What it is

What is a twin track (birrail) overhead rail?

A twin track overhead rail is a transport system suspended from the ceiling or a steel structure, made of two parallel aluminium rails on which trolleys with hooks, gambrels or pendants run. It is used to move carcasses, half carcasses and hanging cuts between the different areas of a meat plant —slaughter, chilling, cold rooms, cutting and dispatch— without the product touching the floor and without operators carrying the weight.

  1. The track (rail and brackets) is anchored to the structure with clamps and stainless steel fixings.
  2. The trolleys run on both rails and carry the hook, gambrel or pendant holding the meat.
  3. Curves, switches and points send each trolley to its destination: a cold room, the cutting room or the loading dock.

At Bernad we design it for each building and integrate it with the rest of the facility: cold rooms, drying rooms and slaughterhouse machinery.

Applications

Overhead rail for every kind of meat plant

We have installed overhead rail in slaughterhouses, cutting rooms, cured meat factories and food distribution companies. These are its most common applications.

Slaughterhouses

Carcass transport from the line to chilling and the carcass rooms, with switches to distribute the product and trolleys for each species.

Slaughterhouse machinery →

Cutting rooms

Carcasses arrive hanging at the work tables and cuts are organised on hangers, with no manual lifting.

Advantages

Why install overhead rail in your plant

Easy assemblyMinimal maintenanceEasy cleaningHigh strengthExcellent mobilityFits any spaceOwn design and manufacturing
Time savings

Carcasses and cuts roll along the rail, from the line to the cold room and from the cold room to cutting or to the truck.

Better use of space

The product hangs and leaves the floor free; curves and switches adapt to the shape of each building.

Easier, safer work

Staff push the load instead of lifting it, avoiding the overexertion that can lead to injuries.

Frequently asked questions

FAQ about overhead meat rail

What is a twin track (birrail) overhead rail?

It is a suspended transport system made of two parallel aluminium rails, anchored to the ceiling or a structure, on which trolleys with hooks, gambrels or pendants run. It is used to move carcasses and hanging cuts between the areas of a meat plant without touching the floor and without operators carrying the weight.

Where is it used?

In slaughterhouses, cutting rooms, carcass and chilling rooms, cured meat factories and drying rooms, and dispatch and truck loading areas. We design it for small installations as well as large processing plants.

What materials is it made of?

The rail consists of two extruded 6063 aluminium alloy profiles. Brackets are aluminium and fixings are stainless steel. Trolleys have an aluminium body and PA6 nylon wheels and rollers with bearings, and hooks, gambrels, pendants and hangers are stainless steel.

How much load can the overhead rail carry?

It depends on the suspension structure (ceiling, beams or a standalone structure) and on the spacing between brackets. Standard beef installations usually work with loads of 250 to 350 kg per trolley, and the 18 mm stainless hook is designed for beef carcasses up to 350 kg. We help you size your installation.

Which trolley or hook do I need for pork, beef or lamb?

For pork, the trolley with a 15 mm hook or a 600 mm V gambrel; for beef, the 18 mm hook; for lamb, the 12 mm hook, the 400 mm V gambrel or pendants, which carry several pieces on one trolley. For cuts there is the hanger for cuts.

Can it be adapted to the shape of my building or cold room?

Yes. With 45° and 90° curves (360 mm radius), single, double and triple switches and brackets anchored to the existing structure, the rail network fits almost any space. We carry out the preliminary study, the route drawing and the 3D structure design, and we manufacture the rail ourselves.

How are carcasses loaded onto the truck?

With swing-tilt arms for coupling to trucks, with twin track rail for the truck itself, or with hydraulic loading arms: the dock arm loads up to 300 kg and the truck arm up to 150 kg.

Can carcass handling be automated?

Yes. The automatic conveyor for twin track rail moves carcasses continuously, with sensors and programming to control the operation, and its modular design adapts to each installation. A continuous chain elevator is also available.

Can I buy individual parts or spares?

Yes. Rail, brackets, curves, switches, trolleys, hooks, pendants, hangers and arms are available in our online shop, tiendabernad.com. If you are not sure which part you need, call us on +34 967 219 649 or write to us.
