Welcome to the premium Sinotruk Sitrak parts collection. Our Sitrak Single-Tooth Difference Spare Tire Mounting Device is an essential and robust mechanism designed for the secure storage and easy deployment of spare tires on heavy-duty trucks. This innovative mounting system provides a reliable and convenient solution for drivers and fleet operators, ensuring that a spare tire is always accessible and safely stowed. Engineered for durability and ease of use, this device helps maintain operational readiness and safety for your SINOTRUK Sitrak vehicle in any situation.
The Sitrak Single-Tooth Difference Spare Tire Mounting Device is a specialized mechanical assembly designed to securely hold and lower a spare tire on the side of a heavy-duty truck. It is a side-mounted system that typically includes a sturdy carrier frame, a hand-crank mechanism (winch), and all necessary high-strength mounting hardware. The core of its operation is a single-tooth differential gear system that provides a significant mechanical advantage, allowing a single operator to safely raise or lower a heavy truck tire with minimal effort, even in challenging field conditions.
This assembly consists of several key components. The main structure is the side-mounted spare tire carrier frame, which is welded from robust steel to withstand the weight and vibration of the tire during travel. The crank handle assembly engages with the gear mechanism, allowing the user to wind a cable or chain that lifts the tire into its stored position under the truck’s chassis or on its side. The device is designed to lock securely in place, preventing any accidental release or movement of the spare tire while the vehicle is in motion.
The kit includes all required high-grade fasteners for installation, such as hex head bolts, flange nuts, and specific wheel nuts for securing the tire to the carrier itself. The hardware is selected for its tensile strength and corrosion resistance, ensuring the entire mounting system remains secure and functional over the long term, even when exposed to harsh weather and road conditions. Proper installation is crucial for safety and reliability, which is why genuine SINOTRUK parts and specifications are always recommended.
This device is an integral part of a truck’s safety equipment, ensuring that a spare tire is always available and can be accessed without the need for heavy lifting equipment. It saves valuable time during roadside tire changes and reduces the risk of injury associated with manual handling of heavy wheels. Manufactured to exacting standards for SINOTRUK Sitrak trucks, this mounting device offers a perfect fit, reliable performance, and peace of mind for drivers and fleet managers alike.
