What are the techniques for improving the efficiency of bridge cranes? For specific technical issues, let me take you to understand them together.
The improvement of operational efficiency for bridge cranes can be approached from four core dimensions: operation optimization, equipment maintenance, process management, and personnel collaboration. By combining specific operational skills and equipment characteristics, a dual improvement of safety and efficiency can be achieved. Here are specific techniques and analysis:
1、 Operation optimization: Accurate control, reducing ineffective actions
Stable hook operation
Principle: The swing of the hook is caused by horizontal force (large vehicle) or vertical force (small vehicle), which is counteracted by reverse following the vehicle to eliminate the swing.
skill:
When swinging horizontally, use the large car to stabilize the hook, when swinging vertically, use the small car to stabilize the hook, and when swinging diagonally, both the large and small cars need to be operated simultaneously.
The following distance is proportional to the swing amplitude of the hook head (a larger swing amplitude results in a larger following distance), ensuring that the hook stops smoothly at the designated position.
Effect: Reduce hook swing time, improve positioning accuracy, and avoid repeated adjustments.
Reasonably plan the lifting route
skill:
Survey the work area in advance, avoid obstacles, and choose short paths.
For high-frequency lifting tasks (such as material transportation on production lines), fix the route and mark it.
Effect: Shorten the single lifting time and increase the number of operations per unit time.
Accurately control lifting and lowering
skill:
Slowly accelerate during lifting to avoid sudden impact when the load leaves the ground; Reduce speed in advance during descent to prevent the load from falling rapidly.
Use the fine adjustment function of the remote control or joystick to achieve millimeter level positioning.
Effect: Reduce load shaking, lower equipment wear, and enhance operational safety.
2、 Equipment maintenance: ensuring performance and reducing downtime due to malfunctions
Regular lubrication and fastening
skill:
Regularly lubricate the steel wire rope, bearings, gears, and other parts according to the maintenance manual (such as applying special grease every week).
Check if the bolts, pins, and other connecting components are loose and tighten them in a timely manner.
Effect: Reduce frictional resistance, prolong equipment life, and minimize downtime caused by jamming.
Timely replace worn parts
Key components:
Wire rope: Replace immediately when the wire breakage rate exceeds 10% or the wear reaches 7% of the original diameter.
Brake pad: Replace when the wear exceeds 50% of the original thickness to ensure sensitive braking.
Effect: Avoid sudden component failures and ensure the continuity of operations.
Clean the track and work environment
skill:
Clean the oil and debris on the track daily to prevent the obstruction of large vehicles.
Maintain sufficient lighting in the work area (≥ 50lux) to reduce blind spots during operations.
Effect: Improve the stability of equipment operation and reduce human operational errors.
