Abstract

An apparatus enables a commercial vehicle tire hub drum to be attached and detached. The apparatus includes a main body frame having traveling wheels mounted on a lower part thereof and holding means that face forward from the main body frame for holding upright a circular load mounted on a commercial vehicle. An attachment/detachment means executes an attachment/detachment operation of the load from above the holding means. A position adjustment device coupled to the main body frame adjusts the position of the holding means and the attachment/detachment means. Accordingly, the apparatus uses a hydraulic device providing a hydraulic driving force to conveniently attach or detach a load of various sizes to a vehicle from a fixed position while simultaneously adjusting the vertical position of a load-holding means.

Claims17

Dependent claims

An apparatus for attaching or detaching a commercial vehicle tire hub drum, the apparatus comprising:

a main body frame;
a holding device formed so as to face forward from the main body frame for holding upright a circular load mounted on a commercial vehicle;
an attachment/detachment device for executing an attachment/detachment operation of the circular load from above the holding device;
and
a position adjustment device coupled to the main body frame to adjust positions of the holding device and the attachment/detachment device, the position adjustment device including a first position adjustment device and a second position adjustment device,
wherein the main body frame includes:
a main frame providing a moving space of the first position adjustment device for performing an elevating operation of the holding device;
and at least one sub-frame providing a moving space of the second position adjustment device for performing an elevating operation of the attachment/detachment device, and having a lower side to which the holding device bent in an ‘L’ shape is coupled,
wherein the main body frame further includes:
a connection frame connected and fixed to a predetermined portion of the holding device coupled to the sub-frame and predetermined portions of the position adjustment devices for performing the elevating operation of the sub-frame.

7 more elements

An apparatus for attaching or detaching a commercial vehicle tire hub drum to attach and detach a circular heavy object from a center of a tire wheel of a vehicle, the apparatus comprising:

a main frame formed on an upper rear surface thereof with an operation lever for controlling attachment/detachment operations, and provided on an outer side surface thereof with a hydraulic driving device for providing a hydraulic driving force under the control of the operation lever;
a sub-frame disposed in a vertical direction to enable elevating and lowering operations in front of the main frame while a holding device bent in an ‘L’ shape is fixedly coupled on a lower side;
an attachment/detachment device installed to move up and down at a center in the inner horizontal direction of the sub-frame to directly perform an attachment and detachment operations in close contact with a separated center of a tire wheel of the vehicle with respect to the circular heavy object;
and
a traveling unit mounted on a lower part of the main frame and including a moving device for enabling short-distance movement.
