6. De steam crane (road engine).

Another type of road engine is the steam crane. The crane engine, could be described as a roadloco equipped with a jig and was used on shipyards, constructionworks, sawmills etc.
In many cases the jig is removable and than the engine could be used as an ordinary road loco.
On old photographs you see them often used in sawmills to hoist the trees on the sawbench.
Pictures made on shipyards show the importance to help the workers in transporting heavy loads. Before the crane engine was developed only cranes on rails, so a partially “fixed” move was available and muscleforce! The strong point of the crane engine is its mobile application.
Sometimes you can see them on steamrallies.
