Hanger with steel-reel damage-proof function

Abstract

The invention relates to a cargo sling with damage preventing function for steel coil, wherein the inside of a clamp arm of the cargo sling is provided with a vertical shaft capable of moving along the radial direction of the clamp arm and an elastic component arranged at the inside of the vertical shaft; the vertical shaft is also provided with a spring and a sliding piece pushed by the spring with the external surface protruding above the internal side face of the clamp arm. The sliding piece can gradually increase the acting force generated between the clamp arm and the end face of the steel coil so as to exert the gradually increasing acting force on the scraggly end face of the steel coil; moreover, the sliding piece flattens the scraggly end face of the steel coil through gradually extruding, thereby maintaining flatness of the end face without causing any damage on the end face.

Description

Technical field:

[0001] The invention relates to a hoist with the function of preventing damage to steel coils which can be hung on the hook of a crane or an elevator, the hoist comprises a suspension element and a clamp arm installed in the lower area of ​​the suspension element. Background technique:

[0002] Spreaders for handling steel coils in the prior art generally comprise a suspension element connectable to a hook of a crane or an elevator and a clamp arm installed in the lower area of ​​the suspension element, wherein the suspension element has an internally mounted The rectangular part of the electric component, and the clamp arm is composed of two rods with opposite ends bent respectively, and the upper bent part is installed in the lower area of ​​the suspension element, and the lower bent part forms a hole that can be inserted into the hollow of the steel coil hook. The electric part in the suspension element is used to control the action of the clamp arm, whi...
