What Is a Crane Scale?
A crane scale, or hoist scale, is a lifting scale designed to measure the mass of an object suspended from a crane’s hook. It is particularly useful for items too large for a platform scale or that would roll off one. Crane scales feature lightweight displays for easy weight reading, and wireless models can transmit data to a PC or display measurements remotely.
Uses of Crane Scales
Crane scales are essential for weighing long or unstable items that are challenging to measure on a platform scale. They facilitate the weighing of goods during loading or transportation, enhancing work efficiency in the manufacturing sector by enabling the simultaneous weighing and documentation of product shipments. They are also used in agriculture and scrap metal industries for weighing and calculating monetary value.
Principle of Crane Scales
Crane scales offer the convenience of mobility, allowing for the weighing of items in various locations, even on uneven or unstable surfaces. While more compact and portable than platform scales, they may be less accurate due to external factors like wind or movement. Safety precautions are necessary to ensure the crane or support structure can handle the weight without risk of accidents.
How to Choose a Crane Scale
1. Weight Range of the Cargo
Select a crane scale with a maximum capacity exceeding the weight of the cargo to be measured to prevent overload and potential accidents.
2. Resolution and Accuracy
For applications requiring precise measurements, choose a crane scale with high resolution and accuracy, especially where quality control or safety is critical.
3. Environmental Conditions and Durability
Consider the environmental conditions where the scale will be used, such as indoor or outdoor settings and temperature extremes. Durability ensures the scale’s longevity and reliability over time.
4. Interfaces and Data Management
Ensure the crane scale meets your data management needs, with features like digital display, data logging, and communication capabilities for PC integration and data storage.
