Description
Overview:
The Mechanical Suspension Seat MGV35 With Belt by United Seats is a heavy‐duty operator seat for site dumpers and similar machinery. Finished in durable black PVC trim, it is built to handle tough, muddy, and wet conditions while remaining easy to clean. The mechanical suspension system supports operator comfort with a weight setting from 50-150 kg (110-330 lbs) and 80 mm (3.15 inches) of suspension travel to reduce jolts. A foldable, adjustable backrest helps tailor the driving position, and an integrated seat belt and contact switch support safety systems. Fore-aft positioning is simple using slide rails with 180 mm (7.09 inches) of travel, set on 328 mm (12.91 inches) centres for stable mounting. Typical uses include Thwaites and JCB dumpers where a compact, reliable seat is required.
