Обмежувачі навантаження та обмежувачі моменту завантаження колективно називають пристроями захисту перевантаження. Overloading is one of the primary causes of crane accidents. У легких випадках, overloading can damage crane components, спричиняючи перевантаження двигуна та структурну деформацію. У важких випадках, це може призвести до зламаних балків, Колапс вежі, переломи руки, or even complete machine […]

When lifting heavy objects, the hook wire rope should remain vertical. It is not allowed to drag the lifted object diagonally. When lifting heavy objects, the center of gravity should be accurately located and the object should be firmly bound. If there are sharp corners, they should be padded with wooden blocks. Before the heavy […]

(1) The deviation of the position of the girder center line from the designed positioning axis shall not be greater than 5 мм. The alignment of the girder’s center line is crucial as it serves as the central axis for the entire crane structure. Even a minor deviation exceeding 5 mm can cause misalignment of […]

(1) The deviation of the actual centerline of the track from the actual centerline of the crane girder shall not be greater than 10 мм. Precise alignment of these centerlines is fundamental. In large industrial workshops where cranes operate continuously, any misalignment here can lead to uneven stress distribution on the crane structure during movement. […]
