The term 'PORT OPENER' can be solved by two four-letter words: TELE and HELI. TELE stands for telehandler, which is a type of machine used to move materials around a construction site or warehouse. It is also known as a forklift or a reach truck. HELI stands for helicopter, which is an aircraft that uses rotors to lift off the ground and fly. Helicopters are often used in search and rescue operations, as well as for transporting goods and people.
