As a leader in the field of heavy equipment manufacturing, the design and calculation instructions of the 120T gantry crane are the key to ensuring the safe and efficient operation of the equipment. The instructions not only cover the main performance parameters of the crane, such as rated lifting capacity, lifting height, travel distance and operating speed, but also deeply analyze the structural composition and design details of the crane. From the precise coordination of the crane and the traveling assembly, to the stable support of the legs and bracket assembly, to the ingenious design of the main beam assembly and the beam shoulder pole, each one reflects the engineers' deep understanding of mechanics and mechanical principles. In addition, the instructions also elaborate on the core elements of the crane design, including the selection of the lifting mechanism, the motor configuration of the operating mechanism, the calculation of the reducer and gear ratio, etc., presenting a comprehensive and systematic design solution to readers.

Detailed description of the main performance parameters of the craneRated lifting capacity and lifting height

As a heavy lifting equipment, the core performance of the 120T gantry crane is reflected in the rated lifting capacity and lifting height. The crane is designed with a rated lifting capacity of 120 tons, which means that under normal working conditions, it can safely lift and carry cargo weighing no more than 120 tons. This parameter is crucial to ensure safe and efficient operation. The lifting height is the vertical distance from the center line of the crane hook to the ground. For different operation scenarios, the required lifting height is also different. The lifting height of this crane is designed to meet the needs of different operation scenarios, ensuring that the goods can be lifted and lowered to the specified position smoothly and accurately.

Trolley travel distance and whole machine running speed

The trolley travel distance refers to the maximum distance that the crane moves horizontally on the track. This parameter directly affects the working range and flexibility of the crane. For 120T gantry cranes, the trolley travel distance is carefully designed to meet a wide range of operation needs. The whole machine running speed is an important indicator to measure the working efficiency of the crane. The crane achieves a faster whole machine running speed while ensuring safety, which improves the operating efficiency. At the same time, the crane also has excellent whole machine running stability, ensuring that there will be no shaking or instability during high-speed operation.

Beam crane running speed and lifting speed

The beam crane is an important part of the crane, and its running speed directly affects the handling efficiency of the goods. The running speed of the beam crane of the 120T gantry crane has been optimized to move the goods quickly and smoothly while ensuring safety. This feature enables the crane to better meet various emergency or high-efficiency operation requirements. The lifting speed is the speed of the hook lifting and lowering. The lifting speed of the crane is reasonably designed and can be flexibly adjusted according to the weight of the cargo and the operation requirements. Whether it is light cargo or heavy cargo, the crane can achieve fast and accurate lifting operations.

Crane performance parameter relationship diagramAdaptability to slope and running track foundation

In order to adapt to different terrains and working environments, the 120T gantry crane was designed with its adaptability to slopes in mind. Within a reasonable slope range, the crane can maintain stable operation. This feature enables the crane to better adapt to various complex working environments. At the same time, the running track foundation is also a key factor in ensuring the safe and stable operation of the crane. The running track foundation of the crane is designed to be sturdy and can withstand the huge pressure and vibration generated by the crane during operation. Whether it is indoor or outdoor operation, the crane can maintain a good operating state.

Crane structure composition and designBeam crane and running assembly structure

As the core working component of the crane, the main function of the beam crane is to undertake the lifting, lowering and horizontal movement of goods. It consists of a beam, a crane motor, a reducer, a drive wheel, a guide wheel, a wire rope and a pulley block. The hanging beam usually adopts a box-shaped or truss structure, which has sufficient strength and rigidity to withstand the pressure and bending moment caused by the weight of the cargo; the driving motor provides power, transmits power through the reducer, drives the driving wheel to rotate, so that the hanging beam can run smoothly and quickly on the track; the running assembly is an important mechanism for the crane to move on the track. It consists of components such as wheels, bearings, shafts, tracks and guide devices. The wheels bear all or most of the weight of the crane and roll on the track, allowing the crane to move easily on the track; the bearings play a role in reducing friction and improving the flexibility of wheel rotation; the shafts are used to connect the wheels and bearings and transfer loads; the track is the track of the crane's operation, usually fixed on the building or the ground, providing a stable operating foundation for the crane; the guide device ensures that the crane maintains the correct direction and position during operation.

Outrigger and bracket assembly structure

The outrigger is an important supporting component of the crane. Its structural design must ensure that the crane can stably carry the weight of the cargo and additional loads during operation, while maintaining good anti-overturning performance. When designing the outrigger, factors such as the overall layout of the crane, the working radius, and the stability requirements need to be considered. The outriggers are usually designed with a box-shaped or H-shaped cross section, which has sufficient strength and rigidity to withstand the pressure and shear force caused by the weight of the cargo; the bracket assembly is used to connect the outriggers and the main beam. Its structural design needs to ensure the overall stability of the crane and facilitate installation and maintenance. The bracket assembly usually includes connecting plates, reinforcing ribs, mounting seats and other components.

Design of main beam assembly and hanging beam shoulder pole

As the main load-bearing component of the crane, the main beam connects the outriggers and the hanging beam crane. Its design directly affects the overall rigidity and stability of the crane. When designing the main beam, factors such as its load-bearing capacity, deformation and vibration need to be considered. The main beam usually adopts a box-shaped or truss structure, which has sufficient strength and rigidity to withstand the pressure and bending moment caused by the weight of the cargo; the hanging beam shoulder pole is a key component connecting the hanging beam and the cargo, and its design needs to take into account the weight, shape and handling requirements of the cargo. The shoulder pole usually adopts a box-shaped or circular cross-section design, which has sufficient strength and rigidity to withstand the pressure and shear force caused by the weight of the cargo. At the same time, the installation position and angle of the shoulder pole also need to be considered to ensure the stability and safety of the goods during handling.
