A ‘prime mover’ is a truck with a robust engine that can haul bulky loads on trailers for long distances and are also referred to as “heavy-duty trucks” or “trailer trucks”. A prime mover can tow up to 50 tons of using its strong pulling power. Every day, tens of thousands of containers are moved on and off vessels and through Singapore’s port terminals. Our prime mover drivers play a key support role in Singapore’s vibrant international trade, by driving the prime mover trucks to transport containers from the wharves to the yards, and vice versa.
