3 Terms and definitions
For the purposes of this document, the terms and definitions given in ISO 6165. ISO 6746-1, ISO 6746-2 and the following apply.
backhoe loader
self-propelled crawler or wheeled machine having a main frame designed to carry both front-mounted equipment (33) and rear-mounted backhoe equipment (normally with outriggers or stabilizers)
Note ito entry: When used in the backhoc mode, the machine is stationary and normally digs below ground level. Note 2 tu entry: When used in the loader mode (bucket use), the machine loads through forward motion.
Note 3 to entry: A backhoc work cycle normally comprises excavating, elevating. swinging, and discharging of material. A loader work cycle normally comprises filling, elevating, transporting and discharging of material,
base machine
machine with a cab or canopy and operator protective structures If required, without equipment (13) or attachments (3k) but possessing the necessary mountings for such equipment and attachments
set of components (3.6) mounted onto the base machine (3.2). which allows an attachment (3.5) to perform the primary design function of the machine
optional equipment
optional items olequipment (13) mounted onto the base machine (3.2) to increase, for example, capacity, flexibility, and comfort
assembly of components (3.6) that can be mounted onto the base machine (3.2) or equipment (3.3) for specific use
part or an assembly of parts of a base machine (3.2), equipment (3.3), or an attachment (3.5)
3.7 Masses
operating mass
mass of the base machine (3.2), with equipment (3.3) and empty attachtnent (3.5) in the most usual configuration as specified by the manufacturer, and with the operator (75 kg). full fuel tank, and all Fluid systems (I.e. hydraulic oil, transmission oil, engine oil, engine coolant) at the levels specified by the manufacturer and, when applicable, with sprinkler water tank(s) half full
ISOURCE: ISO 6016:2008, 3.2.11
Note ito entry: Ballast mass at delivery can be included it specified by the manufacturer.
shipping mass
niss of the base machine (3.2) without an operator, with the fuel level at 10 % of tank capacity or with the minimum fuel level needed for machine shipping purposes as specified by the manufacturer, whichever is higher, with all fluid systems at the levels specified by the manufacturer and with empty sprinkler tank(s), when applicable, and with or without equipment (3.3), ballast, attachment (3.5), cab, canopy, operator.protectlve structures, wheels and counterweights as stated by the manufacturer
