When a single beam crane is in operation, its speed needs to be adjusted according to the usage requirements. How to adjust the speed of a single beam crane?

1. For jobs that require frequent work or high productivity, the working speed of the organization often adopts high speed; For single beam suspension cranes used on production lines or even engaged in rhythmic continuous production, their working speed should be adapted to the rhythm of production; For non working mechanisms or mechanisms that only perform adjustment work and operate infrequently, low speed is generally used. The single beam crane has two operating modes: ground and aerial. There are two types of ground operations: wired handle operation and remote control handle operation; Aerial operation refers to the operation in the driver's cabin. There are two types of driver's cab: open and closed, which can be installed on the left or right side according to the actual situation. The entrance direction has two types: side and end, to meet the needs of users in various situations.

2. Medium speed is used for general purpose single beam suspension bridge cranes, high-speed is used for bulk material loading and unloading, and low-speed or micro speed is used for assembly and maintenance installation; Some crane mechanisms adopt speed regulation schemes to achieve full power utilization and improve productivity, using low speed for full load and heavy load, and high speed for empty load and light load.

3. High speed is used for small and medium lifting capacity, and low speed is used for large lifting capacity. Especially when there are two lifting mechanisms, the speed of the main lifting mechanism is generally significantly lower than that of the auxiliary lifting mechanism.

4. A single beam bridge crane with a large working stroke should use a higher speed, while one with a small working stroke is often used at a lower speed. The principle is to ensure that the mechanism has a working section that runs at a stable speed, avoiding the frequent situation of immediately entering deceleration operation before the acceleration ends, which is always in unstable operation. The single beam crane has two operating modes: ground and aerial. There are two types of ground operations: wired handle operation and remote control handle operation; Aerial operation refers to the operation in the driver's cabin. There are two types of driver's cab: open and closed, which can be installed on the left or right side according to the actual situation. The entrance direction has two types: side and end, to meet the needs of users in various situations.

5. The comprehensive balance effect, especially for single beam suspension bridge cranes with certain periodicity in operation, should be comprehensively considered when determining the working cycle diagram, including the lifting mechanism and translation mechanism. Firstly, the possibility of both mechanisms acting simultaneously should be fully utilized
