Study on Methodology for Detecting the Status of General Excavator without Renovation

Abstract

Excavation and earthmoving equipment mostly operate in accident-prone areas. These areas normally have rollover, confinement, and fall or may be considered harmful work areas due to demolitions and sewage removals. It is inevitable that excavation and earthmoving systems should be developed to secure the safety of operators through unmanned and remote control systems. Therefore, this research proposes a system that enables excavators to be unmanned and remote controlled without any renovation, remodeling, change, or transformation by applying attachable and separable mechanism and modules. Moreover, this research proposes the sensor module to evaluate the dynamic status without processing remodeling or transformation the existing hydraulic drive excavation system by adopting the easy attachable and separable mechanism. The study verifies this proposal based on observed possibility and feasibility through the experiments.

Opposing influences on construction plant and machinery health and safety innovations

“…• improvement of operator protection from overturn, using optimally designed protective structures (Karliński et al, 2008); • machine "pose" estimation to help avoid excavator collisions (Feng et al, 2015); • radio-frequency identification for correct choice and safer use of excavator attachments (Rinneberg et al, 2015); • work environment analysis to design safer plant motion (Lei et al, 2014;Hammad et al, 2015, Vahdatikhaki andHammad 2015a;Zhang et al, 2015); • object tracking to mitigate machine contact incidents Caldas, 2010, 2012;Vahdatikhaki and Hammad, 2015b); • proximity detection for avoidance of "struck-by" incidents (Teizer et al, 2010(Teizer et al, , 2015Teizer, 2015aTeizer, , 2015b; and • electronic remote control for "autonomous" P&M (Yamamoto et al, 2009;Kang et al, 2013;Trung et al, 2013;Lee et al, 2015).…”
