Super Bigger Method

It is possible to perform construction with low vibration and low noise by using static pressure from hydraulic pressure to break rock!

The "Super Bigger Method" is a technique for breaking and crushing hard rock and concrete structures with low vibration and low noise. It is particularly effective for construction near safety-related properties, as there is less risk of flying debris. The crushing pressure can reach 3,400 tons, making it possible to reliably crush hard rock. Additionally, it can be operated with a 0.8m³ class power shovel, allowing for rotation during movement and setup, making it highly versatile even in narrow spaces. If a separate hydraulic power source is provided, it can also be suspended and operated with a crane. 【Features】 ■ Can crush with low vibration and low noise ■ Suitable for crushing from medium hard rock to hard rock ■ Mounted on a general-purpose shovel (0.7m³), adaptable from narrow to wide spaces ■ Continuous operation possible with a small bench cut method *For more details, please refer to the PDF materials or feel free to contact us.

Bridge Demolition Case Study: Upper Structure of the Shinkawajiri Bridge (Old Bridge)

Bridge demolition using blasting. It significantly reduces dangerous tasks such as high-altitude work and the rigging of heavy objects.

A bridge spanning National Route 417 in Ibi River Town, Ibi District, Gifu Prefecture. With the opening of a bypass due to the development of new tunnels and bridges, the Shinkawajiri Bridge (the old bridge), built in 1961, has completed its 60-year service and was dismantled using blasting methods. - Structure: Steel Langer Bridge - Bridge Length: 136.7 m - Width: 5.5 m - Weight: 223 tons On both sides of the bridge, steel components were cut using V-shaped blasting lines and dropped directly onto a work platform created on the riverbed of the Ibi River, facilitating safe mechanical dismantling on the ground. [Features] - Elimination of the need for large-scale scaffolding, leading to reduced construction time and cost savings. - Significant reduction in high-altitude work that poses risks of falling. - Major reduction in hazardous work associated with lifting heavy objects. - No special equipment required due to gravity-based dropping. - The shape after dropping is relatively stable, allowing for smooth subsequent mechanical dismantling. *For more details, please refer to the PDF document or feel free to contact us.*
