Kroll Cranes Operator’s and Maintenance Manuals PDF

In the first half of the 1980s, the Danish company Krøll Cranes produced 15 giant Kroll K-10000 tower cranes. 13 of them were sold to the USSR, and the remaining pair to the USA. These unique mechanisms (actually two cranes in one) had a lifting capacity of 240 tons (in a modified version - 360 tons), a height of 130 meters and a main boom of 80 meters.

The KROLL K-10000 has proudly borne the name of the tallest tower crane in the world for over forty years. The standard model is 122 m high, equipped with an 81-meter boom, and can lift and carry 120 tons within a radius of 82 m. The model equipped with a long boom can lift 94 tons and work within a radius of 100 m.

The K-10000 can rotate 360 degrees, but must be very well secured. It is secured with huge bolts (164 in total) to a concrete foundation with a diameter of 15 m and a pile depth of 13 m. After that, the K-10000 works with a coverage area of approximately 6 football fields.

To balance the crane, a system of three counterweights is used, one fixed and two on mobile carts, weighing 100 tons. Under such a mount, the crane can withstand wind speeds of up to 280 km / h.

To transport such a crane from Copenhagen to Canada in 2007, 78 containers were used. All mast and boom sections were assembled using a Liebherr LR 1160 crawler unit and an LTM 1080 mobile crane. Three crawler monsters were used for the main assembly work: two Liebherr LR 1300 and a Demag CC 2800. After the tower was erected, the boom was assembled piece by piece by a repair crane at the top.

A total of 15 K-10000s were manufactured from 1976 to 1980 for the construction of nuclear power plants.

In the 2000s, they were sold to China, Singapore and Taiwan.

As of early 2010, nine K-10000s were installed in Asian countries, one in Canada and one in the USA.
