摘要:

对林用装卸桥来说,提前报废或通过强行修理、任意延长其使用期,都是不科学、不可取的。通过调查福建林区林用装卸桥的实际使用情况,运用数理统计方法,在分析林用装卸桥平均直接生产成本、各年累计作业量和使用年限之间关系的基础上,得到年平均单位作业成本与使用年限之间的数学模型。并根据该模型,可计算出林用装卸桥在10~15a期间,其年平均单位作业成本比较低。因此,可以认为10~15a为其经济使用年限区间。

关键词: 林用装卸桥, 合理更新期, 单位作业成本, 使用年限

Abstract:

Based on the analyses on the relationships between average direct operation cost,accumulative total operation volumes and the years used of gantry crane for forestry used in Fujian,the proper regeneration time of gantry crane for forestry was calculated in the paper.The results showed that the proper regeneration time of gantry crane for forestry used in Fujian should be 10~15 year.

Key words: Gantry crane for forestry, Proper regeneration time, Operation costs per unit, Year used
