C-ALS® HD SYSTEM
Complete High-Definition Survey System
£76999.00
The Carlson Cavity Auto-Scanning Laser System High Definition, CALS ® HD, is equipped with a hi-definition nosecone camera with a 874-lumen daylight payload. The new system is capable of 360° scans in underground cavities and rugged environments for observations, mapping, risk assessment and more. The C-ALS HD, with a probe diameter of 50mm (1.96 inches) is deployable though boreholes as small as 76mm (3 inch) and offers versatile deployment options in downward, upward, and horizontal directions. The C-ALS HD incorporates a 3-axis gyroscope alongside the pitch and roll sensors to provide greater azimuth accuracy, thus eliminating the traditional “Boretrak® Rods” needed for maintaining azimuth reference in past non-gyro versions. Using the new slip ring cable drum, the C-ALS HD user is now able to deploy the system more efficiently and quickly than the traditional spool only cable configurations that required the deployable length of cable to be unspooled before connecting the
system to it.The C-ALS® HD SYSTEM includes all necessary components for high-definition underground surveys. It comes equipped with a stainless steel C-ALS HD Probe, a standard extension piece, and various essential accessories such as calibration jigs with survey prisms, battery packs, chargers, cables, and control units with Wi-Fi. This system is designed for robust fieldwork and includes a comprehensive transit case and a USB drive with Carlson Scan software and manuals.
C-ALS Applications
Monitor excavations, assess risk, or design solutions Utilise the Carlson C-ALS system when a complete picture of the situation underground is needed. Identify, measure, and map voids below construction or geotechnical projects to help avoid/prepare for differential settlement, sinkholes, or even catastrophic collapse of old mine workings or voids that may underlie residential and commercial properties. With the complete picture the C-ALS system provides, engineering solutions can then be put into place to counter the problems.
The C-ALS system can be used in a huge range of applications where an inaccessible void exists and accurate data is required, including:
• Subsurface voids and cavities
• Underground chambers and tanks
• Ducts
• Inaccessible roof spaces
• Stopes
• Ore passes
• Collapsed mine workings
• Culverts
• Shafts and bunkers
• Underground caverns
• Industrial production facilities with limited or unsafe access
Support underground or surface mining projects
By using C-ALS to determine the size, extent, and status of inaccessible voids, mining customers get a complete picture of the situation underground before committing to projects or deploying workers. In addition, a full understanding of the layout of underground workings and their relation to surface operations is also essential for safe open-pit operations using heavy machinery, explosives, and personnel.
The C-ALS system provides a detailed visual record of the following:
• Excavation and infill of stopes
• Location of voids
• Geometry and condition of mine workings
• Inaccessible historic workings
• Collapsed areas, sinkholes, and troughs
• Erosion of ore passes
• Volumes of voids
• Position of cavities in relation to other underground workings and structures
• Size and location of remaining pillars
• Location of the voids/workings relative to surface features
C-ALS® Software
Carlson’s software for C-ALS makes it easier and quicker for operators to learn and use the system by guiding them through the process of deploying and scanning to enable:
• Quick navigation and intuitive design for both new and experienced operators, both reducing training needs and improving efficiency
• “Seeing” the heading and inclination of the C-ALS probe at all times
• One-click surfacing and volume calculation from raw scan data for the production of closed 3D model and volume within seconds of finishing a scan
• Point cloud editing and visualization on site
• Swifter setup time due to auto-connection to the C-ALS probe
• Saving and sharing of video footage with live recording from the C-ALS camera into WMV
• Easy integration with third-party processing software packages with ability to export to many industry-standard formats, including LAS and DXF
