Compared with the head-grabbing machine, Screw ship unloader's salient features are summarized by two guarantees. One is to ensure that the cargo is not polluted by the environment, and the other is that the cargo does not pollute the environment. Other features are continuous material processing, high equipment automation, small work area, and environmental protection.
1. Before boarding the Screw ship unloader, check the walking track and moving range of the Screw ship unloader for operators and obstacles; check whether the anchoring device, anti-climbing iron wedge, wind-proof cable and wheel clamp are complete, If it is intact, the anchoring device, wind-proof cable, and anti-climbing iron wedge should be removed to make it in a non-anchored state.
2. For boarding of the transfer shift, the Screw ship unloader should be checked and confirmed along the boarding route. Check whether the main cable is twisted, injured, or loose at the fixed location; check whether the funnel system is intact; check the condition of the grab connector and the wear of the grab wire rope, and report any abnormalities in time.
3. Check whether the wire rope and wire rope joints are normal; if there is looseness, tighten it.
4. Check the front and rear girders of the Screw ship unloader to confirm whether there are obstacles in the main trolley, the rope trolley track and the moving range, and whether there is any abnormality in the trolley track.
