key features to consider when buying safe load indicator for crane

A safe load indicator is a device installed on cranes to inform the crane operator whether the load being lifted is within the allowed weight range or exceeds the safe machinery operating range. some safe load indicators will lock the crane automatically if they determine the load being lifted exceeds the acceptable weight.

Features of a good safe load indicator:

This is important to purchase a device that will serve its intended purpose. When shopping for an ideal safe load indicator, these are some of the key factors to look out for.

1. High Linearity:

This is one of the important factors to effective measurements. Linearity refers to the accuracy of measurements of a device over the full range of measurement. How accurate is the reading on the device compared to the actual weight of the load device compared to the actual weight of the load being measured? High linearity shows that the safe load indicators is reliable and can be trusted to give accurate readings all through without showing the tenacity to the erratic. A customer should, therefore, opt for a device that has this property.

2. Dual or single load monitor:

This is another feature that distinguishes safe load indicator devices. A customer can choose to buy either a single or a dual load monitor depending on the sustainability of the device and the reason for which it is being purchased. Dual load indicators can monitor two loads at the same time if the crane is designed to lift two loads at a go. A single load monitor device, on the other hand, can only monitor one load at a time.

3. Total load of all the hooks:

Some devices can indicate a total load of all hooks in a crane. It can be applicable if the safe load indicator has a dual load monitor. The person operating the crane will be able to know the total load lifted by the hooks at a glance. It is a feature that many customers find appropriate.

4. Overhead hoisting Protection:

Lifting loads that exceed the safe operating range of the machines can cause damages to the crane. Such loads also pose a severe danger to the employees. Overhead hoisting protection, therefore serves to safeguard against the negative impacts of lifting weights that exceed the acceptable limit. There are different types of overhead hoisting protection devices such as electrical, chain hoist, and mechanical overhead protective devices.

Other significant features of crane safe load indicator devices are alert conditions, wind speed, hook travel, boom length, boom tip height, crane tilt, slewing angle, rugged construction, and wire rope deployment
