130904000044B005 Right box frame Sany SY1350C1C3KH Tracked hydraulic excavator spare parts

The 130904000044B005 right-side box frame is a custom-made core load-bearing support component for the right-side box, compatible with various engineering machinery cabs. It is primarily used for the overall support, structural fixation, and protection of internal components of the right-side box. It also features stable load-bearing capacity, impact and vibration resistance, deformation prevention, and positioning and limiting functions. Suitable for bumpy operations in mines and construction sites, the frame structure evenly transmits vertical pressure, preventing deformation, collapse, and loosening of the right-side box. It provides solid support for items and electrical components inside the box, ensuring the structural integrity of the right-side box, improving the operational stability of cab components, and complying with relevant engineering machinery protective structure specifications.
This product is an original factory compatible part, precisely matching the right side box of the cab of Sany, XCMG, Caterpillar and other series of construction machinery. It adopts CNC laser cutting, sheet metal bending and precision welding forming process, and is compatible with the original right side box installation position and interior layout. It can be installed quickly without complicated adjustment, and can withstand bumpy, high and low temperature and dusty and oily working conditions. The structure is stable and there is no twisting or deformation.

【Core Technical Parameters】

-Product Model: 130904000044B005
– Product Type: Right Box Frame (Original Equipment Manufacturer, Dedicated Load-Bearing Support Frame for Construction Machinery Cab)
– Compatible with: cabs of Sany, XCMG, Caterpillar, and other series of construction machinery; suitable for right-side support mounting on cabs of loaders, excavators, bulldozers, etc., without affecting the operation and maintenance of surrounding components.
– Material: High-strength cold-rolled steel sheet (Q235B or LG960QT engineering machinery special steel optional), processed by CNC laser cutting, sheet metal bending, precision welding, cathodic electrophoresis + zinc-rich primer. LG960QT material has a yield strength ≥960MPa, overall tensile strength ≥520MPa, hardness HRC28-32, flatness ≤0.3mm, steel sheet thickness optional from 1.2-2.5mm, paint film thickness up to 25μm, and zinc layer content ≥60g/m².
– Operating temperature range: -40°C to +80°C (The structure remains stable under extreme temperatures, with no reduction in load-bearing capacity, no brittleness, no aging, and no deformation. The LG960QT material still has good impact toughness at -60°C).
– Structural Specifications: Integrated frame structure, including the main skeleton, 50×50mm reinforcing angle steel, longitudinal and transverse reinforcing ribs, positioning clips and mounting holes. The welds at the joints are full, employing a double-row staggered welding process to evenly transmit vertical pressure. It combines load-bearing support, positioning and fixing, and protective reinforcement functions, conforming precisely to the internal layout of the right-side enclosure. Inspection holes can be pre-installed as needed.
— Dimensions: Precisely fits the original right-side enclosure; length, width, height, and mounting hole spacing match the enclosure dimensions perfectly. It seamlessly integrates with the inner wall of the right-side enclosure and the installation location. Dimensional tolerances are IT7-IT8 grade, diagonal deviation ≤1mm, and bending accuracy ±0.25mm.
-Installation method: Bolt fixing + welding assistance, compatible with original factory mounting holes. Before installation, clean the mounting surface of burrs and dirt. Convenient and quick replacement. After installation, it is stable without shaking or twisting, with tight splicing and even stress distribution.
– Protective Performance: Waterproof, dustproof, and oil-resistant; surface cathodic electrophoresis + zinc-rich primer treatment; salt spray resistance ≥500 hours; wear-resistant, aging-resistant, and UV-resistant; not easily rusted or deformed; welds are well-sealed; effectively withstands dusty and oily working conditions; LG960QT material enhances overall structural durability.
-Service life: ≥4.5 years under normal working conditions, ≥2.5 years under harsh working conditions; no deformation or cracking after load-bearing fatigue testing; static load capacity ≥600N; can withstand 15 impacts of a 147m/s² half-sine wave without significant deformation; structural deformation rate is lower than the industry average.

Whether in bumpy environments, dusty mines, or extreme temperature conditions, this product consistently delivers stable load-bearing support and protection, ensuring the integrity, stability, and freedom of deformation of the right-side enclosure structure. It provides robust protection for internal items and components, reducing maintenance costs. Original factory compatible and traceable with a unique code, this is a high-quality original part for right-side enclosure frame repair and replacement, and for bulk stocking.
