The Group

Heavy Lift max. capacity 416 t

Job Report

Situation

The MTC 78000 is one of the largest offshore slewing cranes

world-wide. With a maximum dynamic torque of 78,000 mT, the

MTC 78000 is the most powerful machine within the extensive

range of cranes and material handling equipment offered by the

Liebherr group of companies.

Task

The onsite erection and assembly of this enormous crane on

the heavy load vessel OSA Goliath presented Liebherr engineers

with special challenges – for example, the planning of the indivi-

dual hoists so that the maximum permitted ground pressure of

the pier was not exceeded.

Solution

Two LHM 600 mobile harbour cranes were used in tandem oper-

ation for the heavy duty lifts. Sycratronic

allows two LHM 600s

to lift up to 416 t and to be operated simultaneously by one

crane driver. Conventional, manually-operated tandem lifts with

land-based cranes need to comply with international standards,

resulting in load capacity down rating of 25% and more.

Performance

The assembly of the MTC 78000 required several spectacular

heavy duty lifts. First, the slewing platform, weighing 370 t, was

mounted, thereafter, the machinery compartment with the drive

components (approximately 240 t), the mast lower section (about

250 t) and the mast upper section (around 160 t). The hoisting

height of 43 m above pier level was made possible by equipping

the mobile harbour cranes with two corresponding tower exten-

sions.
