Pulley bars Anti-skid for conveyor head pulley
Pulley barsⓇ have a robust design and are made from wear-resistant rubber for long life. Anti-skid bars are very useful on inclined conveyors and elevators. The bars are fastened to the drum using self-tapping screws, a process that simplifies and speeds up the replacement of worn bars.
Built for rugged durability, drum pulley bars are made from tough, nylon-reinforced polyester with a diamond surface pattern to deliver proven performance. Lagging with Pulley BarsⓇ is easy to install: no special tools are required. This lagging is also easy to maintain. The design uses a simple fastening system to replace the drum lagging. This feature reduces installation time, as there’s no need to remove the belt from the drum.

Other profile types
Diamond
The universal lagging
Used on bend pulley and take up pulley. It is also suitable for head pulley.
Ceramics
The high-adhesion lagging
Effective in humid environments to prevent slipping on the conveyor belt.
Smooth
Protective lagging
For conveyor pulleys that don’t drive the belt, to extend their service life.
Slide Lag
For high tensile forces
Its elastomer composition gives drive or head pulleys high tensile strength.
Griplag
For tough conditions
The Griplag prevents slippage and is self-cleaning, preventing material build-up and misalignment.
VARIOUS LAGGING AND PREPARATIONS
Hot vulcanization
Vulcanisation is a chemical process that gives the drum pulley lagging greater tensile strength, swelling, abrasion resistance and elasticity.
Cold rubberising
Cold rubber bonding is generally used on "classic" drum pulleys for rubber coatings with smooth, diamond-shaped ceramic inserts.
Special rubberizing
Coatings such as Slide Lag, Pulleybars or Griplag are applied to conveyor drums and conveyor pulleys by mechanical assembly.
Shot-blasting
All coated conveyor pulleys are shot-blasted for improved surface preparation. This preliminary work is essential for optimum adhesion to the conveyor belt pulley.
