Improvements or relating to earth moving machines BAMFORD EXCAVATORS 2 an mounted on the to one of boom adjacent the front of the hydraulic control valves for operation of the boom and earth working are mounted on the on the opposite side of the to the operators cab and adjacent the front of the and an engine compartment being arranged direetly behind the operators cab on the same side the boom as the operators cab and extending from the rear of the operators oab to the rear of the and the body of the earth moving machine being covered in a tective casing which has a generally flat surface over the majority of the bu which is of higher elevation over the engine thereby enabling the operator to a good view over the majority o the rear and sides of earth moving example of an earth moving machine now be described more detail b tray of with reference to the accompanying drawings 1 is a side elevation of an earth moving machine constructed i accordance with the 2 is a top plan view of earth moving machine shown 1 and is rear elevation of the earth moving machine in In this the earth moving indicated a 10 in the accompanying described as provided caterpillar 11 should be appreciated that if desired the earth moving 10 may be provided with four or more caterpillar tracks 11 arc provided in a very known in the art and form no part of the present and hence will not be described herein in She caterpillar tracks 11 are upon a turntable 12 to the end 13 of which is connected the of the body 14 of the earth the turntable member 12 allowing the 15 and hence the body 14 to pivot about a vertical axis relative to the ground caterpillar tracks Shis turntable nember 12 also be constructed in any Banner in the art and again forms no part of the present and hence will not be described in any store She 15 of the earth moving is generally rectangular in plan view the longer sides 16b of the rectangle being parallel to the central longitudinal axis of the sieving machine 10 and defining part of the sides of the body 14 and the 17b shorter sides the rectangle define part of the front and rear ends of the body 14 of the earth moving machine She 15 is not exactly rectangular and has certain detailed variations from but to facilitate description it convenient to consider the frame 15 as being It necessary when operating such a moving machine that the operator have a in all directions and can see the ground at shortest possible distance earth machine 10 so when reversing or the earth 10 does not collide with any objec An earth moving machine of this has an engine and a large of hydraulic control or oil tank for hydraulic oil and a tank for fuel and it is necessary to arrange these components both to enable easy access to be gained to which require maintenance and also so that they do not obstruct the vision of the the tallest component is the engine and hence this is the component which obstructs the most and in the present moving machine the engine arranged directly behind the operators in overall shape is generally and is arranged with its longer length parallel to the longer sides of the She engine is provided with a protective cover 29 of generally inverted rectangular channel having a flat upper surface the sides 31 of which are of unequal deeper side 31 extending downwardly to the 13 and thus ituting the side wall of that part of the body 14 of the earth moving machine e other side wall 30 is shallower for a purpose hereinafter to be cover 29 extends from the rear 32 of the operators cab 27 to the 17b of 15 of earth moving machine side wall 31 of the 29 made so that it can be hinged to enable access to bo to the and if it may also bo so that the whole cover 29 completely removable to facilitate major overall the oover 29 is also provided with ventilation louvres and the roar end of the oover is provided with a grill 35 behind which a radiator is On the other side of the boom to the operators cab between boom outer side 16a of the 15 are situated the various hydraulic control valves and these extend from the front end of the earth moving machine rearwardly for about two thirds of the length of the longer side of the frame She oontrol valves are also provided with a protective cove 34 which has a generally upper 55 is in plan view extends in its longer direction from above front end the 15 for about two thirds of the length of the longer side 16a of the and in narrower direction from above the side of tho frame 15 to closely adjacent the boom She horizontal part of the cover on the side which is above the 15 is provided with a side wall 3β which extends downwardly to the She hydraulic control valves are overall height than the and hence the also of loss overall than the oover 29 of the engine the aide provided w to enable it to be hinged upwardly to enable easy to be gained to the hydraulic control valves to facilitate behind the hydraulic control valveo there provided the hydraulic oil tank which extends to the rear end 17b of the 15 and is also provided with a cover 57 which of the and construction aa the cover provided for the hydraulic control in that it has a generally flat horizontal top 38 a downwardly side 39 which extends to the side of the 15 and a downwardly extending back wall 40 which to the end 17b of the behind the boom 19 and extending from the rear end 17b of the for about a quarter of the of the there is provided a tank for fuel for the engine of the earth moving machine and again the fuel tank also the apaoe front of the fuel tank between it and a position closely adjacent the ia also covered in by of the covor whioh has a flat upper surface and a back wall 43 extends downwardly to the end 17b of the the body 14 of the earth moving 10 a generally flat upper of the flat upper surfaces 38 and 42 of the en ine cover 2 h draulic n va v One of the the parts and extending length of i the of the boom 19 to the operators cab and other limb of tho comprising the parts 38 extending transversely across the rear of the earth machine one side thereof to the engine easing Directly behind the oab lies the hereinbefore described engine casing 29 which is of height relative to the remainder of the 14 of tho earth moving machine She hereinbefore mentioned other limb comprises the parts 30 and 42 of the upper surface of the body 14 extends to the bottom end of the hereinbefore mentioned shallower wall 30 of the engine casing tho highest part of the body 14 extends only directly behind the operators cab and hence the operator has a good with no interruption to the front and to one side of the earth and with minimum interruption to the side thereof opposite to that in which the cab is situated over the top of the cover and diagonally the earth moving machine in the general direction the hydraulic oil tank over the top of the covers 40 and o only region where his view is obstructed to any extent behind tho cab over the top 29a of the cover end the amount of obstruction since it is only a small part of the whole of his field of is not It will be appreciated that if the engine were placed transversely across the rear of the earth moving machine then the the rearward direction would over a much wider are with the present It will he appreciated that access can very he gained to which require maintenance engine and hydraulic control valves since the eidea 31 and 36 of the respective covers and are hinged and are easily accessible from the side of the insufficientOCRQuality
