Product Introduction

The three-legged chain rigging is composed of three high-strength alloy steel chains, connecting rings and hooks (or special grippers), and is manufactured by welding or assembly processes. It supports custom chain length, tonnage and end accessories (such as rotating hooks, regulators, etc.). Its core design achieves balanced load distribution through the symmetrical distribution of three limbs, making it suitable for vertical lifting and binding operations of circular, annular or objects with a shifted center of gravity. The rated load range covers from 1 ton to 70 tons.

Product advantages and features

Three-dimensional balanced hoisting ‌

It adopts a Y-shaped forked main chain link design, with three branches evenly distributed at 120°. Combined with a dynamic pressure sensor (optional), it can display the force data of each leg in real time, ensuring the stable lifting of irregular objects (such as large castings, wind turbine nacelle).

Compound working condition adaptation ‌

The asymmetric length combination is achieved through the quick-release extension chain (adjustable within ±1m), meeting the eccentric hoisting requirements of special scenarios such as oil pipelines and prefabricated bridge components, and conforming to the ASME B30.26-2018 safety standard for multi-leg rigging.

Anti-sway design ‌

The three-legged rigging reduces the sway of goods in the air by up to 60%, making it particularly suitable for the installation of precision equipment such as pressure vessels in nuclear power plants.

When using chain slings, it is advisable to use a β Angle of no more than 45°. If not specified, it is assumed to be this Angle by default. The β Angle is the Angle between the chain limb and the vertical line.
The above load conversion coefficients and the corresponding rated loads are used when the loads are symmetrically distributed. When they are asymmetrical, the load conversion coefficients should be modified as follows:
Asymmetric load conversion coefficient	-	1	0.8	1.5	1	1.5	1
The lifting rings and lifting ring combinations are selected from factory standard products, with a tonnage equal to or slightly greater than the overall load of the rigging.
