BEST MODE OF CARRYING OUT THE INVENTION :~
The crane 1 ls shown as erected ln Flgs. 1 and 2. The crane 1 ::
includes a mountlng base 2 whlch is rotatably mounted ~nto a recess on the tray of a motor vehicle ~not lllustrated) such as a pickup truck or WO 93/121)29 PCl'/AU92/00666 ~ Qj~
the like. The mounting base 2 lncludes a round plpe 3 and a circular flange 4. The roun~ p~pe 3 fits within the recess with the c~rcular flange 4 rest~ng on the tray of the motor veh~cle.
Protrud~ng perpendicularly to the p~pe 3 is a rectangular hollow section tube (RHS) of a base frame 5. The base frame 5 ~s welded to the pipe 3, and a bracing triangular plate 6 ls welded on the opposite side - to prov~de strength.
A RHS post 7 has a RHS perpend~cular connecting member 8 welded to its lower end 9. Another bracing triangular plate 11 is welded at the connection to provide strength. The RHS tube of the connecting member 8 ~s rece~ved with~n the RHS tube of the base frame 5 and a pin 12 ~s inserted ~nto holes 13 to secure the connect~ng member 8 and base frame 5 together.
The post 7 has at ~ts upper end 14 a p~r of connecting strlps 15.
The connecting strips 15 are pivotally connected to the upper end 17 of the post 7 by a pin 18 which is inserted into holes 19. A winch 20 is attached to a mount~ng bracket 21 which ls mounted on the post 7 via pins 22 wh~ch pass through correspond~ng holes 23 ~n the post 7. The mount~ng bracket 21 ~s pivotal about the top p~n 22.
A RHS l~ft~ng arm 25 ls pivotally connected to the post 7 by the connecting str~ps 15. The connecting str~ps 15 are welded to both sides of the lift~ng arm 25 adjacent one end of the l~ft~ng arm 25. As ~llustrated ~n the drawings, the l~ft~ng arm 25 comprises three sections which are telescopically recelved within each other. Pins 26 are used through holes 27 to provide the actual conf~guration for use and non-use. A wire rope 28 from the winch 20 passes up from the winch 20, through the ~nter~or of the telescoplc l~ft~ng arm 25, and has a hook 29 at its end.
Another pa~r of connectlng strips 31 are welded to the sides of the outside one of the sect~ons of the telescop~c llfting arm 25. A RHS
telescop~c brace 32 is connectable between the connect~ng strips 31 and another parr of connect~ng strlps 33 wh kh are welded on the top of the mounting base 2. The brace 32 ls p~votable through p~ns 34, 35 wh~ch pass through holes 36, 37 on the connectlng str~ps 31 and 33 respectlvely. A pln 38 pass1ng through holes 39 ~n the telescop~c brace 32 sets the length of the brace 32 for each partlcular conf~guratlon.
The crane 1 ls 111ustrated ln two use conf1gurat~ons ~n F~gs. 1 and 2. The connectlng member 8 ls recelved wlthln the base frame 5 and the post 7 is erected w~th the winch 20 located on the mounting bracket 21.
I~ ~he conf~guration as illustrated ~n Fig. 1, the lifting arm 25 is hc :ontal and telescoplcally extended. The brace 32 is set by the pins 3 The crane 1 ~s rotatable about the axis of the pipe 3 and therefore is able to turn to load or unload the tray of the motor vehicle on which the crane 1 is erected.
In the configuration as illustrated ~n Fig. 2, the l~fting arm 25 is shown at an angle of approximately 45 to the horizontal. The lift~ng arm 25 has been plvotted about the pins 18 which pass through the holes 19 in the connect~ng str~ps 15 and the post 7. For this operating configuration, the brace 32 is extended using the pins 38, with the two sections of the brace 32 are telescopically extended. The configuration as illustrated 1n Fig. 2 is to be used for larger 1tems and for d~fferent lifting procedures.
When the crane 1 is no longer required for use, it ~s folded to the folded-configuration as illustrated ~n Fig. 3. To accomplish this configuration, the telescop k lifting arm 25 is shortened to its shortest length as ~llustrated in Fi~. 4. The p~ns 26 are used to secure the arm 25 at this length.
The brace 32 is disconnected from the connecting strips 33 of the mount~ng base 2 by removing the pins 35. The telescop~c brace 32 is then shortened to its shortest length as ~llustrated ln Fig. 4, and pivotted .
around the pin 34 to lie bes~de the lifting arm 25. In th~s position, the end of the brace 32 is rece~ved between the pair of connecting strips 31 as illustrated in Fig. 4.
The liftlng arm 25 is then able to be pivotted downwardly to then -~
lie vertically alongslde the post 7. The` brace 32 ls positioned between the post 7 and lifting arm 25. A pin 41 is passed through a hole 42 at the lower end of the post 7 and through holes 43 located in the pair of connecting strips 31. The pin 41 ensures that the post 7, the brace 32 and the lifting arm 25 are secured together.
To c~mplete the foldlng process, the lower pin 22 on the mounting bracket 21 is removed and the mounting bracket 21 is pivotted upwardly into the position illustrated in F~g. 3. The winch 20 is in the position adjacent the end of the l~ftlng arm 25. The connecting member 8 is then removed from the base frame 5 by removing the pin 12. The crane 1 ls now able to be removed from the motor veh1cle and as the crane has a handle 45 located on the slde of the post 7 it ~s able to be carrled by hand.
