The invention provides a 3000t crane ship crane load test method, which comprises the following steps of: 1, determining that the maximum weight of a 3000t crane load test is 1.1 times of a rated load; 2, two square barges with the total weight exceeding 3300 t after full stowage are selected, each square barge comprises a plurality of ballast tanks, one square barge is a large square barge, and the other square barge is a small square barge; thirdly, the empty large barge and the empty small barge are transferred to a crane ship; 4, water with different volumes is selected to be pumped in, so that the weight of the square barge hoisted by the 3000t crane reaches the weight of twelve working conditions of a 3000t crane load test, and the square barge is hoisted through a large square barge sling and a small square barge sling which are used for hoisting a large square barge and a small square barge respectively on the 3000t crane; and 5, after the 3000t crane load test is completed, water in the small barge and the large square barge is emptied, and the small barge and the large square barge are hoisted off the ship through the 3000t crane for the test. According to the invention, the effects of reducing the test cost and improving the test safety are achieved.
本发明提供了一种3000t起重船吊机负荷试验方法,包括如下步骤,步骤一:确定3000t吊机负荷试验最大重量为额定载荷的1.1倍;步骤二:选择两个在满配载后总重量超过3300t的方驳,方驳内均包含若干数量的压载舱,且其中一个为大方驳,另一个为小方驳;步骤三:将空的大方驳和小方驳转运至起重船上;步骤四:选择抽入不同体积的水,使得3000t吊机所吊装的方驳的重量达到3000t吊机负荷试验的十二个工况的重量,并通过3000t吊机上分别用于吊装大方驳和小方驳的大方驳吊索具和小方驳吊索具进行方驳的吊装;步骤五:在完成3000t吊机负荷试验后,将小方驳和大方驳内的水排空,并通过试验用的3000t吊机将小方驳和大方驳吊装下船。本发明产生了降低试验成本提高试验安全性的效果。
