With the recent labor shortage due to the retirement of a large number of craftsmen, ATOUN MODEL K was developed to heighten productivity onsite.

Reducing Necessary Personnel by 50%


The usual number of workers for bar arrangement is 6~7. Using power assist arm makes the task possible with 3 people: 1 operator and 2 rebar workers.

Enabling Intuitive Operation


For bar arrangement, grasp a rebar with the gripper and press the hoist button to lift it.
The servomotor also works in sync with movements of the grip which can be operated with one hand.

Enhancing Human’s Right Arm


Consisting of elements resembling the human’s right shoulder, upper arm, elbow, forearm, and hand, along with a control panel and two more supporting motors, ATOUN MODEL K can move similarly to a human right arm.

Simple and Smooth Installation


Each part for assemblage weighs approximately 40~60 kg.
Manual assembling and dismantling by 3 people can be completed in 20 minutes.

Case Study

ATOUN MODEL K is a collaborative effort by SHIMIZU CORPORATION and SC Machinery. With the purpose of heightening onsite productivity that follows the i-Construction policy by the Ministry of Land, Infrastructure, Transport and Tourism of Japan, it is now being used at Tokyogaikan Expressway’s Owada construction site.
