A device designed for the removal, storage, and installation of removable hardtops from convertible sport utility vehicles, either from the rear or side, comprising a wheeled base unit, a vertical support structure and a top clamping assembly, wherein the base unit is aligned below the top frame and the vertical support structure connects them together, wherein the device can be disassembled for simple shipping, is adjustable for height and depth to accommodate different SUV models, and includes markers for easy assembly.

A device for controlling deformation of a large-scale crankshaft comprising a crankshaft holder that is arranged for fixing the crankshaft so that the crankshaft is aligned with an axis; a regulatory bracket that is arranged on the crankshaft holder at a position corresponding to the crankshaft; and a high-energy acoustic beam transducer that is arranged on the bracket and is provided with an end part coupled with the crankshaft. The crankshaft is fixed through the crankshaft holder, high-energy ultrasonic waves are injected into the crankshaft by the transducer, mass points in the crankshaft are driven to vibrate along the acoustic beam direction, and machining residual stress of the crankshaft is removed through the high-energy acoustic beam to realize the regulation and control of the residual stress in the material in the specific direction, so that machining precision of the crankshaft is ensured and machining deformation of the crankshaft is reduced.

In various embodiments, an engine mount may comprise a mount base configured to physically engage at least a portion of an engine positioned adjacent thereto so as to secure the engine in a mounted position relative to the engine mount, the mount base comprising: a base component; an engine positioning element protruding from the base component and configured to restrict a range of motion of the engine in at least one direction; and at least one base orifice extending through a thickness of the base component and configured to receive a protruding portion of the engine within an internal volume of the base orifice; and an attachment hub comprising one or more attachment features configured to receive at least a portion of an external engine tool and engage the external engine tool such that at least a portion of the external engine tool is arranged adjacent the mount base.

A wheeled engine stand and a process of using the engine stand is provided. The engine stand provides a wheeled base supporting a mounting head with retainers. The mounting head is reversibly attached to a drive shaft through a retaining pin extending through amounting head collar. A steering handle is detachably supported on an upper adaptor plate to allow for movement for the wheeled base.

The assembly stand comprises two parallel posts (1), a horizontal girder (6) which connects the tops of the posts and is vertically movable, and a suspension frame (17) which can be displaced along the movable girder in a lateral direction and is further suitable for turning the engine (M) mounted thereon about the main axes. A lifting block (10) is provided with a lifted load sensor to record the total weight of the engine (M). The device advantageously comprises a trajectory calculating control system integrating the structural deformations caused by the lifted weight, in order to correct the docking trajectories of the modules and ensure their utmost precision.

A versatile transport rack uses a rectangular shaped horizontal frame and one or more vertical frames that extend upwardly therefrom. Hinge pin receiver pairs are attached to the vertical frame and receive door pin pairs of a vehicle door. Either castors or axle-based wheel sets are removably attached to the horizontal frame in order to move the device about. Plates having appropriately placed templates are attached to the horizontal frame and/or the hinge pin receivers to hold various implements.
