Description

Towable carrier The present invention relates to a towable carrier for machinery, such as excavating arms, cement mixers etc. Other suitable machinery includes. Other suitable machinery includes, a fork lifting attachment, ripper attachment, post puncher, auger and chipper.
Excavators are well known devices that utilise a tracked or wheeled chassis and can rotate 360°. However, to move these excavators and other mobile plant from one site to the next it is necessary to use an on highway low loader truck or be carried using an on highway towable trailer etc. Also the three-point linkage which when fixed to the rear of a tractor is used to mount implements initially ploughs and then excavating arms, however this does mean the tractor is unable to carry out other tasks whilst using the implement.
The three point linkage is a standard arrangement for attaching implements such as ploughs to tractors. The three point linkage comprises three movable arms. All three arms are movable, with the two outer arms being powered and controlled by the tractor's hydraulic system.
Many implements are provided with a three-point linkage which allows them to be attached to the rear of a tractor. For example, an excavator arm can be attached to the rear of a tractor via the three point 1nkage, thereby converting the tractor into a digger. The three point linkage enables the implement to be powered from the tractor engine. A range of different machinery can thus be mounted on the rear of a tractor via the three point linkage. However, this has the disadvantage that whilst the machinery, such as an excavator, is being used, the tractor cannot be used for other tasks.
The present invention seeks to overcome these problems by using a self-trailering chassis, where a tow bar can be extended or lowered and at least two of the wheels are fitted with suspension, towable axles and lights resulting in a truly self trailing vehicle complying with road regulations.
The present invention provides a towable carrier for carrying an implement provided with a three point linkage, the carrier comprising: a chassis, provided with wheels; a three point linkage connection; a power pack to provide power to the implement.
The power pack may provide power to the implement through the three point linkage connection. The inclusion of a power pack ensures that the towable carrier and implement are self sufficient, without requiring the need for external power sources. The towable carrier is therefore adaptable for use with a wide range of implements requiring power. In addition, the inclusion of a power pack ensures the towable carrier has a source of power for any powered components, such as support legs etc) . The power pack may comprise any suitable device for providThg power to an implement, for example, an engine or a battery.
The towable carrier may further comprise a towing hLtch. The towing hitch may comprise a tow bar which is adjustable between an extended towing position and an unextended position. The towing hitch may be extendable or pivotable. The towing hitch may be lockable in either the extended towing position or the unextended position.
The chassis may be provided with two or more wheels, for example four wheels.
The towable carrier may further comprise a rear stabilizer which is adjustable between a lowered anchor position and a raised towing position. A hydraulic device may be used to adjust the rear stabilizer between its lower anchor position and its raised towing position. A power pack may provide power to the hydraulic device.
The chassis may be provided with suspension. Each suspension unit may be individually powered with hydraulic motors. The power pack may provide power to the hydraulic motors. The chassis may be provided with axles and some or all of the axles may be provided with individual pivotable devices to allow steering.
The towable carrier may comprise two support legs. The two support legs may be adjustable between raised and lowered positions. The support legs may be hydraulically powered. The power pack may provide power to the support legs. The support legs are individually adjustable to enable the towable carrier to be stable on an inclined surface. . When lowered, the support legs may extend in a direction transverse to the axis of the wheels.
By mounting the three-point linkage on the chassis the invention can be fitted with numerous upper platforms including an excavating arm and with its own power pack enables the excavator or other implement to be independent.
The chassis is also fitted with a rear stabilizer which can he used in a number of ways including being an anchor when excavating when lifted the stabilizer makes way for the two bar to extend.
Aspects of the invention include: * A three point linkage towable carrier that can be fitted with numerous upper platforms including an excavating arm and has its own power pack that enables the excavator or other implement to work independently.
* A three point linkage towable carrier wherein a three point linkage towable carrier tat is self trailering maintained, wherein the two bar is extendable or pivotable and mechanically locked in its normal day to day position and also similarly locked in its extended towing position. The suspension axles complete the ability to tow with road regulations.
* A three point linkage towable carrier wherein it is fitted with a rear stabilizer which can be used in a number of ways including being an anchor when using an excavator attachment or as a method of lifting into towing position.
* A three point towable carrier wherein the suspension axles are individually powered with hydraulic motors resulting in a one or more wheel driven carrier.
* A three point linkage towable carrier wherein some or all of the axles are provided with individual pivotable devices to allow steering.
Throughout the description and claims of this specification, the words "comprise" and "contain" and variations of the words, for example "comprising" and "comprises", mean "including but not limited to", and do not exclude other moieties, additives, components, integers or steps.
Throughout the description and claims of this specification, the singular encompasses the plural unless the context otherwise requires. In particular, where the indefinite article is used, the specification is to be understood as contemplating plurality as well as singularity, unless the context requires otherwise.
Other features of the present invention will become apparent from the following example. Generally speaking the invention extends to any novel one, or any novel combination, of the features disclosed in this specification (including any accompanying claims and drawings) . Thus features, integers and characteristics described in conjunction with a particular aspect, embodiment or example of the invention are to be understood to be applicable to any other aspect, embodiment or example described herein unless incompatible therewith.
Moreover unless stated otherwise, any feature disclosed herein may be replaced by an alternative feature serving the same or a similar purpose.
A specific embodiment of the invention will now be described by way of example with reference to the accompanying drawings in which: Figure 1 is a side view of an excavating arm; Figure 2 is a side view of the towable carrier of the invention; Figure 3 shows the excavating arm mounted on the towable carrier in the towing mode; and Figure 4 shows the excavating arm mounted on the towable carrier in the working mode.
Figures 1 and 2 show the chassis 1 utilising the three point linkage 2 which attaches to the implement (excavating arm) 3, when being towed the rear stabilizer 4 lifts and the two bar 5 extends the suspension axles 6 configures the chassis and its implement to a self trailering unit.
When the excavating arm 3 is attached to the chassis 1 via the three point linkage 2, movement of the arm is controlled via the three point linkage. Power to the three point linkage is supplied via the power pack (e.g. an engine), thus enabling the excavating arm and towable carrier to act as an independent unit.
The towable carrier has two modes of operation, a towing mode and a working mode. In the towing mode, the support legs of the excavating arm and the rear stabilizer are raised (both powered by hydraulics) and the tow bar is extended. In the working mode, the tow bar is retracted and both the support legs and rear stabilizer are lowered until the towable carrier is fully supported by the support legs and rear stabilizer.
By having an extendable tow bar, the tow bar may be retracted out of the way of the rear stabilizer in working mode. In its extended position it not only gives enough clearance for towing but acts as a safeguard against the rear stabilizer dropping during towing.
The towable carrier is provided with all the features required for it to be suitable for use on highways, such as wheels, suspension, mud guards, lights and registration plate.
The use of wheels (rather than a tracked chassis) makes the towable carrier particularly suitable for use in gardens or cemeteries as the wheels do not cut up the turf.
The towable carrier is also particularly suitable for use on uneven ground. A conventional digger on tracks must first dig itself a level platform from which to dig trenches. However, by contrast the towable carrier of the present invention is supported by the support legs and rear stabilizer which are hydraulically powered and allow it to self level, even when on uneven ground.
Figures 3 and 4 show the support legs positioned differently than shown in Figure 1. Rather than being transverse to the digging arm, the support legs are positioned almost parallel to it. This position has two advantages. Firstly, it brings the support legs away from the wheels and secondly, it positions the support legs either side of the excavation site, giving further stabilising during digging.
