Nuclear Power
Te drive for the LR 13000 makes use of two Liebherr V8 diesel engines, producing a total power rating of 1000kW/1360hp. Tese are designed in a redundant format in order to increase crane availability still further.
Te cables have some impressive dimensions too. 52mm thick, a total length on each hoisting winch of about 2000m, and a line pull of 62t. To guarantee maximum operational reliability and ensure easy maintenance, all the winches are driven by several independent motors on an internal gearing of the cable drum. Tis means that the crane can continue working even if a drive unit breaks down, and the unit can be replaced rapidly and easily. Te hook block weighs 111t and is 9.7m high, for lifting up to 3000t. It is of modular design and consists of a maximum of two hooks and six pulley sets, with five pulleys each. It can be configured easily for different operational purposes.
Te LR 13000 has a large number of ladders, platforms, and catwalks, with all appropriate guardrails, provided for best possible safe access during the assembly and operation of the crane. ●
Fig. 2. The crane’s cables are 52mm thick, have a total length on each hoisting winch of about 2000m, and a line pull of 62t.
And when it came to the boom design, economical transport logistics were again a key issue. Tis meant, for example, that for transport the intermediate elements of the luffing fly jib are pushed into the intermediate elements of the main boom with the aid of rollers.
