This choice must be made in relation to the real service performance required as well as the environmental conditions in which the jib crane will have to operate. § The parameters which must be carefully considered in the choice of jib crane are: The lifting capacity: this must be determined by the weight of the maximum load to be lifted and must never be. The functional dimensions : the height of the arm which determines the hook run of the hoist and the range must be selected so as to guarantee the functional coverage of the space to be used considering the surrounding clearance The nature of the load : the nature of the load determines for its positioning the choice of the speeds of movement (lifting) suited to the task. In some cases it is indispensable to use two-speed hoists with a slow positioning speed. The area to be used in : the jib crane with articulated arm features in its conception intrinsic high elasticity which becomes even more evident when it is used for moving loads close to the maximum load and/or with prevalent localisation in the ends of the arm. The environment to be used in : the jib cranes with articulated arm are intended for service indoors and/or in a covered area, sheltered from bad weather and away from wind. In the case of use outdoors adequate steps must be taken in relation to the surface treatment (sanding, varnishing) as well as a system of stopping brake. The frequency of use : if the use is very intense (frequent manoeuvres and/or repeated ones) with loads close to the maximum lifting capacity, the consequent fatigue of the operator due to the manual movements must be taken into account. • The correct evaluation of the parameters indicated above, in the case of the parameters being close to the upper limits, can lead to the need to use a crane with higher performance features which, once gone beyond, can guarantee more rigidity and fewer translating and rotating strains. 8
