BF5-2 Wide-Range Adjustable Backrest Construction Seat with Universal Multi-Hole Base & Dual Fabrics

The BF5-2 construction machinery seat centers on a wide 60° backrest adjustment range, with the backrest supporting -35° to +25° angle adjustment. It can be flexibly positioned for different operating postures across digging, loading, grading, and other tasks, adapting to diverse construction work scenarios. The slide rail offers 75mm of travel in both directions and, combined with the wide backrest angle range, accommodates personalized seating positions for operators of different sizes.

A retractable safety belt and document box come standard, covering work safety and personal document storage with core functionality ready out of the box. The universal multi-hole mounting base features pre-drilled patterns including 230×280, 280×280, and 330×280mm, directly fitting light excavators, wheel loaders, motor graders, small lifting equipment, and other construction vehicle types for straightforward installation. Two fabric options are available: black backed PVC for tear resistance, water and oil resistance, suited to outdoor open-air jobsites; and flannelette, breathable and soft, recommended for enclosed cab machines. An optional OPS microswitch (Option A) can be added for operator presence safety detection to meet equipment safety regulations. All fabrics and core components pass ISO 9001 and CE related testing for consistent, reliable quality.
