Crane accidents by contact with powerlines
Reports of electrocution accidents involving contact between machines and powerlines were analysed to determine the type of equipment involved, the occupation of the workers affected, the severity of the accident, the part of the machine which came into contact with the powerline and the voltage of the powerline. Based on this analysis, some specific factors have been recognised which have helped to describe some typical accidents for each of six categories of equipment. The study can be used to define a priority for the prevention of this type of accident, including consideration of the technology of the machines involved.

Technical characteristics of overhead cranes influencing the vibration exposure of the operators
This study was undertaken to determine the technical factors responsible for the generation of vibration and shocks in overhead cranes and therefore responsible for complaints by the workers. Vibration measurements were made on the floor and on the seat of the cabin on 21 cranes. Vibration levels were correlated with the characteristics of the cranes. The study showed that vibration accelerations increased with the span of the crane and were very dependent upon the state of the runway. The type of speed regulation and the position of the cabin also play a significant role. The suspension systems of the cabin and of the seat were clearly inadequate to give significant reduction of the vibration. In several cases, it was even shown to amplify the vibration in the most critical frequency range. These results should be taken into account by designers as well as maintenance services in order to prevent the development of vibration at the source.

Vibration exposure in overhead cranes
Exposition aux vibrations dans les ponts roulants [in French]
A study was undertaken in order to determine the technical characteristics of overhead cranes that may be responsible for the generation of vibration and shocks, and the most appropriate ways to reduce this exposure. It clearly demonstrates the importance of the crane track, and of the dimensions and suspension systems of the cabin and seat. The opinions of the workers concerning vibration and shocks were analysed, demonstrating that workers have difficulty discriminating between vibration and shock. The nuisance threshold appeared to be about 0.6m/s2. The prevalence of low-back pain was also compared between overhead crane operators and a control group formed of subjects adopting almost the same working postures but not exposed to vibration. This study did not reveal any increase in prevalence that could be attributed to whole-body exposure.

Spinal disorders among Venice port crane operators
Prevalenza di spondilopatie tra i gruisti del porto di Venezia [in Italian]
A group of 78 crane operators were examined using the "EPM Research Unit" method for assessing spine function. Crane operators work in a fixed posture characterised by a flexed position of the cervical spine, isometric load of the extensor cervical muscles and increased dorsal kyphosis. The prevalence of spinal disorders was 39.7% for the cervical tract, 37.2% for the dorsal tract and 38.5% for the lumbar region. The results were compared with those concerning a control group. A statistically significant difference was found in the number of cervical and dorsal complaints (OR=3.33 and 2.69), whereas the difference was nearly significant for the lumbar tract (OR=1.65). Results suggest that this category of workers may be subject to an increased risk for the spine.

CIS 90-1532 Radical solutions are needed
Nužny radikal'nye rešenija [in Russian]
Editorial presenting fatal accident statistics for mining, metallurgy, petroleum and gas extraction, petroleum refining, the chemical and petrochemical industry and geological exploration, as well as for cranes and for equipment subject to the boiler and gas inspectorates in the USSR for 1988 and 1989. Although there were 89 fewer deaths in 1989 (1151 versus 1240 in 1988), the decrease is modest, and there was actually an increase in the petroleum and gas industry. The numbers are broken down by industrial sector and republic; total figures for the Russian, Ukrainian and Kazakh republics are broken down by district. The relation of these figures to the safety situation in general is discussed. Improvement requires action on 3 fronts: increasing the safety consciousness of the whole population; imposing serious fines on those who violate safety rules; establishment of a legal and regulatory system that clearly defines the rights and responsibilities of individuals, enterprises and authorities.

Escape devices for cranes
Ėvakuacionnye ustrojstva dlja gruzopod"emnyh kranov [in Russian]
Illustrated description of 2 compact and effective means of escape for operators of cranes. One is a reel of steel tape or nylon strap attached to a hydraulic clutch. The clutch limits the rate at which the reel can unwind to 3m/s. The tape or strap has a ring at the free end for attachment of a safety belt or harness. It can lower persons over distances up to 35m. The other device consists of a double-walled fabric tube that descends from a hole in the floor of the operator's cabin or from another appropriate point on the crane. The outer tube is 360-420mm in width and is elastic in the radial direction but not longitudinally; the inner tube is 870-920mm wide and is not elastic in either dimension. The rate of descent of a person through the tube is controlled by friction between his clothing and the inner tube, and by the mechanical properties of the double-walled structure.

Back disorders in crane operators exposed to whole-body vibration
The incidence of permanent work disability due to whole-body vibration among 743 crane operators and 662 controls in the Netherlands was studied. There were more disabilities among crane operators with more than 5 years of exposure to vibrations than in the control group. With increasing years of exposure the risk ratio for disability due to intervertebral disc disorders increased. Regression analysis yielded a 1.5-fold rise in risk of disability for 10 years of vibration exposure.

Contactless travel-limiting device for cranes
Beskontaktnyj ograničitel' hoda krana [in Russian]
Description and block diagram of a travel-limiting device for portal cranes. Each of 2 cranes mounted on a single set of rails is equipped with a transmitter/receiver unit and a reflector. At the minimal distance between the cranes, the reflector on each is aligned with the transmitter/receiver unit on the other. This allows a beam of light from a photodiode in the transmitter to be reflected back to a detector in the receiver. The detector is connected via electronic circuitry to a relay that brings the crane to a halt when the detector picks up the reflected light.
