为了解决人工林和天然次生林抚育间伐缺少集材机械的问题,自1977年起由我所研究、设计并试制了营林35集材机的第一轮样机。经过改进后,由绥化林业机械厂试制了第二轮样机。样机通过八百负荷小时的生产试验和强度、性能测试,证明牵引能力、行驶速度、拖载量、通过性能、爬坡能力,以及转向和工作装置等主要技术性能均达到了设计要求。于1980年5月经林业部机械局批准,由黑龙江省林业总局主持鉴定,同意进行批量生产。根据鉴定会意见,我们修改了设计图纸,绥化林业机械厂在1980年下半年投入小批量(30台)生产,年底已组装完毕。
In order to solve the problem of lack of skid machinery in tending of forests and natural secondary forests, I have studied, designed and piloted the first round prototype of the 35th skidder since 1977. After the improvement, the second round of prototype was made by Suihua Forestry Machinery Factory. The prototype passed eight hundred load hours of production test and strength and performance tests to prove that the main technical performances such as traction ability, running speed, tow load capacity, passing performance, gradeability, and steering and working devices all met the design requirements. Approved by the Machinery Bureau of the Ministry of Forestry in May 1980, the Heilongjiang Provincial General Administration of Forestry presided over the appraisal and agreed to conduct mass production. According to the opinions of the appraisal meeting, we revised the design drawings. The Suihua Forestry Machinery Factory invested in small batches (30 sets) of production in the second half of 1980 and it has been assembled at the end of the year.
