Text Complet
This work begins with a request of the company Arcelor Mittal in the Gent factory. An assessment of the comfort situation on their cabin cranes pointed out that the vibrational comfort levels are near the action levels stipulated in the European norm (ISO 2631/1). In order to improve the working comfort of the overhead crane operators the company implemented a cabin suspension that showed no actual improvement. The aim of this work is to deliver a detailed analysis of the low-frequency vibrational comfort of the overhead cabin cranes. To do so several vibration measurements have to be taken and analysed. After the analysis the company may decide to study a new suspension design knowing which vibration needs to be attenuated ​
