冬季在严寒地区装卸货物是很困难的。有时,天气坏到装卸人员挖掘货物后才能装卸。特别是某些散装货物,卸车时必须多花时间和费用才能使冻结货物松动。传统的卸货方法,例如解冻和振动,虽然效率高,但设备、维修和燃料要花许多钱,同时还会损坏车辆。 1985年2月,在美国铁路货运公司试验一种新的机械松动装置,该装置是三江起重机公司的产品,可松动漏斗车内冻结的或压实的货物,不致损坏车辆。
Winter loading and unloading of goods in very cold areas is very difficult. Occasionally, the weather is bad until the loading and unloading personnel dig cargo before loading and unloading. In particular, some bulk goods, unloading trucks must spend more time and money to make the frozen goods loose. Traditional methods of unloading, such as thawing and vibration, although efficient, can cost a lot of money for equipment, maintenance and fuel while also damaging the vehicle. In February 1985, at a U.S. railroad freight company, a new mechanical loosening device, a product of Sanjiang Crane Company, was used to loosen the frozen or compacted cargo in the funnel without damaging the vehicle.
