Specifications

The 45 Ton Pintle Hook by Buyers Products represents a pinnacle of engineering and material science applied to heavy-duty towing applications. This designation, referring to its remarkable Maximum Gross Trailer Weight (M.G.T.W.) capacity of 90,000 pounds (45 tons), positions it as an indispensable component for industries that demand unwavering strength and reliability in their hauling operations. Designed for the most arduous tasks, this bolt-on pintle hook is meticulously crafted to ensure optimal performance, longevity, and safety across a diverse range of operational environments, from demanding construction sites and expansive mining operations to critical agricultural tasks and complex municipal logistics.

Central to the superior performance of this pintle hook is its construction from austempered ductile iron (ADI). ADI is not merely a material; it is a metallurgical triumph resulting from a specialized heat treatment process applied to ductile iron. This process involves heating the ductile iron to an austenitizing temperature, followed by rapid quenching in a salt or polymer bath, and subsequent holding at an intermediate austempering temperature. This precise thermal cycle transforms the material's microstructure into a unique combination of needle-like bainite and high-carbon austenite, eliminating the need for further tempering. The resulting ADI material exhibits an exceptional confluence of properties: remarkably high tensile strength and yield strength, superior ductility, excellent fatigue resistance, and outstanding wear resistance. For a pintle hook, which experiences immense static and dynamic stresses, these properties are critical. The high tensile strength ensures the hook can withstand the enormous pulling forces exerted by a 90,000 lb trailer, while its impressive yield strength guarantees that it will deform minimally under extreme loads, maintaining its structural integrity and operational geometry. Furthermore, the inherent ductility of ADI provides a significant safety margin, allowing the material to flex and absorb shock loads rather than fracturing catastrophically under sudden impacts or severe jolts, which are common in heavy hauling, especially over uneven terrains. Its enhanced fatigue resistance contributes to a longer service life, resisting crack initiation and propagation even after countless load cycles, thereby reducing maintenance frequency and enhancing operational uptime. The exceptional wear resistance, often superior to hardened steels, ensures that critical contact surfaces, particularly the hook and latch mechanism, endure minimal material loss over years of heavy use, preserving the precise fit and secure coupling with the drawbar eye.

Beyond its foundational material, the 45 Ton Pintle Hook features a robust black powder-coated finish. This finishing process is far more than a cosmetic application; it forms a resilient protective layer that significantly contributes to the product's durability and longevity in challenging outdoor and industrial settings. Powder coating involves electrostatically applying a dry powder—comprising polymer resins, pigments, curing agents, and other additives—to the meticulously cleaned and pre-treated surface of the austempered ductile iron. The pintle hook is then subjected to heat in a curing oven, where the powder melts, flows, and chemically cross-links, forming a uniform, hard, and robust coating. This thermoset polymer layer offers unparalleled resistance to chipping, scratching, fading, and abrasion, properties that are essential for equipment regularly exposed to impacts, road debris, and general wear and tear inherent in towing operations. Crucially, the powder coating provides a formidable barrier against environmental degradation. It offers superior corrosion protection by preventing moisture, road salt, chemicals, and other corrosive agents from reaching the underlying metal, thereby safeguarding the ADI from rust and extending its operational lifespan. Unlike conventional liquid paints, powder coatings emit zero or near-zero volatile organic compounds (VOCs) during application, making it a more environmentally responsible choice for manufacturers. The aesthetic benefit of the black powder-coat also endures, maintaining a professional and well-maintained appearance even after extensive use, a testament to its resistance against UV radiation and harsh weather conditions.

The quantitative capabilities of this pintle hook are meticulously specified to ensure both safety and performance. With a Maximum Gross Trailer Weight (M.G.T.W.) of 90,000 lbs, the hook is engineered to manage the aggregate weight of the heaviest trailers and their cargo. This capacity is critical for applications involving multi-axle heavy equipment transporters, large pup trailers, and specialized industrial trailers, where the sheer mass of the towed unit necessitates a robust and secure connection point. Complementing the M.G.T.W. is a Maximum Vertical Load (M.V.L.) capacity of 18,000 lbs. The M.V.L., often referred to as tongue weight or hitch weight, represents the maximum downward force that the trailer's coupling applies to the pintle hook. Proper management of vertical load is crucial for maintaining vehicle stability, braking effectiveness, and steering control. An M.V.L. of 18,000 lbs indicates a design that can accommodate significant downward pressure, characteristic of heavy-duty trailers designed for optimal load distribution. This combination of high M.G.T.W. and M.V.L. validates the "45 Ton" designation in the product title, clearly articulating its intended use for the most demanding hauling scenarios. The hook's design is specifically suited for applications such as heavy equipment hauling in construction and mining sectors, where excavators, bulldozers, and other large machinery need to be transported efficiently and safely. Similarly, in the waste management and agricultural industries, this pintle hook is ideal for towing multi-container pup trailers or large farm implements that exceed the capacities of standard towing apparatuses. Its robust nature also makes it suitable for military and governmental applications where reliability under extreme conditions is paramount.

The installation of the 45 Ton Pintle Hook is designed for secure, permanent attachment via its bolt-on configuration. This method ensures a rigid and direct connection to the towing vehicle's frame or a robust mounting plate, distributing towing forces efficiently and minimizing stress concentrations. The design incorporates precise mounting hole dimensions to facilitate a straightforward and secure fit. Specifically, the horizontal hole spacing is provided at 5.25 inches and 6.50 inches, offering flexibility in integration with various chassis configurations or mounting plates. The vertical hole spacing is set at 3.000 inches, ensuring a standard and repeatable mounting pattern. Each mounting hole has a diameter of 0.781 inches, engineered to accommodate high-strength fasteners (typically Grade 8 bolts, though the mounting kit is sold separately and professional guidance on fastener selection is recommended) that can withstand the intense shear and tensile forces inherent in heavy-duty towing. To ensure optimal performance and safety, each pintle hook package includes comprehensive mounting information, a detailed specs sheet, and a drilling template. These resources are invaluable for installers, providing precise measurements and guidance to achieve accurate alignment and a structurally sound installation. Furthermore, a vehicle capacity decal is supplied, which is essential for clearly marking the towing vehicle's maximum permissible capacities, promoting adherence to safety regulations, and preventing accidental overloading. It is imperative that the mounting kit, which includes the necessary bolts, nuts, and washers, be selected based on the specific application and adhered to the manufacturer's recommendations to guarantee the integrity of the connection.

Compatibility with various trailer types is a critical aspect of any pintle hook, and the 45 Ton Pintle Hook is designed to accommodate a common range of drawbar eyes.
