Abstract: Vehicles are disclosed for the internal transport of heavy-load coils. The vehicle may include a drive unit and a loading device coupled thereto. The loading device may be configured to hold a plurality of heavy-load coils. An articulated steering system may be formed between the drive unit and the loading device. The vehicle may include separating elements connected to the loading device, which may be movable parallel to a vehicle longitudinal direction. The separating elements may be configured to secure heavy-load coils of different widths against tilting.

Abstract: A clamp-type locking mechanism includes a housing (1) with an inner cylindrical clamping surface (3) and with driving elements (5) and driven elements (4) positioned concentrically therewith. The driven element (4) is provided with clamping ramps (23, 24) facing the clamping surface (3), which have arranged thereon clamping roller pairs formed of two clamping rollers (25) successively placed along the circumference. Both clamping rollers (25) are spring-biased by an interposed spring element (26, 30) in direction away from each other towards the clamping surface (3) and the clamping ramp (23, 24), with the driven element (4) being provided with stops (28) for claws (19) of the driving element (5).
