Prispevek predstavlja analizo koledarskega asa in delovnih uinkov dveh žinic Syncrofalke na Tolminskem. Koledarski as je obravnavan po mednarodni metodologiji IUFRO. Delimo ga na koledarski as delovnega mesta, to je 261 dni,in na koledarski as zunaj delovnega mesta, ki znaša 104 dni letno. Za vsakdan upoštevamo 8 ur, kar velja tudi v slovenski delovni zakonodaji, zato znaša koledarski asi delovnega mesta 2.088 ur letno. Koledarski as je bil spremljan od zaetka julija 2002 do konca marca 2004, skupaj za dve opazovani žinici 1.270 koledarskih dni. V tem asu sta žinici na 79 linijah obratovali skupaj 709 dni, povpreno 204 dni na leto na žinico. Produktivni delovni as, kamor se šteje le spravilo, je znašal v povpreju 132 dni. Povprena dolžina linije, ki je od stolpa do zadnjega škripca v povpreju merila 336 m, je imela 0,62 vmesne podpore na linijo. Povprena razdalja spravila po nosilni vrvi je 208 m, razdalja zbiranja pa dobrih 34 m. Delež linij za spravilo navzgor je 62%. Povprena koliina lesa na ciklus je 1,04 m3 (1,12 t), na linijo pa 300 m3,od tega 83 % listavcev. Spremljanje koledarskega asa, za kar skrbi delovna skupina pri stroju, je dober pripomoek za dolgorono spremljanje in analiziranje niza parametrov uinkovitosti pri delu, doseganja uinkov stroja inprimerjave med stroji ter tudi za obraunavanje opravljenega dela.The article presents an analysis of calendar times and work performance of twoSyncrofalke cable cranes in Slovenia - the Tolminsko region. Calendar time is dealt with in accordance of the international IUFRO methodology. It is divided into workplace time, i.e. 261 days, and non-workplace time, which is 104 days. For each day, 8 hours are taken into account, which is in fact stipulated in the national work legislation, and the workplace time therefore amounts to 2,088 hours per year. Calendar time for the two cable cranes was monitored from the beginning of July 2002 till the end of March 2004, a total of 1,270 calendar days for both cable cranes. During this time, the cable cranes operated 709 days on 79 lines, or 204 days per cable crane annually, 132 of these for skidding. Average line length, which from the tower to the last tailblock measured 305 m on average, had 0.62 intermediate support per line. Average yarding distance per skyline was 208 m, the bunching distance 34m. The share of uphill yarding lines was 62 %. Average volume of wood was 1.04 m3 (1.12 t) per cycle and 300 m3 per line, 83 % of which went to deciduous trees. Calendar time monitoring, which was carried out by the cable crane crew, is a good expedient for long-term monitoring and analyses of a series of parameters of work performance, of the effects achieved by the machine, for comparisons between different machines, and for the final assessment of work payment
