(in Russian, dyba), an instrument of torture consisting of two posts rooted in the ground and connected by a third post on which the victim was hoisted [and whipped]. It was used in Europe and Russia from the 14th to the 18th centuries. Torture on the rack was stipulated in the Pskov Judicial Charter.
a single-axle tractor trailer for the mechanized loading, transport, and unloading of stacks of hay and straw with a total weight up to 6 tons, as well as sections of ricks cut by a rick cutter. Racks may also be used to haul other agricultural loads. When the trailer is used to transport stacks, the side panels are folded down, the front panel is removed, and a framework of bars to hold the stacks is mounted in place of the panels. Horizontal extensions are used to increase the load area of the bed. The rear bars of the framework are lowered to the ground for loading and unloading. Stacks are loaded onto the bed and unloaded by means of a loading grid. Prior to being transported, the stacks are bound with rope. Racks are used with tractors in the 3-ton-force class.
