High Altitude Balloons might work on the Moon.
High-altitude balloons are crewed or uncrewed
balloons, usually filled with
helium or
hydrogen, that are released into the
stratosphere, generally attaining between 18 and 37 km (11 and 23 mi; 59,000 and 121,000 ft) above
sea level. In 2002, a balloon named BU60-1 reached a record
altitude of 53.0 km (32.9 mi; 173,900 ft).

Any object the Moon, above 750 miles, starts to experience a gravitational tug of war with the Earth.
A High Altitude Balloon could be deployed at normal operating altitudes that the balloons are on Earth, attached to a rail road type of track, lifted into Lunar altitude using thrusters that would then also pull the balloon and cargo along the track to any place within range of the main base and as far as the track could be laid.
Im not certain if the hydrogen or helium would stay inflated though due to extreme cold or lack of the Moon having an atmosphere to trap heat between the clouds and surface.
The Moon isn't bouyant enough for a helium balloon to operate on the Moon, it would oxygen.
Perhaps a clear shell around the helium or hydrogen balloon could provide the necessary buoyancy. With oxygen between the outer balloon and the helium balloon, the helium balloon would have the atmosphere needed to float.
Ill go ask NASA if the vaccuum chamber is able to be used for such a test.1
