In the absence of specific recommendations,

10、a new machine should be operated for at least 4 h to ensure proper function of the machine. At the conclusion of this initial Operation, Service and adjust the machine to the specified conditions. 6.3 When testing pneumatic-tyred equipment while operating on tyres, the tyres shall be inflated to wit

11、hin +3 % of the pressure stipulated by the manufacturer, and all wheels shall be in the ahead Position. Conditions for tyre support shall comply with manufacturers requirements. 7.1.3 Locate the crane on the test course in Position for loading and actuate the travel brakes. 6.4 For conducting tests

12、of cranes with outriggers in the “on outriggers” condition, the crane shall be level (G 1% gradient). 7.1.4 Set outriggers, if used, and jack the crane to a Position in which the tyres or tracks within the boundary of the outriggers are unloaded. 6.4.1 When outriggers are used in the course of testi

13、ng pneumatic-tyred cranes, the crane shall be raised by the outriggers so as to provide clearance between the ground and all the wheels or to relieve all wheels of the weight of the crane unless the Suspension design is such that the tyres stay on the ground when outriggers are set. 7.1.5 Vertically

14、 project the superstructure axis-of- rotation onto the surface of the test course and mark its location. 7.2 Test measurements 7.2.1 Prepare test load, including test weights, hook block, Slings and any other ancillary equipment, such as Poad basket, to make up the specified load mass to within + 1

15、%. Record this value. 6.4.2 When outriggers are used in the course of testing crawler cranes, the crane shall be installed so as to ensure firm bearing of the outriggers on the supporting surface. 2 SANS 11662-1:2007This standard may only be used and printed by approved subscription and freemailing

16、clients of the SABS.0 ISO ISO 116621:1995(E) 7.2.2 With the crane superstructure in its least stable configuration for the specified Position, hoist the load free from the test surface at a radius at which the crane is stable; then boom down a small amount to increase the radius. Keep the load withi

17、n 0,l m of the test surface at all times to prevent excessive tipping. If the crane will support the load at the adjusted radius without tipping, measure and record the new radius. Repeat the procedure until the balance Point is reached. When the balance Point is reached, record the mass of the load

18、 and radius of the load. NOTE 1 The final adjustment of the balance Point may be made by adding small increments of mass rather than increasing the radius. 7.2.3 Alternatively, measure the radius of load and add small increments of mass to the load until the load overcomes the stability of the crane

19、. The radius of load and load mass last employed, before the stability of the crane was overcome, shall be recorded as the balance Point condition. 8 Plotting of capacity curve Where it is desired to determine the balance Point capacities of a crane throughout a range of loads or radii, follow proce

20、dures as outlined in 7.2, making Sure that the load and radius are determined for each extreme of the Chosen range and at a sufficient number of intermediate Points to permit plotting a curve. Plot a curve showing the maximum capacity of the crane with the load, in kilograms, as Ordinate and radius,

21、 in metres, as abscissa. Use a representative number of boom lengths for a given capacity Chart. 9 Test report Record a complete description of the crane, positions for the test, data for the tipping load and the radius of load on test data sheets.
