An alternative boom design and welding technique to minimize energy consumption during boom production [PDF]
Scientia Iranica, 2017 This paper presents an alternative boom design for mobile cranes and a method to produce it for minimizing the energy consumption during its production. The main change in the production of the crane booms is the shape of the booms. Normally two symmetric boom parts are manufactured and then these parts are welded by two welding processes, in the ...
