检衡车的重块是用铸铁制造的,其重量最轻的为1700公斤,最重的达4500公斤;其厚度为210毫米,长度为2000毫米,阔度则按照重量不同而变.为了使重块很好地稳装在检衡车上,每块重块均有4孔,孔径为25毫米,以便使用螺丝紧固在车底架的各梁上.由于铁块厚,螺丝孔小,如钻孔加工则吊运很不方便,如使用油砂及普通芯砂作泥芯,则浇注后清砂极不容 Check the weight of the truck is made of cast iron, the lightest weight of 1700 kg, the heaviest of 4500 kg; the thickness of 210 mm, a length of 2000 mm, the width varies according to weight in order to make The weights are well mounted on the counterbalanced truck with 4 holes for each weight and a 25 mm hole diameter to allow the use of screws to fasten the beams to the chassis frame.Because the iron is thick and the screw holes are small, Such as drilling processing is very inconvenient lifting, such as the use of oil sand and ordinary core sand for mud core, after pouring very clear sand
