Description
TITLE OF THE INVENTION Unit, attachable to a loader.
TECHNICAL FIELD
The present invention relates to an assembly capable of being attached to a loader and in particular to a loader which is originally equipped with attachment means intended for co-operation with a respective one end of two lifting arms whose other ends are intended to carry suitable load-handling devices, such as lifting forks, buckets etc., and where the lifting arms and load-handling devices are de-tached. In addition, the loader includes lifting ram attach-ments intended to co-operate with respective first ends of two lifting ram assemblies whose respective other ends co-act with the lifting arms, and where the lifting rams are detached.
The invention is thus based on the concept of enabling a conventional loader retailed for service in one particular working area, e.g. as a sand loader, to be adapted with the aid of simple means for effective work in a completely different field, e.g. as a timber-bundle loader, by remo-ving the bucket and associated lifting ram assemblies fromthe loader and substituting the same with an assembly which is adapted for loading work in the new field.
The invention also relates to one such assembly which is provided in the central region thereof with means for connecting the same to attachment means originally provided on the loader, and the other part of which presents a pivot attachment for pivotal co-action with a load-handling arrangement, normally an operating arm or jib arrangement.
BACKGROUND ART
There is known from Swedish Patent Application No.7800001-5, published with serial number 409 694, a loader in the form of a two-part vehicle, whose forward part and associated wheels is journalled for rotation to the rear vehicle-part and its associated wheels. The rear vehicle part carries the .. ~
machine motor etc., whereas the forward part of the vehicle carries the load-handling equipmen-t of the machine, such as the loading or lifting assembly. According to the invention there is also connected to the forward part of the vehicle a main assembly which is mounted on a plurality of wheels which support against the ground or surface on which the vehicle stands and which are located forwardly of the axle of the front vehicle wheels, said main assembly carrying part of the load-handling equipment.
The main assembly illustrated here presumes that a unit provided with load-supporting wheels is connected to the axle-attachment of the forward part of the machine, or adja-cent a part of said attachment, and to a further attachment means located over the axle-attachment placed on the forward part of the vehicle. The main assembly incorporates a hydrau-lic piston-cylinder device which is intended to power a lifting assembly and which extends between the axle-attach-ment of the assembly, or a part adjacent thereto, and a lifting arm forming part of the lifting assembly.
The pertinent prior art also includes the arrangement descri-bed and illustrated in Swedish Patent Application No.14151/77, published with serial number 356 489. Described and illustra-ted in this publication is a loader which supports a liftingassembly which is controlled from a control seat located in the forward part of the tractor and which includes a rais-able and lowerable lifting arm, the forward end of which carries a gripping assembly comprising gripping arms desig-ned, for example, to grip and lift a hundle of elongatedobjects, such as logs. The lifting arms can be extended telescopically and are journalled for vertical movement on a~ournal shaft which extends substantially parallel with the control seat of the machine and above the same.
The arrangement illustrated and described in Canadian Patent Specification No. 1,010,827 also forms part of the pertinent prior art.
1260~8~i' SUMMARY OF THE INVENTION
TECHNICAL PROBLEM
With reference to the existing state of the prior art, particularly as expressed in the aforesaid publication 409 694, it is obvious that a serious technical problem is one of providing with the aid of simple means an assemb-ly which can be attached to a loader with the aid of exis-ting attachment means and lifting-ram attachments for suitable loading devices, so as to enable said assembly to be readily attached to the loader.
It will be seen that a further qualified technical problem in this regard is one of providing conditions which will enable the assembly to be made liyht in weight and any form of load-supporting wheels to be omitted, while provi-ding nevertheless a stable and robust structure capable of withstanding and absorbing the extremely large forces to which the assembly and the loader are sub]ected when loading the load-handling equipment with weights of up to 30 tons.
Another technical problem is one of constructing, with the aforesaid conditions in mind, an assembly which can be readily fitted to the loader.
