Australian Manufacturing Excellence

Lagging for Caterpillar turbos, manifolds & exhaust pipes

  • Comply with safety standards and mitigate fires
  • Keep Cat exhaust surface temperatures below fuel ignition points
  • Protect maintenance crews from extreme burns
  • Easy to install and remove
  • Designed to fit Caterpillar machines like a glove
  • Shield Cat heat-sensitive components from hazards (eg. high-voltage lines)

Our top priority is protecting your crew from burns and shielding hot surfaces from causing fires. Caterpillar engine and exhaust-related fires are preventable with thermal insulation blankets.

Strategic benefits of Aletek blankets for CAT Mining Equipment

  • Mitigate engine fires on Caterpillar mining assets
  • Protect your workers from fire and burns
  • Access engine bays sooner with a shorter cool-down time
  • Designed and crafted in Australia
  • Reduce engine fires, site shutdowns and insurance premium hikes

Exhaust Blankets tailor-made for Caterpillar machines

Aletek engine insulation blankets offer unsurpassed fleet protection. Our Caterpillar exhaust lagging solutions can protect your crew and assets while reducing fire risk. For a comfortable fit and optimal fire protection, our products include the following attributes:

  • Reduce surface temperatures below fuel ignition points with exhaust blankets
  • Lobster-back design to prevent debris and flammable liquid ingress
  • Quick-fit springs pre-installed for faster installation
  • Easy to install, snug-fitting and non-itch

As a result of our attention to detail and a glove-like fit, exhaust parts operate at lower temperatures to safeguard your Caterpillar engines.

Machine-specific Solutions

Insulation blanket kits for Caterpillar

Align your asset-specific fire strategy with blanket kits to suit engine groups. For example, you may specify turbo, manifold, engine pipe, and muffler blankets for Caterpillar dozers. Blanket kits are also available to replace damaged lagging.

Turbo & junction blankets for Caterpillar

Thermal blankets for turbos and junctions are a vital protective measure against extreme temperatures. In the event of a fuel leak, higher temperatures increase the fire risk. Aletek blankets are snug-fitting and have quick-fit springs to facilitate removal.

Manifold blankets for Caterpillar

As with turbos, manifolds also generate substantial heat. Insulate manifolds with Aletek’s impenetrable, multi-layer blankets to reduce surface temperatures below flashpoints. Install manifold lagging carefully to ensure a snug fit and adequate coverage.

Engine pipe blankets for Caterpillar

Engine pipe blankets provide additional protection against engine fires. We recommend lagging pipes near high-voltage lines for electric drive assets such as Cat 794 AC. You may consider exhaust system blankets for zones near fire hazards, such as grease pumps and junctions.

Muffler & tailpipe blankets for Caterpillar

Muffler and tailpipe blankets are popular additions to compact engine bays, such as those found on Cat D10T and D11T dozers. Muffler blankets may be necessary to fix radiant heat issues near a driver’s cabin. Aletek blankets are custom-made to suit each component of Caterpillar engines.

Lagging for Caterpillar Dozers

We tailor our thermal blanket packages to suit Caterpillar dozers. Our line-up covers models from Cat D6 to D11T. We offer turbo wastegate covers with our D11T lagging kits for additional fire protection.

Lagging for Caterpillar Excavators

Add Aletek blankets to your Caterpillar excavators to improve fire safety. We have engine lagging solutions for 305.5E2 Mini excavators up to 6060 hydraulic mining shovels. Our signature glove-like fit is backed by quality Australian manufacturing.

Lagging for Caterpillar Graders

Want to protect your Caterpillar motor graders from engine fires? We provide blanket kits that shield engine components such as turbos, manifolds, pipes, mufflers and tailpipes. Thermal blankets are available for Cat 140H to 160 graders and 12H to 24M graders.

Lagging for Caterpillar Haul Trucks

Creating thermal blankets for Caterpillar haul trucks is what we do best. With Aletek blankets, you can protect the entire exhaust pipe setup, including the bellows. We improve our designs through a continuous feedback loop. We offer lagging kits for Cat 725 to 797F trucks.

Lagging for Caterpillar Wheel Loaders

Aletek creates thermal insulation products for single- and dual-engine Caterpillar wheel loaders. Make sure your loaders are fireproof from manifold to muffler. We offer blanket kits for Cat 924K through to 994K models.

Other Caterpillar Assets

If it has a Caterpillar badge, there’s a good chance we can lag it. In addition to drills and compactors, we manufacture blankets for scrapers and wheel dozers. We’ve heard many success stories from maintenance crews who use our drill rig blanket kits to prevent nasty burns.
