Section 1 (1st & 2nd Ed) - Excavators and attachments
Excavators - General |
Attachments 1. There are seven standard types of attachments which can be fitted to the basic machine: - a. Face Shovel - i. Crowd Shovel ii. Luffing Shovel. b. Skimmer Scoop. c. Drag Shovel (or Back Actor). d. Dragline. e. Grab and Clamshell. f. Crane g. Pile Driver. Face Shovel -
a. This attachment is illustrated in 'Ruston-Bucyrus 7/8 cu yd Excavator Type 24RB and attachments'. b. On this machine the jib is fixed during operation and the bucket is carried on an arm known as a "dipper". The dipper arm which is pivoted approximately half-way down the jib can be racked in or out or swivelled about the pivot. Racking the dipper arm out is known as "crowding" and increases the length of arm between the bucket and the pivot, causing the bucket to dig into the material being excavated c. The Crowd Shovel is used for the excavation of high faces such as those encountered in quarries. The upper half of the face should be removed first to prevent undercutting and to avoid having to force a full bucket through the whole height of the face. d. It is the most powerful of the attachments and can dig very hard material but rock faces require blasting first. e. Largely because of the fixed jib this attachment is the fastest in operation and consequently has an output factor higher than that of the Luffing Shovel describe below. 7. Luffing shovel.
Skimmer Scoop 8. The attachment is illustrated in 'Smith 5/8 cu yd Excavator Type 5/20 and attachments' 9. The Skimmer Scoop digs from the level of the tracks up to a height of about five feet. In operation the bucket runs on rollers along a movable jib. In addition to the jib attachment an auxiliary 'A' frame is incorporated as shown in the illustration in Smith 5/8 cu yd Excavator Type 5/20 and attachments 10. As its name suggests the Skimmer Scoop is used mainly for stripping off the layers subsoil for road formations. It leaves a very clean surface which needs little or no further. preparation before taking road bases. 11. Other uses are in road widening where restricted space prevents the use of Scrapers and for loading loose material into transport. 12. When using a Skimmer Scoop the following points should be noted a. The bucket must not be dropped heavily to the ground. b. Bumping the bucket against the stops at either end of the jib must be avoided. c. "Sweeping" to obtain a flat surface (i.e. resting the bucket on the ground and slewing the machine) must not be practised as it places undue stress on the centre post. d. The bucket must never be used for tamping. Drag Shovel (or Back Actor) 13. This attachment, which also incorporates an auxiliary 'A' frame, is illustrated in Smith 5/8 cu yd Excavator Type 5/20 and attachments. 14. . The bucket arm is pivoted at the head of' the jib and both the jib and bucket are moved together. The bucket moves towards the jib when digging. 15. The Drag Shovel is always used for digging below ground level and its primary use is for digging trenches for pipe lines and cables. It can however, be used for excavating foundations, etc. 16. When used for trenching, the machine straddles the trench and as excavation proceeds travels backwards leaving a clean -sided trench. 17. The Drag Shovel can perform three operations: - a. Excavation of the trench. b. Pipe-laying with the Drag Shovel alongside the trench lowering heavy pipes. c. Backfilling the trench with the Drag Shovel on one side of the trench and the spoil on the other side being pulled into the cavity. Dragline 18. This attachment is shown in Smith 5/8 cu yd Excavator Type 5/20 and attachments. The Dragline has a boom of lattice construction approximately twice as long as the jibs in the previous attachments. There is no bucket arm, the bucket being operated by ropes only. 19. The Dragline is normally used for digging below its own level especially at depths below those worked at the Drag Shovel. It has a far greater working radius than the previous attachments. The Dragline can thus be used for river dredging and digging deep cuttings. 20. The machine must work on firm ground and care must be taken that it is not too near the excavation, otherwise its weight may result in a crumpling of the edge and tipping of the machine. 21. In operation the hoist rope must not be let out so far that the pulley block lies in the bucket. The hoist rope must be let out sufficiently to place the bucket where required and during dragging the hoist chain must be sufficiently taut to keep the bucket digging into the excavation 22. The dumping rope may be adjusted in length to suit sticky or loose material. Figure I (a) shows the bucket when carrying sticky material, and Figure 1 (b) shows the angle of the bucket with loose or very wet material.
23. In hard material, or when the teeth have difficulty in penetrating the material, the drag clevis should be reversed as shown in Figure 2 (b). Sometimes this type of drag clevis is replaced by an ordinary lug which can be bolted in either of two positions about six inches apart vertically on the bucket.
