ALTEMA know-how for easy maintenance of conveyor drums
Laggings, such as Slide LagⓇ, PulleybarsⓇ or GriplagⓇ, are applied to conveyor pulleys by mechanical assembly. Their special feature is that they are interchangeable without having to remove the drum pulley from the conveyor.
GriplagⓇ is a lagging that absorbs the movement between drum pulley and belt caused by belt stretching. Griplag keeps belts cleaner, reducing costs and downtime due to breakdowns.
PulleybarsⓇ anti-slip bars are designed to enable materials to be transported on inclined conveyors or elevators. They can be used on reversible conveyors.
The Slide Lag® lagging uses thick steel plates designed to fit every drum diameter. Its unique elastomer composition gives head or drive drums high tensile strength and prevents flange and roller wear.

Profile types
Diamond
The universal lagging
Used on deflection 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 head or drive pulleys high tensile strength.
Pulley bars
Anti-skid lagging for large drums
Ruggedly designed, the anti-skid bars are made of wear-resistant rubber for long life.
Griplag
For tough conditions
The GriplagⓇ prevents slippage while being self-cleaning, preventing material build-up and misalignment.
The benefits of rubber lagging
- Bonding systems that make installing pulley rubber easy, fast and tailored to your needs.
- The lagging protect the belt and significantly improve the conveyor’s overall performance, thus extending its service life.
- They ensure that rollers and drum pulleys rotate smoothly without clogging, thus maintaining and aligning the conveyor belt.
- Rubberized pulleys protect the belt by reducing slippage between belt and pulleys.
- They reduce the belt’s operating tension, thus reducing belt elongation.
- They reduce conveyor noise and vibration.

Different laggings and preparation
Hot vulcanization
Vulcanisation is a chemical process that gives the drum greater tensile strength, swelling and abrasion resistance, as well as greater elasticity.
Cold rubberizing
Cold rubber bonding is generally used on “classic” drum pulleys for rubber coatings with smooth, diamond-shaped ceramic inserts.
Shot-blasting
All coated pulleys are shot-blasted for improved surface preparation. This preliminary work is essential for optimum adhesion to the conveyor belt pulley.
