Lifting Scales & Weighing Systems

Scales & Weighing Systems for Crane Lifting

As technology has improved every lifting manager now has the possibility of instantly knowing what weight their lifting equipment is actually bearing at any given time thanks to integrated and detachable crane scales / weighing systems.

The price of these advanced systems are continually becoming more and more affordable and popular. Many of the new crane systems that Granada manufacture now incorporate integrated digital load weighing systems. Not only can these crane scales systems be integrated into bespoke new Crane designs, They can also be retro-fitted to any existing lifting equipment, Many customers have found this to be an ideal way of modernising existing infrastructure.

Installation Options

Integrated Crane Scales / Digital Load Weighing

Integrated crane scales and weighing systems transmit real-time digital load data to a multitude of output and analysis devices, Including Large LED displays that can be mounted on the crane, Operator handheld displays, Computer event recording software and direct printer connections. Not only can these be incorporated into new bridge crane designs but can also be retrofitted to existing overhead cranes and lifting equipment.

Crane Scales Integrated into new designs

When integrating load-weighing functionality into new crane designs Granada uses Baron’s advanced digital weighing systems. Barons weighing system is a professional solution that allows you to weigh loaded material immediately during the lifting phase. It transmits via a wireless connection to digital repeaters with digits up to 160 mm in size and can send data directly to printers and computer software for data analysis and recording.

Crane Scales Retro-fitted to existing cranes

Using Tractel’s DYNASAFE range of sensors and displays, Granada can fit integrated crane scales/load weighing systems onto any existing crane. From a visual display of the current load being lifted to intelligent overload monitoring and prevention, integrated crane scale systems are a great way to modernise existing lifting equipment.

Tractels DYNASAFE Range includes:

Load display and digital force management monitor system.
Dead-end load cells

Benefits & Use Cases

These varied benefits and use cases underline the significance of integrated crane scales and weighing systems in modern lifting operations. As Granada Cranes continues to innovate in this space, many businesses will find immeasurable value, both in safety and operational efficiency, by incorporating these advanced systems.

Ensuring Load Safety

By instantly providing the weight of a lifted object, crane scales prevent the dangerous and costly overloading of lifting equipment. Managers can ensure they’re within safe weight limits and avoid potential equipment damage or catastrophic failures.

Streamlining Shipping and Logistics

For businesses involved in shipping and transport, knowing the exact weight of goods is crucial. Integrated weighing systems on cranes allow for precise cargo measurements, ensuring that freight weights match the documentation, thus avoiding potential shipping penalties or discrepancies.

Optimising Storage Space

In warehousing, where space is at a premium, knowing the weight of items can help in efficient storage planning. Heavy items can be appropriately stored, ensuring safety and optimal space utilization.

Reducing Manual Weighing Processes

Before the advent of integrated crane scales, loads often needed to be weighed separately. With integrated and detachable crane scales, this additional step is eliminated, saving time and reducing operational steps.

Regulatory Compliance

Certain industries have strict weight regulations. Whether it’s for safety, shipping, or trade, knowing the exact weight can help businesses adhere to regional and international standards, thus avoiding legal implications or fines.

Enhancing Equipment Longevity

By avoiding inadvertent overloading, the longevity of the crane and its associated systems can be prolonged. Regular overloads, even small ones, can cause wear and tear over time. Knowing the weight helps in preserving the equipment’s operational life.

Real-time Inventory Management

Especially relevant for businesses that deal in bulk materials, integrated weighing systems allow for real-time inventory updates. As materials are loaded or unloaded, the system can update the stock levels, aiding in efficient inventory management.

Cost-Efficiency for Older Infrastructure

For companies with older crane systems, retrofitting with modern scales and weighing systems can be a cost-effective way to enhance their equipment’s capabilities without investing in entirely new machinery.
