Sany Bracket Assy-Spare Wheel — OEM spare tire mounting bracket for Sany heavy trucks and mining equipment

What is the Sany Bracket Assy-Spare Wheel?

The Sany Bracket Assy-Spare Wheel is a purpose-built mounting frame that secures the spare tire to the chassis of Sany heavy trucks and construction vehicles. This OEM assembly is engineered to withstand the extreme forces encountered during off-road operation, including vibration, shock loads, and torsional stresses that can cause generic brackets to fail. The assembly is typically mounted beneath the rear frame or at the rear bulkhead of the vehicle, depending on the chassis configuration of specific Sany models such as the SKT series mining dump trucks, STC series cranes, and SY series excavators.

The Sany Bracket Assy-Spare Wheel consists of six precision-engineered components: the primary spare tyre rack (00000191) fabricated from high-strength steel, two hardened pins (A210491000017 and A210491000018) that provide the main articulation points, the lower lock pin (00000339) and upper lock pin (00000182) that form the positive latching mechanism, and a high-tensile nut (A210355000007) that secures the assembly against vibration loosening. This integrated system ensures the spare wheel remains firmly attached while remaining accessible for removal when needed.

The spare tyre rack (00000191) is designed with a welded tubular steel construction featuring cross-bracing for maximum rigidity while minimizing weight. The rack is coated with a multi-layer anti-corrosion system, including e-coat and polyester powder finish, providing up to 480 hours of salt spray resistance. This makes the Sany Bracket Assy-Spare Wheel particularly suitable for mining, coastal construction, and winter road applications where exposure to corrosive elements is a daily reality.

The lock pins (upper 00000182 and lower 00000339) are case-hardened to resist wear and maintain precise alignment even after thousands of removal-and-installation cycles. When engaged, these pins create a redundant locking system that prevents accidental release of the spare wheel, even under extreme vibration conditions. The nut (A210355000007) incorporates a nylon-insert prevailing torque feature that maintains clamp force without loosening, eliminating the need for frequent re-tightening. Whether you operate a fleet of Sany dump trucks in a mine site or maintain a single Sany excavator on a construction project, the Sany Bracket Assy-Spare Wheel ensures your backup tire stays securely mounted until it is needed.

Why Choose Our Sany Bracket Assy-Spare Wheel?

OEM Quality and Perfect Fitment: Every Sany Bracket Assy-Spare Wheel is sourced directly from Sany’s authorized production lines, ensuring that all mounting hole locations and frame geometries match the original chassis specifications exactly. Aftermarket brackets often require drilling, welding, or adapter plates—each modification introduces potential failure points. The genuine Sany Bracket Assy-Spare Wheel installs in minutes using the original mounting points, preserving your vehicle’s structural integrity.

Superior Corrosion Protection for Harsh Environments: The Sany Bracket Assy-Spare Wheel features a multi-layer coating system that includes zinc-phosphating base, e-coat primer, and a top layer of durable polyester powder coating. Independent salt spray testing confirms 600+ hours of protection against red rust—critical for fleets operating in coastal regions, winter road salt environments, or mining applications with corrosive chemical exposure. The hardened pins are zinc-flake coated with a top lubricant layer that prevents galling during insertion and removal cycles.

Positive Locking System with Audible Confirmation: The upper lock pin (00000182) and lower lock pin (00000339) feature a spring-loaded detent mechanism that provides audible and tactile feedback when fully engaged. This design eliminates the guesswork during spare wheel installation—operators hear a distinct “click” when the lock pins are properly seated. The redundant two-pin locking system ensures that even if one lock pin were to vibrate loose (extremely unlikely), the second pin would maintain secure retention until the condition is noticed during routine inspection.

Fleet-Proven Durability and Comprehensive Warranty: Field data from Sany fleets operating in Australian mines, Canadian oil sands, and Middle Eastern construction sites confirms that the Sany Bracket Assy-Spare Wheel delivers an average service life exceeding 8 years with proper maintenance. The high-tensile nut (A210355000007) features a nylon-insert locking element that remains effective across a temperature range of -40°C to 120°C. The assembly is backed by a 24-month manufacturer’s warranty covering material defects and premature wear. Fleet managers who standardize on the genuine Sany Bracket Assy-Spare Wheel report a 70% reduction in spare wheel bracket failures compared to generic alternatives.

