Gantry cranes are widely used in various industries of the national economy such as metallurgy, electric power, ports, logistics, machinery manufacturing and marine engineering. They are important process equipment for industrial production and are related to the safety of people's lives and the safety of national economic operations. and social stability are important components of public security in all countries. The development momentum of my country's hoisting machinery industry is strong. As of the end of 2017, the number of hoisting machinery in my country reached 2.2375 million units. According to the "Notice of the State Administration for Market Regulation on the Safety Status of National Special Equipment in 2017", the accident rate and fatality rate of cranes in my country rank first among the eight categories of special equipment.

Regarding the operating procedures for shipyard cranes, in fact, many employees must undergo relevant training before taking up the job. We cannot ignore any details. Now let's look at the specific requirements of the operating procedures.

Performance of shipyard crane: driving speed is lower than that of car type, higher than rail type, small turning radius, good off-road performance, uphill ability of 17% to 20%; tire gantry crane usually uses outriggers to lift weight, on flat ground You can work on all sides on the ground without using the outriggers, or you can walk slowly with a heavy weight on it. The stability performance is better.

The traditional wire rope flaw detection of port cranes has various disadvantages. The traditional hand-touching and visual inspection of calipers has various disadvantages. At present, weak magnetic wire rope flaw detectors have received more and more attention from customers. There are two types of weak magnetic flaw detection equipment for tire-type container gantry cranes. , a type of simple portable wire rope flaw detection machine, and another type of online flaw detection equipment for wire ropes fixed on the crane.