A further qualified technical problem is then one of enabling the assembly to be readily attached operatively to the loa-der, while still constructing the assembly for heavy loads.
Another technical problem is one of providing conditions which will enable an assembly capable of being fitted to a loader to be removed therefrom, and enable the assembly to be readily modified for an intended use within an initially intended field.
SOLUTION
The present invention thus relates to an assembly which can be fitted to a loader provided with attachment means for co-operatior. with a respective one end of two lifting arms whose respective other ends are intended to support suit-able loading devices, such as lifkiny forks, buc~ets etc., and with lifting ram attachment intended for co-oper~tion with a respective one end of two lifting rams whose other ends co-operate with the lifting arms, and where the assembly is provided in the central reyion thereof with means for co~operating with said attachment means and is further provided in the upper part thereof with pivotal attachment means for pivotal co-action with a part of a load-handling arrangement.
In accordance with the inve~tion, the lower part of -the assembly extends towards the standard front wheels of the loader and is firmly connected to the lifting ram attach-ment originally provided on the loader.
According to one embodiment, two elongated, fixed membersextend between the lowermost part of the assembly and the lifting ram attachments. These members are pivotally connec-ted at both ends thereof.
The invention also proposes that the lower part of theassembly incorporates a transverse beam having proyided adjacent thereto attachments for one end of one or more piston-cylinder devices, the other end, or ends, of which act on an operating arm or jib forming part of a load-handling arrangement. The arm conveniently has a telesco-pic function.
The attachment intended for the one end of the piston-cylinder device ac-ts at the center part of the arm. The arm is also preferably curved and the telescopic function thereof is placed in an upper arm portion.
In accordance with a further embodiment, the lower part of the assembly is located immediately above the front wheel axle.
12~987 s The assembly preferably comprises two side members which are joined together in the upper assembly part and in the lower assembly part.
_DVANTAGES
Those advantages primarily associated with an assembly according to the invention capable of being fitted to a loader reside in the provision of conditions which enable the assembly to be readily fitted to an existing loader simply by utilizing attachment means and lifting-ram attach-ments already found on the loader and without removing the wheels of said loader.
The main characterizing features of an assembly according to the present invention capable of being fitted to a loader are set forth in the characterizing clause of the following Claim 1.

The grippers 12 and 13 can be opened and closed by means not shown, and can be rotated or swung in a vertical plane, by means not shown.
It will be seen, however, that the lower part 15 of the e ~
.
assembly extends down to the front wheel 16 of the loader 1 and is, in particular, located above a centre wheel axle 17.
The lower part 15 of the assembly is also firmly connected to the lifting ram attachments 4. Extending between the lower assembly part 15 and the two ram attachments 4 are two elongated stationary members 18, which are pivotally connected at one end 18b thereof to a respective ram attach-ment 4 and at the other end 18b thereof are pivotally connec-ted to an attachment means 19 mounted on the lower assembly part 15.
The lower assembly part 15 incorporates a transverse beam 20 adjacent which there are arranged attachments for one end 22a of one or more piston-cylinde devices 22, there being two such devices in the illustrated embodiment, the other end, or ends, 22b of which act upon the operating arm 9 forming part of a load-handling arrangement.
The arm 9 incorporates a telescopic action, the nature of which will not be described here. The attachment means intended for the said other end 22b of the piston-cylinder device 22 acts at the centre part of the arm 9. The arm 9 i slightly curved and the telescopic action of the arm is restricted solely to the upper part 9a thereof, whereas the lower part 22a is arranged so as to be located immedia-tely above the centre axis 17 of the front wheels 16.
Figure 3 illustrates the part 10 in its extended state.
Axial movement of the part 10 is effected with the aid of a piston-cylinder device 25. When the part 10 is fully withdrawn from its extended state, the rear part 11a will be located adjacent the attachment means 8.
The assembly comprises mainly two side members 23,24 which are connected together at the bottom thereof through the beam 20 and at the top thereof through ~eupper part 7 of the assembly.
