ODT009810296 Rear Frame Assembly Sany SAT40C Articulated Dump Truck Spare Parts

ODT009810296 Rear Mainframe Trailer Chassis Assembly for Sany SAT40C

The ODT009810296 Rear Frame Assembly (Rear Mainframe Trailer Chassis Group) is the primary heavy-duty load-bearing chassis structure designed for the rear trailer section of the Sany SAT40C articulated dump truck. Articulated dump trucks operate under continuous, heavy structural shock loads in muddy, high-moisture, and dusty open-pit mines. The rear mainframe (ODT009594364) bears the direct mechanical stresses from the fully loaded dump body (bin), high-thrust hoist tipping cylinders, and middle/rear tandem drive axles. This structural group comprises the main heavy welded carriage structure, integrated centralized lubrication lines, limit detection switches, damping plates, and high-strength fasteners.

This group integrates the primary high-strength low-alloy structural steel welded Rear Carriage Assembly (ODT009594364), ten heavy-duty structural Damping Plates (ODT005878700), and a comprehensive, built-in centralized lubrication line network. This pre-plumbed auto-grease line system utilizes oil cups, connection joints, and high-pressure resin tubes to feed grease directly from the central auto-greaser to the high-load tandem suspension pivot bushings, keeping dirt out and preventing metal wear. For tipping protection, it incorporates mechanical Limit Levers (ODT005935545) and a Limit Switch Seat (ODT005935550) to housing the body limit switch, protecting the hoist hydraulic cylinders from over-travel. Over 80 adjustable shims (items 17, 18, 33, and 34) are provided to calibrate internal clearances, eliminate structural backlash, and align high-stress suspension blocks. We supply the fully integrated ODT009810296 rear frame group, individual frame weldments, brackets, limit switches, and hardware. Both genuine Sany OEM kits and highly reliable aftermarket options are in stock for rapid international shipping.

Features & Benefits of Our Rear Frame Assembly Group

• Heavy-Section Welded Steel Construction: The Rear Carriage Assembly (ODT009594364) is fabricated from premium structural-grade, low-alloy steel plate, designed to bear full payload weights, hoist cylinder thrusts, and rear axle forces.
• Integrated Centralized Automatic Lubrication: Pre-plumbed with high-strength resin tubes (items 29, 31, and 32), oil cups (item 26), and connection joints (items 27 & 28) to route high-pressure grease directly from the auto-greaser to the tandem suspension pivot bushings, keeping dirt out and preventing metal wear.
• Electrical Limit Switch Protection: Incorporates a Limit Switch Seat (ODT005935550) and Limit Levers (ODT005935545) designed to housing and actuate the body limit switch, protecting the hoist hydraulic cylinders from over-travel.
• Structural Damping & Vibration-Resistant Shimming: Features ten heavy-duty Damping Plates (ODT005878700) and over 80 pre-cut structural shims (items 17, 18, 33, and 34) designed to distribute the clamping force evenly across the structural joints, preventing mechanical cracking from engine block and frame vibrations.

Ordering & Technical Maintenance Guidelines

1. Verify Chassis Drivetrain and Rear Carriage Lengths: Main trailer frames and supporting beams can undergo minor layout modifications depending on regional emissions regulations. Please provide your Sany SAT40C articulated dump truck’s chassis serial prefix so our technical team can verify exact part compatibility.
2. Regularly Clean Out Accumulated Debris: Articulated dump truck rear carriages operate in high-dust and muddy conditions, allowing clay, sand, and rock chips to gather in the frame pockets. Power-wash the chassis regularly during PM servicing to keep automatic greaser lines and limit switch linkages free of binding debris.
3. Observe Fastener Torque Specifications: Drivetrain and chassis mounting hardware are subject to immense mechanical stress. When refitting brackets or shims, ensure all bolts are torqued according to Sany’s specified values to prevent thread stripping.
