Modern Safety and Other Features on Overhead Cranes


Overhead cranes are now built with modern safety features and other features to make their operation as efficient and safe as possible, and these features can often be added onto older cranes fairly easily. There are dozens of new safety features for overhead cranes that have been developed over the past decade or so, however even older overhead cranes can still be safe and efficient depending on their use and work requirements. The good thing is that many older cranes can be upgraded or modernized with a retrofit, and new safety features can be added onto them to improve their features without having to purchase an entirely new crane. This is often preferable, especially for companies that are trying to maintain their older equipment.

Target positioning is a new feature on some overhead cranes

Target positioning is a new feature that can be found in some overhead cranes, and this feature allows preset target positions as well as home positions. This can make moving a load very easy because the positions are already programmed into the crane, and the load will automatically be moved to a target position as precisely and safely as possible. The hoist can be programmed to raise or lower the load to a specific height with this feature. This type of feature is very useful in situations where the operator must repetitively move the same type of load into the same position over and over again, and it can be a way to reduce errors and minimize risks.

Working limits are another new feature

Working limits can set up a “virtual wall” where the crane cannot move a load past a certain point. This feature essential limits the movement of the crane to a very specific area, and it can protect workers who are near the crane or protect special equipment. There are usually rail stops or limit switches on cranes, but a working limit can protect equipment and people as an extra measure. Working limits prevent the crane from moving throughout a predefined location, and it can make the job of operating the crane much easier for the operator. It can protect vehicles and goods from damage from the crane and it may be desirable in some facilities where the cranes work in close proximity to people and equipment.

Adaptive speed is another new feature

Slower cranes can be used to move more delicate loads, but the slower speed can result in a lower work efficiency. There is a new feature available on some cranes called adaptive speed which can increase moving speed safely without having to change out the motor. Adaptive speed can increase the speed of hoisting when lighter loads are used, and it can be used to slow down the speed when there are larger and more dangerous loads. Full capacity loads are moved at a slower speed so that the operator has the maximum control, and this type of feature is normally available on overhead cranes that do not have high capacity loads very often but occasionally need the capability to lift them.
