FAW J6P Three-Tier Footrest: Deconstructing 15 Critical Parts for Cab Access Safety

This is a comprehensive guide to the FAW J6P Three-Tier Footrest assembly for the FAW Jiefang CA3250P66K2L1T1E 6×4 dump truck. This deconstruction analyzes the 15 serviceable component types that form this assembly, detailing the main panels, structural brackets, and safety steps that facilitate cab access.

The FAW J6P Three-Tier Footrest system is a critical safety feature designed to provide secure, ergonomic, multi-level access to the high-mounted cab. This system must be structurally robust to handle the full weight and impact forces of the driver and passenger entering and exiting the vehicle multiple times daily. The multi-tier design, integrated into the front wing structure, is essential for minimizing slips, falls, and resulting injuries.

This deconstruction analyzes the key components of the FAW J6P Three-Tier Footrest, focusing on the main panels, the internal steel reinforcement brackets, and the specialized hardware used for maximum safety and rigidity. Maintaining the integrity of the FAW J6P Three-Tier Footrest is non-negotiable for operator safety. Every component listed for the FAW J6P Three-Tier Footrest is critical for ensuring the assembly remains secure and reliable.

Core 1: The “Stepping Surface” Logic (The Plates)

This group represents the actual contact surfaces of the FAW J6P Three-Tier Footrest. Their design ensures maximum grip and durability under heavy use.

1. Component: ‘Left third-level footrest’ (5103191BA01) & ‘Right third-level footrest’ (5103192BA01) – Qty 1 each
This (Comp 3, 4) is the highest step in the **FAW J6P Three-Tier Footrest** sequence. The Ergonomic Access Logic requires this top step to be wide and strong, providing a secure final platform before the driver steps onto the cab floor. These plates feature a high-grip surface finish.

2. Component: ‘Left upper wing panel’ (5103121AB35) & ‘Right upper wing panel’ (5103122AB35) – Qty 1 each
This (Comp 1, 2) is the integrated side panel (wing). These are the parts that the footrest plates (Comp 3, 4) are secured to. The structural integrity of these panels must withstand the dynamic load of a driver using the steps. The **FAW J6P Three-Tier Footrest** relies on this structural pairing.

3. Component: ‘Left upper mudguard’ (5103161-B35) & ‘Right upper mudguard’ (5103162-B35) – Qty 1 each
This (Comp 8, 9) forms the lower structural part of the FAW J6P Three-Tier Footrest assembly, providing the base support for the step mechanism and containing debris from the front wheels.

Core 2: The “Structural Support” Logic (Brackets and Rods)

This group includes the heavy-duty steel framework that reinforces the steps and secures the entire FAW J6P Three-Tier Footrest assembly to the cab structure.

1. Component: ‘Left rear mudguard support bracket assy’ (5103145-B35) & ‘Right rear support bracket assy’ (5103150-B35) – Qty 1 each
This (Comp 10, 11) is the main structural reinforcement for the rear section of the FAW J6P Three-Tier Footrest. These heavy-duty steel brackets are bolted to the cab to absorb the dynamic loads of the steps. The Load Transfer Logic is that these brackets must transfer the force of the driver’s weight directly to the cab structure safely.

2. Component: ‘Front mudguard front support bracket assy’ (5103140-A01) – Qty 2
This (Comp 12) is the front structural brace. These two brackets anchor the front edge of the FAW J6P Three-Tier Footrest panels. They are crucial for maintaining the precise alignment and rigidity of the steps.

The structural integrity provided by these brackets ensures that the FAW J6P Three-Tier Footrest maintains its shape and security throughout the operational life of the dump truck. Failure of these internal supports would lead to a catastrophic failure of the stepping mechanism.

Core 3: The “Fastening” Logic (The Hardware System)

This final group includes the specialized, high-strength fastening hardware necessary to maintain the integrity of the FAW J6P Three-Tier Footrest structure. The fasteners must resist both shear forces and vibration.

1. Component: ‘Combination bolt’ (CQ1420625F6, CQ1460616, CQ1420620) – Qty 20, 12, and 12
This (Comp 5, 13, 15) is the primary mounting hardware. The Combination Bolt Logic ensures that the washer is permanently attached, maintaining proper clamping force distribution on the FAW J6P Three-Tier Footrest panels. The high total quantity of 44 combination bolts highlights the robust mounting required.

2. Component: ‘Large washer’ (Q40206F6, Q40206) – Qty 20 and 24
This (Comp 6, 14) is a large-diameter washer. The Load Distribution Logic ensures that the clamping force of the fasteners is spread evenly across the surface of the **FAW J6P Three-Tier Footrest** panels, preventing the bolt heads from cracking the composite material.

3. Component: ‘Cross recessed pan head screw assy’ (Q2360612F6) – Qty 8
This (Comp 7) is a self-tapping or fine-threaded screw used for securing the footrest plates (Comp 3, 4) to the inner support structure. This hardware ensures the integrated steps are securely attached to the FAW J6P Three-Tier Footrest.
