3.Make sure inner facing is long enough in order to avoid pulling at placket bottom.
4.King-sized lifting sling is the high load component in the procedue of lifting weighing 2 395 kg. Its processing quality can directly affect derrick′s successful setching up.
5.A crane-vehicle scheduling model is suggested in a loading container process with a fleet of vehicles, several yard-cranes and a quay-crane.
6.The model is to plan quay-crane loading operation, to schedule yard-crane routing and to dispatch vehicles to containers, so as to minimize the totally idle time of the related equipment and yard-crane travel time.
7.It builds a physical model according to hoisting capacity, lifting angle and structural stabiliy, theory, solves the problem of function relationships among lifting capacity, lifting angle, boom weight, boom dimension and deduces the natural boundary condition of design parameters, providing a new way to determine crane design parameters.
8.A helicopter lowered a paramedic, who attached Nancy to a life-support hoist.
9.During cantilever construction of large span cable-stayed bridge steel box girder, the local relative deformation of steel box girder is obviously different between girder to be suspended and girder supporting crane.
10.A dovetailed iron tenon made of several parts and designed to fit into a dovetail mortise in a large stone so that it can be lifted by a hoisting apparatus.
