There’s been a lot of progress in the development of efficient vehicle weighing systems over the past few years; especially in the areas of product mobility and pinpoint accuracy.
Portable truck scales are among the most common weighing systems today. However, there are still important distinctions between the various types of portable truck scale systems. Two of the most popular forms of scales used for measuring a vehicle’s weight are portable wheel weighers and the portable axle scales. Below we weigh-in on both of these systems and what features each provides.
Portable Wheel Weighers
This form of scale is the most versatile and cost effective way of weighing a vehicle as in theory they should give you the ability to weigh any vehicle anywhere, anytime. Usually constructed out of a single piece of aluminium these scales come in single wheel units, therefore four units are required to weigh a standard two-axle vehicle. This kind of portable wheel weigher scale can usually weigh items up to 10,000 kg (20,000 lbs) accurate within 1%.
Because of the portable nature of this type of scale, they are best used for scenarios where the product that is in need of weighing is ‘away from base’ or where the weight is not going to be particularly high. However you begin to encounter problems when the weight does begin to reach, and exceed, the upper levels of weight and especially when you’re dealing with vehicles that have more than a lot of axles, as obviously, you’ll need more units at hand, all of which need to be synchronised together.
So for any vehicle that isn’t used in heavy industry or large freight transport, the portable wheel weigher will be the most convenient and economical option. Get more info about portable wheel weighers at WalzScale.com
Portable Axle Scales
When you are dealing with heavy industry equipment such as mining trucks, the axle scale provides the best alternative for when the portable wheel weigher becomes ineffective or impractical.
These scales are designed as weighbridges which are the length of tucks and are therefore not hindered by the number of axles the subject vehicle has. These truck scales are built out of heavy-duty carbon steel in order to deal with the extra weight they are expected to hold – which is as much as 50,000 kg (100,000 lbs).
Although traditionally harder to transport than portable wheel weighers, and are therefore better suited to be permanently installed ‘on base’ portable versions are becoming the norm. However, the practicality of the site in which an axle scale is being installed must be considered in ways that aren’t necessary for portable wheel weigher. For example, the land must be firm, level and at least the length of one vehicle.
Another benefit of using axle truck scales is they can be operated in two ways, statically – the vehicle stops, gets weighed then moves on- or, when a vehicle is in motion , (e.g. vehicles with self-compensating suspension systems) which gives the best result when weighing extremely vehicles; this is something most portable wheel weighers cannot do.
Which Truck Scale is Best for Your?
For most operations that require weighing a vehicle, the best option will be several individual units of portable wheel weighers – ensuring you have enough to match the number of axles you intend to weigh. However, for those enterprises that are involved in heavy industry and are required to weigh much larger and heavier vehicles the, best option is the portable axle scale.
