Medium Plastic Pulley with Steel Ring

Product Overview

The medium pulley is a compact lifting wheel for poultry house winch systems, shown in blue and red wheel versions, each 8.5 cm tall and weighing 36 g. A galvanized steel ring at the bottom links the pulley to the rope or line, while the white plastic body holds the wheel. The blue and red colors let farms code different rows or functions on the same ceiling.

At half the height of the large yellow pulley, this medium version suits light to medium winch loads, such as shorter drinker rows, breeder pen lines and ventilation cable guides. The steel ring gives a solid attachment point that plastic eyes alone would not provide.

Key Features and Benefits

• Medium 8.5 cm size - suits light to medium winch loads where a large pulley is unnecessary.
• Blue and red wheel options - color-code rows or functions on the same ceiling system.
• Galvanized steel ring - strong attachment point for the rope or line, resisting humid house air.
• 36 g light body - adds little load to the winch system it serves.
• White plastic housing - protects the wheel axle while blending with other white fittings on the line.
• Free-rotating wheel - turns smoothly so the winch rope glides instead of dragging.

Materials and Quality

The wheel is molded in blue or red engineering plastic chosen for low rope friction and dust resistance. The white housing holds the axle, and the bottom ring is galvanized steel so it does not rust in the humid house air. Each pulley is checked for free wheel rotation and a firm steel ring before packing.

The blue and red colors are molded into the wheels, so the coding stays visible after years of use. We keep both color versions produced to the same 8.5 cm size and 36 g weight, so a farm can swap between them without changing mounting hardware.

The wheel runs on a simple bush pressed into the white housing, and the galvanized ring is looped through the housing base so the load pulls straight rather than twisting. Blue and red wheels share the same molding except for the tinted resin.

How to Use and Maintain

Fix the pulley housing to the ceiling support, thread the winch rope around the wheel, and clip the steel ring to the line or cable that needs lifting. Check that the wheel spins freely before the first lift of the season.

Once a season, inspect the wheel for cracks and the steel ring for rust, and grease the axle lightly if rotation feels stiff. Replace the pulley if the wheel cracks or the ring loosens, and keep a few spares of each color in the farm toolbox so repairs match the row coding.

Hang the housing on the ceiling anchor, clip the steel ring to the lifting cable, and lead the rope over the wheel. Keep blue wheels on one house section and red on another so staff can trace which rope runs to which winch.

Applications

This medium pulley is used on lighter winch systems in layer houses, breeder pens and small broiler rows, where the lifting load sits between a small and a large pulley. It also serves ventilation cable guides and curtain lifting on medium-duty runs.

It is popular on farms that color-code rows, using blue for one house section and red for another. Distributors stock both colors together so a dealer can supply a full color-coded lifting system from one order.

Small breeder houses and poultry fancier farms use the medium pulley where a large yellow wheel would be overkill. The color coding also suits integrators managing several houses, letting them identify rows at a glance during maintenance.

Frequently Asked Questions

Q1: What is the difference between the blue and red versions?

They are the same 8.5 cm, 36 g pulley in different wheel colors; use color to code rows or functions on the ceiling.

Q2: How heavy a load does it carry?

It is built for light to medium winch loads; choose the large yellow pulley for heavier drinker lines.

Q3: Is the bottom ring steel?

Yes, it is a galvanized steel ring that resists the humid poultry house air.

Q4: Can I mix colors on one house?

Yes, blue and red pulleys can be mixed across rows according to your color coding plan. Tell us which house sections you want in blue and which in red, and we will pack the two colors to your split. Each unit weighs 36 g and hangs 8.5 cm tall, fitting tight ceiling spots where the large yellow pulley will not go. Send us a sketch of your ceiling anchors, and we will confirm the steel ring hanging method suits the load. Blue and red wheels let crews tell rows apart from the ground without climbing to read a label. A quick tug on the steel ring each season confirms it is still seated in the housing before the line is lifted. Keep one blue and one red spare on the maintenance board so a failed pulley can be swapped without losing the color code.
