That depends on WHERE the rig is, because
weight = (mass) x (acceleration of gravity where the object is) .
-- If the truck is on Mars, then
Weight = (36,000 kg) x (3.71² m/s²) = 133,560N.
-- If the truck is on the moon, then
Weight = (36,000 kg) x (1.62 m/s²) = 58,320N.
-- If the truck is on Earth, then
Weight = (36,000 kg) x (9.81 m/s²) = 353,160N.
It all depends.
