Astrak's Exchange Track Group service is a cost-effective alternative to full track group replacement. An equivalent track shoe, matched to the same wear level as your existing set, is fitted to brand new chains, assembled in the Astrak workshop in Kirkcaldy, and delivered direct to site.
The service allows you to keep working with your current equipment up until changeover, with a fast, efficient swap that maximises machine uptime. Fitting can be completed in the workshop or on site by Astrak plant fitters.
The programme is available for 13- and 20-tonne excavators, with all work completed to OEM specification.

Safe pallet preparation & returning to Astrak
To meet our safety responsibilities to staff, logistics partners and customers, all returned track groups must be palletised in a safe, transportable manner.
Tracks must be rolled and strapped to the pallet (see figure 1), using two straps: one around the rolled track and one over the top, securing it to the pallet.
If a ratchet strap is required, please advise Astrak at the point of initial contact so one can be dispatched with the track group delivery. Ratchet straps will not be sent unless requested.
Our logistics partners reserve the right to refuse collection where a track group is deemed unsafe or dangerous to transport (see figure 2). Astrak reserves the right to pass on a failed collection charge to the customer in these instances. Please contact us for current charge details.
To support environmental obligations and improve turnaround times, please make every effort to remove excess dirt before returning exchange track groups. We understand this is not always possible given that tracks are often removed and fitted on site. However, where track groups are returned with excessive rubble or cement, an additional charge may be applied to cover the extra strip-down time required before reassembly.


Terms & Conditions
This agreement between Astrak and the customer is subject to the following actions being agreed and acted upon:
- Order pricing is confirmed in the form of an accepted quotation.
- Goods received are as per the accepted quotation.
- Astrak receives the goods return within 5 days of new track groups being delivered to the customer.
If the 5-day period is not achievable by the customer, Astrak must be informed in order for us to plan effectively for future assemblies. Failure to do so may result in additional charges.
Astrak will provide this service in good faith and agree a selling price based on the assumption that we receive the used track shoes at the agreed grouser height.
Should Astrak receive used track shoes at a lesser height than the agreed grouser height, Astrak reserves the right to:
- Recoup monies by passing on a charge to cover the difference in cost between the agreed track shoe grouser height price and the cost of what is received.
- Refuse the track shoes received and cancel the agreed works. In this instance, Astrak will provide photographic evidence to the customer to demonstrate what has been received, using the required measuring equipment.
Furthermore, Astrak reserves the right to credit the customer the price of goods, less the cost of the reverse transport.
Should returned track groups be deemed to have excessive amounts of rubble/cement, Astrak reserves the right to apply a charge, due to the extra time to strip these and ready them for a new assembly.
Astrak is entitled to apply a failed collection charge should goods be deemed unsafe or dangerous to transport. This will be advised at the point of collection by our logistics partner and costs will be incurred.
