Trunking components andadditional elementsDepending on the different installation requirementsZucchini can provide various technical solutions:a) curved elements: available for making changes ofdirection (only horizontally) up to a minimum radiusof curvature of 1.5m. There is a quick connection,as with the straight elements. Standard trolleys slideefficiently even within the curved sections of the line.The standard degree of protection is IP20;b) straight elements with trolley introduction device:these elements are provided with an access dooron the underside. With this door open, it is possibleto insert or remove a trolley from the line. Trolleyscan generally be put into the line near the endcovers. However, when there are lines with severaloperating trolleys or when using very long lines, it isrecommended to use an inserting centre element tomake maintenance operations on the trolleys easier.The standard degree of protection is IP20;c) straight lengths with thermal expansion device.These elements are necessary in lines exceeding35-40 m in length. Expansion elements absorb andcompensate the thermal expansion of the conductorspreventing them from losing their linearity, avoidingthe reduction of the air insulation distances andobstructing the sliding action of the trolleys.The end covercompletes theinstallation of thelines and guaranteesthe IP20 degree ofprotection of the line.The suspension bracket canbe positioned anywherealong the busbar.Straight elements.PARTS OF THE LINEEnd feed unitEnd coverElectrical and mechanical jointSuspension and joint bracket114 MR TS -- TROLLEY MEDIUM SYSTEM RATING
