Dangerous overload situations may occur during lifting activities for several reasons. The first one being not knowing the lifted load's weight. When the weight is unknown, no matter how experienced the crane operator is, weight evaluations are not accurate enough and may cause a dangerous overload.

However, unknown weight is only one of the reasons for overload. Even when the weight is known, dangerous overload may still occur. For example:

Trying to lift equipment which is anchored. This situation may happen due to unreleased bolts that still fix the equipment to the ground, or if the equipment is secured to other equipment which is very heavy.

When several people are responsible for lifting, lack of coordination between them may cause them to lift more than the safe working load, or to add equipment after the total lifted load has been calculated and approved.

Side loading, which is dangerous for any lifting equipment, especially for jib and tower cranes.

Unequal distribution of the load when several lifting points are used to lift a single construction or object: Even if the total load does not exceed the total safe working load of all the lifting points together, some of the lifting points may be overloaded while others carry less load.

Crane overload is very dangerous and may cause accidents. It must be prevented. RON Crane Scales help to control overload and prevent it.

Crane overload control and prevention may be achieved by using weighing systems such as crane scales and dynamometers, or overload warning systems:

1. Weighing systems are electronic crane scales and dynamometers that measure the load, display the value and trigger an overload warning or alarm whenever an overload situation occurs.

2. Crane overload warning systems are crane overload detectors that help to monitor, detect and prevent overload situations by triggering an overload warning or alarm whenever the preset threshold is reached due to an overload situation.
