Description
FOR LIFTING A VEHICLE The invention relates to a lifting column, more specifically a mobile vehicle lifting column. Lifting columns are used for lifting passenger cars, trucks, busses, or other vehicles. The lifting column is often incorporated in a lifting system comprising one or more of these lifting columns. Conventional lifting columns comprise a frame with a carrier that is connected to a drive for moving the carrier upwards and downwards along a mast of the frame. In the ascent mode, hydraulic oil is pumped to a cylinder for lifting the carrier and, therefore, lifting the vehicle. In the descent mode, the carrier with the vehicle is lowered and hydraulic oil returns to the reservoir. For example, such prior art lifting column is disclosed in U.S. patent application publication No. 2006/0182563, which is incorporated herein by reference.
A problem with conventional lifting columns is that these columns restrict wheel access.
This can be problematic in case of wheel replacement, wheel hub motor maintenance, and brake drum maintenance, for example. These vehicle operations require several steps that need to be performed by an operator/mechanic. The steps include positioning of the lifting column relative to the vehicle, lifting the vehicle with a set of lifting columns. After lifting the vehicle an axle support is positioned, and the vehicle is lowered to engage the axle support. This allows for removal of the (mobile) lifting column. This provides access to the vehicle wheel. Mostly a so-called wheel dolly needs to be positioned to enable dismounting a wheel from the vehicle. The wheel can be lowered and removed from the vehicle using the wheel dolly. In case of a wheel change the new wheel will be provided to the vehicle using the wheel dolly that enables assembling the wheel to the vehicle. After mounting the wheel the wheel dolly is removed, the mobile lifting colamn is repositioned.
After removal of the axle support the vehicle can be lowered and the mobile lifting column carries the vehicle. This requires a lot of steps for the operator/mechanic to be performed and is therefore relatively time consuming. Furthermore, different types of equipment are required during the lifting operation that require movement. This constitutes a safety risk.
The present invention has for its object to obviate or at least reduce one or more of the above stated problems.
For this purpose the present invention provides a lifting column for lifting a vehicle, wherein the lifting column comprises: - a frame provided with a first mast and a second mast; - at least one carrier configured for engaging the vehicle, wherein the at least one carrier is moveable relative to the first and second mast;
- a lifting mechanism with a drive for moving the at least one carrier and lifting the vehicle, wherein the first and second mast are positioned on the frame at a mast distance, and wherein the mast distance enables access to the wheel.
In the context of the present invention the carrier relates to the moving parts of the lifting column that carry the vehicle when lifting this vehicle. This carrier is driven by a drive, such as a hydraulic drive, pneumatic drive and/or electric drive. The present invention relates to lifting columns, preferably mobile lifting columns, and more preferably to wireless mobile lifting columns.
The carrier of the lifting column is capable of carrying the vehicle that needs to be lifted. The carrier moves upwards and downwards relative to the frame and more specifically the mast(s) of the lifting column with the drive. The carrier comprises a carrying part that is configured for carrying of vehicle, or at least a part thereof. The carrier further comprises a guiding part that enables a guiding movement of the carrier relative to the frame and more specifically the mast(s) of the lifting column. In one of the presently preferred embodiments of the invention the drive is embodied as an integrated hydraulic cylinder as disclosed in U.S. patent application publication No. 2016/0052757. Preferably, the carrying part is one piece and moves relative to the first and second masts with the use of one or two guiding parts. It will be understood that other configurations for the carrier can also be envisaged according to the invention including a two- piece carrying part, for example.
According to the invention the frame is provided with a first mast and the second mast. These first and second masts typically extend in a substantially vertical direction enabling guidance of the carrier with the guiding part(s) thereof. The lifting mechanism with the aforementioned drive is configured for moving the at least one carrier along the first and second masts and thereby enabling lifting the vehicle.
Providing the first and second masts at a mast distance enables access to the wheel of the vehicle. The mast distance is defined by the distance between the mast sides that define the opening between the masts for wheel access. Preferably, the mast distance is in the range of 30-120 cm, more preferably 40-80 cm, and most preferably in the range of 40-70 cm.
The mast distance enables wheel access such that repair, maintenance and exchange of parts can be performed more easily. In addition, the safety risks associated with lifting a vehicle and performing maintenance are significantly reduced.
The lifting column according to the present invention enables a lifting operation with a reduced number of steps and provides a safer working environment. Steps include the positioning of the lifting column and lifting the vehicle. For removal of a vehicle wheel or wheel hub motor an axle support is positioned. Preferably, in case of a wheel change the wheel is dismounted from the vehicle after which the lifting column is lowered and the vehicle is supported by the axle support. The lifting column can be used to move the wheel and to provide a replacement wheel, for example. The lifting column is preferably used to lift the new parts, such as the new wheel, and position the wheel relative to the vehicle to enable mounting it to the vehicle. Thereafter, the axle support can be removed and the vehicle can be lowered. For example, this lifting column according to the present invention obviates the need for the use of a separate wheel dolly. This significantly reduces the number of steps that is required, thereby enabling a more effective repair and maintenance of vehicles. Furthermore, the working environment is rendered safer due to the limited number of required equipment and load shifts.
