a) designed in accordance with the usual engineering practice and calculation methods, including all failure modes; b) of sound mechanical and electrical construction; c) made of materials with adequate strength and of suitable quality. 1 Scope This European Standard specifies technical safety requirements and measures for mobile or movable jacks (see 3.6) and associated lifting equipment. This European Standard deals with all significant hazards pertinent to mobile or movable jacks and associated lifting equipment when they are used as intended and under the conditions foreseen by the manufacturer. This European Standard specifies the appropriate technical measures to eliminate or reduce risks arising from the significant hazards. This standard applies to lifting equipment (see 3.1) which are mobile or movable and designed to operate under the load, whether operated singulary or in multiples to partially or totally raise and lower loads or vehicles at one or more lifting points (excluding the lifting of persons) where working under the raised load is not permitted unless additional means of securing the load in position are in place. SIST EN 1494:2002+A1:2009

lifting equipment device which permits a load to be raised, lowered or moved. Lifting equipments within the meaning of this standard are: 3.1.1 mechanical jack Jack in which the load is moved by means of mechanical devices, e. g. rack and pinion jack, screw type bottle jack or mechanical elevator such as a mechanical transmission jack. The jack can also be equipped with claws. SIST EN 1494:2002+A1:2009

hold to run control control device which initiates and maintains operation of machine elements only as long as the manual control (actuator) is actuated and the manual control (actuator) automatically returns to the stop position when released !(see 3.26.3 of EN ISO 12100-1:2003)" 3.8 Braking of the load supporting device 3.8.1 automatic brake Braking device which is normally held on and which is released only by application of power. Operation is also instigated automatically by releasing the controls of the jack and by interruption of the power supply. 3.8.2 self braking drive drive to stop automatically the movement of the load supporting device, as well unloaded as loaded with rated load, also after running-in, e. g. by a self braking spindle 3.8.3 load pressure brake the braking force depends on the load and increases proportionally to the load 3.9
