Products are supplied with the express understanding that the purchaser and/or the user are thoroughly familiar with their correct application and proper use.
RON Crane Scales will assume no responsibility for the misuse or misapplication of any of its products.

In addition to these guidelines, the user must also comply with general safe operating practice, and when using the systems for weighing during lifting, the user must also comply with safe operating practice during lifting.

The load limit rating (or "capacity") indicates the maximum force or load a system can carry under normal working conditions. Overloading, or placing a load on the system above its rated capacity is dangerous and is therefore STRICTLY PROHIBITED, except during annual safety testing of the system, to be performed by qualified personnel, when overload of up to 25% of rated capacity is permitted.

RON Crane Scales will accept no liability for damage caused by the product being used in excess of the working load limit (capacity of the system) or from abuse.

Opening or attempting to open the systems and, needless to say, any attempt to repair the systems by unauthorised personnel (without written authorisation) will nullify the warranty as well as the manufacturer's liability, and could be dangerous.

When measuring loads using shifted zero or tare, the actual loading is the indicated value (the readout) plus the value of the shifted zero or tare.

The system is designed for occasional, not continuous, use. If the system is to be integrated with equipment that performs continuous loading over extensive periods of time, then use of a system with at least 30% higher rated capacity (load limit) is necessary. For example: a 3t crane should be used with a 5t load system.

The system is designed for static loading. RON Crane Scales or other qualified engineering personnel should be consulted before using the system to measure dynamic loads.

Avoid bending, side loading and off-axis loading.

When connecting the load cell in order to measure forces or loads, special care should be taken to choose the right connecting accessories that will permit free movement and prevent bending moments in the load cell.

Use shackles with S.W.L. (Safe Working Load) equal to, or greater than the system's maximum capacity.

Check the system thoroughly before use, including the lifting accessories which are included in some of the RON Crane Scales systems. Do not use a damaged system.

We recommend that the systems be checked occasionally by lifting a known weight.

We recommend that the systems be sent back to the manufacturer for general examination once every year.

Do not use the system with an unknown load if there is any doubt as to the reliability of the load indication. To check its reliability, use only a known load with a value of more than 50% and less than 100% of the system's rated capacity (load limit).

The permitted temperature range appears in the RON Crane Scales systems specification.
Do not allow the systems to overheat. This could be dangerous.

Take particular care not to expose the system to nuclear radiation.
Local environmental conditions such as extreme temperatures, radio transmissions or other magnetic radiation may interfere with reliable system operation and may cause a false (low) reading which could prove dangerous. Avoid using the system under such conditions.
The system is not explosion-proof and should not be used in hazardous areas.

S ystem calibration should be performed annually, in an authorized laboratory, unless laws, regulations, or other policies specify other intervals for calibration.

Between calibrations, the user can verify whether the systems are still calibrated correctly by using a known weight.

Calibration verification and adjustment must be performed with extreme care since a wrong calibration adjustment will result in false readings, which could be dangerous.

Unless otherwise specified, RON Crane Scales products are not legal for trade.

Each system consists of a load cell with its own indicator.
Important: If you own several systems, make sure that each load cell is used with its original indicator. Load cells and indicators are calibrated as matched pairs and are non-interchangeable.

At all times, it is the responsibility of the user of this equipment to ensure that normal safety precautions are observed. No amount of safety features and engineering can be a substitute for common sense and a desire to work safely.