What are the Routine Maintenance Considerations for the Sany Bracket Assy-Spare Wheel?

Inspect the spare tyre rack and welding points every 500 operating hours: Examine the tubular frame of the spare tyre rack (00000191) for any signs of cracking, bending, or deformation. Pay particular attention to the welded joints where the cross-bracing attaches to the main frame, as these are the most stress-concentrated areas during off-road operation. Use a flashlight to inspect hidden surfaces for rust accumulation. Any visible crack or deformation requires immediate replacement of the rack—field welding is not recommended as it may compromise the heat treatment of the base metal.

Lubricate pins and lock pin mechanisms every 250 hours or quarterly: Apply a lithium-based EP2 grease to the pins (A210491000017 and A210491000018) before inserting them into their respective bushings. Work the lock pins (00000182 and 00000339) in and out several times while applying grease to the spring-loaded detent mechanism. This prevents galling, ensures smooth operation, and protects against corrosion-induced seizure. For fleets operating in extremely dusty environments (coal mines, cement plants, or desert regions), increase lubrication frequency to every 100 hours.

Verify lock pin engagement and check nut torque at every service interval: During each scheduled maintenance, confirm that both the upper lock pin (00000182) and lower lock pin (00000339) are fully inserted with the spring-loaded detent ball protruding through the locking hole. The lock pins should not have any axial movement when seated. Using a torque wrench, verify that the nut (A210355000007) is tightened to the manufacturer specification of 55-65 Nm. Vibration from haul roads or uneven terrain can cause gradual loosening; a quarterly torque check prevents the rack from developing play that would accelerate wear on the pins and bushings.

Replace worn components proactively every 24 months or 4,000 operating hours: For high-use fleets, Sany recommends replacing the lock pin springs and nylon insert in the nut (A210355000007) preventatively every two years, regardless of visual condition. The lock pin springs (upper 00000182 and lower 00000339) lose tension over time, which can lead to incomplete engagement and eventual release of the spare wheel under extreme vibration. The pins (A210491000017 and A210491000018) should be replaced if measurable wear exceeds 0.3 mm in diameter. Keep a maintenance log of replacement dates and torque values to track component lifecycle and ensure compliance with fleet safety protocols.

The Sany Bracket Assy-Spare Wheel features a modular design that allows individual component replacement without discarding the entire assembly. The spare tyre rack (00000191) can be refurbished by replacing the nylon bushings (available separately) through a simple pressing operation. The high-tensile nut (A210355000007) is designed to be reused up to five times before the nylon insert loses its prevailing torque properties, although Sany recommends replacement after every second removal cycle for maximum safety margin in critical mining applications.

For operators in extreme cold climates (below -30°C), Sany recommends pre-heating the lock pin mechanisms (00000182 and 00000339) before attempting release. The spring steel used in the detent mechanism remains functional at low temperatures, but the lubricant can become viscous, impeding smooth operation. Apply a low-temperature synthetic grease rated for arctic conditions during winter maintenance intervals. Never use penetrating oils or solvents on the lock pins, as these can wash away the permanent lubricant and accelerate wear.

The Sany Bracket Assy-Spare Wheel is designed to accommodate up to a 250 kg wheel and tire combination—sufficient for all Sany heavy truck applications. When mounting a replacement spare tire, always use a lifting device or team lift to avoid dropping the tire onto the rack, which can bend the frame and misalign the lock pin receivers. The spare tyre rack (00000191) includes alignment guides that center the wheel during installation, preventing the rim from contacting the chassis frame and causing damage during vibration.

For Sany SKT series mining dump trucks, the Sany Bracket Assy-Spare Wheel is typically mounted beneath the rear chassis between the axles. This underbody location protects the spare tire from overhead falling debris while keeping it accessible from ground level. The assembly is supplied with all necessary mounting hardware, including the pins (A210491000017 and A210491000018), lock pins (00000182 and 00000339), and nut (A210355000007). No additional washers, bolts, or brackets are required for standard chassis installations.
