Abstract
The bucket arm 1 of an excavator is provided with one or more toothed plates 4 which cooperate with the bucket 2 to retain materials or objects O, other than earth, by gripping. <IMAGE>
Description
SPECIFICATION
Improvements in excavators
A mechanical excavator may be used to transport excavated materials which will fit within its bucket, for example rock and concrete.
However, elongate objects such as tree trunks, telegraph poles and long ironwork cannot readily be handled. This problem has been solved by the simple expedient proposed herein of providing the arm to which the bucket is articulated with at least one formation for cooperation with an object or materials supported by the bucket.
The drawing shows one embodiment of the invention, purely by way of example.
Referring to the drawing, an excavator has an arm 1 to which a bucket 2 is articulated.
The bucket is movable by a hydraulic ram 3 in the usual way. Welded, or otherwise secured, to the sides la of the arm are two plates 4, the edges of which facing the bucket have teeth 5. Extension of the ram 3 so as to urge the bucket 2 towards the arm allows an elongate object 0 (or materials other than earth) to be clamped between the bucket and the plates 4. The teeth 5 are directed towards the axis of articulation of the bucket so as to prevent the object 0 slipping out when the arm is raised. The use of two plates 4 increases the stability with which the object is held.
Modifications may be made to the arrangement illustrated. Thus, for example, instead of fixing two profiled plates to the sides la of the arm 1, a single profiled bar may be fixed to the front surface ib of the arm. Although a series of tooth-like formations substantially as illustrated is preferred, a projection or a hooklike formation on each plate 4 (or a single hook on surface 1b) may be used instead.
The formation or formations may be integral with the arm. Conceivably, the plates may be mounted for movement parallel to the arm under the action of a further ram so as to provide a vice-like action. The expression 'bucket' as used herein is to be interpreted broadly to include any working implement which may be pivoted to the excavator arm and used to grip an object in cooperation with the formations.
1. An excavator including a bucket articulated to an arm, at least one formation being provided on the arm for cooperating with the bucket to retain an object or materials to be held.
2. A pair of plates provided with teeth along one edge, the plates being mounted or mountable on respective sides of the bucket arm of an excavator.
CLAIMS
Amendments to the claims have been filed, and have the following effect:
New claims have been filed as follows:
3. An excavator including a bucket articulated to an arm, the arm being provided with at least one row of teeth directed towards the axis of articulation of the bucket and rigid with the arm, whereby an object or materials to be held may be gripped between the bucket and the teeth.
4. An excavator substantially as described with reference to the drawing.
