Classification of Bridge CranesThere are many types of bridge cranes, which can be classified according to different methods.1) According to different lifting devices, they can be divided into hook type cranes, grab bucket cranes, and electromagnetic suction cup cranes.2) According to different purposes, it can be divided into two categories: general bridge cranes and specialized bridge cranes. There are various forms of specialized bridge cranes, including forged bridge cranes, cast bridge cranes, metallurgical bridge cranes, power station bridge cranes, explosion-proof bridge cranes, insulated bridge cranes, hanging beam bridge cranes, dual-purpose (three purpose) bridge cranes, and high lifting height bridge cranes.2. The purpose of bridge craneBridge cranes are widely used in various industrial enterprises, ports, warehouses, material yards, power stations, and other places.Different types of bridge cranes are suitable for lifting different heavy objects, and different lifting devices are used according to different requirements. Hook crane lifts various heavy components; The grab crane lifts various bulk items such as coal, coke, sand, salt, etc; Electromagnetic cranes are used to lift magnetic materials such as steel sections, steel plates, scrap steel, etc.A dual-purpose or triple purpose crane is designed to improve production efficiency by installing a convertible hook, grab bucket, or electromagnetic disc on a small car. It can lift individual pieces, loose particles, or magnetic metal materials, but only one of the lifting devices can be used each time a heavy object is lifted.Explosion proof cranes are used to lift heavy objects in workshops, warehouses, and other places with flammable and explosive media. The electrical equipment and related devices on the crane have explosion-proof characteristics to prevent sparks from causing explosions. Insulated cranes are used to lift various components in the electrolysis workshop. The relevant parts of the crane are equipped with reliable insulation devices to ensure safe operation.A double trolley crane is equipped with two trolleys on the same main beam, which can work together or be used separately.The hanging beam crane lifts and stacks various long materials, such as wood, steel pipes, rods, profiles, steel plates, etc., through the balance beam hooks on two hooks or the electromagnetic disk on the balance beam.

The LH type electric hoist bridge crane is a double beam structure crane that is used in conjunction with fixed electric hoists such as CDI and MDI. The trolley runs on the track laid on the main beam, and the double main beam structure bridge crane is suitable for lifting weights of 1-50t, spans of 7.5-31.5m, and working environment temperatures ranging from -25 to+40 ℃. It has the characteristics of compact external structure, low building clearance height, light weight, and low wheel pressure, and is suitable for transportation, assembly, maintenance, and loading and unloading operations in mechanical processing workshops, metallurgical plant auxiliary workshops, warehouses, material yards, and power stations.

The device that uses electromagnets to transport steel materials in a double beam crane is called an electromagnetic crane. The main component of an electromagnetic crane is the electromagnet. By connecting the current, the electromagnet firmly attracts the steel object and lifts it to the designated location. Cut off the current, the magnetism disappears, and the steel object is put down. Electromagnetic cranes are very convenient to use, but they must have current to be used, and can be applied in waste steel recycling departments and steelmaking workshops.

QD type electric double beam bridge crane is a common lifting equipment widely used in factories, warehouses, docks, shipyards and other places. It has the characteristics of simple structure, easy operation, safety and reliability, and is an indispensable important equipment in modern industrial production.The QD type universal bridge crane relies on longitudinal movement along the supporting track direction of the factory crane beam, lateral movement of the trolley, and lifting and lowering of the hook to achieve the workflow. The commonly used lifting capacity is 5-200t (larger lifting capacity can be customized), the working level is A5-A7, and the working environment temperature is -25 ℃~40 ℃. It is prohibited to use it in flammable, explosive, and corrosive media environments. There are three types of control modes for users to choose from: ground control, control room control, and remote controlThe main components of QD type electric double beam bridge crane include bridge frame, lifting machinery, electrical system, etc. The bridge is composed of two beams, which are connected by crossbeams to form a bridge shaped structure. Lifting machinery includes cranes, large vehicles, small vehicles, etc. They can move freely on beams to achieve functions such as lifting and transporting objects. The electrical system includes motors, controllers, cables, etc., which control the operation and stop of the crane, ensuring its safety and stability.

The double beam bridge grab crane is a special type of crane that uses a grab bucket as a lifting device. It mainly consists of a box shaped bridge, a grab bucket trolley, a large vehicle operating mechanism, a driver's cab, and an electrical control system. The retrieval device is a grab bucket, which can complete various special tasks such as loading, unloading, stacking, and transportation. Capable of handling heavier loads up to 20 tons, it is suitable for lifting and transporting bulk materials such as grain, ore, quartz powder, limestone, nickel, scrap metal, waste materials, blocks, coal, sand, other granular materials, and wood in warehouses and workshops of cement and coal yards. It is widely used in steel plants, garbage treatment plants, mines, ports, railways, and power plants. The grab crane has high requirements for high temperature, dust, and corrosive environments. We can provide grab cranes for your application.

Casting crane is the main equipment in steelmaking and continuous casting process, mainly used for lifting and transporting liquid steel ladles.From the overall structure, it can be divided into: double beam double track, four beam four track, and four beam six track. The first two types are generally used for medium and large tonnage casting cranes, while the third type is generally used for extra large tonnage casting cranes.
