Product Description

Triangle lifting ring description

1. Analysis of Structure and Functional Core

Triangle lifting ring is a high-strength, multi-directional lifting connection. Its design breaks through the limitations of traditional single ring lifting points and achieves safe lifting under complex working conditions through a triangular mechanical framework and modular lifting points. The core structure includes the following elements:

Triangle main frame:

Equilateral/isosceles geometry: By optimizing the aspect ratio (such as 1:1:1 or 1:1.2:1.2) to disperse stress, the risk of single point stress concentration is reduced, and the bearing capacity is increased by 30% -50% compared to a single ring suspension point.

Material strengthening: Q355B high-strength steel (yield strength ≥ 355MPa) or alloy steel (such as 42CrMo) is used, combined with heat treatment (quenched and tempered HRC 28-32) to enhance fatigue resistance.

Multi directional suspension point design:

360 ° Rotating Lifting Ears: Each vertex is equipped with a forged lifting ear (diameter ≥ 20mm) that can rotate freely, adapting to different angles of the sling in different directions to reduce sling twisting during lifting.

Anti decoupling insurance: The lifting ears are equipped with spring locking devices, which can maintain a locking rate of over 95% under lifting impact loads, avoiding the risk of decoupling.

• Scalable interface:

Modular lifting points: The main frame is reserved with M20-M36 threaded holes or ear interfaces, which support quick installation of accessories such as lifting rings and shackles, meeting the needs of multi device serial lifting.

• Weight sensor integration: optional embedded strain gauges (accuracy ± 0.5%), real-time monitoring of lifting loads and feedback to the control system.

2. Core functional advantages

Multi directional force stability:

The triangular frame decomposes the lifting load into three components, and through finite element analysis (FEA) verification, the stress concentration factor of the main frame is reduced by 60% compared to a single ring lifting point at a 45 ° lifting angle.

The rotational freedom of the lifting lug can eliminate the additional bending moment caused by the twisting of the sling and reduce the vibration amplitude of the lifting equipment.
4. Typical application scenarios

Heavy equipment lifting:

Wind turbine blades (single piece weight ≥ 30 tons) are hoisted, and the stress at the lifting point is dispersed through the multi-directional force of the triangular lifting ring to avoid local deformation of the blades.

The pressure vessel of the nuclear power plant reactor (weighing ≥ 500 tons) is lifted using high-strength alloy steel lifting rings (Q960E) to meet the safety standards for lifting nuclear grade equipment.

• Complex structure hoisting:

Bridge steel box girder lifting, achieved through modular lifting point expansion interface to achieve synchronous lifting of multiple lifting points, with precision error controlled within ± 5mm.

Modular lifting of offshore platforms, with a composite coating of hot-dip galvanized and fluorocarbon paint on the surface of the lifting rings (salt spray test ≥ 2000 hours), suitable for highly corrosive marine environments.
