Description

FIELD

This relates to a fuel storage apparatus for forestry machines.

BACKGROUND

Fuel storage apparatus, in the form of storage tanks, are used in a variety of industries for the transport and storage of fuel, such as diesel.
In the forestry industry, for example, fuel storage equipment is essential in order to transport and store the fuel used to power forestry machines and other equipment used in the forest, with many forestry machines requiring significant volumes of fuel to operate.
However, the transport and handling of fuel for use by forestry machines poses a number of significant technical challenges.
For example, forestry machines typically operate in remote and often inaccessible locations, such that the handling of the fuel storage equipment is extremely difficult. The fuel storage equipment is also subject to the harsh environmental and operational conditions experienced in the forestry environment.
Moreover, equipment used within the forestry environment must also meet strict national and International standards, such that conventional fuel storage equipment designed is unsuitable for use within the forestry industry.
US 6,352,167 B1 describes a combination of a tool box with a fuel tank, comprising a tool box structure and a fuel tank structure. The fuel tank can be separated from the combination for independent use.
US 5,335,954 A describes a propane bottle carrier formed from a base, a handle, and a top ring. The base supports the bottom of the propane bottle. The ring is pivotally secured to the handle and is pivotable between an upwardly extending loading position in which the propane bottle can be inserted into the base and a holding position in which the top ring encircles the propane bottle.
US 6,138,853 A describes a portable container for fuel which has a sealable opening sufficiently large to permit access to the interior for a swab or cleaning device to wipe or vacuum the interior of the container.
US 2006/179602 A1 describes a hand-guided portable vacuum/blower device.

Beneficially, the cylindrical shape of the grab bar 16 facilitates handling of the apparatus 10 by a forestry machine or other handling equipment. The configuration of the grab bar 16 is particularly beneficial as it facilitates the handling of the apparatus 10 by a timber lifting grapple, commonly known in the forestry industry as a grab.
The apparatus 10 further comprises a sleeve 36 configured for location on and around the grab bar 16. The sleeve 36 is tubular in shape and in the illustrated apparatus 10 the sleeve 36 is constructed from a plastic material.
Beneficially, the sleeve 36 protects the grab bar 16 from damage and assists in the handling of the apparatus 10 by the forestry machine or other handling equipment. The sleeve 36 is particularly beneficial when the apparatus 10 is being handled by a timber harvesting machine having sharp de-limbing knives for taking the branches off the trees, since the sleeve 36 prevents or reducing blunting of the knives.
The apparatus 10 further comprises a support arrangement, generally denoted 38, for supporting the grab bar 16 and which couples the grab bar 16 to the lid 24. In the illustrated apparatus 10, the support arrangement 38 takes the form of a support frame and is constructed from steel. The support frame has side corner gusset plates having pear shaped holes which facilitate lifting of the apparatus 10 using a chain sling with hooks, or the like.

The fuel storage tank 14 further comprises a recess portion 44, the recess portion 44 shaped and sized to define a cavity between the fuel storage tank 14 and the outer housing 12 when the fuel storage tank 14 is housed in the outer housing 12. The recess portion 44 is configured to receive a monitoring device 46 which in the illustrated apparatus 10 takes the form of a warning float or the like, for monitoring for the presence of fuel between the fuel storage tank 14 and the outer housing 12. Beneficially, this permits leak monitoring to be carried out without the need to remove the fuel storage tank 14.
As shown in Figure 2 and referring now also to Figures 8 and 9 of the accompanying drawings, the fuel storage tank 14 further comprises a flange portion 48.
The fuel storage tank 14 further comprises a port 50 (shown in Figure 9) for facilitating access into and/or from the fuel storage tank 14.
As shown in Figures 9 and 10, the apparatus 10 comprises a manifold arrangement, generally denoted 52. In use, the manifold arrangement 52 controls access to and/or from the interior of the fuel storage tank 14. The manifold arrangement 52 comprises a manifold plate 54 for coupling the manifold arrangement 52 to the flange portion 48 of the fuel storage tank 14 via bolts 56 or other suitable fasteners. In the illustrated apparatus 10, the manifold plate 54 is constructed from metal, in particular steel.
Beneficially, the manifold arrangement 52 is configured to meet the requirements of national and International standards which govern the transportation and/or storage of fuel for use on the highway and/or in the forestry environment, e.g. UN ADR standards, while at the same time providing a fuel storage apparatus 10 which can be readily handled by forestry machines, and which is sufficiently robust for use in the forestry environment. Moreover, the manifold plate 54 may be removably couplable to the fuel storage tank, in particular the flange portion 48. Beneficially, this facilitates re-use of the manifold arrangement 52 while permitting the fuel storage tank 14 to be replaced, for example for periodic inspection or replacement or due to damage. In addition, the construction of the fuel storage tank 14 is simplified, since fittings do not need to formed in the fuel storage tank 14. In the event of damage to any of the fitting components of the manifold arrangement 52, the manifold arrangement 52 may be replaced without the requirement to also replace or remove the fuel storage tank 14.
With particular reference to Figure 10 of the accompanying drawings, which shows an exploded view of the manifold arrangement 52, it can be seen that in the illustrated apparatus 10 the manifold arrangement 52 comprises a plurality of fitting components, generally denoted 53. In the illustrated apparatus 10, the manifold arrangement 52 comprises a first fitting component 58, a second fitting component 60, a third fitting component 62, a fourth fitting component 64, a fifth fitting component in the form of a hose 66, a sixth fitting component 68, a seventh fitting component 70, an eighth fitting component 72, adaptor ninth fitting component 74, a tenth fitting component 76, an eleventh fitting component 78, a twelfth fitting component 80 and a thirteenth fitting component 82. As shown in Figure 10, the manifold arrangement 52 further comprises manifold washer profiles 84, and hose fittings 86.
Referring again in particular to Figures 1 and 2 of the accompanying drawings, it can be seen that the apparatus 10 further comprises a manifold cover 88 which is pivotably coupled to the lid 24. The manifold cover 88 is locatable over the manifold arrangement 52 and defines a curved outer surface.
Beneficially, the curved outer surface of the manifold cover 88 is configured so that, when the apparatus 10 is lifted by a forestry machine such as a grab, contact between the forestry machine and the manifold arrangement 52 which may otherwise result in damage to the manifold arrangement 52, the lid 24 and/or the forestry machine, instead results in the forestry machine sliding off the manifold cover 88.
Referring now also to Figures 11 and 12 of the accompanying drawings, it can be seen that the apparatus 10 may further comprise a removable tool cupboard 90, the tool cupboard 90 being secured to the outer housing 12 by a fastener arrangement, generally denoted 92 and comprising a plurality of fasteners 94 in the form of bolts.
