What is this equipment under nose of aircraft? From the news of Singapore Airline A330 nose gear collapse at Changi, I notice an equipment is under the nose part of aircraft and somewhat damage the radome when nose gear collapse. It looks like some ladder. What is it and what is it used for?

Note: it is during routine airline operation.
The report says the aircraft was undergoing a landing gear system check. The equipment looks like a trolley-mounted inspection ladder that could well have been used during such a check.
