Possible differences in the performances of vibration-reducing gloves when used with hammers of different sizes.

Protection provided by vibration-reducing gloves (VR) when used with impact tools can be considerably different from that measured following the ISO 10819 Standard. This paper investigates the transmissibility, at the palm level, of three different types of vibration-reducing gloves (air bubbles; gel; neoprene) and a working leather glove, while using 8 different models of electro-pneumatic hammers for chiseling rock in a limestone quarry plant. The capability to reduce the triaxial vibration as the average of all the tested hammers results limited: 12 % for both the gloves in gel and neoprene, and 7 % for the glove in air.

Problems related to measuring the transmissibility of anti-vibration gloves: possible efficacy for impact tools used in mining and quarrying activities.

This article takes into account some of the most relevant studies investigating the transmissibility of anti-vibration (AV) gloves. AV gloves are almost useless at the palm level in the low frequencies (<31.5 Hz), while they generally start to have an appreciable reduction of the vibration over 400 Hz.

Preliminary Investigation on Systems for the Preventive Diagnosis of Faults on Agricultural Operating Machines.

This paper aims to investigate failures induced by vibrations on machines, focusing on agricultural ones. The research on literature has brought to light a considerable amount of data on the driven vehicles and not much on the operating machines, including the ones that we looked for. For this reason, it was decided to direct a survey with the people who work with agricultural machinery every day: operators, sub-contractors, and producers.
