“We are not just lending equipment to our customers. Together we examine problems they have at their construction sites and help them solving the problems.” This is our theme. 
Machinery Corporation, we have mainly focused on the process and sales of crane wire ropes for 52 years since the establishment in 1958. Today, we have expanded our products and services, and grown into a company that offers comprehensive rental and sales services of temporary materials used at construction sites.
Our motto is to be the company that can assist our customers to solve the problems they have at their construction sites through our new products and ideas and to be a healthy company.
While the interest in the environment has been growing, fact that about 70% of the industrial waste is trash and waste generated by construction sites has become a major issue. To help solving the issue in some way, we consider setting a course for waste reduction by providing reusable and recyclable products as one of our major businesses.
“Slide-Panel” is the product that fits the purpose and widely used by many of our customers. We will work hard to satisfy our customers and pursue to be a company that can bring happiness to our employees.
