Реферат: The crane has one or more lifting crabs travelling along it, also travel gear at the ends by menas of which it moves sideways on tracks. The gantry (2) is shorter than the clear space (LA) between the tracks (10), and the travel bogies (5) are retractable from supporting positions on the tracks beyond the gantry ends to others inside them. There are jacks (11) near each end of the gantry, adjustable for height and with travel bogies (12) at their lower ends. These bogies can be so arranged as to allow the gantry to travel in the lengthwise direction, or sideways, and can slew on the jacks. The jacks can be in the form of telescopic lifting rams.
Electric tramway with unilateral guide - has pairs of tyred wheels on each bogie and separated by flange which runs in guide channel
