Risk-taking in the crane driver - crane system
Risikoverhalten im innerbetrieblichen Transportsystem Kranführer-Kran [in German]
Doctorate thesis, the 1st part of which studies risk-taking behaviour and its impact on the crane driver - crane system (ore-loading ramp) in an iron and steel plant: literature survey; determination of the nature of risk-taking behaviour by drivers of an overhead travelling crane; study of the influence of individual characteristics; influence of risk-taking on the work performance of the crane driver. The second part is devoted to studying risk-taking behaviour contrary to the interests of safety during lifting or setting down of the load (accident black spot), by way of an analysis of the man-machine system. Study of the psychological possibilities of influencing unsafe work behaviour, and of the efficacy of instruction as a preventive measure. In practice, a decline in cases of unsafe behaviour has been observed after instruction of the crane driver - slinger team.

Overhead travelling cranes operated from the ground
La commande au sol des ponts roulants [in French]
After comparing the advantages and disadvantages of ground control as opposed to cabin control and describing the features of push-button pendants, some of which are very complicated to operate, the author analyses, on the basis of typical accident reports, the hazards involved in ground-level operation of these cranes, indicating appropriate preventive measures: hazards due to equipment or its design (error in observing movements, errors in orientation, lack of adaptation of travelling and crab speeds to this new method of operation); other hazards associated with the workplaces where the cranes are used; hazards due to inadequate training of crane operators. A draft French standard (E 52-124) is appended; it specifies the layout, colours and differential symbols to be used on push-button pendants.

Long-term mortality study of steelworkers.
Report of a study of the cause-specific mortality of 4,588 crane operators employed in the steel industry during the period 1953-1966. Their mortality experience is contrasted with the mortality predicted by the age- and race-specific rates for a control group of steelworkers who were never cranemen. The most important observations are: (1) cranemen show no excess risk of dying from lung cancer; (2) white crane operators show an overall excess risk of dying from cardiovascular and renal diseases. Further research into the relationship between crane jobs and mortality from cardiovascular and renal diseases is suggested.

SYTLYN - A program for sight line calculation.
A well-illustrated description of a new system for assessing visibility in the design and siting of work stations (such as crane cabs). A review of existing methods (graphic techniques, physical models) is followed by an account of the SYTLYN system, which is based on a computer programmed to produce drawings in a form that gives a 360° view. The result is a clear and relatively simple presentation; detailed designs can be produced rapidly from a specification of visibility needs and the sizes and shapes of the machines and other objects involved. Particular applicability is foreseen in the steel industry and wherever large semi-automatic machines are monitored by one operator. Such a programme should contribute to safety and productivity when used at the design stage.

CIS 73-51 An intuitive control box for overhead travelling cranes
Une boîte de commande intuitive pour la conduite des ponts roulants [in French]
Conventional push-button control boxes are poorly suited to controlling overhead travelling cranes from the ground. The system developed by the French National Research and Safety Institute makes use of the operator's instinctive and intuitive reactions, even though he has not been taught how to use the controls. The control box is operated by a single hand. No matter what the operator's position, actuation of a given key will always produce the same load movement. To move the load in a given direction, the operator actuates the control device in the same direction. The orientation of the box in relation to the hoisting equipment is held constant by the non-twist suspension - the box is shaped like an elongated prism with an octagonal cross-section and contains the contacts; the pyramid-shaped hollow base contains 4 keys which control travel and a vertically displaceable disc for raising and lowering.

CIS 73-677 Safer monorail hoists
Säkrare travers [in Swedish]
The conventional suspended push-button control box for monorail hoists has the disadvantage of occupying both the operator's hands and makes it impossible for him to use one hand to guide the load; in addition, there is a possibility of the operator pressing the wrong button with all its dangerous consequences. A control device has been developed in Sweden which can even be operated by a person wearing safety gloves. The device consists of a control hoop in which rotates a ring across which is fixed a rotating control grip. 2 buttons on the hoop control the lateral travel of the monorail. The unilateral arrangement of the buttons eliminates all possibility of operating error.

Notes concerning motorised cranes - Critical axial load - Calculating the strength of lattice jibs
Note sulle autogru - Carico di punta - Considerazioni - Calcolo di verifica del braccio a traliccio [in Italian]
Increasingly bigger self-propelled cranes are being constructed, and their component parts are tending to be increasingly lighter; thus the risk of sudden buckling due to elastic instability is becoming more prevalent.
