With the constant changes in modern technology, all types of weighing equipment have come a long way from the original, see saw type of weighing. 10 years ago, a crane scale would have been similar to a large dial type scale which is full of springs and levers.
Modern weighing equipment consists of the latest, cutting edge materials and microchip processors. At the heart of any crane scale is a load cell. This is basically a block of alloy or steel which draws power from the circuit board and, in return, gives a mill volt signal which is processed and gives and accurate reading to the display. Crane scales are engineered for all types of industrial applications and can be found in all types of factories and industrial applications today. The outer shell is generally constructed from industrial grade steel or heavy duty aluminium, which provides good durability and protection to the crane scale. The outer shell construction depends on the capacity of the weighing scale and also its application. Small capacity scales for general industrial use are made from aluminium, high capacity scales tend to be made from a more heavy duty, steel construction.
Crane scales are also found in many industrial foundries and are supplied with a heat guard to deflect the heat and protect the scale. As with most weighing scales, two types of display are used, either LCD (liquid crystal display) which is very easy to read in direct sun light and ideal for outdoor use or LED (light emitting diode) for use indoors. LCD displays come with a built in back light. Power is supplied via an internal rechargeable battery, with today’s technology can give from 10 to 60 hours minimum battery life when continuously working. LCD display crane scales draw far less power from the batter and give a greater working life before the need for its next charge. Most crane scales have an auto shut function to help conserve on power.
Modern crane scales offer many features to allow the user to achieve good dynamic weighing performance, not subjected to the influence of swaying, a built in filter enables the user to adjust the stability depending on the application. You are also able to switch the display from kg’s to Lbs and also hold the display on a particular weight should you need. There are many different capacities and resolutions to choose from, here are some examples.
– 1.5 ton capacity x 0.5kg increments
– 3 ton capacity x 1kg increments
– 5 ton capacity x 2kg increments
– 10 ton capacity x 5kg increments
– 15 ton capacity x 5kg increments
– 30 ton capacity x 10kg increments
– 50 ton capacity x 20kg increments;
Crane scales generally have a safe overload feature of 120% of their capacity and a maximum overload of 150% of their capacity to prolong the life of the load cell.

Most models can be supplied with a remote control allowing the user to be able to hold the weight, tare the weight, switch units or power the scale on, or off within a 100 meter range. More expensive crane scales also have the availability of having a remote display which can be hand held or bench mounted to allow the user to read the display weight with great ease.LIKED ARTICLE: Types Of Crane Scales And Their Uses< / strong> – share a link to OUR< / a>< / strong> website
