Single-Axle Weighbridge

The Ton-Tel Single-Axle weighbridge is an accurate weighing system which will weigh any type of vehicle regardless of its length or the number of axles it has. As a vehicle moves across the platform at slow speed an electronic control computes and logs the weight of every axle.

The heavy duty construction has been built to work in harsh conditions and is particularly suited to installations where high volumes of traffic are being weighed.

Close Coupled Axles

The platform has been specifically designed to take all combinations of axles. Single axles, tandem and tri-axle combinations are easily weighed because the electronics can capture the weights of every axle individually.

Close coupled axles with spring or air suspension are no problem to the weighbridge which will take individual axles of up to 30 tonnes each.

Law Enforcement

A range of indicators and computer software is available for the Ton-Tel which allow authorities to choose the best system for their enforcement needs. The Ton-Tel is particularly suited to use where compliance with legislation is important as 'overspeed' weights are automatically detected so that vehicles cannot be presented with incorrect weighing tickets.

The policy of Griffith Elder is to produce only top quality products incorporating the latest technological advances. Particular emphasis is placed on product reliability and durability and so the company undertakes all its own design and manufacture in order to maintain the essential high level of quality control.

Dynamic Weighing

In-motion (dynamic) weighing is an established feature of axle weighing and was originally developed by Griffith Elder in the early 1980s. It is the basis of the Ton-Tel system and today with modern, state of the art electronic circuits it provides the highest accuracy for weighing individual axles.

As a vehicle drives over the weighbridge in low gear the axles are automatically recorded on the move. The electronics calculates the actual weight of each axle as it passes over the platform and immediately displays the weight.

Automatic operation of the weighbridge allows a driver to weigh without the need for a specialist operator to be present. A unique electronic zeroing system ensures that the correct weight is achieved for each axle and that zero adjustment between weighings is not required.

Installation

Griffith Elder recognise that siting of a single axle weighbridge is of prime consideration and so we offer an advisory service for location, backed up by easy to follow instructions and technical assistance.

There are two essential rules which must be followed when weighing axles, namely: a) the weighing platform must be ecessed into the ground at a prepared site and b) the approach and exit to the weighing platform need to be level to the full length of the longest vehicle to be weighed. Accuracy will be compromised if the approach and exit roadways are not completely level within normal concreting tolerances. Use of our pit frame simplifies the construction and ensures that the weighbridge is located correctly.

The Griffith Elder guide for installation is a comprehensive manual which describes in detail the whole civil works operation. Our civil engineering team are able to give advice and we can also provide a complete turn-key package, undertaking all aspects of the installation and commissioning.

Maintenance

Where the Ton-Tel single axle weighbridge is to be used for law enforcement purposes Griffith Elder personnel can train your staff in calibration, regular check-up procedures and maintenance schedules. We provide on-going support so that the equipment will give many years of trouble free service.

The Ton-Tel is designed with cost of maintenance in mind and has a record, since Griffith Elder designed the first dynamic single axle weighbridge using strain-gauge loadcells in 1982, of very low total cost of ownership. All products are committed to an extensive field assessment programme after development, both at pre-production and final production level which enables us to maintain our reputation of supplying equipment which will have a long and trouble free life.

Construction

The strength of the Ton-Tel single axle weighbridge is the single piece welded platform. High quality steel beams form the superstructure and the platform deck is 10 millimetre flat plate to ensure optimum rigidity. The heavy duty construction and implicity of design make the Ton-Tel a weighbridge which will last for many years.

The four sensors which actually detect the weight on the platform are welded stainless steel loadcells that have been designed by and are manufactured by Griffith Elder. The robust design gives high reliability, low maintenance and long service life, whilst still providing very high accuracy for the weighing function.

An electronic controller takes the signals from the loadcells and turns them into weights. This is done right there in the platform so that there is no distortion of the result because of long cable runs. The signal which is sent to the computer or terminal is digital and so is immune to interference of the type typically found in less advanced products.

A single low voltage cable comes from the platform to a terminal which may be a simple indicator or a sophisticated computer. Each has its merits according to the purpose of the weighbridge, but both are made to be robust and serve the purpose of weighing many vehicles quickly and easily. Traffic lights, large display and other ancillaries like vehicle transponders and traffic control barriers are controlled from the terminal so that the weighing function is separate from the display and reporting functions.
