We’ve expanded our Laser Scanning Hire Fleet with the addition of the Nedo Industrial Shaft Tripod. The Nedo Tripod is designed for raising or lowering a laser scanner to otherwise inaccessible locations and is compatible with the Leica RTC360, Leica BLK360 and Leica P Series scanners.

The Nedo Tripod enables the scanning of confined spaces such as ceilings, inspection chambers and tanks without having to deploy personnel into potentially dangerous environments. Using the  Nedo Tripod the scanner can be positioned high up to capture data on surfaces that would otherwise be shadowed by obstructions such as balconies, awnings, windowsills or other architectural details.

Christchurch City Council have recently used the Nedo Tripod in conjunction with a Leica RTC360 to scans manholes in the city. The RTC360 was inverted and lowered down into the manhole to capture 3 scan per manhole including HDR imagery for inspection purposes.

This methodology removed the need for any personnel to enter the manhole cavity and risk harm or injury to capture manual measurements or photographs in a speedy manner, cutting labour and traffic management costs.

The captured data was registered and pointclouds QA’d using Leica Register360 and then accurate 3D mesh models were produced in Leica Cyclone 3DR.

The resulting models, which were being used to design stainless-steel weir installations, providing designers with accurate and detailed digital twins of the manholes that allowed them to design and construct the inserts with a new level of confidence. This avoids potentially costly rework at the time of installation.

Each chamber, plus the surrounding area is scanned in full-HDR in approx 5 minutes. Targets incorporated into the above-ground scans enable geo-referencing of the data.

The laser scanner can be positioned to the required working height or depth at the push of a button.
