Abstract

The EXP-2000 is a multipurpose equipment designed for use in logging operation. especially for loading and skidding of logs. In the first trial conducted in 2001, the productivity of EXP-2000 turned out to be very low i.e. 0.872 m3hm/hour. The investment cost of EXP-2000 was about Rp 67.5 million so the cost of operation was Rp. 28,736.25 per hour. After improvement in the performance has been improved: skidding productivity was increased to 3.293 m3.hm/hour and production cost of was reduced Rp 8. 725.29 per m3.In loading operation, the performance of EXP-2000 has been improved by increasing productivity from 3.293 m3.hm/hour to 34.705 m3/hour and decreasing the cost from Rp. 5,315 per m3 to Rp. 828.03 per m3. It means that the implementation of a new improved EXP-2000 is promising both technically and economically due to higher productivity compared to that of using animal (buffalo) and conventional skyline system previously developed by the Research and Development Center for Forest Product Technology, Bogor - Indonesia.

Abstract

Loading  and unloading works are intermediary activities in the logging operation.  The logs after being felled/cut down in the forest will be of economic values when they cannot be brought to the inherent processing industrie. Light­weight and small­size logs favor manual work in their handling as  long  as  man power  is available. Heavy­weight and  large­size  logs, however,  necessitate an auxiliary heavy­duty equipment,  since the manual work is sometimes no longer effective for loading­related operation, e.g. hoisting, placing, regulating their position, etc. The unloading of such logs, conversely, turns out to be easier, but can pose a dangerous threat. Therefore, cautious care is necessary.In dealing with loading/unloading problems as such particularly in plantation forest,  a special equipment that is simple in design has been devised, called as Exp­2000. The equipment, wich is powered by 11­HP's diesel engine, can also perform the skidding­operation.  The overall cost in devising the Exp­2000 's equipment  was Rp. 50,000,000. The trial test as performed on the equipment revealed the following results:                                                                     .The average loading and loading productivities were consecutively 9.54 m3 per hour and  13.18 m3 per hour.Cost of loading as well as unloading was Rp. 1.597,48 per m3.The average skidding productivity was 0.5053 m3.hm/hour with skidding cost at Rp 30,160 per m3.The skidding cost might be reduced to Rp.  21,165 per  m3  and concurrently the productivity increased to 2.25 m3per hour,  if the more powerful diesel engine,  e.g.  25 HP were used.
