Our grab nickel production, nickel is mainly used to crawl Hard fine powder , red clay minerals such as highly viscous due to the recent nickel Hard fine powder , red clay and other minerals to be widely used, so Many major ports on the existence of such a problem, in which the ore handling when loading and unloading there is a low efficiency, has been a lot of ore grab adhesive wall, our company in order to solve this dilemma has been studied and produced by such a professional crawl very sticky ore grab, the principle is: grab the lowbeam calculated to increase the adoption of two pieces of solder, including the specific location of board and grab the bucket to create a circular flap, so Open grab discharging, the fight is on board, including the body wall from the top down (no contact with body panels Doo), to stick the body in fighting the viscous wall down, including mine, so, which greatly improved the handling grab the efficiency of ports and factories to solve the problem, which is purpuratus grab a patent, other manufacturers can not be produced.

我公司生产的镍矿抓斗，主要用来抓取镍矿、铁精粉、红粘土等粘性很强的矿石，由于近来镍矿、铁精粉、红粘土等矿石在被人们广泛使用，因此，许多大港口就存在着这样一个问题，在装卸这此矿石的时候，存在着装卸效率低，抓斗内壁被很多矿石粘着，我公司为了解决这一难题，现已研究并生产出来这种专业抓取很粘的矿石抓斗，原理是：在抓斗的下承梁上通过计算得出要加焊俩块括板的具体位置，并要把抓斗的斗瓣做成圆形，这样在抓斗打开卸料时，括板就在斗体内壁从上而下，把粘在斗体内壁的粘矿括了下来，所以，这就大大提高了抓斗的装卸效率，为港口和工厂解决了这一难题，这种抓斗是紫石的一项专利，其它厂家是无法生产出来的。

Because the underwater operating systems such as the machine drilling shallow stratum core sample in deep sea, the video grab bucket and so on are small and agility, they are capable of exploring and operating in smaller bodies of water in addition to areas of the ocean that would be out of reach for a larger vehicle. Being autonomous requires that the system must be capable of performing without the need for human supervision, so use of external sensors such as sonar are needed to ensure the safety of the vehicle during missions.

由于目前水下操作设备如深海浅地层岩芯取样钻机、电视抓斗等具有体积小、操作灵活等特点，而且要求设备能够在无人操作的前提下工作，因此需要声纳式高度计来保证设备能安全地在水下工作。
