Dangerous Sources in Construction Dangerous sources involve in construction that mainly associate with the construction divisional and partial (process) engineering, the construction installation (facility, machinery), and the material.
Flight drop, messy pile and people strike happen in the course of piling and moving instruction material, member and installment.
It is necessary to provide the essential individual protection materials as providing the qualified safety belt and the safety nut for workers in the basis of the regulation.

Application of Orthogonal Experiments in Simulation and Optimization of Jaw Crusher on Traveling Characteristic Value of Moving Jaw Lizhen Zhanga, Xiaoqing Shenb, Shouqi Caoc,Chao Lvd College of Engineering Science & Technology, Shanghai Ocean University, 999 Hucheng Ring Road, Lingang New City, Shanghai 201306, China alzzhang@shou.edu.cn, bshenxiaoqing2006@hotmail.com, csqcao@shou.edu.cn, dclv@shou.edu.cn Keywords: Jaw crusher; Orthogonal experiment; Traveling characteristic vale of moving jaw.
The moving jaw moves upwards to the fixed jaw when the angle between toggle plate and moving jaw increases, crushing materials in the process.
The moving jaw is pushed downwards from the fixed jaw by a pulling rod and spring when the angle between toggle plate and moving jaw decreases, discharging the final crushed materials from the outlet.
The moving jaw is moved periodically by the eccentric shaft to continuously crush and discharges materials from the crushing chamber [1-3].

The resulting nuclear-density maps have reconfirmed that Cu1–Cu2 chains are the main conduction pathways in this material, as previously suggested from the Rietveld analysis of neutron powder diffraction data.
