805801472 XCMG GR2605 motor grader hoof clamp d16

805801472 XCMG GR2605 motor grader hoop clamp d16

The XCMG GR2605 grader 805801472 hoof clamp D16 (hoop-shaped clamp D16) is a dedicated fastening component for the machine’s fine-diameter hydraulic branch pipes, coolant fine pipes, fuel return pipes, and wiring harness protection pipes. It is manufactured in strict accordance with XCMG’s original design standards and the JB/T8870-1999 industry standard. It is specially designed for the refined piping system of the Cummins QSB6.7 engine and is suitable for harsh working environments with high vibration, high dust, and alternating high and low temperatures, such as highway construction, airport construction, mining operations, and large-scale earthmoving. As a “precision fixing lock” for small-diameter pipes, it adopts a biomimetic horseshoe-shaped structure design, specifically customized for pipes with an outer diameter of 16mm. With an adjustment range of 12-16mm, it is responsible for precisely fixing small-diameter pipes to the frame or bracket, effectively preventing displacement, wear, leakage, or detachment of the pipes due to severe vibration during equipment operation. This avoids system problems caused by small-diameter pipe failures and is a high-quality original equipment manufacturer (OEM) accessory for the GR2605 motor grader’s refined pipe maintenance and aging replacement.

This horseshoe-shaped clamp is forged from 304 stainless steel in one piece, with a chromium content ≥18%, a nickel content ≥8%, a tensile strength ≥520MPa, and a yield strength ≥205MPa. It possesses excellent corrosion and rust resistance, can withstand immersion in mud and water, acid and alkali environments, and outdoor UV aging, and is not easily deformed or broken with long-term use. Addressing the vulnerability of small-diameter pipes to pressure damage, the clamp’s inner wall features three fine, anti-slip serrations (formed in one piece using a toothed stamping die), increasing the contact area with the pipe surface by 40%. This creates a “biting” clamping effect, raising the coefficient of friction to 0.9, ensuring stability even under 25g peak vibration conditions without slippage. The horseshoe-shaped structure precisely conforms to the curvature of the φ16mm pipe, ensuring even force distribution and preventing excessive local pressure from damaging the outer protective layer or paint.

The clamp is equipped with a high-strength stainless steel single-ended bolt and anti-loosening nut. The bolt undergoes thread rolling reinforcement, achieving a thread precision of 6H, compatible with M6 threads, and a tightening torque of up to 25N·m (meeting the torque standard for 304 stainless steel bolts). Used with an anti-loosening washer, it is not prone to loosening under alternating high and low temperatures (-40℃ to 120℃) and long-term vibration environments, ensuring reliable fixation. The clamp width is designed to be 12mm, and the contact surface of the mounting bracket is precision milled with a flatness error of ≤0.03mm, ensuring a tight fit with the original vehicle’s pipe bracket, distributing pressure, and preventing localized wear caused by vibration. The surface undergoes electrolytic polishing, with a roughness Ra≤0.6μm, making it less prone to dust and mud accumulation, facilitating cleaning and maintenance, and further enhancing corrosion resistance.

The product dimensions and mounting hole spacing are precisely matched to the XCMG GR2605 original vehicle precision pipe bracket, with hole tolerance controlled within ±0.02mm. It is compatible with various small-diameter pipes such as 16mm hydraulic branch pipes, coolant thin pipes, fuel return pipes, and wiring harness protection pipes. No additional drilling or modification is required; installation only requires evenly tightening the bolts with a wrench to complete the fixation. Single-person operation is possible, making assembly and disassembly highly efficient. The compatibility of the clamps with small-diameter pipes and supports has been verified by the original factory. They can work together with the matching small pipes of components such as the 803077507 radiator assembly and the 381100412 engine inlet connecting bend to ensure the precise and stable operation of the entire fluid system.
