Product Description Features of general gantry crane:I. Structural features Sturdy metal structure General gantry cranes are usually made of high-quality steel such as Q235 and Q345. These steels have high strength and rigidity and can withstand large loads. The main girder generally adopts box structure or truss structure, with good bending and torsional resistance. The legs can be single-beam or double-beam type, which are selected according to different usage needs.The connection methods of the metal structure are mainly welding and bolt connection. Welded connections are firm and reliable and can ensure the integrity of the structure; bolt connections are convenient for disassembly and installation and are suitable for occasions that require frequent movement. Stable gantry structure The gantry is the main load-bearing structure of the general gantry crane and is composed of two legs and one main girder. The span of the gantry can be designed according to actual needs, generally ranging from several meters to dozens of meters. The legs are usually connected to the ground or foundation by rigid connection or flexible connection to ensure the stability of the crane during operation.The shape and size of the main girder will also affect the stability of the crane. Common main girder shapes include box type and truss type. Among them, the box-type main girder has better bending and torsional resistance and is suitable for cranes with larger spans.II. Working performance features Large lifting capacity and large lifting height The lifting capacity of general gantry cranes generally ranges from several tons to dozens of tons or even hundreds of tons, which can meet the loading and unloading and handling needs of different scales of goods. The lifting height can also be designed according to actual needs, generally ranging from several meters to dozens of meters, which can meet the loading and unloading operations of high-level goods.In order to achieve large lifting capacity and large lifting height, general gantry cranes are usually equipped with high-power lifting mechanisms and high-strength wire ropes. The lifting mechanism generally uses electric hoists or winches, with high lifting speed and accuracy. The diameter and strength of the wire rope will also be selected according to the lifting capacity and lifting height to ensure safety and reliability. Flexible working mode General gantry cranes can travel on tracks or move freely on the ground. Track-mounted cranes are suitable for fixed workplaces such as factories and warehouses; ground-mobile cranes are suitable for occasions that require frequent movement such as construction sites and port terminals.The lifting mechanism and traveling mechanism of the crane can be controlled separately or operated in linkage. This enables the crane to achieve multiple working modes during operation, such as hook lifting, grab grabbing, electromagnetic chuck adsorption, etc., to meet the loading and unloading needs of different goods. High working efficiency The lifting speed and traveling speed of general gantry cranes are relatively fast, and the loading and unloading and handling tasks of goods can be completed in a relatively short time. At the same time, the operation of the crane is relatively simple, and generally only one operator is required to complete all operations.In order to improve work efficiency, general gantry cranes can also be equipped with an automated control system to realize the automatic operation and remote control of the crane. The automated control system can improve the working accuracy and safety of the crane and reduce the labor intensity of operators.III. Safety performance features Complete safety protection devices General gantry cranes are equipped with a variety of safety protection devices such as limit switches, overload protection devices, and emergency stop buttons. Limit switches can limit the lifting height and traveling range of the crane to prevent collisions and derailment accidents of the crane; overload protection devices can automatically cut off the power supply when the lifting weight exceeds the rated value to protect the safety of the crane and goods; emergency stop buttons can quickly stop the operation of the crane in case of emergency to avoid accidents.In addition, the electrical system of the crane also adopts safety measures such as grounding protection and leakage protection to ensure the personal safety of operators. Strict qualiy control and inspection General gantry cranes are subject to strict quality control and inspection in accordance with national standards and industry specifications during the production process. From the procurement of raw materials to the processing and manufacturing of parts and components, and then to the assembly and commissioning of the whole machine, every link must undergo strict inspection and testing to ensure that the quality and performance of the crane meet the requirements.Before leaving the factory, the crane also needs to undergo load tests and dynamic load tests to verify whether the performance indicators such as lifting capacity, lifting height, and traveling speed of the crane meet the design requirements. At the same time, a comprehensive inspection of the safety protection devices of the crane is also required to ensure that they are reliable and effective.
