BF17 Heavy-Duty Mechanical Suspension Construction Seat with Ultra-Wide Backrest Recline & Broad Weight Compatibility

The BF17 is a heavy-duty mechanical suspension seat with extra large backrest tilt, designed for high-load construction machinery including large excavators, loaders, road rollers, mining carriers and heavy aerial work platforms to improve riding comfort during prolonged intensive work. The backrest provides an 80° adjustment range from -30° to +50°, with lockable positions within the 35° regular working zone; operators may stay upright during operation or recline significantly to relieve lumbar strain during short breaks. Extended slide rails offer 110mm forward and 90mm rear travel for abundant seating adjustment. You can pick 60mm or 80mm suspension travel, alongside an expanded 45–170kg weight adjustment range to accommodate heavier operators and dampen vibration from uneven job sites effectively.

Standard hardware includes an emergency locking two-point seatbelt and driver presence micro switch for mandatory safety control; an optional document box (Option F) is available for storing work paperwork. The standard 328×285mm mounting footprint fits universal multi-hole bases with common hole layouts of 230×280, 280×280, 330×280. Reinforced backed PVC upholstery resists tear, oil and dirt for outdoor dusty worksites, while flannelette delivers softer breathable seating for enclosed cabins. All fabrics pass ISO9001 and CE tests for abrasion, flame and UV resistance. Optional integral-skin PU foldable armrests can be installed, making this seat suitable for OEM integration and bulk fleet replacement for heavy construction equipment.
