MD700/1100/1200 Axle Scales Heavy Duty and Semi-Portable
The MD700/1100/1200 is an axle truck scale used in heavy duty applications made of solid aluminum. The scales also make use of our patented load cell design, which is wireless capable.
When it comes to heavy duty axle scales design, GEC has the expertise and knowledge to assist in your weighing needs. For over 40 years, GEC has led the field in heavy-duty scale design and manufacturing
Three sizes and capacities from which to choose. Whether you choose the MD700, MD1100, or MD1200, you are choosing high-performance scales designed to withstand the rigors of routine and regulatory weighing. All the MD series scales make use of a unique load cell design and are made of only the highest quality materials resulting in consistent high accuracy, repeatability, and longevity not found in similar scale systems. With a capacity up to 120,000 (split axle), GEC's transportable, semi-portable axle scales can handle virtually any heavy truck weighing job almost anywhere.
Solid Aluminum Weigh Bridges can take high volume weighing without fatigue or failure. They are made of solid, high-strength 6061-T6 aluminum - eliminating down-time caused by welded steel bridge failures.
Patented Load Cell Design: GEC uses its patented Hydraulically Actuated Electronic Load Cell (HAEL) to obtain highest accuracy. Hermetically sealed, the HAEL load cells are moisture proof and provide pinpoint accuracy throughout a wide temperature range. Self leveling by design, the load cells counteract the effects of side loads due to surface irregularities.
Easy Setup: GEC semi-portables are proven as the most reliable and trouble free axle scales available. Easy Setup is assured with GEC axle scales. They are shipped fully assembled, and ready to use.
Box End Ramps: The GEC axle scales can be recessed in shallow pits for semi- permanent applications. Simply replace the entry/exit ramps with the box ends and install in the pit.
Transport Trailer: On person can install the axle scale system quickly using the tilt-bed transport trailer. Equipped with storage/tool box and an electric winch, the trailer makes unloading and loading the scales easy and safe.
Weight Indicator WI300: This NTEP-approved instrument indicates on up to 4 channels. It has an accumulate feature and can be configured for either split axle weighing or 200 truck in/out modes. The WI300 is self contained in a carry case and can be equipped with either an internal or external printer to print custom formatted weighing ticket forms.
