Cranescales are designed for heavy loads in the weighing range from 1000 to 100,000 kg. However, the fact that these also have to be extremely precise, easy to operate and easy to read is usually not considered. Cranescales can also withstand high environmental influences, such as the effects of water, high temperatures, infrared radiation, etc. Suspended scales have digital filters and programmable, automatic switch-off options are practical additional features. These scales can even be operated without cable connection, in battery mode. Solar radiation on the LED displays is no problem. Remote data transmission by radio is already part of the standard program almost everywhere. The operation with a remote control makes the daily work with heavy loads much easier. Calibratable models of cranescales are also available. Maintenance, cleaning and repair are, of course, already covered, are problem-free and relatively easy to manage.
Cranescales are only used for industrial and commercial operations. The scale is either an integral part of the crane or is hung on a hook on the crane. All rope guide parts as well as the rope drum with drive are mounted on the weighing bridge as preload. The weight is suspended from the load hook, then weighed and finally placed where the load is to be placed. This is particularly practical when the cargo of a ship is to be discharged. The weighing data are nowadays transmitted by radio transmission up to 8 m to a PC, label printer or general printer. Many scales have an integrated totalizing function so that all partial masses can be added together. But also the trim, i.e. the safe distribution of the cargo on the ship, can be controlled very well by the crane scale. That is why ship loads are nowadays only positioned on ships by cranescales. Colls, ladles, sheet metal, bar iron, etc. are tared. In foundries, heat protection and heat resistance are of course necessary and given. Over 200 tons of so-called tensile measuring plates are used. The automatic switch-off function, a solid metal housing and a sealed keyboard provide additional operational safety. Tare deductions are possible both manually and automatically. Remote data transmission is possible for one or more cranescales, PC, but also printer. Fast programming with Dinitools is also available. Moreover, many different additional data processing features are available for logistics and accounting sectors.
A crane scale is used both in industry and in business parks or in shipyards or ports. Cranescales are particularly important for the positioning of ship loads. Here it is important that the ship is not overloaded and that the cargo is placed evenly. The fixed stowage ensures that the cargo can no longer slip afterwards. If the cargo were not evenly distributed or not secured, the ship would capsize or the crew would be injured by parts of the cargo. The cranescales have an important safety function. Some shipyards already have cranescales on site. In shipyards these are standard equipment, as often large parts of the ship have to be weighed and moved. A further field of application would be fire-fighting planes. Here, the function is assigned to the lifting arm on which the extinguishing containers are suspended. The helicopters fly, for example, over a lake and take in water during the flight. It is especially important that the load is not too heavy, otherwise the helicopter itself would crash. Also cranescales in the harbour are sometimes used as "fire fighting tools". But also in shipyards, on industrial areas cranescales are used to extinguish fires. On the crane hook any kind of fire-fighting material, even heavy sacks of earth, etc., can be suspended and then unloaded relatively safely above the source of the fire. In this way, fires are often extinguished quickly and safely without endangering people (proximity of fire, high heat). Fires are among the greatest dangers in industrial areas, shipyards, harbours, etc. It is therefore always advisable to have equipment that is quick, simple, safe and suitable for these operations. In addition, cranescales with their robust and stable construction can also withstand such extreme requirements and applications.
This makes them a helper in an emergency and an indispensable all-rounder. Renting cranescales would not make sense, as these scales are normally operated in continuous operation. For smaller companies, however, even used versions that are still fully functional will always pay off. The verification and calibration are of course also of great importance for this version of industrial scales. A new crane scale that is to be calibrated must be calibrated before the first use. Subsequent verification is no longer possible ex officio.
