武钢大冶铁矿东露天采场已进入封闭圈60米以下,运输方式从1978年开始由单一电机车运输改为电机车—汽车联合运输。汽车用上海牌SH380A型柴油自卸车,高温季节驾驶室温度高达48℃,粉尘浓度也超过国家卫生标准,危害工人身体健康,影响生产效率的提高。为改善驾驶室的作业条件,考虑到矿用汽车驾驶室空间小、震动剧烈和没有交流电源等特点,选用上海沪江电机厂试制的解体式冷气装置,在国产上海牌32吨重型自卸汽
The open pit of Daye Iron Mine in WISCO has entered the closed circle of 60 meters or less. Since 1978, the transport mode has been changed from single electric locomotive to electric locomotive-car combined transport. Shanghai SH380A Diesel Dump Truck with high temperature season cab temperature up to 48 ℃, the dust concentration also exceeded the national health standards, endangering the health of workers, affecting the production efficiency. In order to improve the operating conditions of the cab, taking into account the mining car cab space is small, severe vibration and no AC power supply characteristics, the selection of Shanghai Shanghai Electric Factory trial production of disassembled air-conditioning unit, made in Shanghai brand 32 tons of heavy dump
