Summary and features

Robotic Movement (half-automatic, single-operator)

Using an adhesion pad, this robot-ized system carries corrugated cartons stacked in the container from back front.

Operable by all kinds of workers

So easy to use, the Extenor makes it possible to do the formerly labor-intensive work of unloading with just a single worker (and makes the work easier for those with less physical strength or stamina).

  When using the Extenor Ⅰ
Cumulative work time Approx. 90 min × 4 workers (6 hours) / 1 container
6 hours × 100 containers per month = 600 manhours saved per month (6,000 per year)
Annual labor costs ¥1,000 per hour × 6,000 hours = ¥6 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     ¥30 million (standard specification)
Depreciation C 840/3000 = in approx. 3 years 7 months
* ¥6 million (labor cost) + ¥2.4 million (workers) = ¥8.4 million
Leasing ¥30 million × 1.4% = ¥420,000 per month (¥5.04 million per year)
Notes Calculations do not include costs for connected conveyors.
