Concrete Swift Lifting Pin (Dog Bone) Anchors

Lifting Anchors are also known as a pin or "dog bone". They are divided into T-shaped anchors and eye-shaped anchors according to their shapes. Lifting Anchor is a hot forged insert made of 20Mn2 alloy structural steel. Lifting anchors do not rely on welding or threaded joints to develop safe working loads. Forgings provide reliable safety with their superior material properties and are designed to meet OSHA 4 to 1 safety factor requirements. The mainstream working loads are 1.3T, 2.5T, 5T, 10T. In addition, lifting anchors of different lengths are selected according to the size of precast concrete. The pin anchor indicates the allowable load. Please avoid mismatched joints during lifting operations to ensure operator safety and the integrity of concrete components.

Lifting anchor operation is safe and simple. The lifting pin anchor system adopts a scientific engineering method, combining the lifting anchor, groove former, and customized lifting clutch. The clutch connection can quickly engage the anchor and prepare for the crane hook, helping you to easily handle the lifting of concrete elements.

Key Features

Material and Construction: Lifting Pin Anchors are typically made from high-strength steel, using hot forging techniques. Materials include 20Mn2 steel, with options for stainless steel (SUS304, SUS316) available upon request. The surface treatment can vary, including options like electro-galvanizing, hot-dip galvanizing, and blackening to enhance durability and corrosion resistance.

Design and Functionality: The design resembles a dog bone shape, which allows for effective load distribution during lifting. They are used in conjunction with lifting clutches and recess formers to improve the efficiency of precast concrete wall production. The safety factor for these anchors is 4:1, depending on the specific product specifications.

Applications: Lifting Pin Anchors are versatile and can be used for various precast elements, including underground utility structures, culverts, curb inlets, catch basins, manholes, wall panels, deck slabs, and highway barriers. Their placement is optimized for lifting from both vertical and horizontal surfaces.
