Seamless docking skills between single-beam bridge crane and ground forklift

The seamless docking between single-beam bridge cranes and ground forklifts requires the implementation of four core skills: operational coordination, spatial planning, equipment adaptation, and safety control. By combining standardized processes with real-time communication, operational efficiency can be significantly improved and risks can be reduced. The following are specific skills and implementation points:

1. Operational coordination skills: precise control of movements

Synchronous lifting and translation

Crane operation: When lifting goods above the forklift, variable frequency speed regulation technology is used to control the lifting speed (adjustable from 0.5 to 1.5 meters per minute) to avoid cargo swaying. At the same time, a dual-speed motor is used to achieve rapid switching of the translation speed (e.g., slow speed for precise positioning and fast speed for long-distance movement).

Forklift operation: The forklift driver needs to adjust the height and angle of the forks in advance according to the position of the crane hook. For example, when the hook descends to a distance of 0.5 meters from the forks, the forklift slowly moves forward to the exact position beneath the cargo, ensuring that the forks align with the bottom of the cargo.

Micro-motion control

The crane operator achieves millimeter-level movement of the cargo through small adjustments with the joystick, reducing the time spent on repeated adjustments. The forklift driver, on the other hand, controls the driving speed using a micro-adjustment pedal to ensure precise positioning beneath the cargo.

II. Spatial planning techniques: optimizing operational paths

Division of work areas

Plan the operating areas for cranes and forklifts in advance to avoid cross interference. For example, maintain a safe distance of at least 2 meters between the crane's operating track and the forklift's driving route, and set up marking lines on the ground.

Utilization of three-dimensional space

Utilizing the space beneath the crane bridge, the cargo can be vertically lowered to above the forks of the forklift by adjusting the height and angle of the hook, thereby reducing the horizontal movement distance. The forklift then selects the optimal stopping point based on the size of the cargo, such as using the "diagonal entry" method to shorten the docking time.

III. Device adaptation skills: matching performance parameters

Matching of lifting sling and fork

Select the appropriate lifting device (such as electromagnetic suction cups, grab buckets, or specialized lifting hooks) based on the type of cargo (such as boxes, pipes, or irregular-shaped items), and ensure that the lifting device is compatible with the dimensions of the forklift's forks. For example, use a forklift with adjustable forks to accommodate the lifting of cargo with different widths.

Load capacity coordination

Ensure that the rated lifting capacity of the crane matches the rated load of the forklift. For example, if the rated lifting capacity of the crane is 5 tons, the rated load of the forklift should not be less than 4 tons to avoid the risk of overload.
