Liebherr MK 88 - Tieman
In 2018 took Tieman from Schagen (NL) this sharp Liebherr MK 88 in Plus version into operation. It is a 4-axle mobile tower crane with a maximum load moment of 90 mt.
In transit is the crane 15.94 meters long, 2.75 meters wide and 4 meters tall. The transport mass is approx. 48 tonnes. The 4-axle undercarriage is powered by a Liebherr D936 A7, a 6-cylinder diesel engine with a power of 300 kW (408 hp). The axles 2, 3 and 4 are driven and all axles are steerable.
The outrigger base of the crane measures 7.3 x 7 meters, or half 7.3 x 5.75 meters.
Here was the crane used on a construction site in Schagen (NL) to lift roof plates onto the steel construction.
At the rear of the chassis are storage comapartments and a large platform installed to bring additional lifting gear.
It is the MK 88 in "Plus" execution, mainly recognizable on the additional 2 tonnes of counterweight. By using the additional "Plus" load curve are the dynamic back-ups used by reducing the working speeds of the drives, because of that the crane can lift more.
The cabin at the superstructure can be moved by use of a winch in height along the tower to give the crane operator a proper view on the works.
The jib has a max. length of 45 meters. The crane can lift a maximum load of 8 tonnes up to a 13 meter radius and 2.2 tonnes up to 45 meters. The jib is easy adjustable to a 15, 30 or 45 degree angle.
A very sharp crane by Tieman!
