What is the difference between a beam crane and an overhead crane?

Girder type crane beam crane mainly includes single girder overhead crane and double girder overhead crane, and the main beam of the single girder overhead crane bridge is mostly made of I-shaped steel or a combined section of steel type and steel plate. The hoisting trolley is often assembled by chain hoist, electric hoist or hoist as a hoist mechanism. According to the bridge support type and suspension type.

The former bridge runs along the crane track on the car girder; The bridge of the latter runs along a crane track suspended under the truss of the factory building. There are two types of single girder overhead cranes: manual and electric. The working speed of each mechanism of the manual single girder overhead crane is low, and the lifting capacity is also small, but its own quality is small, which is convenient for organizing production and low cost.

The manual single girder overhead crane adopts a manual monorail trolley as the running trolley, a chain block as the lifting mechanism, and the bridge frame is composed of a main beam and an end beam. The main beam is generally made of single I-beam. The working speed and productivity of the electric single girder overhead crane are higher than those of the manual one, and the lifting capacity is also larger.

The electric single girder overhead crane is composed of a bridge frame, a cart running mechanism, an electric hoist and electrical equipment. Overhead crane: Overhead crane is a kind of bridge crane that runs on an elevated track, also known as a crane crane.

The bridge frame of the overhead crane runs longitudinally along the track laid on the elevated on both sides, and the lifting trolley runs transversely along the track laid on the bridge frame, forming a rectangular working range, and the space under the bridge can be fully utilized to lift materials, and is not hindered by ground equipment. Ordinary overhead cranes are generally composed of a lifting trolley, a bridge running mechanism, and a bridge metal structure. The hoisting trolley is composed of three parts: the hoisting mechanism, the trolley running mechanism and the trolley frame.

The lifting mechanism includes an electric motor, a brake, a reducer, a drum and a pulley block. The motor drives the drum to rotate through the reducer, so that the wire rope is wound on the drum or lowered from the drum to lift heavy objects. The trolley frame is a frame that supports and installs components such as the lifting mechanism and the trolley running mechanism, which is usually a welded structure.

The similarities and differences between overhead cranes and gantry cranes are not only different in appearance, but also in different roles. Their similarities and differences are as follows: Difference 1:

Overhead crane is a lifting equipment that lifts materials across the top of workshops, warehouses and stockyards. 2.Gantry crane is a deformation of overhead crane, also known as gantry crane.

It is mainly used for the loading and unloading of outdoor freight yards, material yards and bulk cargo. Difference 2: The shape of the overhead crane resembles a bridge because its two ends are located on tall cement pillars or metal supports.

2.The gantry crane metal structure is like a door-shaped frame, and two feet are installed under the bearing main beam, which can walk directly on the track on the ground, and the two ends of the main beam can have overhanging cantilever beams. Difference three:

The bridge frame of the overhead crane runs longitudinally along the track laid on the elevated on both sides, which can make full use of the space under the bridge to lift materials without being hindered by ground equipment. It is a kind of lifting machinery with the widest range of use and the largest quantity. 2.

Gantry cranes have the characteristics of high site utilization, large operating range, wide adaptability and strong versatility, and are widely used in port freight yards. Difference 4: The appearance is different.

1.Overhead crane 2Gantry crane.

First, the nature is different.

1. Beam crane: It is a kind of crane, which is a crane composed of a bridge frame and a lifting trolley.

2. Overhead crane: It is a lifting equipment that is cross-framed over the workshop, warehouse and material yard for material lifting.

Second, the structure is different.

1. Beam crane: there are three working mechanisms: lifting, bridge walking, and trolley walking. Powered by human or electric power. It is mostly used to handle goods in factories or workshops.

2. Overhead crane: The bridge of the overhead crane runs longitudinally along the track laid on the elevated on both sides, and the lifting trolley runs horizontally along the track laid on the bridge, forming a rectangular working range, which can make full use of the space under the bridge to lift materials without being hindered by ground equipment.

Third, the application is different.

1. Beam crane: used for lifting goods in factories, warehouses, material yards and other different occasions, and it is forbidden to use it in flammable, explosive and corrosive media environments.

2. Overhead crane: This kind of crane is widely used in indoor and outdoor warehouses, workshops, wharves and open-air storage yards.

Summary. Hello! The girder of an overhead crane (also known as a girder, bridge, girder bridge) refers to the main load-bearing component of an overhead crane, which usually presents a box-shaped or beam-shaped structure.

The girder is a beam suspended from a pillar to support the various equipment of the crane, such as a winch, a walking machine, a lifting mechanism, etc. Girders are usually made of steel, which has characteristics such as high strength, high rigidity, and lightness to withstand the working load of the crane. The length and height of the girder are usually designed according to the use of the crane and the requirements of the workplace, and different structural forms such as single girder, double girder, box girder, etc. can be adopted.

Girder is one of the most important components of the overhead crane, which is directly related to the working efficiency and safety of the crane

Hello! The girder of an overhead crane (also known as a girder, bridge, girder bridge) refers to the main load-bearing component of an overhead crane, which usually presents a box-shaped or beam-shaped structure.

Chongming girders are usually made of steel, which has the characteristics of high strength, high rigidity, and lightness to withstand the working load of the crane. The length and height of the girder are usually designed according to the use of the crane and the requirements of the workplace, and different structural forms such as single girder, double girder, box-shaped non-segment beam can be adopted. Girder is one of the most important components of the overhead crane, which is directly related to the working efficiency and safety of the crane

Qinqin also learned that when operating the girder of the overhead crane, the following points should be noted:1Safety first:

Operators should strictly abide by the operating procedures and wear safety protective equipment to ensure their own safety. 2.Check the girders:

Before operation, the structure and connectors of the girder should be carefully inspected to ensure that there are no cracks, sublease and shape or other damage to the girder. 3.Check the loadout:

When installing or removing the load, carefully check whether the weight and size of the load meet the bearing capacity of the girder, and strictly follow the operating procedures. 4.Reasonable disadvantages to distribute the load:

When using the crane, the load should be distributed reasonably to avoid excessive or unbalanced load, which will cause the girder to deform or not be able to bear the working load. 5.Risk Prevention:

When operating the crane, you should pay attention to the surrounding environment and meteorological conditions to prevent risks. For example, when the wind is too strong, the crane should be stopped to avoid damage or overturning of the girders. 6.

Regular inspection and maintenance: Regular inspection and maintenance of the girders, such as cleaning, painting, replacing the bolt shed cavity, checking the electrical system, etc., can prolong the service life of the girders and ensure the safety and stability of the crane. When operating the girder of the overhead crane, you should pay attention to safety, check the girder and load, reasonably distribute the load, prevent risks, and regularly inspect and maintain the problems
