Multivariate calculation of the lifting mechanism of a bridge-type crane on a computer [PDF]
Научно-технический вестник Брянского государственного университета, 2023 The mechanism for lifting the load of bridge-type cranes, as a rule, is placed on a cargo trolley moving along the crane bridge. The weight of the cargo trolley and the weight of the load create a bending moment on the bridge.
