Single and Double Beam The price is based on its crane span, depending on the choice of winches and hoist by their own structural characteristics Double beam may be, two tons of electric single-girder cranes, your factory goods with 16 tons of single-girder crane is no problem, just does not start and stop time to be careful, after all, your cargo area, inertia.
