Abstract

The invention relates to a safety lifting hook and a manufacturing method thereof. A lifting hook is additionally provided with a supporting plate (2); the left end of the supporting plate (2) is connected with a baffle (3) through a pin (4) and a cotter pin (5); a stop pin (6) is arranged on the front lower part of the lifting hook (1); and a move pin (7) is arranged at the lower end of the baffle (3). The manufacturing method of the safety lifting hook comprises the following steps of: a. arranging the supporting plate (2) on one side of the lifting hook (1); b. connecting the supporting plate (2) with the baffle (3) through the pin and the cotter pin (5); c. arranging the stop pin (6) on the front lower part of the lifting hook (1); and d. welding the move pin (7) on the lower end of the baffle. In the invention, an anti-drop safety device is additionally arranged on a standard lifting hook, thus, unhooking does not occur when the lifting hook is crashed with other objects during lifting or lifted objects are chocked by foreign matters when falling to the ground or when a lifted container is turned over, thereby personal safety is guaranteed.

Description

technical field [0001] The invention belongs to a hook on a lifting device, in particular to a safety hook and a manufacturing method thereof. Background technique [0002] At present, the hooks on all lifting equipment are designed and manufactured according to the standard, and generally there is no anti-off safety device. Once it collides with other objects during hoisting or is cushioned by foreign objects when the hoisted object falls to the ground, it may cause unhooking in the air, or the hoisted container will be overturned and unhooked (such as a ladle containing molten metal, etc.), which may cause the If it is broken by hanging objects, people will be injured; or liquid metal, etc. will be splashed on the ground, causing people to be burned. Thus causing unimaginable accidents and huge losses. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a safety hook and its manufacturing method, which is to inst...
