Design and Experiment of the Explosion-proof Electric Mobile Elevating Work Platforms

In order to eliminate security risks in the process of aerial operation in the explosion-proof environment, the new Explosion-proof Electric Mobile Elevating Work Platforms (EEMEWP) were designed. Firstly, the power matching of the hydraulic driving system of the EEMEWP was calculated. Secondly, the dynamic operation performance of the articulating booms of the EEMEWP was analyzed by software ADAMS. Lastly, the field tests including stability test, driving test, operating test and explosion-proof test were carried out. The field tests results show that the EEMEWP have excellent stability and can climb over 20% of the slope in the condition of 300 kg load. The maximum loading capacity errors of the different oil cylinders between the test results and simulation calculation data are less than 8%. The EEMEWP were tested in accordance with Chinese national standards, and the result is satisfied. Now, the EEMEWP have been issued by the dIIBT4 explosion-proof certification.
