Goliath crane with 300t lifting capacity

300t/145m goliath crane is applied for hull construction in shipyards (such as ship dock, slipway and so on), which has functions of hoisting up and down, swinging, turnover in the air by sections. The turnover by sections and closure operations are the special features. By means of the turnover operation by sections through two trolleys, the adjustment of hoisting up and down will be made first to have the upper trolley bear the whole sections. The lower trolley with no load will go through the underside of the upper trolley and re-tie on the other side of the section. Finally the 180 degrees turnover operation can be completed by the upper trolley’s hoisting up and down, and the horizontal movement of the upper and lower trolleys.
