Semiconductor Equipment Manufacturer Debuts "Mechanical Gravity Canceller" at Japan Truck Show 2026

The company participated in the "Japan Truck Show 2026" held at Pacifico Yokohama from May 14 to 16, where it conducted public demonstrations of the MGC (Mechanical Gravity Canceller), a manual tailgate lifter for trucks. The event concluded successfully with a high volume of industry visitors and stakeholders.

We would like to express our gratitude to all the visitors who attended our booth.

Exhibition Venue: Pacifico Yokohama ■ Featured Product: Truck Tailgate Hand Lifter MGC WTL-1000 ■ Product Name: WTL-1000

Key Features: 1) Gravity Compensation Mechanism: By "canceling" the weight of the load through mechanical counterbalancing, the system allows for cargo handling with minimal physical exertion. 2) Inclusion and Accessibility: The system enables individuals, including female operators, to lift heavy loads with ease. During the exhibition, female participants experienced the technology firsthand and provided highly positive feedback.

Event Overview: The three-day exhibition attracted a total of 66,856 visitors, including industry professionals and families. At our booth, visitors experienced the operability and functionality of the device, with many expressing anticipation for its future practical application. Notably, several bodywork manufacturers remarked that this represents a rare technological breakthrough in the power tailgate sector, leading to meaningful discussions for future collaboration.

Demonstration Performance: The demonstration showcased the lifting of 80kg of water using only one hand, without the aid of hydraulic or pneumatic power. The gravity compensation is achieved through a simple yet robust system of springs and pulleys that creates a "near-zero gravity" effect. For safety, the device remains stationary if the operator releases their grip and features an automatic lock that engages within a 5cm range in the event of sudden weight changes, ensuring worker protection. Visitors showed significant interest in the underlying mechanics, observing the spring and pulley systems closely while receiving technical explanations.

Mechanical Structure: The core technology utilizes a pulley system supported by powerful springs. While small amounts of electricity are used for the safety mechanisms and gravity point adjustment, the actual lifting force is generated purely by the spring and pulley assembly. By adjusting the pulley positions, the spring tension is modulated to maintain the load's weight at near-zero. In the commercial version, these components will be housed discreetly beneath the truck chassis.

Future Outlook: Given the substantial interest and concrete feedback received at the booth, we intend to further refine and iterate on the design in preparation for commercial release. Although our primary business lies in semiconductor inspection equipment, this project represents a commitment to a new business domain. We aim to promote the active participation of women and diverse personnel in the logistics industry by removing the physical barriers associated with heavy load handling, regardless of age or gender.
