L type single beam gantry crane is matched with trolley, a kind of track travelling mid-light type crane. It is ideal for outdoor applications where lifting facilities are provided without the cost of a building or any supporting steelwork. They are also suited to indoor applications where existing building structures are not suitable to take overhead cranes, and where additional supporting steelwork would result in a loss of floor area. It can be constructed with a cantilever to allow handling outside the rail centers.
