Among the smaller capacity cars, the most popular and most widely used are the gravity dump types, such as rocker dump and scoop cars, designed so that the weight of the load tips the body when a locking latch is released by hand. The body of this type is balanced to right itself after the load is discharged. Rocker dump cars range in capacity from 1 yd₃(0.76 m₃) handloaded types, to units of 10 yd₃(7.6 m₃) for power shovel loading.
