Semi-automatic sluice gate opening and closing machine "Rakusho II"

Semi-automatic sluice gate opening and closing machine "Rakusho II"

It's a simple task to fix the main body of the Rakusho to the handle! It was born from the voices of those engaged in high-load work.

"RakuSho II" is a semi-automatic sluice gate opening and closing device that does not require a power supply. It is a simple task to fix the main unit to the handle (one device per sluice gate), allowing for the opening and closing of multiple sluice gates without fatigue using just one rechargeable driver and a spare battery. Even during power outages in emergencies, it can be operated as long as it is charged, and if the rechargeable driver cannot be used, it can be opened and closed manually with a dedicated manual handle (for RakuSho II), providing peace of mind. 【Features】 ■ Simple task of fixing the main unit to the handle ■ Allows for the opening and closing of multiple sluice gates without fatigue using just one rechargeable driver and a spare battery ■ Operable during power outages in emergencies as long as it is charged ■ Can also be opened and closed manually with a dedicated manual handle (for RakuSho II), providing peace of mind *For more details, please refer to the external link page or feel free to contact us.

Remote control system for monitoring the opening and closing of sluice gates.

Remote control system for monitoring the opening and closing of sluice gates.

Remote monitoring and control via smartphone! Since it can be retrofitted to existing sluice gates, installation costs can be kept down! "Sluice Gate Opening and Closing Monitoring Remote Control System"

Recently, there has been an increasing trend in natural disasters, particularly with frequent damage and accidents caused by heavy rainfall. The water level situation due to heavy rain is concerning, but conducting on-site water level checks and gate operations is extremely dangerous. **Problems with Water Level Monitoring and Manual Gate Operations During Heavy Rain** - On-site confirmation is necessary, making rapid response difficult and posing risks of exceeding dangerous water levels and river flooding. - Upgrading to automated gates incurs costs. - Manual gate operations with hand cranks are time-consuming and place a significant physical burden on workers. **Solution through Remote Control System for Gate Monitoring and Operation** - The status of river channels and gate operations can be monitored remotely (via PC or smartphone), allowing for rapid response as part of disaster prevention measures and flood mitigation. - Automation of gate operations can be achieved with the "Gate Bot," which can be retrofitted to existing equipment, enabling quick and cost-effective implementation by utilizing current infrastructure. - Compared to manual operations, the time for gate opening and closing and the physical burden on workers are significantly reduced. If you are feeling uneasy about your current equipment or are considering the introduction of a monitoring and control system, please feel free to consult with us.

Integrated management bridge-type falling gate

Integrated management bridge-type falling gate

A gap meter has been installed on the management bridge deck to allow for a quick understanding of the gap condition.

Our company handles the "Management Bridge Integrated Tilt Gate," which does not require land outside the waterway. By eliminating structures on the ground, we can use the waterway as a road, and the concrete work for the installation can be minimized to just the drop structure for the gate body, resulting in reduced construction time and costs. Additionally, the opening and closing operation uses a detachable lightweight crank handle (R150), which allows for clockwise rotation to raise and counterclockwise rotation to tilt, stopping at any desired position for easy water flow adjustment. [Other Tilt Gates] - Solar-powered automatic tilt gate - Automatic tilt gate with a simple power device - Tilt weir (FGL-75) *For more details, please download the PDF or contact us.
