Description

Hoist lifting hook frame

Technical Field

The utility model relates to a calabash fitting piece technical field, concretely relates to calabash hook frame.

Background

The hoist is a hoisting tool, which is driven by a circular chain, and has two types of manual and electric operation, and the hoisting capacity of a single chain is limited, so the hoist with a larger tonnage is usually realized by a multi-row chain mode, for example, a lower hook frame of a 3-row chain is composed of a loose pulley and a hanging chain plate. Because the hanging chain plate needs to be installed, the width of the lower hook frame is increased, the span of the loose pulley shaft is increased, and the diameter of the loose pulley shaft needs to be increased or the material performance needs to be improved or the heat treatment requirement needs to be improved on the premise that the strength is ensured again due to the increase of the span of the loose pulley shaft. The addition of a number of factors contributes to the difficulty and cost of manufacturing such lower hook brackets.
