Performance Parameters: Rated load ≤130 kg, mechanical suspension damping efficiency ≥60%, seat belt tensile strength ≥22 kN, fabric abrasion resistance ≥40,000 cycles, corrosion resistance IP54, applicable temperature -20℃ to +60℃

Compatibility Standards: Complies with CAT seat specifications, ROPS/FOPS certified, seat belt conforms to SAE J386 standard, damping performance meets ISO 7096 requirements

Matching Components: Includes seat assembly, mounting base, seat belt assembly, adjustment handle, and CAT cab seat mounting holes.

Compatible Models and Application Scenarios:

Compatible Equipment: Cabs for CAT 312/315 series excavators, 950/966 series loaders, small bulldozers, and other small and medium-sized construction machinery.

Application Scenarios: Heavy-duty, high-vibration conditions such as mining, infrastructure, and road construction, providing stable support and a comfortable driving environment for operators working for extended periods, reducing fatigue.

Installation: Directly installed onto the cab seat rails and secured with bolts, requiring no additional modifications. Compatible with standard CAT cab interfaces.

Installation and Maintenance Points:

Before installation, clean the seat rails and mounting surface. Inspect the seat for deformation and damage, and check the seat belts for aging and cracks.

Align the seat with the rail positioning holes and tighten with M10 bolts to a torque of 35-40 N·m, ensuring a secure and tight fit.

Adjust the seat’s fore-and-aft position, height, and backrest angle so that the operator can easily operate the control levers in a natural sitting posture, and the lumbar support conforms to the lumbar curve.

Maintenance: Check the suspension spring elasticity and shock absorber damping every 500 hours; replace immediately if any are faulty. Use a neutral detergent to clean the fabric; avoid using corrosive solvents. Inspect the seat belts every 2000 hours; replace immediately if aged or damaged.
