330104129 Hydraulic Elevator Assembly XCMG XDE130 Dump Truck Parts

330104129 Hydraulic Elevator Assembly for XCMG XDE130

The 330104129 Hydraulic Elevator (widely known in the mining industry as the Automated Boarding Stairs or Power Access Ladder) is a critical operator safety and access system designed for the XCMG XDE130 Electric Driving Dump Truck. On 130-ton ultra-class haul trucks, the operator cabin is located several meters above ground level. This complex mechanical linkage system uses hydraulic power to lower the stairs for safe, angled boarding, and retracts them flush against the chassis during operation to prevent collision damage from rocks, berms, and loader buckets.

This comprehensive 31-part master assembly contains the entire structural folding mechanism. It features the heavy-duty welded support frame, four independent linkage rods, greasable pivot pins, impact-absorbing cushions, and highly visible anti-slip mats. It also includes the mounting plates for the proximity sensors, which alert the vehicle’s ECU when the stairs are safely retracted. We supply the complete 330104129 assembly as a drop-in replacement, as well as individual structural sub-components for targeted collision repair. Genuine XCMG OEM parts and premium aftermarket alternatives are available for global dispatch.

330104129 Component Parts List (Master Table)

Below is the detailed 31-part breakdown of this retractable stairway assembly according to the official XCMG XDE130 parts catalog. You can order the entire fully-assembled unit or request specific individual hardware components (such as pins, links, or anti-slip mats):

Features & Benefits of Our XCMG Access Systems

• Engineered for Safety Compliance: The complete inclusion of high-grip Anti-Slip Mats (Indexes 25 & 26) provides operators with secure footing in wet, icy, or muddy mining conditions, strictly adhering to MSHA and OSHA fall-protection mandates.
• Heavy-Duty Articulation Mechanism: The stairway folding action is controlled by a network of forged Link Rods (Indexes 4–7) and heavy-duty pivot Pins (Indexes 8–11). These feature integrated M10x1 Grease Zerks (Index 16) to ensure the folding mechanism remains lubricated and bind-free over thousands of cycles.
• Integrated Electronic Safety Sensors: Features exact-spec Proximity Switch Plates (Indexes 27 & 28). These brackets securely hold the magnetic position sensors that alert the truck’s ECU when the stairs are safely retracted, preventing the truck from being driven with the ladder deployed.

Ordering & Logistics Guidelines

1. Select Individual Components: Due to the massive scale of this 31-part structural assembly, customers frequently order specific replacement parts. Please clearly specify if you need the entire stairway framework, or just an individual sub-component (e.g., “Index 4: 330104269 Link Rod” or “Index 25: 330105481 Anti-Slip Tread”).
2. Provide Machine Serial Number: Proximity sensor mounting locations and linkage geometries can vary based on specific chassis and cabin configurations. Providing your XCMG XDE130 VIN ensures our technicians supply 100% accurate, plug-and-play fitment.
3. Global Heavy Freight Shipping: Structural steel boarding stairs are bulky and susceptible to bending if handled improperly. We utilize specialized flat-rack containers and custom protective crating to ensure these critical safety structures arrive undamaged at your repair facility.
