Precast Concrete Lifting Clutches are a type of lifting device used in precast concrete elements, which play a vital role in construction and civil engineering. These lifting clutches are used to safely lift and carry heavy loads such as wall slabs, columns, beams, floor slabs, etc. by connecting them to ball head lifting anchors or other types of lifting anchors prefabricated in the concrete elements.
Uses and Features
⚙ Uses
Precast Concrete Lifting Clutches are primarily used to safely lift, carry and position precast concrete components. They are used on construction sites for lifting wall panels, columns, beams, floor slabs, stairs, access holes, box culverts, pipes, acoustic barriers and more.
⚙ Features
These clutches are designed to be lightweight yet strong to provide a strong grip to ensure that members do not accidentally fall off during lifting. They usually have a unique groove design that fits tightly into the anchor head to provide a secure connection.