24. The boom must not be derricked unless the bucket is on the ground to prevent wear the derricking gear. 25. The Smith 3/8 cu yd Excavator Type 2/10 with Dragline attachment may be modified for use as a "Side Dragline". The Side Drigline is especially suitable for excavating ditches and for excavating narrow cuttings where an ordinary Dragline cannot be used. 26. The Side Dragline stands close to the edge of the cutting to be excavated with its tracks parallel to the cutting, and travels backwards as excavation proceeds. The modification from the Standard Dragline to the Side Dragline is effected by shortening the bucket hoist chain on the side of the bucket furthest from the Excavator, and by shortening the drag chain on the bucket nearest the Excavator. Grab and Clamshell 27. An illustration of this attachment appears in Smith 5/8 cu yd Excavator Type 5/20 and attachments. 28. Both these attachments incorporate the Dragline boom and are used for handling loose in piles, and loading into transport. They can also be used for digging sand and silt beds. 29. Both attachments are operated by two ropes, a hoist rope and a holding rope The Grab, which has teeth, is used for harder and more uneven materials than the Clamshell, which has no teeth and which is used for handling sand etc. 30. In operation, the foot brake should not bind the hoisting rope drum otherwise the bucket may tend to close as it descends by the holding rope. 31. While the Grab (or Clamshell) is loaded the boom must not be raised or lowered as this causes wear on the derricking gear. Crane 32. This attachment is illustrated in Smith 5/8 cu yd Excavator Type 5/20 and attachments. 33. Onlv one drum is required for the operation of the Crane and the Dragline boom is used. 34. Care must be taken to lift loads gently and without jerks. The hoist clutch must be applied gradually until the full load is taken up. 35. It is important to ensure that the boom is set at the correct angle for the load to be lifted, in accordance with the load indicator on the boom. 36. The load must be lifted vertically and in slewing the load must be steadied to avoid swinging. 37. Like the Dragline and Grab, the Crane must not be derricked when carrying a load. Pile Driver 38. This attachment is similar to the Crane but instead of the hook the rope carried a large weight or "monkey" which is raised and allowed to fall on steel or timber piles which have to be driven into the ground. A system of guides is fitted to the boom so that the monkey hits the pile squarely and so that the pile is driven vertically. Notes on General Operation of Excavators 39. The excavator must stand on level ground otherwise slewing will be uneven and undue stress on the centre post will occur. If the machine is not level the surface of the lubricating oil in the engine sump may fall below the oil pump. 40. If the Excavator has to stand on boggy ground the machine must be placed on timber mats to distribute the weight and so prevent sinking. 41. To obtain maximum output and serviceability from the Excavator, smoothness in operation is as important as speed. 42. The position of the Excavator in relation to the transport and the job in hand together with the cycle of operations, must be considered before starting work. If possible place the vehicles to be loaded one on each side of the Excavator so that a quarter swing in one direction will load the first vehicle and while it is drawing away and another vehicle taking its place, a quarter swing to the other side will find another vehicle to be loaded. 43. An operator must never dismount from the machine leaving the bucket held by the brak off the ground. Normal operation tends to warm and so expand the brake housings-* the machine is left, the housings may cool off and contract allowing the brake to slip and th bucket to droçi. The bucket must therefore always be lowered to the ground before ieavjfl the machine. 44. The following points with regard to ropes should be noted a. Avoid sudden tautening and whipping. b. Avoid crossing or heaping up on the drums c. Avoid kinks when uncoiling new ropes. Changing Attachments 45. The maker's handbook (Volume I) should be studied before an attachment is changed and the rope reeving should be performed as laid down by the maker. Transporting Excavators 48. Wooden ramps, or metal ramps covered with wood, should be used in loading an Excavator on to a transporter. The Excavator tracks are smooth and they will slip on metal ramps. 49. Slewing must be avoided whilst on the ramps owing to the danger of collapse of the ramps under the stress. 50. If the Excavator is to travel without an attachment, it must be loaded up the ramps with the superstructure across the tracks otherwise the unbalanced weight may cause it to tip over. 51. After the Excavator is on the vehicle, it must be firmly chocked and chained to the body and the slewing lock must be engaged. |
Ruston-Bucyrus 7/8 cu yd Excavator Type 24RB and attachments |
|
|
|
Description | The excavator is fitted with a face shovel attachment of
the chain crows type. It is powered by a 77 hp diesel engine and
is suitable for working at quarry faces The engine and operating
machinery is placed to the rear of the centre post in order to balance
the weight of the jib, thereby reducing the stress on the centre post. When used as a Dragline, this excavator can have one of three different lengths of boom. The standard boom is 40 ft long, being made up of two sections but the addition of one of two different centre sections can be extended to 50 ft and 60 ft. (se diagram below) When the two longer booms are used it is advisable to fit a taller 'A' frame or to use a smaller bucket in order to reduce the stresses in the derrick rope. For the same reason, if it is necessary to work the Dragline with the boom at an angle of less than 40o, it is advisable to use a smaller bucket. This vehicle was shown in AP3036 (1st Edition) so was probably in use before 1944. It remained in the initial issue of AP3036 (2nd Edition) so was still in use |
