MHWirth has given the thesis of designing a new lifting yoke as a multidisciplinary project. The new yoke is required to lift more than the parallel yoke currently supplied by the company. The necessary instrumentation and hydraulic components to operate it safely and efficiently is required. A cost estimation from both disciplines on the yoke parts will be done. The project group has through a concept phase, designed a new lifting yoke approved by the company. The design is based on a design of a pallet fork. In the pre-engineering phase the group was divided into the respective disciplines. A complete mechanical design and a hydraulic system have been developed, along with a through selection of electrical components. The hydraulic system, together with the mechanical movements has been analyzed to compare the new yoke with the parallel yoke, in terms of operational efficiency. The new yoke is potentially more efficient than the parallel yoke due to the amount of pipes transported simultaneously. An analysis of
the time used on mechanical movements has shown that the yoke is able to compete on an equal level of efficiency as existing equipment. The new yoke fulfills the requirements of lifting capabilities set
from the company. The project group has done a cost estimation based on NOK/kg, and a supplied parts list for the electrical and hydraulic equipment on the parallel yoke. The total cost of 443 kNOK for the new yoke will act as a recommendation to continue the engineering of the yoke.
