现有制材厂除钻木车间是半机械化、半手工操作外,其它工序,如原木卸火车、成材装火车、原木归楞,成材垜积,原木进入钻木车间、成材运输等多为手工操作,大部分为重体力劳动,需要劳动力很多,生产效率很低。自开展“双革”以来,各地出现了一些土法装、卸车机械化和运输自动化的经验。如图们制材厂,过去用手工操作需15人一小时半卸一个火车皮的原木,经创制木制门式卸车机后,80分钟可同时卸五个火车皮的原木,平均三人十六分钟卸一个车皮,劳动力减少80%,效率提高4.6倍以上。过去装成材需十二个人三小时装一个
Except for the semi-mechanized and semi-manual operation of the existing material factory, the other processes, such as unloading logs, loading trains, returning logs to timber, entering logs into the logs, turning into lumber and other handcraft Most operations are heavy manual labor, which requires a lot of workforce and low productivity. Since the launch of the “double leather”, there have been some experiences of mechanization and transportation automation of earthwork loading and unloading in various places. For example, Tumen Timber Factory used to manually unload wood logs of 15 people for an hour and a half for half an hour. After the wooden gate unloader was created, 80 logs could be used to unload five logs with an average of ten Unloading a wagon in six minutes reduced labor by 80% and increased efficiency by 4.6 times. In the past, twelve people were required to install one for three hours
