摘要：
An excavator cab is configured to have an improved field of view for three passengers. Seating is provided for an operator, a trainer, and an trainee. Persons seated in those three seats have substantially similar lines of sight. The excavator cab is arranged such that the operator seat and the trainer seat face a front observation window. The trainee seat is mounted behind the operator seat and is retractable. The points of egress and aisle are wide enough to accommodate a stretcher or a litter in case of an emergency.
