  When using the Extenor Ⅱ
Cumulative work time Approx. 60 min × 4 workers (4 hours) / 1 container
4 hours × 100 containers per month = 400 manhours saved per month (4,800 per year)
Annual labor costs ¥1,000 per hour × 4,800 hours = ¥4.8 million saved
Number of workers Assuming 1 worker earning ¥1,000/hour is eliminated
¥1,000 × 10 hours × 20 days × 12 months = Annual ¥2.4 million saved
Equipment cost Equipment cost     ¥4 million (standard specification)
Depreciation C 400/720 = in approx. 7 months
* ¥4.8 million (labor cost) + ¥2.4 million (workers) = ¥7.2 million
Leasing ¥4 million × 1.4% = ¥56,000 per month (¥6.72 million per year)
Notes Calculations do not include costs for connected conveyors.
