US Type Clevis Grab Hook Features:

• Clevis Mounting Design for Easy, Secure Installation. A defining feature is its integrated clevis base—a U-shaped metal bracket at the shank end with a pre-drilled hole. This design allows the hook to be quickly mounted to fixed anchor points (e.g., trailer D-rings, truck bed tie-downs, or rigging hardware like shackles) using a pin or bolt. The clevis ensures a rigid, non-rotating connection, preventing the hook from shifting during load tensioning or transit—critical for maintaining alignment in high-stress US transportation scenarios.

• "Grab" Hook Geometry for Instant Chain Engagement. Unlike standard hooks, the US Type Clevis Grab Hook features a specialized throat and jaw design engineered to "grab" and lock onto specific links of transport chains (most commonly G70 or G80 grade—industry standards in US logistics). The throat is narrow and precision-sized to fit the chain’s link diameter snugly, while the jaw has a slight indentation that seats the chain link securely. This allows operators to attach/detach the hook to chains in seconds (no need for threading or complex alignment), accelerating load-securing workflows.

• High-Strength Alloy Steel Construction (US-Grade Durability). Manufactured from heat-treated G70 or higher-grade alloy steel—the benchmark for US heavy-duty rigging. The steel undergoes quenching and tempering to enhance tensile strength, impact resistance, and wear resistance, enabling the hook to handle working load limits (WLL) typically ranging from 5,000 to 15,000+ pounds (varies by size). This construction resists deformation, bending, or cracking even under extreme tension (e.g., securing heavy machinery on flatbeds), meeting the rigorous demands of US industrial and transportation sectors.

US Type Clevis Grab Hook Typical Applications:

• Cargo transportation fixation: In road and rail transportation, it can be used to fix the cargo to the transport vehicle through the chain to prevent the cargo from moving during transportation. For example, it can be installed in the truck compartment or train compartment, connected to the chain through the U-shaped clamp, and hooked to the fixed point on the cargo, which can effectively fix heavy machinery and equipment, construction materials and other cargo.

• Trailer and traction: It can be used to connect the safety chain between the trailer and the towed vehicle or equipment. For example, in a car trailer, one end of the grab hook is connected to the trailer, and the other end is hooked to the chain of the towed car to ensure a firm connection during the traction process and ensure driving safety. It can also be used for the traction of engineering equipment, such as traction of excavators, loaders, etc.

• Industrial lifting assistance: It can be used as a lifting auxiliary tool in factories, construction sites and other places. Although it is generally not directly used for high-altitude lifting of heavy objects, it can be used to fix and connect the chain during the lifting process, help adjust the position and angle of the cargo, and ensure the smooth progress of the lifting operation. For example, when installing large equipment, with other lifting tools, the chain is fixed with a grab hook, and the auxiliary equipment is precisely in place.

• Warehousing and logistics: In warehouses, it is used to fix chains when handling and stacking goods, which facilitates the loading and unloading and stacking of goods. For example, after the goods are tied with chains, the ends of the chains are fixed with grab hooks, which is convenient for forklifts and other handling equipment to operate, improving the efficiency of warehousing and logistics.

• Agricultural field: In agricultural production, it can be used to tow agricultural machinery or fix agricultural products. For example, in farmland transportation, it is installed on a tractor to connect and fix the trailer chain for transporting agricultural products, or to tow agricultural machinery such as plowing and sowing, to adapt to the complex working environment in the field.
