The work of preparing International Standards is normally carried out through IS0 technical committee
6、s. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, govern- mental and non-governmental, in liaison with ISO, also take part in the work. IS0 collaborates closely with the Int

11、ERNATIONAL STANDARD IS0 10567:1992(E) Earth-moving machinery - Hydraulic excavators - Lift capacity 1 Scope This International Standard provides a uniform method to calculate hydraulic excavator lift capacity and a test procedure for verifying the calculations. It covers both hydraulic lift capacity
12、 limits and ma- chine tipping limits and establishes the rated lift ca- pacity for hydraulic excavators as defined in IS0 7135. 2 Normative references The following standards contain provisions which, through reference in this text, constitute provisions of this International Standard. At the time o
13、f publi- cation, the editions indicated were valid. All stan- dards are subject to revision, and parties to agreements based on this International Standard are encouraged to investigate the possibility of ap- plying the most recent editions of the standards in- dicated below. Members of IEC and IS0
14、maintain registers of currently valid International Standards. IS0 6015:1989, Earth-moving machinery - Hydraulic excavators - Methods of measuring tool forces.

15、 this International Standard, the following definitions apply. 3.1 load: External force, including the weight of the attached equipment, applied at the lift point. 3.2 liff point: Location on the bucket or the bucket mounting bracket, specified by the manufacturer, to which a load may be attached, o
16、r the centre-line of the bucket pivot mounting pin on the arm. For bucket 1) To be published. or bucket mounting bracket load attachment, the bucket cylinder is fully extended. See figure 1. 3.3 lift point height: Vertical distance from the ground reference plane to the lift point. See figure 1 3.4
17、lift point radius: Horizontal distance from the axis of rotation to the vertical hoist line or tackle. See figure 1. 3.5 balance point: Moment acting to overturn the machine with a specific load and point lift radius which is equal to the moment of the machine avail- able to resist overturning. 3.6
18、tipping load: Static load at the balance point. 3.7 rated tipping load: 75 % of the static tipping load. 3.8 Hydraulic pressures 3.8.1 working circuit pressure: That nominal pressure applied to the specific circuit by the w-w(s) 3.8.2 holding circuit pressure: Maximum static pressure in a specific c
19、ircuit, limited by a relief valve at a flow no greater than 10 % of rated circuit flow. 3.9 hydraulic lift capacity: Load that can be lifted from the lift point by the boom cylinders with the bucket in rated lift bucket position and the excavator physically restrained from tipping. 3.9.1 boom hydrau
20、lic lift capacity: Load that can be lifted by applying working circuit pressure to the boom cylinder(s) without exceeding holding circuit pressure in any other circuit. 3.9.2 arm hydraulic lift capacity: Load that can be lifted by applying working circuit pressure to the arm 1 Copyright Internationa

23、 lift capacity (3.10). 4 Calculations 4.1 Tipping load calculations A series of calculations at various lift radii is made to determine the load required to achieve the bal- ance point as defined in 3.5. Sufficient lift radii shall be considered to develop the rated lift capacity chart (see annex A)
24、. Lift point positions shall be included above and below the ground reference plane, over the ends and the sides of the machine, and with the machine in the configuration that results in the low- est moment available to resist overturning. 4.1.1 Machine configuration for calculations 4.1.1.1 Because