Vehicles are usually lifting with a number of lifting columns. Each of these lifting columns is designed to carry their respective load. Preferably, each of the masts of an individual lifting column is designed to carry this respective part of the vehicle load. This further increases safety when lifting vehicles with a number of lifting columns, especially in case of a failure in the drive of one of the masts. Optionally, an individual mast is designed to carry the respective load for the {5 invidual lifting column and not necessarily lift the vehicle in case of a failure or emergency. More specifically, an individual mast is designed to carry the so-called rated load of the lifting column.
In a presently preferred embodiment of the invention the first and second masts are symmetrically positioned on the frame. Positioning the masts symmetrically relative to the wheel access guarantees a safe support for the vehicle and/or vehicle parts. The substantially symmetrical design provides a safe load support reducing the risk of the lifting column bending or even collapsing with the risk of a vehicle falling from one of the carriers.
Preferably, the lifting column is designed such that the load acts on the carrier substantially in the center between the first and second masts. Such design contributes to stabilizing the load on the lifting column or lifting columns. Providing the load substantially in the center between the first and second mast enables a distribution of the forces acting on the lifting column in an effective and efficient manner over the first and second masts. This further contributes to a safe working environment.
In a preferred embodiment of the invention the lifting column further comprises a side- shift mechanism.
Providing the lifting column with the side—shift mechanism enables side-shifting the carrier, preferably the carrying part(s) thereof, thereby enabling (re)positioning of the carrier relative to the vehicle and vehicle parts without a required movement of the lifting column as a whole. This improves the alignment of especially the carrier and carrying part thereof relative to the vehicle. This enables an effective and efficient lifting operation. In a presently preferred embodiment to the carrying part comprises two fork parts that engage the vehicle wheel. The side-
shift mechanism preferably moves these fork parts in a direction that is substantially parallel to the vehicle length to enable alignment of the fork parts with the wheel, specifically the wheel axle.
In a further preferred embodiment of the invention the lifting column comprises a positioning mechanism.
The positioning mechanism enables movement of the carrier part such that the carrier is configured for engaging different wheel diameters. In case the carrier part comprises two fork parts the distance between the individual fork parts can be increased or decreased to enable handling of different wheel diameters. This improves the flexibility of the lifting column for lifting different vehicle types.
In a further preferred embodiment of the invention the lifting column further comprises a tilting mechanism.
The tilting mechanism enables tilting the carrier relative to the workshop floor. This improves safety when working with the lifting system. For example, after dismounting a vehicle wheel from the vehicle the tilting mechanism can be activated to tilt the carrier over a tilting angle to center and align the rim of the wheel with the wheel hab on the axle. This enables a correct connection and/or removal of vehicle parts and/or reduction of frictional forces when working on a vehicle. Also, this tilting mechanism improves safety of working on a vehicle. In addition, the tilting mechanism may have a stabilizing effect on vehicle parts that are carries with the carrier, such as a wheel. This improves the safety when working with the lifting column. The tilting angle is preferably in the range of 1-8°. The actual tilting angle may depend on the vehicle type. for example.
In a further preferred embodiment of the invention the carrier of the lifting column comprises a wheel rotational adjuster.
The wheel rotational adjuster enables rotation of the wheel during the lifting operation, also in a position wherein the vehicle is at a height above the workshop floor. Adjusting the rotational position of the wheel enables alignment of the studs on the hub with the bolt holes in the rim. This has advantages for the operator/mechanic that requires access to these vehicle parts. Preferably, the adjuster comprises rotational engagement means that can be manually driven or may involve the use of an adjustment drive, Optionally, the wheel rotational adjuster is a roller that is capable of carrying the vehicle or vehicle part, and acts as fork part. Such roller enables a vehicle wheel to rotate when the vehicle is being lifted. This provides additional flexibility for the operator and/or prevents that due to unexpected rotation of the wheel the stability of the lifting column can be influenced.
In a further preferred embodiment of the invention the lifting column comprises a locking mechanism configured for locking a wheel and/or components of a wheel assembly and/or other vehicle part(s) to the carrier and/or frame of the lifting column.
Providing a locking mechanism enables locking of a wheel and/or components of a wheel assembly and/or other vehicle part(s) after dismounting from the vehicle and/or when being provided to the vehicle that is lifted. This enables a safe lifting and/or lowering and/or movement of these parts. The locking mechanism may use a hook, pawl, catch, other suitable mechanical 5 locking means and/or other suitable means including magnets such as magnets including permanent magnets. It will be understood that other suitable locking mechanisms can also be envisaged according to the invention.
In a further preferred embodiment of the invention the lifting column comprises a controller that is configured for controlling movements and/or settings of the lifting column.
