Liming · curves showing cycle times or hourly production fig-ures for Caterpillar machines under certain con-ditions. Statements of conditions always accompany or precede the curves or tables. Before using any per-formance information in this Handbook, a complete understanding of the qualifying conditions is essential.

Liming · Under real site conditions with many related factors such as management, environmental, site conditions, cycle times of a hauling unit (dump truck) was observed and illustrated in Fig. 1. This graph depicts 59 cycles per day for one dump truck in an excavation crew. Fig. 1. Distribution of 59 cycle times of one dump truck per day.
Liming · What is the impact of poor haul truck cycle time performance? Wait at shovel Load Travel loaded Dump Return to shovel 1 minute 2 minutes 1 minute 3.5 minutes 2.8 minutes 10.5 minutes 1.6 minutes 9.2 minutes Actual site averages… Leading practice targets (240 t trucks) Potential latent capacity: 2.5 mins
Liming · Truck Body Systems Caterpillar designed and built for the toughest mining applications. Cat Truck Bodies Matching the truck body to the application is a critical part of achieving the best value from your 785D. Caterpillar offers a variety of application speciic body options that yield a payload ranging from 131 to 143 metric tons (144 to 157
Liming · Prior to loading, all dump trucks will be staged as described in Section 3.0 below. Traffic will be coordinated in such a manner that, at any given time, no more than three dump trucks will be waiting to be loaded within, or adjacent to, the work area. Upon entering the Removal Area, all vehicles will be required to maintain slow speeds (i.e.,
Liming · The speed of the trucks in the ET distance (Normal PDF Speed) considers low, medium and high vehicular flows for its PDF parameters. These three levels are also used for the Normal PDF parameters of the delays or waiting times of the trucks at the intersections (I1 and I2) leading into the excavation or dump zones (Normal PDF Delay). 4.5.

Liming · - Width of the excavation, Depth of the cut, Material type, Working radius for digging average of 85 percent. Step 2. Use a hoe cycle time based on past performance data if available or use the average cycle time given Step 3. Determine the ideal production rate (LCY per hour). Dump Truck Trick of Trade #1: Number of Trucks Required
Liming · Dump Truck Bodies AUSTIN ENGINEERING IS THE DESIGNER AND MANUFACTURER OF WESTECH, JEC AND ULTIMA DUMP TRUCK BODIES AS WELL AS OEM DESIGNED BODIES. Our dump truck bodies are custom engineered for all makes and models of trucks and applications. We use a unique mix of steel plate during our monitored …
Liming · Cycle times can be one of the more puzzling aspects of open-pit mining. De-pending on one's perspective, the term has several connotations. A mine meas-ures cycle times to determine equipment performance as well as operator effi-ciency . Unusually, high readings of cycle time in certain segments highlight problems in the process, or
Liming · Life cycle inventory (LCI) is the process of data collection and calculation of the product model. Life cycle impact assessment (LCIA) is a step of classifying and characterising potential environmental impacts based on the LCI results. Interpretation is performed based on the impact assessment results and gives an ana-
The example above considered a 25% truck factor and the average payload set is 200 t. Defining a 25% truck factor means that every time the weightometer measures a load lower than 25% of the average set, the dispatch system will automatically create a new record in which the average is the value and it becomes then the official load.
Liming · Excavation and embankment (cut and fill) Excavation = the removal of soil or rock from its natural location. Embankment = the placement and compaction of layers of earth or rock to form a roadbed of the planned shape, density, and profile grade. Various sections of a roadway design will require bringing in earth.
Earth excavation and grading can be a fascinating part of a construction project. The powerful heavy equipment, used to best advantage by a skilled operator, is a joy to behold. The scope of the excavation job varies from digging footings for a …
