Recently, the abovementioned construction company of prefabricated steel structures is built a coastal oil module for another firm with a worldwide known name. The full set of tools is presented. Sometimes during the creating of the module, it’s an obligatory to attract heavy lifting masters to safely lift particularly heavy elements & install them on the platform base.
When it’s time to pick up & fix on the top of the module a large cargo traverse used for lifting at sea, the company’s attracted to develop the most efficient & economical solution for the lifting partner of the Sarens company. Modules of a massive scale, which are considered as critical ones of this sphere, reach:
- 25 in height (m)
- 30 in width (m)
- 40 in length (m)
- 2,200 in weight (t).
The correct equipment choice
The traverse’s:
- 13.5 m in length
- 5 m in width
- 6 m in height
- weighs 145 t.
It’d to be raised from the ground level to the installation height of 32 m & during the ascent, the crane’s to operate at a maximum radius of 24 m. As the manager for clients announced, the company considered a whole number of various options: beginning with a single crane and ending with the using of the two cranes that were off-road.
The advantage of the option with one crane’s that it would take only one crane & one team to work. However, the installation of the crawler crane would require several days & more than 20 platforms to transport the crane components needed for its installation & adjustment to provide a load capacity of 145 tons at a radius of 24 m.
Having finished the climb, both teams dismantled the rigging of their cranes & the column with the equipment used during the ascent moved on its way back to the crane depot Sarens. In the used version of the two cranes, the traverse & all the auxiliary equipment were safely & effectively installed on the oil module in just three days – seven days faster than calculated for the version of one crane. This provided an ideal load distribution between the two cranes. More importantly, the variant saved money for the clients of Sarens.
