BF5-3 Mechanical Suspension Construction Seat with 60° Backrest & Optional OPS and Dust Cover

The BF5-3 mechanical suspension construction seat combines reliable suspension performance with a flexible option system, fitting small-to-medium excavators, wheel loaders, motor graders, aerial work platforms, and other types of construction equipment. Its built-in mechanical suspension system provides 40mm of suspension travel paired with 45–120kg weight adjustment, effectively cushioning jobsite bumps and operational vibration to reduce operator fatigue during long shifts. The backrest adjusts through a wide 60° range (-35°~+25°) and, combined with 75mm of slide travel in each direction, can be flexibly positioned for digging, loading, grading, and other working postures.

A retractable seatbelt and document box come standard, covering basic safety and storage needs. Optional configurations are available to order: Option A OPS micro switch for operator presence safety detection, meeting equipment safety regulations; Option B dust cover that blocks dust and debris, protecting internal seat mechanisms for dusty jobsite environments. The universal multi-hole mounting base is compatible with 230×280, 280×280, and 330×280mm hole patterns for flexible installation across equipment. Buyers can choose between black backed PVC (outdoor durable and easy to clean) or flannelette (breathable comfort for enclosed cabs). All materials pass ISO9001 ,CE and EN13490 IT+IT2 related testing. Configurable to equipment positioning and application scenarios, it is a cost-effective suspension seat choice for construction fleets and equipment manufacturers.
