A trailer with crane (also known as a crane trailer or lorry-mounted crane trailer) is a mobile lifting and hauling combination consisting of a towing vehicle (or tractor unit) and a trailer equipped with an integrated hydraulic crane. This configuration allows for self-loading and unloading of heavy cargo, pipes, construction materials, or equipment directly onto the trailer bed without requiring an additional lifting machine. The crane is typically mounted on the front or rear section of the trailer and can rotate, extend, and lift loads ranging from a few tons to over 30 tons. Trailer with crane is widely used in construction sites, logistics yards, pipeline projects, utility maintenance, and material handling ap
