Lifting Anchor Introduction

The lifting Anchor is hot forged from Manganese steel. The former head provides spherical seating that the Lifting Eye engages, while a disc-shaped foot is embedded in the concrete. Due to its being a forged part, the lift anchor does not depend on welds or thread engagement to develop its safe working load. Forging provides maximum safety with its advantageous material structure. This allows the anchor to easily meet the OSHA requirement of a 4 to 1 factor of safety. We currently have to lift anchors in various styles and weights, and the factory-direct sales price is competitive. Lifting Anchor is the most versatile and widely used anchor in the Lifting Anchor range. Available in a wide range of Working Load Limits (WLL), all Lifting anchors comply with AS 3850.1:2015. Lifting Anchor has been extensively tested in concrete, comprising over 500 individual tests and consuming approximately 150 tons of concrete.

Spherical Head T Anchor Testing Report

Before each batch of lifting anchors is shipped for export, we conduct a rigorous quality inspection process and send the corresponding inspection report to the customer for confirmation in advance. The inspection typically includes visual and dimensional checks, verification of the consistency of key component processing, and confirmation of surface treatment quality. Sampling tests are also conducted when necessary to ensure consistent product quality in terms of assembly compatibility and safety.
Furthermore, our production and quality control records support batch traceability (batch number/production records/inspection records are available), ensuring that the products meet export requirements and factory production standards. If customers have specific project or acceptance criteria, we also support adding designated testing items and provide corresponding documents or photos/videos to help customers complete acceptance and delivery more efficiently.

Application of the lifting anchor

Lifting anchors play a crucial role in the safe handling, transportation, and installation of precast concrete components. As an essential part of certified lifting systems, they provide reliable and controllable connection points at every stage of the lifting process. From the production line to on-site installation, lifting anchors simplify handling operations, reduce labor risks, and accelerate installation schedules. In precast slabs and floor units, anchors enable efficient demolding, stacking, and installation, thereby increasing productivity in both the factory and on the construction site.

Quality Management System

Our factory performs process management based on customer orientation emphasizes process control, quality cost management, and reducing waste. We also use the Advantaged Product Quality Planning (PAPP), Potential Failure Mode and Effects Analysis (FMEA), Statistical Process Control (SPEC), Production Part Approval Process (PPAP), Measurement System Analysis (MAS), and Error Proofing method to prevent defects from happening.

Our purchasing manager has more than 7 years of purchasing experience and is rich in experience in quality control and the advantages of different factories, different products, and different quality levels.

Criteria for Anchor Selection

The maximum load capacity, edge distance, and mounting values can be found in the corresponding tables. No matter which type of anchor is selected (based on the load acting on the anchor), the following factors must be considered:

● weight of performers

● number of anchors

● anchor layout

● number of load-bearing anchors

● the opening angle in the hoist

● Anchor diagonal pull characteristics

● dynamic load

●adhesion to formwork if the slab is cast horizontally and then lifted upright without a tilt table, ensure adequate reinforcement

Number of Anchors

The number of anchors determines the type of hoist to be used. A hoist with more than two cables is statically uncertain if the anchors are aligned along a single axis. A hoist with more than three cables is considered to be statically uncertain if no measures are taken to ensure that the load is distributed between all anchors (e.g., using extension beams, etc.).

Load Capacity

The load capacity of the anchor depends on:

● concrete compression strength foci at time of lift (cube-test 15 × 15 × 15 cm)

● anchorage length of the anchor

● edge and axial anchor-spacing

● load direction

● reinforcement layout

Installation and Application

Anchor installation and application – Static system

Transport anchors are made out of killed steel with a high notch toughness, which retains its safe load capacity under shock load in temperatures as low as 20 °C. Transport anchors production is DIN EN ISO 9001 certified and is subjected to continuous monitoring. The spherical head transport anchor is cast in with the recess former attached. After the concrete has se,t the recess former is removed; the lifting link can then be attached to the transport anchor. The connection fulfills all work regulation safety requirements; the transport anchor is in a recess, and there are no protruding parts in the finished elements.

A wide selection of transport anchors in various load classes and lengths guarantees that for nearly every shape of a reinforced concrete precast element, the required technical, correct solution is available and remains cost-efficient– for conventional building projects(beams, ceiling slabs, trusses, columns

and stairs); and also, for utility and excavation projects (pipes and shafts).

Load transfer and failure behavior

The spherical head anchors for load class 1.3 to 45.0 are forged from rod material. Depending on the application, anchors are available in different lengths. Longer anchors are available if reduced edge spacing or low concrete strengths need to be considered.

The load transfer into the concrete is via the anchor foot. This allows high possible loads with relatively short anchor lengths. In very thin elements, these concentrated loads lead to lateral spalling caused by high tensile splitting.

Compared with other transport anchor systems, the symmetrical design of the anchor foot does not require specific placement when installing the anchor (rotational symmetry).

In typical wall thicknesses, the concentrated load distribution as displayed by the spherical head transport anchor foot has advantages in comparison with a gradual, supposedly smooth load distribution affecting ribbed steel. This has been proved in numerous tests by the Institute for Concrete and Masonry Construction at the Technical University of Darmstadt (Institute for Solid Construction der TU Darmstadt). A typical failure pattern in tests is a cone-shaped failure originating from the foot of the anchor. By using a longer anchor, a larger area is utilized to distribute the load in the concrete.

1. Expected failure if the anchor load is too high Lifting Anchor application

2. Blow-out failure only in very thin elements

The length of the spherical head transport anchors depends on the concrete cross-section and concrete grade, and they are designed for optimal load capacity.

The universal head lifting link rests against the concrete in a diagonal pull and transfers the horizontal load factor directly into the concrete.

Consequently, there is no reduction in load-bearing capacity to account for diagonal loading in large surface elements. For example, as is standard for sleeve anchors. Additional reinforcement is not required. Lifting Anchor application

Additional diagonal bursting reinforcement is required in thin-wall elements

. Details can be found in the section "Spherical head transport anchor for beams and walls.

A tilting aid is required with transverse stress in thin-wall elements at 90 degrees to the slab surface. A tilting anchor can be used for load classes 2,5 and 5,0. We generally recommend using a tilting table.

Multi-layer elements can be moved using the offset spherical head rod anchor or the offset spherical head transport anchor.
