Many sections of the Handbooks include tables or curves showing cycle times or hourly production figures for the Original Equipment Manufacturers equipment under certain conditions. Statements of conditions always accompany or precede the curves or tables. Before using any performance information in any Handbook, a complete understanding of the qualifying conditions is essential.

In general the data contained in the various Performance And Specifications Handbooks are based on field testing, computer analysis, laboratory research and experience including field trials and testing. However, the published data is usually based upon 100% efficiency in operation a status which cannot be achieved continuously even under ideal conditions. When using the performance and production data in the various Performance Handbooks correction factor must be applied to the results indicated in the handbook tables.

The factors should allow for the material characteristics, altitude, anticipated actual job efficiency, operator efficiency, haul road conditions and other relevant local factors that may reduce performance or production on a particular job.

Specifications shown in the Handbook were current at time of publishing but as most Equipment Manufacturers have active equipment improvement programs, specifications and materials may change without notice. For current specifications relating to a particular machines performance always check with a local representative or distributor to confirm the currency and accuracy of the details in the Performance Handbook.

Included in the Owning and Operating Section are guidelines, based on working conditions, to assist in estimating consumption of fuel and lubricants, tire life and repair costs for the various items of equipment.

As far as I am aware Liebherr do not have a Handbook any more. Just individual pamphlets on equipment and some other bits and pieces. I have a hardcopy from 1992 (that old!!) and when I checked with the local manager some time ago for an update he couldnt help with either a soft or hard copy version.

Havent been able to get a copy of a consolidated handbook. The link on the page above or the following may help. http://www.hitachiconstruction.com/service-support/late-model-brochures/mining-brochures/ Regards Roger
