With the constant changes in modern technology, all types of weighing equipment have come a long way from the original type of weighing saw. 10 years ago, a crane scale would have been similar to a large dial scale full of springs and levers.
Modern weighing equipment consists of the latest state-of-the-art materials and microchip processors. At the heart of any crane scale is a load cell. Basically, it is a block of alloy or steel that draws power from the circuit board and in return provides a thousand volt signal that is processed and provides an accurate reading on the display. Crane scales are designed for all types of industrial applications and can be found in all types of factories and industrial applications today. The outer casing is typically constructed of industrial grade steel or heavy-duty aluminum, providing good durability and protection for the crane scale. The construction of the outer casing depends on the capacity of the scale and also on its application. Small capacity scales for general industrial use are made of aluminum, high capacity scales tend to be made of stronger steel construction.
Crane scales are also found in many industrial foundries and are supplied with a heat shield to divert heat and protect the scale. As with most scales, two types of display are used, either LCD (Liquid Crystal Display), which is very easy to read in direct sunlight and ideal for outdoor use, or LED (Light Emitting Diode). ) for indoor use. LCD screens come with a built-in backlight. Power is supplied via an internal rechargeable battery, with current technology it can provide 10 to 60 hours minimum battery life in continuous operation. The LCD display crane scales consume much less energy from the dough and provide a longer shelf life before the need for your next load. Most crane scales have an auto shut-off feature to help conserve energy.
Modern crane scales offer many features that allow the user to achieve good dynamic weighing performance, without being subject to the influence of sway, a built-in filter allows the user to adjust stability depending on the application. You can also change the display from kg to pounds and also keep the display on a particular weight if you need to. 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 5 kg increments
– 30 ton capacity x 10kg increments
– 50 ton capacity x 20 kg increments;
Crane scales typically have a safe overload function of 120% capacity and a maximum overload function of 150% capacity to extend load cell life.

Most models can be supplied with a remote control that allows the user to hold the weight, tare the weight, change units or turn the scale on or off within a range of 100 meters. The 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 weight from the display with great ease.
