For the survey of free-standing industrial-type chimney stacks, our steeplejacks would ladder the stack and lower the camera from the top down. The video would be monitored and recorded in the survey van at the base of the stack.

The survey of chimney flues can be carried out from an Access Platform. The camera equipment can either be set up in the platform basket or cables can be run from the survey van at the base.

The highest we have surveyed chimney flues from an Access Platform is 85 metres.
