Analysis Of Working Principle Of Gantry Crane

     Working principle of truck Crane: The crane is a kind of crane installed on the chassis of ordinary automobile or special vehicle, and its driving cab is set separately from lifting control room. The advantages of this kind of crane are good maneuverability and rapid transfer. The disadvantage is that the work must be supported by legs, can not be loaded, and is not suitable for soft or muddy ground work.Gantry Crane

     The chassis performance of the truck crane is equivalent to that of the truck with the same total weight, which conforms to the technical requirements of the road vehicle, so it can be unobstructed on all kinds of highways. This type of crane is generally equipped with up to two control rooms, the operation must be extended leg to maintain stability. The starting weight range is large, from 8 ton ~1000 ton, chassis axle number, can from $number root. is the largest and most widely used crane type.Gantry Crane

     Working principle: Under the boom inside there is a rotating reel, above the wire rope, wire rope through the next section of the arm on the top of the pulley, pull out the last section of the lifting arm, and so on. When retracted, the reel is reversed to reclaim the wire rope, and the lifting arm is retracted in the next time. This rotating reel is driven by a hydraulic motor, so you can see two tubing, but don't use it as an oil cylinder. In addition, there are some car crane telescopic arms fitted with a set of plunger-type cylinder, but this application is very rare. Because of the high cost of multistage plunger type cylinder, and the elastic bending occurs when the boom is loaded, it has great effect on the life of the oil cylinder.Gantry Crane

    The device used to carry iron and steel material by electromagnet is called an electromagnetic crane. Electromagnetic crane can produce a strong magnetic force, dozens of tons of iron pieces, iron wire, nails, scrap iron and other kinds of ferrous materials, not packing does not need to be bundled, can be easily collected and transported, not only the operation of labor-saving, but also simplified work. Steel materials and machines fitted in wooden cases can be transported equally. Cranes work, as long as the electromagnetic iron coil in the current non-stop, the heavy lifting will not fall, invisible magnetic force than a solid chain more reliable. Gantry Crane

    If the electricity is broken for some reason, it will cause an accident, so some of the electromagnetic cranes are fitted with steel claws and the sturdy steel claws will automatically fall down to hold them tightly after lifting the heavy weights. Cranes cannot carry hot iron blocks because high temperature steel cannot be magnetized.Gantry Crane
