When choosing a portal crane, there are many technical parameters that need to be carefully considered to ensure that the equipment can meet the actual use needs.
The first is the lifting capacity. The lifting capacity is one of the most important parameters of the portal crane, which determines the maximum weight of the cargo that the crane can handle. When determining the lifting capacity, it is necessary to consider the maximum load that may be encountered in actual work and leave a certain safety margin. At the same time, factors such as the shape, size and center of gravity position of the cargo should also be considered to ensure the stability of the crane during the lifting process.
The second is the span. The span refers to the distance between the two legs of the portal crane. The choice of span should be determined according to the actual situation of the site of use, ensuring that the crane can move freely in the working area and will not collide with surrounding buildings or equipment. For larger working areas, a crane with a larger span can be selected, but the structural strength and stability of the crane also need to be considered.
The lifting height is also a key parameter. The lifting height refers to the maximum height to which the crane can lift the cargo. When choosing the lifting height, it is necessary to consider the height limit of the work site and the stacking height requirements of the cargo. If the lifting height is insufficient, it may result in the inability to complete certain work tasks.
The running speed is also a factor that needs to be considered. Including the running speed of the trolley and the running speed of the trolley. The choice of running speed should be determined according to the requirements of work efficiency. Faster running speed can improve work efficiency, but safety and stability also need to be considered. At the same time, the stability of the crane during starting, braking and speed change should also be considered.
In addition, the working level of the crane is also very important. The working level reflects the frequency of use and load status of the crane. Different working levels correspond to different design requirements and service life. When selecting a crane, the appropriate working level should be selected according to the actual working conditions to ensure the reliability and durability of the crane.
The performance of the electrical system should not be ignored. Including the power of the motor, control method, safety protection device, etc. A good electrical system can ensure the stable operation and safe operation of the crane.
Finally, the convenience of crane maintenance and maintenance needs to be considered. Choosing a crane with a simple structure and easy maintenance can reduce the subsequent maintenance cost and downtime.
In summary, when choosing a portal crane, you need to consider technical parameters such as lifting capacity, span, lifting height, operating speed, working level, electrical system performance and maintenance convenience to ensure that you choose the crane equipment that best meets your actual needs.
