There are two types of scales used to weigh trucks; axle load scales and full length truck scales. Axle load scales can weigh one or two axles at a time. Full length truck scales can weigh the entire truck at a time. Axle load scales are less expensive but they are subject to certain errors. Full length truck scales may be either portable or permanent installation. Portable truck scales are generally placed on a prepared surface (concrete slab, wooden beams or even dirt) and ramps are placed at either end for access. Portable scales are more expensive due to lower framework. But the biggest advantage is it is easy to move from one site to another and is ideal for contractors or road builders. Scales that are permanently mounted may be mounted either in a pit or of an above-ground low profile design where the scale is mounted on a concrete slab with ramps at either end. Advantages of Pit type scale are: There is no requirement for entry and exit ramps, snow will not be accumulated beneath the platform and easier access to the bottom of the scale. The Cost of a pit type scale is greater because of the increased cost of excavation and pit construction.
When you’re planning to buy a weighbridge for a particular operation, it is important to take into account the following: The amount of weighing expected, type of vehicle to be weighed, whether it is of part length weighbridge (Cart / Mini Weighbridge) or gross weight weighbridge (Pit or Pit less type). Pit less type weighbridge are generally mounted above road level. More space is required when compared to pit type Weigh Bridge. This type of Weigh Bridge is used in rocky land or where there is water logging problem. Pit type Weigh Bridge requires less space and ramps are not required for loading and unloading of vehicles.
Cart or Mini Weighbridges are called Part Length Weighbridge. These weighbridges are used to weigh agricultural tractor and trailer combinations and bricks manufacturing unit. Other types of weighbridge are Low profile scale, Concrete Deck, Steel Deck, Full electronic, Electromechanical, Bumper Bolt Restraint and Check Rod restraint. Low profile scales are less expensive, available in a portable model and fewer problems with water drainage. Concrete Deck doesn’t rust easily and is unaffected by chemicals. Steel Deck requires less initial cost, less labor required, doesn’t crack easily. Electromechanical requires simple wiring, junction boxes not required, less power required and less susceptible to lightning damage. Bumper Bolt restraint is simple to install and is inexpensive. Check Rod restraint does nor require maintenance and does not allow movement in weighbridge. You may be thinking about weighing capacity. There are two capacities associated with truck scales. The first, nominal capacity can measure upto 200,000 pounds which is more than sufficient to weigh highway trucks. The second one being, concentrated load capacity can weigh about 2,000 pounds and vary from 20 tons upto 50 tons.
