It should be noted in the following description that like or the same reference numerals in different embodiments denote the same or similar features.
There are three distinct versions of the load carrier for vehicle detailed hereinafter which can be categorized as:
Referring to
It should be noted that the steps can be undertaken in reverse order and each step can proceed to the next step or recede to the previous step.
Version a)
Referring to
One embodiment of Version a) is the ground set-up hoist lifting version 31 shown in
In the form shown in
The telescopically extendable upright 33 has its structural integrity increased by slidable supporting braces 34 pivotally mounted to the ground engaging counterweight base 39 at one end and at the other end having a circular ring just circumventing the upright sufficient to provide support while allowing sliding motion from an operative expanded form with structural integrity and capabilities to lift a load onto a vehicle to a storage and reduced form.
A lift cable 35 extends over the supporting frame from the end of the overhanging arm 32 distal to the connection to the upright 33. Supporting the end of the overhanging arm 32 is a triangular arrangement including a pivoting crank arm 36 pivotally connected to the top of the upright 33 and extending upwards to an upper support point 37 and has a suspension cable 38 extending from the support point 37 to the lower end of the overhanging arm 32. This support point is retained in position by connection to the lift counterweight 39 comprising the ground engaging counterweight base 39A and a support line 39B extending from the ground engaging counterweight base 39A to the support point 37.
The lift cable 35 such as a rope and shackle pulley extending from the supported end of the overhanging arm 32 can suspend to the rectangular vehicle roof mounted supporting lift tray 21 from the distal end of the lift arm 32.
The lifting apparatus 31 is mounted on a lift counterweight 39 having a ground engaging counterweight base 39A formed from a plurality of spaced ground engaging feet radiating feet to provide stability which feet extend from the upright 33. The engaging counterweight base 39A can be mounted on wheels or castors so as to be movable from a spaced distance from the vehicle 15 to a position under the vehicle while the supporting lift upright 33 extends up alongside the vehicle and the lifting arm 32 overhangs the top of the vehicle 15.
Referring to
The ground set-up hoist lifting version 31 is then wheeled to the side of the vehicle and has its legs 39A extend under the vehicle so the overhanging arm 32 can extend over the vehicle 15. The load 10 on the lift tray 21 can then be lowered onto the top of the vehicle 15 by manipulating the cable and pulley of the lift cable 35.
Referring to
Another embodiment of Version a) is the ground set-up gantry system 41 shown in
As shown in
In particular the lifting apparatus 41 has an overhanging gantry arm 42 which extends between two sets of inverted V arranged telescopic legs 43 held apart by spacing means 44 at the base. A lift cable 45 is suspended from the overhanging arm 42 and has a rope and shackle pulley.
Referring to
Version b)
As shown in
One embodiment of Version b) is the two arm lifting version 51 as shown in
The lifting version 51 lift tray has the two arms 52 connected to a vehicle lift mount 50 which forms the base of a triangular arrangement with the two arms 52 and is connected to at least part of the top of the vehicle 15. The point of the triangular arrangement is connection 54 from which a lift cable 55 can extend. The lifting arms 52 supports a lift cable 55 connectable to the lift tray 21 for supporting the load 10. The two lifting arms 52 extends from pivot support 52A and 52B on one side of the lift tray 50 to beyond the other side of the vehicle.
Due to the telescopic nature of the inverted V lifting arms 52 there would not be a consistent angles at the vertex between the two telescopic legs if the two legs remained of similar length and an isosceles triangle existed. This would need an alterable connection at the vertex 54 of the telescopic legs 52. However another option as shown particularly in detail F of
The two arm lifting version 51 further includes two telescopic legs 56 forming a pivot brace which another but smaller inverted V shape is extending in opposite direction to the inverted V of the two overhanging telescopic lifting arms 52. These other two telescopic arms 56 are joined to the side support 50 similarly to the inverted V of the two overhanging telescopic lifting arms 52 to the side support 50.
The lifting arms 52 of the two arm lifting version 51 includes a support cable 58 extending from the lift tray to the vertex of the two overhanging telescopic lifting arms 52 at or near a top portion of the pivot connection 54 and down around the oppositely protruding vertex 57 of the inverted V shape of the pivot brace 56 and extending at an angle down alongside the side of the vehicle thereto but spaced from the vehicle 15 in use. A counter weight or base 59A can be ground engaging and extend under the vehicle connected to the support cable 59B. The support cable 59B can be used to retain the vertex 57 of the pivot brace 56 stable to provide support by the overhanging support cable 58 of the end 54 of the two overhanging telescopic lifting arms 52.
The lifting cable 55 further includes a lift pulley for aiding the user to lift the load 10 with the lifting apparatus 51 wherein the lift pulley extends to an upper part of the lift arm 52 of the lifting apparatus and includes a pulley arrangement to provide a mechanical aid.
As shown in
Another embodiment of Version b) is the single arm lifting version 61 shown in

Version c)
Referring to
One embodiment of Version c) is the scissor lifting version 71 shown in
The lifting legs 73 extend from side rails 74 that can be extended laterally from the lift tray 21 by lateral extensions 72. The lifting legs 73 being spaced from the body of the lift tray 21 by lateral extension 72 allow the lifting legs 73 to extend alongside the sides of the vehicle 15. The lift tray 21 can then be supported by the ground engaging lifting legs 73.
The lifting legs 73 can use a scissor lifting arrangement and can use a hydraulic lifting arrangement. However as shown in the Figures the lifting legs use a cross leg system with the lifting legs using a telescopic legs lifting arrangement. In particular the side rails 74 can capture the top 73A, 73B of the legs 73 with one being held in position while the other can slide. This will affect the angle of intersection of the scissor configuration legs 73 and result in alteration of the height of the lift tray 21.
In loaded position on the vehicle the lift tray 21 the side rails 74 can be laterally extended by lateral extension 72 from the lift tray 21 and then the legs 73 released downwards from the side rails 74. The lifting legs extend from leg extension support on opposite sides alongside the sides of the vehicle and engage the ground to self-support the lift tray 21 and the load 10 thereon and allow the vehicle 15 to move relative the load carrier.
The lifting legs 73 can then have a captured top 73A, 73B of the legs 73 slide within the side rails 74 to affect the angle of intersection of the scissor configuration legs 73 and result in lowering of the height of the lift tray 21 and load to a ground position as shown in
Therefore the system allows a single person to retract and lower the lift tray 21 and load 10 thereon to the lower position to receive a load in a consistent vertical orientation and allow the lifting legs to lift the load from the lower position in the consistent vertical orientation to the raised position at or above the vehicle roof and allow the vehicle to move relative the load carrier to allow the load to be lifted in the consistent vertical orientation and supported on the vehicle in the same consistent vertical orientation.
In the embodiment of the tensioned telescopic leg version 81 shown in
Each pair of legs 83 extend from opposite ends of the side rail 84 and splay outwards along the side of the vehicle. To limit the splay there is a set of cross over support cables 85 extending from a low point of a leg 83 to a high point on the other leg 83 on that side or to the nearby portion of the side rail 84. The pivoting legs are controlled in their splaying to affect the angle of splaying of the legs 83 and result in lowering or raising of the height of the lift tray 21 as shown in comparison between
