Honnor Drilling Ltd health and safety co-ordinator Bryn Shaw said he was the first worker on site around 6.30am and found the gates busted.
“I think they must have broken in [then] driven the crane truck through the gates.”
He said police contacted the business asking whether one of their employees was driving the truck, as it was seen driving erratically.
Shaw said he was pleased the police managed to locate it quickly and recover it.
“It is now back at our yard,” he said, adding it only appeared to have suffered minor damage.
He said they were assessing the premises on Friday morning to check if anything else had been stolen.
Shaw said he had been at the business for two years and had not experienced any other break-ins during that time.
