Earthwork Haul-Truck Cycle-Time Monitoring – A Case Study
change in cycle time has the potential to improve the efficiency of earthwork operations. While this study demonstrated a relatively simple approach to cycle-time monitoring and statistical analysis, a more comprehensively designed monitoring program should be devised to capture the effects of the many factors that can influence productivity.

Influence of Crushed Rock Properties on the Productivity
Among many factors that influence an excavator's performance and productivity, the volume of the bucket load and duration of the excavator working cycle are crucial. In this paper, both factors were investigated, including the granulometric composition of the excavated material. The volume of material in the bucket was determined by photogrammetric analysis while the excavator cycle time was

Analysis of mathematical model of an excavator manipulator
Apr 26, 2016 · Abstract. Single-bucket excavators improvement is closely associated with development and introduction of their workflow automatic control systems and with a robotic excavator creation. Thereat, at synthesis of an excavator control system, the robotics approach is widely developed, according to which, the work equipment is considered as spatial manipulator with hydraulic actu ator.

Jan 01, 2021 · Based on this ratio, we can establish that only the cycle time and the required bucket capacity depend on a particular excavator model. Since in terms of optimizing the payroll costs for operators, the optimal solution is to minimize the number of vehicles in the inventory fleet, we can conclude that the optimal number is the smallest one.
