When a platform or bench scale simply is not practical, hanging and crane scales offer a direct, reliable solution for weighing suspended loads. Whether you are weighing livestock in a farm environment, bulk freight at a logistics hub, or heavy equipment during a lifting operation, our range of hanging crane scales covers capacities from 15kg up to 12,000kg, with the precision and durability that industrial applications demand.

When to Use a Hanging or Crane Scale

Hanging scales and crane scales are the right choice in situations where placing a load on a platform is impractical, inefficient, or impossible. Common applications include:

• Warehouse and logistics: weighing pallets, bulk freight, and large containers suspended from overhead cranes or hoists
• Agriculture: weighing livestock, grain sacks, fertiliser loads, and feed deliveries
• Manufacturing: goods-in and goods-out control, checking weight during production or despatch
• Construction and maintenance: weighing materials, structural components, and equipment during lifting operations
• Waste and recycling: weighing skips, bulk material collections, and scrap by weight

The key advantage over floor-based platform scales is that the load is weighed as it is being moved rather than requiring a separate weighing step. For high-throughput operations, this saves significant time and reduces the risk of handling errors.

Hanging Scales vs Crane Scales

Both hanging scales and crane scales work on the same principle of suspending the load from a calibrated load cell. The practical distinction is in capacity and construction. Hanging scales tend to be lighter-duty instruments, typically suited to capacities from a few kilograms up to around 300kg. They are commonly used in agricultural, retail, and light industrial settings where portability and ease of use matter as much as raw capacity.

Crane scales are engineered for heavier-duty applications, starting from around 150kg and scaling up to 12,000kg in our range. They are designed to be permanently or semi-permanently integrated into overhead crane and hoist systems and are built to handle the dynamic loads that come with lifting and swinging. The housings are robustly constructed, the load cells rated for both static and dynamic loading, and many models include remote displays and data output options for integration into wider systems.

Do Hanging and Crane Scales Need to Be Trade Approved?

Trade approval is required if the weight reading directly determines the price in a commercial transaction. If you are purchasing scrap metal by weight, selling agricultural produce by weight, or charging customers based on the weight of a load, then yes, the scale used for that transaction needs to carry the M verification marking under the UK Non-Automatic Weighing Instruments (NAWI) regulations. If you are using hanging or crane scales purely for internal operational purposes, such as checking whether a load is within a crane's safe working limit, managing production batch weights, or monitoring stock movements, trade approval is not a legal requirement. GNW Instrumentation can advise on whether a specific model in our range carries trade approval, and calibration certificates are available for all products on request.

What to Look for in a Hanging or Crane Scale

Capacity and resolution. Match the maximum capacity to your heaviest expected load, with headroom to spare. The resolution (the smallest weight increment displayed) matters for accuracy. For livestock or bulk materials, a resolution of 0.5kg or 1kg is typically sufficient. For precision applications, a finer division is preferable.

Display and readability. All models in our range feature high-contrast LED or LCD displays with backlit options for use in poor lighting conditions. Look for tare and hold functions, which allow you to zero the scale with a hook or attachment in place, and freeze the reading once the load has stabilised.

Build quality and IP rating. For outdoor or agricultural use, check whether the scale has any weatherproofing. Many of our Kern and Adam Equipment crane scales feature robust metal housings with sealed electronics suitable for use in dusty or wet conditions.

Unit switching. Most models in the range offer conversion between kilograms and pounds as standard, with some supporting additional units. This is useful for operations that work with both metric and imperial specifications.

How Do You Calibrate a Hanging or Crane Scale?

Calibration of a hanging or crane scale involves applying a known reference weight and verifying that the scale's reading matches within the required tolerance. For simple portable hanging scales, this is often done with calibrated test weights placed in a sling or pan. For larger crane scales, calibration typically requires certified deadweight systems or calibrated load cells used as reference standards. GNW Instrumentation offers calibration services for all instrumentation we supply, with fast turnaround times and competitive pricing. If your scale is used for trade purposes, re-calibration and re-verification after any adjustment or repair is a legal requirement, not just best practice. UKAS-traceable calibration certificates are available on request to satisfy ISO 9001 and other quality management requirements.
