A suitable overhead beam should be designed for the open hopper with single-row sludge gate. The advantages and disadvantages of several overhead beam structures are analyzed and compared from the rule requirements, design loads, transverse strength, and the influence on the cabin capacity, hopper weight and dredging operation. The selection of the overhead beam structure is also discussed for the medium-scale dredger with a single-row sludge gate. The analysis method and the selection of each scheme can provide reference for the structural design of the hopper in the dredger.
