Partially are they used own equipment like this Liebherr LR 1280 on a new tunnel under construction in Sydney (AU). John Holland deploys multiple units Liebherr LR 1280.
The undercarriage is 9.08 meters long and 7.5 meters wide. The tracks are each 9.08 meters long, 1.2 meters wide and 1.46 meters tall. They have to be removed for the transport over the road and have a mass of 20 tonnes each. Between the tracks are in total 36 tonnes of central counterweights.

Attached to the superstructure is 85.5 tonnes of counterweight mounted, the counterweight has a 6.215 meter tailswing.
The crane was fitted here with a 60.8 meter long main boom. The maximum length of the main boom is 90.2 meters.
Attached to the main boom head is an auxilairy jib so that the crane can work with two hooks. The auxilairy jib has a maximum capacity of 30 tonnes.
During my short visit was the crane busy lifting multiple smaller containers with soil from the pit. A very sharp crane of John Holland!
