The CAT 5K-1065 is a Caterpillar original equipment manufacturer (OEM) mechanical suspension operator seat assembly, suitable for the cabs of road rollers, loaders, bulldozers, and equipment powered by engines such as 3116/3126/3306/3406. It emphasizes vibration resistance, multi-directional adjustment, and durability, making it suitable for long-term high-frequency vibration conditions.
Core Technical Parameters
Item Details
Part Model: CAT 5K-1065 Mechanical Suspension Seat Assembly (including seat cushion, backrest, mechanical suspension, seat belt)
Material: High-density foam sponge + wear-resistant fabric / artificial leather; metal suspension frame + powder coating for rust prevention; engineering plastic adjustment parts
Key Dimensions: Seat width approx. 460mm, backrest height approx. 750mm, total height approx. 1000mm; fore-aft adjustment travel approx. 150mm, vertical suspension travel approx. 50mm (subject to actual product and manual)
Compatible Models: Road roller 815B/826C, loader 930K/950K, bulldozer D6/D7, engine 3116/3126/3306/3406. Supporting equipment for the operator’s main seat in the cab.
Performance Characteristics Mechanical spring suspension filters vibration, reducing fatigue; backrest angle, seat height, and fore-aft position are adjustable; integrated three-point safety belt adapts to harsh working conditions.
Structure and Core Functions
Vibration Isolation: The mechanical spring suspension system filters high-frequency vibrations during equipment operation, reducing pressure on the operator’s lower back and spine, and improving comfort during long working hours.
Ergonomic Support: High-density foam provides lumbar and back support, reducing muscle strain; the fabric is wear-resistant and stain-resistant, suitable for dusty and oily construction environments.
Safety Protection: The three-point safety belt secures the body, preventing accidental collisions caused by equipment vibrations during operation, ensuring operational safety.
Multi-directional Adjustment: Fore-aft, height, and backrest angle are adjustable to adapt to operators of different sizes, optimizing operating posture and visibility.
Installation and Maintenance Points
Installation Specifications: Clean the cab seat mounting base, check the bolt hole position and size, and ensure they match the seat mounting holes.
Use dedicated bolts for fastening, with torque as specified in the manual (approximately 35-45 N·m) to prevent loosening. After installation, test the smoothness of the fore-and-aft sliding and suspension functions.
Check that the seat belt anchor points are secure, the locking mechanism is functioning properly, and there is no jamming or loosening.
Maintenance Recommendations: Every 500 working hours, check: suspension springs for deformation or breakage, adjustment mechanism for flexibility, bolts for looseness, and fabric for damage.
Regularly clean the seat surface to remove oil and dust; apply grease to moving parts of the suspension to maintain smooth adjustment.
If spring failure, fabric damage, or abnormal seat belt locking is found, replace the corresponding part or the entire seat immediately.
