- Cost Savings in Shotcrete: Robotic shotcrete machines reduce the amount of labor required for projects, lowering labor costs. Additionally, the precision of these machines minimizes material waste, resulting in significant savings on raw materials.
6. Remote-Controlled Operations
One of the standout features of robotic shotcrete machines is their ability to be operated remotely. Remote-controlled operations offer several advantages in terms of safety, flexibility, and precision:
- Cordless Remote Operation: Operators can control the robotic shotcrete machine from a safe distance using cordless remote controls. This eliminates the need for workers to be physically present in hazardous areas like tunnels, mines, or unstable construction zones, thereby reducing the risk of injury.
- Flexible Operator Positioning: The flexibility provided by remote operation allows operators to choose vantage points that offer the best visibility and control, further enhancing the accuracy of shotcrete application. This also ensures the comfort and safety of workers, as they can remain in safer, less exposed positions during operation.
Remote-controlled operations not only enhance the safety of the construction process but also improve efficiency by allowing workers to manage the machine from the optimal position without being limited by physical proximity.
7. Environmental and Safety Benefits
Robotic shotcrete machines offer several environmental and safety benefits that make them an attractive option for modern construction projects:
- Environmental Impact Reduction: By optimizing the shotcrete application process, robotic machines reduce the amount of concrete waste and limit the environmental impact of construction. The precise spraying technology ensures minimal overspray, reducing the excess material that often ends up being discarded in traditional methods.
- Geohazard Mitigation: In geohazard-prone areas such as unstable slopes or earthquake zones, robotic shotcrete machines can quickly apply stabilizing concrete layers to prevent landslides or structural failures. This proactive approach helps to reduce the risks associated with natural disasters and unstable terrain.
- Safe Shotcrete Application: With their ability to operate in dangerous environments, robotic shotcrete machines significantly reduce the need for human workers to be in harm’s way. The safety protocols integrated into these machines, such as automatic shut-off features, add an extra layer of protection during operation.
By minimizing the environmental footprint of construction projects and improving worker safety, robotic shotcrete machines align with both sustainability goals and stringent safety standards.
