CAT 096-3017 SEAT

The CAT 096-3017 (0963017) is a mechanically suspended high-back operator seat assembly suitable for some medium-sized excavators and loaders. It primarily provides lumbar support and shock isolation for high-frequency vibration conditions such as mining and infrastructure work. Compatible with 320/330 series excavators and 963 tracked loaders, it includes a three-point seat belt and multi-directional adjustment, positioning itself as a durable driver’s seat solution for heavy-duty operations.

Item Details
Part Model CAT 096-3017 (0963017) Mechanical Suspension High-Back Operator Seat Assembly (including seat belt and slide rails)

Structure Type High-back mechanical spring suspension seat, including front and rear slide rails, height/backrest/lumbar adjustment mechanism, three-point automatic retractable seat belt, black wear-resistant vinyl fabric, metal stamped base + reinforced spring assembly

Material Seat cushion/backrest is high-elasticity cold-foamed polyurethane (density 60kg/m³); fabric is UV-resistant vinyl (wear resistance index ≥ 100,000 abrasions); frame is Q235 carbon steel + electrophoretic coating; springs are 65Mn silicon manganese steel, surface powder coated

Key Dimensions Seat width 460mm, total height 1120mm, seat depth 480mm, seat height 420-480mm (adjustable); front and rear slide rail travel 200mm, backrest angle 90°-125° Adjustable, lumbar support adjustment ±30mm
Adjustment functions: Forward/backward sliding (200mm), height adjustment (60mm), backrest angle (90°-125°), lumbar support (5 levels), weight adaptation (50-150kg), armrest height adjustment (50mm)
Suspension and safety: Mechanical spring suspension travel 50mm, vertical damping coefficient 0.65, suitable for high-frequency vibration conditions; three-point safety belt (length adjustable, locking response ≤0.1s), compliant with ISO 7096 vibration standard
Compatible models: CAT 320, 330 series excavators; 963 tracked loaders; some small articulated trucks (compatibility needs to be confirmed by checking the equipment serial number SN)
Weight per set: Approximately 38kg (including base, slide rails, and seat belt)
Suitable Applications
Installation Positioning: Standard four-point mounting holes on the cab floor, equipped with special bolts and anti-loosening nuts, compatible with mechanical suspension base, matching the position of operating handles and display for convenient operation.

Working Conditions: Suitable for high-frequency vibration and impact conditions such as mining and infrastructure construction. The mechanical spring suspension structure effectively isolates track travel from operational impacts, while high back and lumbar support reduce fatigue during long-term driving.

Matching Components: Compatible with seat slide rails, seat belt assemblies, and seat mounting bases; during replacement, simultaneously check slide rail wear, spring elasticity, and seat belt locking function.

Installation and Maintenance Points
Installation Steps: Clean the cab floor mounting surface, align the four-point mounting holes, and tighten with 8.8 grade M12 bolts to a torque of 60-70 N·m. After installation, test that the slide rails slide smoothly without jamming and that the seat belt locking function is normal.

Adjust the spring preload according to the operator’s weight to ensure the seat suspension travel is in the middle position, the backrest angle is adjusted to approximately 110°, and the lumbar support fits snugly against the back.

Maintenance Cycle: Inspect every 1000 hours under standard operating conditions; shorten to 500 hours under mining conditions. Focus on checking the slide rail lubrication, spring elasticity, seat belt locking performance, and fabric wear.

Replacement Standard: If the spring is broken/deformed, the slide rail is stuck, the seat belt locking mechanism is ineffective, the fabric is damaged or leaking, or the adjustment mechanism is malfunctioning, the entire seat must be replaced. If it cannot be repaired, it cannot be reused.
