遵照毛主席关于“独立自主,自力更生”的教导,广西林业科学研究所和广西柳州林机修造厂的工人、科技人员,共同深入林区,调查研究,广泛听取林区工人、贫下中农意见,根据我区木材生产特点,共同设计、试制成功一种新式液压绞盘机。该机有两个缠绕卷筒,一个摩擦卷筒,可作伐木场集材,运材索道驱动机,还可以用作装车、贮木场作业等。该机采用液压传动,达到无级变速,操纵灵活。回空卷筒采用链传动,减轻重量,降低制造成本。控制系统装有安全阀,防止过载,因而工作安全、可靠。主要技术参数: 发动机:2105型柴油机,26马力,1,500转/分液压泵:ZB-40,1,500转/分,40厘米~3/转,210公斤/厘米~2
Following Chairman Mao’s teachings on “independence and self-reliance”, Guangxi Academy of Forestry and Guangxi Liuzhou Forestry Machine Repair Factory workers and technicians went deep into the forest area to conduct investigations and studies. They listened extensively to the opinions of forest workers and poor peasants and poor peasants, District timber production characteristics, joint design, trial success of a new type of hydraulic winch machine. The machine has two winding drums, a friction drum, can be used for logging timber skidding, timbering rope drive, but also can be used as loading, storage yard operations. The machine uses hydraulic transmission, to achieve infinitely variable speed, flexible operation. Back to the empty reel chain drive, reduce weight and reduce manufacturing costs. Control system equipped with safety valve to prevent overload, so work safe and reliable. Main technical parameters: Engine: Model 2105 diesel engine, 26 hp, 1,500 rpm Hydraulic pump: ZB-40, 1,500 rpm, 40 cm 3 / rev, 210 kg / cm 2
