Expander System – a Time Saving Repair Solution for Construction Machinery

Описание: Delvator, the general agent for Hitachi’s construction machinery in Sweden, uses Expander System to avoid line boring and welding, eliminate lug wear and reduce repair time for customers.

"We save time for ourselves and above all for the customer. Expander System is a simple solution to a big problem", says Thomas Johnsson, After Market Manager.

Expander System is used out in the field or in workshops, as a direct replacement for worn traditional straight pivot pins.

If a machine has rotational movement, it has pivot joints. Unfortunately, with traditional axle pins, tolerance is inevitable and will deform the lug bore over time. This lug wear ruins the precision of machinery and eventually requires maintenance downtime. We know that time is money, and every day an excavator, wheel loader, or crawl excavator sits in a workshop for repair, that’s an operational cost to its owner.

Expander System is a permanent solution to lug wear repair that is fast and easy to install and remove. Using only basic hand tools, repairs can be carried out directly in the worn bores without the need for welding and line boring. Because of the expanding sleeves that conform to the bore wear pattern, the problem is eliminated for good – hence thousands of machine owners and workshops worldwide have already switched to Expander System.
