Devices for controlling movements shall act in such a way that the machinery or related product on which they are installed is kept safe.
- a)Machinery or related products shall be designed and constructed or fitted with devices in such a way that the amplitude of movement of its components is kept within the specified limits. The operation of such devices shall, where appropriate, be preceded by a warning;
- b)Where several fixed or rail-mounted machinery or related products can be manoeuvred simultaneously in the same place, with risks of collision, such machinery shall be designed and constructed in such a way as to make it possible to fit systems enabling these risks to be avoided;
- c)Machinery or related products shall be designed and constructed in such a way that the loads cannot creep dangerously or fall freely and unexpectedly, even in the event of partial or total failure of the power supply or when the operator stops operating the machinery;
- d)It shall not be possible, under normal operating conditions, to lower the load solely by friction brake, except in the case of machinery or related products whose function requires it to operate in that way;
- e)Holding devices shall be designed and constructed in such a way that inadvertent dropping of the loads is avoided.
