Dongfeng KR truck parts Fuel tank bracket assembly 1101105-TR950

Designed to secure fuel tanks weighing up to 300kg (including full fuel load), the bracket uses high-grade structural steel for exceptional load capacity. The main support beams are crafted from 5mm-thick Q345B low-alloy steel (tensile strength 470–630 MPa), capable of withstanding static loads of 600kg (2x the rated weight) without bending. The U-bolt clamps (12mm diameter, 304 stainless steel) feature a reinforced thread design that resists stripping under tension, while the bracket’s crossbars (4mm-thick steel) distribute the tank’s weight evenly across the chassis frame—preventing localized stress on frame rails. Unlike thin mild steel brackets that deform under heavy loads, this heavy-duty design endures 200,000+ km of driving (including rough gravel roads) without structural failure, ensuring the fuel tank remains securely fastened

Built to resist corrosion from road salt, rain, fuel spills, and humidity, the bracket features a comprehensive three-stage anti-corrosion treatment. First, it undergoes hot-dip galvanization (zinc coating thickness ≥85μm) to create a base rust barrier. Next, an electrostatic epoxy primer (60μm thickness) is applied for enhanced coating adhesion, followed by a black polyester topcoat (70μm thickness) that matches the chassis’s underbody color. This coating system passes 1,000 hours of neutral salt spray testing (equivalent to 8 years of road salt exposure) without rust, peeling, or fading. The U-bolts are also stainless steel with a passivated finish, and the mounting nuts include anti-seize compound to prevent thread corrosion—ensuring easy disassembly during maintenance. Unlike single-layer painted brackets that rust within 1–2 years, this design maintains structural integrity in harsh environments

Engineered to absorb road vibration and protect the fuel tank from minor impacts, the bracket integrates vibration-damping components and impact-resistant features. Between the bracket and fuel tank, 8mm-thick EPDM rubber pads (70 Shore A hardness) are installed to dampen chassis vibration—reducing noise from tank movement by 35% and preventing metal-to-metal wear on the tank’s outer surface. The bracket’s edges are folded (15mm flange) and reinforced with gussets (3mm-thick steel) to absorb impact energy from road debris (e.g., stones, curbs), preventing denting or cracking. Additionally, the U-bolts are fitted with rubber washers that create a flexible connection, allowing slight tank movement during rough driving without compromising security. Unlike rigid brackets that transfer vibration to the tank (causing fuel sloshing noise), this design balances stability and flexibility for long-haul comfort

Designed for hassle-free replacement by fleet technicians or DIY owners, the bracket simplifies installation with precision-aligned features and complete hardware. It includes all necessary components: 4 M12×30mm chassis mounting bolts, 2 stainless steel U-bolts, 8 rubber damping pads, and lock washers—no specialized tools required. The bracket has laser-etched alignment marks that line up with reference points on the chassis frame and fuel tank, eliminating guesswork and reducing installation time by 30%. Installation takes 30–40 minutes: position the bracket on the chassis, secure the mounting bolts (torque to 65 N·m), place the rubber pads on the tank contact surface, lower the fuel tank onto the bracket, and tighten the U-bolts (torque to 50 N·m). Each unit undergoes dimensional verification via CMM, load-bearing testing, and corrosion resistance checks, backed by a 24-month warranty against defects (e.g., bending, rusting, U-bolt failure)
