Vattenlogistik vid stubbehandling i slutavverkning
Water logistics has long been a problem in order to effectively carry out stump treatment in both thinning and final felling. It is important that the stump treatment?
equipment is configured as well as a sufficient amount of water is carried out on the harvester to get a cost? effective treatment. The flow control of the equipment has improved and water can be dispensed more efficient, but still the amount of water on the machine is a crucial factor in the total cost estimate.
The knowledge of the tools available to bring water as well as the internal logistics of loading and transport to the felling site is deficient. Increased focus on "smart" solutions to manage water cost is of great importance in order to combat Hetrobasidion spp in both thinning and final felling.
The purpose of the study is to describe and summarize different solutions of water logistics at stump treatment in final felling. Holmen Skog's goal is to find good
ways and a possible equipment to get a cost? effective solution of water logistics. The two contractors Thörnwalls and MJN have developed their own ways to get an effective water logistics and their solutions will be studied in more detail.
The results of the study show that the duration of Thörnwalls water logistics requires about 50 minutes per working day. The water Logistics of MJN requires about 20 minutes per working day. Both contractors have developed a water logistics with a few and effective moments. Thörnwalls has managed to develop a way to work that is free from physical handling of water, MJN have the same
goal.
To get an efficient water logistics requires primarily an approach based on procedures and division of responsibility. The equipment must be properly adjusted
and all the physical lifting moments with water should be avoided to make logistics easy and efficient.
