp). The diesel engine poweres in total three hydraulic pumps, to control the crane functions. The upper cab is 20 degrees tiltable.

Packed has the crane a 15.82 meter length, a 3 meter width and a 4 meter height. The transport mass is around 60 tonnes.

The 7-part maing boom has a 13.3 meter base length and extands maximum six times to a full length of 68 meters.

Attached to the main boom head is a fixed short jib that is currently used for a second hook (with the second hoist winch). With two hook operation is it possible to receive loadings like long columns in horizontal position and to rotate them into verital position with help of only one crane.

A sharp crane by Emil Egger!
