Abstract

The invention discloses a sling, which is mainly composed of a connecting piece, a left rocker arm, a right rocking arm, a support arm, a lifting arm and a lifting shaft. The upper end of the connecting piece is processed with a hook hole, and the lower end is installed with a first A hinge, the first hinge is connected with one end of the left rocker arm and one end of the right rocker arm, the connecting piece, the left rocker arm and the right rocker arm form a rotatable connection that can rotate around the center of the first hinge, so The other end of the left rocker arm is rotatably connected to the support arm through a second hinge fixed on the support arm, and the other end of the right rocker arm is rotatably connected to the boom through a third hinge fixed on the boom arm. Rotary connection, a lifting tool of the present invention, can realize fast lifting of square heavy objects, easy to operate, safe and reliable lifting, high working efficiency, low manufacturing cost and convenient installation.

Description

technical field [0001] The invention belongs to the technical field of machinery, in particular to a sling used for hoisting square heavy objects. Background technique [0002] Generally, when lifting a square heavy object with a larger length and width, steel wire ropes are often used to bind the square heavy object before lifting. This method is not only time-consuming and laborious, but also very unsafe.
