Introduction to Available Products

Hawkley International supplies a wide range of vehicle weighing equipment suitable for weighing small lightweight karts and cars through to large commercial vehicles.

This guide, developed from experience of over 25 years in the business, attempts to provide an objective view of the various types of weighing systems available on the market, and the considerations to be taken into account prior to purchase. A prospective customer of vehicle weighing equipment is well advised to understand these underlying issues before committing to a purchase.

Systems can be categorised into one of the following: -

• Portable wheel or axle weighers

• On-board weighing system

• Single axle weighbridge

• Full length plate weighbridge

• Part length weighbridge

Portable Wheel Axle Weigher

This is probably the most versatile method of weighing as in theory it should be possible to weigh any wheeled vehicle, anywhere, anytime. However the more axles a vehicles has, the more units one needs to weigh it correctly and the more time it may take to do this. It is also easier to cause weight transfer with this type of equipment. For two axled vehicles, for 'off site'/'away from base' weighing, or where the weighing demands are not particularly high, this is probably the most cost-effective method of all.

On Board Weighing

The advantage of these systems are that they are installed either as Original Equipment or After Market products, and adds functionality to vehicle information. Increasingly these systems are becoming compatible with Satellite and GPS technology to enable drivers and fleet managers to control the weights of their vehicles. Since these systems are on-board, they cannot give either axle or gross vehicle weights as they can only register weights that are 'above' them, although these elements can be easily set. Each vehicle requiring to be weighed has to have a system fitted and this can prove costly for multi-vehicle operations.

Single Axle Weighbridge

With the exception of the two axled vehicles mentioned above, this type of weighbridge provides the easiest and quickest method of obtaining axle weights of all types of road vehicles. Most single axle weighbridges can be operated either statically (stop and go), or dynamically (in motion) which gives the best results when weighing large vehicles with self compensating suspension systems. The most important factor when considering installation of an axle weighbridge is the suitability of the site, which must be firm, flat and level for at least one vehicle length, either side of the weighbridge platform if reasonable results are to obtained. The risk of weight transfer during the weighing will be the determining factor in levels of accuracy, irrespective of the inherent accuracy of the weighbridge.

Full Length Plate Weighbridge

This type of weighbridge gives the highest levels of accuracy for gross vehicle weights and may be tested and stamped for trade use. Plate weighbridges are usually 15 or 18 metres long with capacities ranging from 50 to 100 tonnes, thus they can accommodate even the largest road vehicle. However they are quite expensive and installation costs can add considerably to the final price. A plate weighbridges can be used to obtain individual axle weights provided it is pit mounted (not surface mounted) and that the roadway adjacent to the weighbridge is firm, flat and level.

Part Length Weighbridge

These weighbridges are usually 3 or 4 metres long and are most frequently found on farms where they are used to weigh agricultural tractor and trailer combinations. They are essentially a compromise between a full length and an axle weighbridge, and should cost less than the full-length weighbridge. Part length weighbridges can be used to obtain tractor and trailer bogie weights of large articulated trucks and also individual axle weights of other road vehicles provided (as in the case of full weighbridges) that the adjacent roadway is firm, flat and level

Options & Accessories

Many manufacturers of vehicle weighing equipment can design and build systems to meet individual customer's requirements, or can supply a wide range of accessories with standard products. Such options may comprise special indicators, printers and software packages to enable information to be integrated with access and control equipment, specific software, radio, satellite and GPs systems.
