<\/figure>\n\n\n\n(1) Crane structure or parts (such as hooks, wire ropes, brakes, safety protection devices, etc.) have defects and damages that affect safe work;<\/p>\n\n\n\n
(2) The hanging object is overloaded or may be overloaded, the weight of the hanging object is unclear, it is buried or frozen in the ground, and it is squeezed by other objects, and it is not allowed to slant it during operation;<\/p>\n\n\n\n
(3) The hanging object is not firmly tied or hanging unstable, and there is no padding between the corners of the heavy object and the sling; there are people or floating objects on the hanging object;<\/p>\n\n\n\n
(4) The work site is dark, and the site, hanging objects or command signals cannot be clearly seen.<\/p>\n\n\n\n
Ninth, when there is a sudden power failure during work, all controllers should be reset to zero, and the main power supply should be turned off. Before restarting work, check whether the crane works normally, and then operate normally after confirming safety.<\/p>\n\n\n\n
Tenth, if there are two sets of main and auxiliary hoisting mechanisms, it is not allowed to use the main and auxiliary hooks to work at the same time (special cranes allowed by the design go out).<\/p>\n\n\n\n
Eleventh, when two or more cranes are used to lift the same heavy object, each crane shall not be overloaded. During the transfer process, the wire rope should be kept vertical and the operation should be synchronized. When hoisting, relevant responsible technicians and safety technicians should be present for guidance.<\/p>\n\n\n\n
Twelfth, rail cranes operating in the open air should stop working when the wind force is greater than level 6; when the work is over, the cranes should be anchored.<\/p>\n","protected":false},"excerpt":{"rendered":"
