Monorail Carcass Scales

Weigh carcasses in motion. NTEP approved Morrison monorails are an industry leader. Over a billion pounds are weighed and paid off of Morrison monorails each month in the United States.

weighting system

At Morrison Weighing we have produced precise and reliable monorail scales for more than 50 years.

NTEP approved Morrison Monorail scales are available for beef, pork, lamb, product hanger, and trolley weighing applications. Each monorail scale has a standardized load cell output which is compatible with Morrison indicators as well as the majority of other indicators on the market.

Motorized monorail scales automatically transfer hanging carcasses along the rail while taking an accurate weight in high-speed motion. As is standard in most slaughter operations, the scales are NTEP approved for “Hot Scale” weighing to pay producers, as well as “Cold Scale” weighing for data collection and measuring shrink.

The benefits of choosing a Morrison monorail scale for your business

Morrison monorails provide the excellent accuracy required to pass governmental inspection year after year. Maintenance is simple, saving your staff time and reducing the risk of costly and aggravating mistakes. We support our products for life and are readily available when you need us. With Morrison, you can be sure you’ve installed an industry-trusted scale that will stand the test of time.


Designed to last

Properly maintained Morrison monorails regularly exceed 20 years of continuous use in the field. Our 50+ years of experience building monorails have allowed us to finetune our design for maximum performance. The current models offered combine our real-world knowledge from countless installations with the best of modern engineering. To pair with the long-lasting design, we ensure service and spare parts are always available for our equipment regardless of how long you’ve had it.

Inexpensive maintenance

Morrison’s motorized monorails are mechanically engineered to achieve high speed NTEP approved accuracy without the need for a “transition rail” or custom chain. This improvement reduces required maintenance and drastically reduces lifetime spare parts cost.

  • No “transition rail” - By achieving high speed NTEP approval without the use of a transition rail, Morrison monorails require less maintenance, and provide higher reliability. No more need for regular maintenance teardowns to replace internal moving parts of a transition rail.
  • Heavy duty chain - Morrison in-motion monorail scales are designed to use heavy-duty chains from a mass-production manufacturer. The cost of these chains is up to 80% less than the complex chains required to operate competitors’ monorail scales. Furthermore, Morrison’s chains’ robust design helps them last longer than the competition, saving even more replacement parts cost in the long run.

Prompt and reliable service

We know that the success of equipment isn’t determined on the day of sale, but instead in the months and years of operation that follows. Morrison Weighing systems technicians are readily available whenever you need them and parts are quick and easy to order. On-site service calls are available on an as-needed basis, with no expensive service contracts or red tape.

In addition to on-site service, all Morrison equipment comes with lifetime free technical phone support. Call us for free, anytime, and speak with an experienced technician or engineer who will help you work through any issue you may have.

As a long time Morrison Mono-Rail carcass scale user, I can attest to its solid performance and ease of maintenance. Maintenance, when required, is simple and fast. Annual review by GIPSA and/or Weights & Measures for over ten years with no issues. Will continue to be a Morrison customer.

We understand the need for robust and reliable equipment and software. Our production floor data entry systems withstand even the toughest of washdown conditions and are easy to maintain. Our software is easy to use and written to operate without the risk of errors. It easily records data with backup files and the ability to feed data into other plant-wide software systems in real time.

Choosing Morrison for your Hot and Cold Scale is choosing the team with the experience and background necessary to ensure a successful project.

Static Weigh Rail

Static monorail scales

In addition to our motorized monorail scales, Morrison offers static monorail scales for smaller operations. The static scale requires carcasses to be pulled onto the scale and let rest momentarily before taking the weight. This is an inexpensive solution and great for small to midsize operations.
