高知丸高 List of Products and Services

We would like to introduce the work vessels we own. We have a "Unifloat modular barge" used for marine transportation (steel materials), as well as a "river port coastal work barge" used for steel pipe pile driving construction, and an "amphibious excavator" used for dredging works. Additionally, we also have a "modular self-propelled boat," a "rescue boat Beaver," "tugboats and anchor handling vessels," and "bridge inspection and repair debris recovery boats." 【Owned Work Vessels】 ■ Unifloat modular barge ■ River port coastal work barge ■ Amphibious excavator ■ Modular self-propelled boat *For more details, please refer to the PDF document or feel free to contact us.

The "Ultra High Frequency Variable Hydraulic Vibratory Pile Driver" complies with the exhaust gas standards of the "Off-Road Method" implemented in 2006 and meets the third-level criteria, making it a pile driver that does not burden the natural environment. As a pile driver that operates at even higher frequencies than conventional hydraulic variable ultra-high frequency types, it is a countermeasure model that meets the noise standards (85dB) and vibration standards (75dB) set by the Ministry of the Environment. Additionally, it is capable of driving piles into hard ground with its extremely high driving force. 【Features】 ■ NETIS registered ■ Ultra low noise, ultra low vibration, and exhaust gas countermeasure construction machinery ■ Driving force and lightweight design ■ Application-specific clamp heads ■ Variety of pile selections *For more details, please refer to the PDF materials or feel free to contact us.

• Foundation construction machinery
• Pile and foundation work

Since our establishment, we have been active in the field of foundation work and have been engaged in the development of construction technologies that respond to societal needs. In particular, we have achieved numerous results and accomplishments in construction under special conditions and rock drilling work. Additionally, we are also working on research and development of disaster prevention-related products in response to the increasing frequency of natural disasters. We are expanding our business broadly in areas such as civil engineering, foundation work, bridges, and disaster prevention products. 【Business Overview】 ■ Special Foundation Work - Large-diameter rock drilling - Bridge construction and fabrication - General civil engineering - Marine and port construction, dredging - Vessels - Piling work - Disaster prevention products, etc. *For more details, please refer to the PDF materials or feel free to contact us.

• Special Construction Method

The "SqC Pier Method" is a construction method for steel pipe bridges that reduces high-altitude work and achieves safer construction. By using this method, it is possible to improve quality through a reduction in on-site assembly work and shorten construction periods due to improved workability. Please feel free to contact our company for inquiries. 【Features】 ■ Selected as a recommended new technology by the Ministry of Land, Infrastructure, Transport and Tourism ■ Reduction of high-altitude work ■ Achievement of safe construction ■ Improvement in quality ■ Shortened construction period *For more details, please refer to the catalog or feel free to contact us.
