Operator Seating: Design Trends and Requirements for Earthmoving Equipment

This up-to-date review of dimensional requirements and necessary adjustments for operator seats on earthmoving equipment is consistent with the most current information regarding operator size range. A significant improvement incorporates full-foam cushions and molded covers, with cushion firmness and damping specifications. Particular emphasis is also placed on a recent manufacturing method wherein the polyurethane foam of the seat cushion is integrally bonded within the molded cover so as to provide numerous benefits. Finally, as a measure to protect operators from prevalent shock and vibration, increased usage of suspension seating rather than simple seat cushions is recommended.
