At the core of SIMEN PRECAST’s Ring Lifting Clutch is a thoughtfully designed two-part structure: a precision-forged ring shackle and a heavy-duty clutch head, working in perfect harmony to redefine precast lifting flexibility. The ring shackle features a closed-loop design that allows 360° free rotation and multi-angle adjustment, enabling seamless alignment with lifting slings or hooks regardless of the precast element’s orientation. This rotational flexibility eliminates lateral stress on both the clutch and the precast panel, minimizing the risk of cracking, spalling, or structural damage during lifting, turning, or tilting operations—especially critical for irregularly shaped elements like facade panels and beam components.

Durability and load-bearing reliability are non-negotiable for SIMEN PRECAST, and the Ring Lifting Clutch delivers on both fronts through premium materials and strict manufacturing standards. Crafted from high-strength alloy steel grades—including Q345D, 35CrMoV, and customizable options—the clutch undergoes precision hot forging and heat treatment to enhance material density, tensile strength, and impact resistance. Each unit is available in a wide range of safe working loads (SWL) from 2.5 tons to 26 tons, covering diverse precast needs from lightweight wall panels to heavy structural slabs, while its compact design ensures easy integration with standard spread anchor systems.

Safety is embedded in every detail of the Ring Lifting Clutch’s design, starting with its secure engagement mechanism. The clutch head is equipped with an integrated locking bolt that firmly fastens to matching lifting anchors, guaranteeing non-spontaneous disengagement under load at any orientation—provided it is paired with the correct anchor type. To further enhance on-site safety, each clutch features clear, wear-resistant markings indicating load capacity and anchor compatibility, allowing workers to quickly verify proper usage and avoid mismatches that could lead to accidents. With a safety factor of ≥5—exceeding industry averages—the clutch provides an extra layer of protection for on-site teams and valuable precast assets.

Beyond performance, the Ring Lifting Clutch is engineered for ease of use and long-term cost savings. Its streamlined design enables quick engagement and disengagement: once the lift is complete and the load is released, the clutch can be detached in seconds, reducing downtime and boosting on-site productivity. For durability in harsh construction environments, SIMEN PRECAST offers multiple surface treatment options—electro-galvanization (E.Z) and hot-dip galvanization (H.D.G)—forming a corrosion-resistant barrier that extends the clutch’s service life by 5-8 years and reduces maintenance costs over the project lifecycle. Additionally, the clutch’s optimized manufacturing process minimizes material waste, delivering cost-effective solutions for bulk orders without compromising quality.
