3.3 Attachments
3.3.1
attachment
ascmbIy of components that can be mounted onto the base mac hlne (3.1.2) or equipment for specific use
LSOURCE: ISO 6746-2:2003. definition 3.5J
3.3.1.1
hackhoe
attachment (3.3.1) whIch generally excavates towards the machine and below ground level, and which elevates, swings and dumps material by the action ala boom, arm and bucket
Note ito entry: For dedicated back hoe loaders, see ISO 8812
3.3.1.2
scantier
attachment (3.3.1) having teeth for penetrating and loosening to shallow depths materials such as earth, asphalt and gravel for roads and for similar functions
See Figure 19
Note ito entry: It Is usually mounted on the back of the loader but can be mounted on the back of the bucket.
3.3.2
side dump bucket
bucket which loads through forward motion of the machine and which can dump to the side from an end, or dump forwards
See Figure 17
3,3.3
multi-purpose bucket
bucket having a dozer-type mouldboard with hinges at the top to support a clam which can be opened to various positions, providing for use as a dozer, scraper, clam or bucket
See Figure 17
3.3.4
fork arm
structure having tines for lifting, transporting and discharging warehouse-type pallets See Figure 22
Note ito entry: When the fork attachment is fitted to a loader, the machine is still classified as an earth-moving machine, not a rough terrain fork truck.
3.3.5
log fork
log grapple
mechanism having tines and a top clamp for lifting, transporting, and discharging logs See Figure 23
3.3.6
winch
frame equipped with a drum and connected to the rear part of the base machine (3.1.2) See Figure 24
3.4
equipment
set of components mounted onto the base of the machine to provide the primary design function of the loader
