A hydraulic-excavator backhoe is excavating the basement for a building. Heaped bucket capacity is 1.10 mº. The material is common with a bucket fill factor of 0.90. Job efficiency is 53 min/h. Average depth of cut is 2.7 m. Maximum depth of cut is 9.0 m and average swing is 75 degrees. Estimate the hourly production in bank measure.
