Trio of Grove GMKs form backbone of Swiss logistics company’s new premises

  • Emil Egger AG has purchased a GMK6300L-1, a GMK5250L and a GMK5150L from Stirnimann AG to operate out of the company’s new premises

  • The three mobile cranes were chosen due to their long telescopic booms, high load capacities and strong drivetrains – ideal for the erection of tower cranes

  • Swiss transport, heavy lift and warehouse logistics company Emil Egger AG has purchased three new Grove mobile cranes to form the backbone of its new facility in Bassersdorf, near Zurich.

Headquartered in St. Gallen, Switzerland, Emil Egger AG is an established mobile crane hire company for the construction industry, specializing in complex projects in heavy lift logistics and the erection of tower cranes. The three cranes were supplied by Stirnimann AG and comprise one GMK6300L-1, one GMK5250L and one GMK5150L.


“When choosing the new mobile cranes, the most important factors for us were long telescopic booms, high load capacities and a strong drivetrain,” says Michael Egger, managing director of Emil Egger AG.  “From our point of view, the new GMK6300L-1 is the best in its class and the GMK5250L and GMK5150L are also very powerful and compact cranes. With the new models, we can do most jobs in two to four hours. Doing away with additional auxiliary cranes alone shortens assembly and dismantling times by at least two to three hours. This not only reduces the disturbance around the construction site enormously, but also the costs. As a result, we can offer reduced pricing, making is even more attractive to customers.”

A powerful trio

The 80 m main boom of the GMK6300L-1 can carry a load of up to 14 t at full height, with a working radius of 14-28 m. The powerful yet fuel-efficient 430-kW (580-HP) Mercedes-Benz engine (Euromot 4/EPA Tier 4 final) in the carrier is combined with a reliable Allison torque converter transmission and provides for wear-free starting in confined and mountainous areas. The superstructure is powered by a Mercedes Benz engine (Euromot 4/EPA Tier 4 final) with an output of 210 kW (280 HP).

With the GMK5250L, Emil Egger now also has one of the strongest and most versatile five-axle cranes on the mobile crane market. With its 70 m main boom and 250 t payload and fast set-up times, it is also ideal for erecting and dismantling tower cranes. The new VIAB turbo clutch ensures particularly good manoeuvrability and high driving comfort, and the turbo coupling module prevents the clutch from overheating.

With a load capacity of 150 t and its 60-m-long main boom and a taxi ballast of 10.2 t within 12 t per axle, the compact GMK5150L is an excellent taxi crane and does not require an additional accessory vehicle for most jobs.

Strong support

“In addition to the convincing performance of the cranes, the technical support provided by Stirnimann AG was also a strong benefit of purchasing the cranes,” adds Egger. “Although we maintain our own workshop for the maintenance of our cranes, we are very grateful for the fast and competent help from Stirnimann. Because of this, lengthy periods of downtime have so far been avoided.”
