A weighbridge is a large and heavy-duty industrial weighing scale, also known as a truck scale or railroad scale, used to weigh vehicles and their loads, especially road trucks and trailers. They are typically used for commercial and industrial purposes such as determining the weight of trucks for transportation purposes, trading, compliance with weight regulations, and inventory management. They are typically found at ports, truck stops, and transfer stations. They can be either portable or permanent, and can be operated manually or with electronic equipment.
Petra is a weighbridge supplier in UAE. Providing sales and service of weighbridge equipment such as load cells and indicators to many weighing scale companies in Abu Dhabi, Dubai, Sharjah, and Ajman – all backed by industry-leading warranty options.
The main components of a weighbridge include: the platform, load cells, indicator or computer, ramp, junction box, printer, and power supply. These components work together to accurately measure the weight of vehicles and their loads. Some weighbridges may also include additional features such as wireless connectivity, data storage and retrieval, and remote monitoring capabilities.
Weighbridges are commonly used in a variety of businesses and industries that involve the transportation of goods or materials. Some examples include:
These are just a few examples, weighbridges are used in many other industries as well.
Weighbridges or truck scales are based on static or dynamic weighing mechanisms. Static weighbridges are used to weigh a vehicle when it is parked, while dynamic weighbridges are used to weigh a vehicle while it is moving.
There are several types of weighbridges, including:
All these types of weighbridges are available in electronic versions and can be operated manually or with electronic equipment.
Petra is a weighbridge manufacturer and supplier, that specializes in the production of various types of electronic weighbridges, such as Pit Less (Surface Mount) Weighbridges, Pit Type Weighbridges, and Portable Weighbridges.
A Pit Type weighbridge, also known as an Inground weighbridge, is a type of industrial scale that is installed in a pit or excavation in the ground. The scale is level with the ground surface (so a ramp will not be needed), allowing vehicles to drive onto the scale for weighing from any direction. The pit is typically structured with concrete, and the weighbridge is installed on top of the concrete pit.
Most public weighbridges prefer this design.
Pit-type weighbridges are commonly used in locations where space is limited, such as in industrial sites, ports, and transfer stations. Because the scale is at ground level, it is easier for vehicles to drive on the scale
They are available in different capacities and sizes to accommodate different types of vehicles and loads.
One of the advantages of the pit type of weighbridge is that it provides a stable foundation for the weighbridge, which helps to improve accuracy and longevity. Additionally, the pit provides a level and stable surface for the weighbridge, which helps to improve accuracy and longevity, and also reduces the risk of damage to the weighbridge from heavy vehicles.
Points to be considered
Surface Mount Weighbridges, also known as Pitless Weighbridges, is a type of industrial scale that is installed on the ground surface, rather than in a pit or excavation. They do not require a pit for installation and can be placed on any level surface. But it requires a ramp with a length between 3-5 meters long base on the height of the weighbridge weighing surface
Suitable where the excavation work for the foundation is difficult or construction of the pit is expensive
Surface Mount weighbridges are commonly used in locations where space is not limited or where a pit is not feasible, such as in commercial and retail settings, agricultural and farming operations, and construction sites. They are also used in places where the ground conditions are not suitable for pit-type weighbridges.
Surface Mount weighbridges are available and come in different capacities and sizes to accommodate different types of vehicles and loads.
One of the advantages of Surface Mount weighbridges is that they are more versatile and can be installed at any location, unlike pit-type weighbridges which require a pit for installation. Additionally, they are easy to install and maintain and are less prone to damage from heavy vehicles. They are also more cost-effective than pit-type weighbridges, as they do not require excavation and construction of a pit.
Points to be considered:
Portable weighbridges, also known as mobile weighbridges or movable truck scale, are industrial scale that is designed to be easily transported and set up in different locations. They are used for temporary or mobile applications such as construction sites, agricultural operations, and events where weight needs to be measured. They are made of a steel platform that can be mounted on a trailer or skid for easy transportation. They can be powered by electricity or battery, and can be operated manually or with electronic equipment.
These weighbridges come in different capacities and sizes to accommodate different types of vehicles and loads. They are available in both electronic and mechanical versions and can also be single or multi-axle versions, which can weigh the vehicles and loads with a higher degree of accuracy.
The main advantage of portable weighbridges is that they are highly portable and can be used in a variety of locations, making them ideal for temporary or mobile applications. They are easy to set up and take down, require minimal maintenance, and are cost-effective as compared to permanent weighbridges. With short assembly times, these weighbridges are easy to transport and re-install and do not require a foundation. They are also modular and cost-effective, which makes them a good option when there is a cost or time constraint.
In-motion weighbridge, also known as a dynamic weighbridge or dynamic axle weighbridge, is a type of industrial scale used to weigh vehicles and their loads while they are in motion.
Typically found at ports, truck stops, and transfer stations, they are used for taxation and compliance with weight restrictions on roads and bridges.
They are made of load cells placed under the roadway, which measure the weight of each axle of the vehicle as it passes over the scale, allowing for accurate determination of the total weight of the vehicle and its load.
They are known for their speed, efficiency, and safety as they can weigh the vehicle without stopping it.
Self-service weighbridges, also known as automated weighbridges or unmanned truck scales, are standalone industrial scales that are designed to be operated by the vehicle operator or driver rather than by a weighbridge operator.
A weighbridge typically consists of the following main components:
Weighbridges additional features and accessories
Some weighbridges also include additional features such as wireless connectivity, data storage and retrieval, and remote monitoring capabilities.
All these components work together to accurately measure the weight of vehicles and their loads. The quality of the weighbridge’s main components will determine the accuracy of the weighing process.
