Company information
Leave the assist transport equipment, electrical equipment, and industrial equipment to us.
At Yamaiichi Seiko Co., Ltd., we are engaged in a business primarily focused on the development, manufacturing, and sales of assistive devices. If you are having trouble with heavy lifting or wish to improve heavy load transportation, please feel free to contact us. We have demo units and rental units available for all models. Additionally, we can consider the production of custom products as per customer requests. Our assist units are designed to be set on the customer's cart (Unit Type: 01: Fixed Type, 02: Detachable Type). This is ideal for customers who do not want to increase the number of carts but wish to assist their existing carts.
