Description

Spreader suitable for single hook hoisting

technical field

The utility model relates to a load hanging device, in particular to a sling type sling.

Background technique

Missiles are an important component of weapon systems. Hoisting and reloading is one of the important links in the whole process of missiles. The connection between hoisting equipment and missiles is firm and reliable, and the safe implementation of hoisting functions is of great significance to the safety of missiles. At present, there are two forms of hoisting for missiles, single hook and double hook. Single-hook hoisting requires a centroid adjustment function for horizontal hoisting of missiles, while double-hook hoisting is relatively simple. The main interface form of hoisting is generally the lifting trunnion or the lifting lug hole. This kind of hoisting method requires the local structure of the missile to have a reinforced ring frame, which is strong enough to withstand its own load, hoisting impact and the influence of external environmental conditions during hoisting. In order to reduce the weight and the structure of the missile is relatively weak, it is necessary to develop a hoisting device that adapts to its structural characteristics and meets the safety requirements.
