Welcome to this critical safety and ergonomic analysis of the Conjunto de reposabrazos FAW. este es el completo, 4-tipo de componente, trabajo pesado “assist handle” system for the cab of the FAW Jiefang CA4251P66K24T1A3E5 6×4 tractor semirremolque diésel. Esto no es un “comodidad” brazo; it is a primary structural component. Su núcleo “lógica” es proporcionar un seguro, load-bearing hand-hold, enabling a driver to safely maintain “3-point contact” when climbing into or out of the high cab-over-engine.
El Conjunto de reposabrazos FAW is an integral part of the vehicle’s safety and access “lógica,” working in conjunction with the ‘Wing Panel Logic Assembly’ (Asamblea 622) pasos. This system is comprised of two mirror-image ‘Armrest Assemblies’ (Izquierda: 5302115-D03, Bien: 5302120-D03) and a robust 14-piece fastener kit. El “lógica” of its design is to provide an unyielding anchor point capable of supporting the full body weight of a driver, in all weather conditions.
Esta guía detallada es un recurso esencial para los técnicos de talleres de carrocería., collision specialists, and fleet safety managers. Deconstruiremos todo Conjunto de reposabrazos FAW en su 4 unidad mínima útil distinta (Universidad Estatal de Michigan) tipos. Analizaremos el “structural core” logic of the main handles, their ergonomic and material design, y el critico, dual-type “antivibración” fastener system that secures them directly to the cab’s structural A-pillars.
Los componentes primarios del Conjunto de reposabrazos FAW are the ‘Left armrest assy’ (5302115-D03) and ‘Right armrest assy’ (5302120-D03). These are the main structural MSUs. As “izquierda” y “bien” regiones, they are mirror images, but their “lógica” is identical: para proporcionar un seguro, ergonómico “assist handle” for cab ingress and egress.
1. El “3-Punto de contacto” Lógica de seguridad:
Este es el #1 “lógica” de esta asamblea. Slips and falls from heavy equipment are a leading cause of driver injury. Occupational safety regulations mandate a “3-point contact” rule, meaning the driver must always have two hands and one foot, or two feet and one hand, in contact with the vehicle when climbing or descending.
El Conjunto de reposabrazos FAW es el “mano” part of this equation. It is precisely positioned on the cab’s A-pillar to work in concert with the ‘3-stage step panel’ (Asamblea 622). Es “lógica” is to be at the perfect height to allow a driver to pull their entire body weight up, transitioning their grip from the lower handle to the upper handle as they ascend into the cab.
2. El “Ergonómico” Lógica (Diseño):
El diseño de la Conjunto de reposabrazos FAW is not arbitrary. Es “lógica” is based on ergonomics.
A common misconception is that the Conjunto de reposabrazos FAW is just a piece of plastic. This is incorrect. El “lógica” of its construction is a “steel-in-polymer” diseño, similar to a modern steering wheel.
The Steel “Armature”: The true “lógica” of this MSU is a hidden internal structure. Inside the polymer molding is a heavy-duty, acero fabricado “armadura” o “core.” This steel core provides the actual structural strength. This core has the mounting plates with the 7 bolt holes, and it is this steel that is fastened directly to the cab’s structural ‘Welded Cab Assembly’ (Asamblea 617) A-pillar.
The Polymer “Over-Mold”: The plastic that the driver touches is an “over-mold.” Este “lógica” is what provides all the ergonomic and comfort benefits:
Como MSU, these are high-wear items. They are replaced when the outer polymer is cracked (exposing the steel core), or if the unit is bent or broken in a collision.
Este último grupo de MSU es el “lógica” que asegura la Conjunto de reposabrazos FAW stays “rock solid” for the life of the truck. This system is subjected to the constant “tracción” force of drivers *and* the constant, high-frequency “zumbido” of the diesel engine.
El “lógica de sujetadores” is to use 14 total “Pernos combinados,” split into two different grip-lengths.
Universidad Estatal de Michigan 3: «Perno combinado’ (CQ1460816F6) – Cantidad 6
Universidad Estatal de Michigan 4: «Perno combinado’ (CQ1460825F6) – Cantidad 8
El “lógica” de 14 total bolts means each armrest (Izquierda y derecha) is secured by **seven** bolts. This is a massively over-engineered, high-strength connection, proving this is a structural, componente de carga.
El “Combinación” (combinación) logic is the most critical feature. These are not simple bolts. They have a *captive, arandela de seguridad preinstalada* (P.EJ., una arandela dentada o de resorte) under the head. Este “lógica” es 100% about anti-vibration.
The lock washer bites into the steel armature of the handle and the steel A-pillar of the cab, creating constant tension. This makes it physically impossible for the bolt to back out or loosen from vibration. This is what prevents the Conjunto de reposabrazos FAW from developing a “wiggle” o “traqueteo” con el tiempo, which would lead to a catastrophic shear failure. The two different part numbers (CQ1460816F6 and CQ1460825F6) simply refer to different lengths, as the bolts must pass through different thicknesses of the A-pillar’s reinforced structure.
