疏浚抓斗(Dredginggrabs)主要用于河海挖取污泥、铁板沙、石块，由于水底杂物黏洁阻力大，对材料要求较高。我公司疏浚抓斗采用日本技术，滑轮轴承采用迷宫式密封，大大提高了抓斗的使用寿命。DredginggrabsItismainlyuseddredgethesludge、ironplatesandandcausethestickyresistanceoftheunderwatersundriesisbig,thegrabshouldbemadeinhighqualitymaterials.OurcompanyadoptsJapanesetechnology，Usinglabyrinthseal,pulleybearingandmakesthetimeofuselonger.)
