3.2 caterpillar haul-off a device comprising two or more sets of linked elements equipped with gripping segments or lugs; one or more are driven. Grip is achieved when the elements are closed together by pressing the product between them (see figure 1).
3.3 belt haul-off a device comprising two counter-rotating belts set in line one above the other; one or both is driven. Grip is achieved when the belts are closed together by pressing the product between both belts (see figure 2).
3.4 capstan haul-off a device comprising one or more drums or wheels at least one of which is driven. Grip is achieved by the tension of the product, e.g. cables, flexible hoses, wrapped one or more times around the drum(s) or wheel(s) (see figure 3).
3.5 belt capstan haul-off a device comprising a wheel and a belt which covers at least partially the circumference of the wheel. The wheel, the belt or both are driven. Grip is achieved by pressing the product between the belt and the wheel (see figure 4).
3.6 roller haul-off a device comprising one or more sets of counter-rotating rolls set in line one above the other; one roller or both of each set is driven. Grip is achieved by pressing the product between the rollers (see figure 5). SIST EN 1114-3:2001+A1:2008

4 List of significant hazards 4.1 Mechanical Hazards Mechanical Hazards are: a
crushing b
cutting and severing c
shearing d
drawing in or trapping e
falling/uncontrolled descent due to gravity
These hazards are principally due to:  the rotating parts of the drive and power transmission systems (a,b,c,d);  the rotating drive rollers or wheel(s) or drum(s) with or without product (a, b, c, d);  the moving parts of the conveying elements, such as caterpillars, belts, pressure rollers, return rollers, etc. with or without product (a,b,c,d,);  the moving parts of the conveying element mountings during opening and closing (a, e);  movement of the product through feed openings in guards (a,d);  movement of the machine for changes of location (a).
