UNDERCARRIAGE MANAGEMENT 

Customer Track Service (CTS) 

Poorly managed undercarriage systems account for more than half of machine maintenance costs. Using Custom Track Service (CTS) diagnostic equipment can save your business downtime and help reduce operating costs. 

CTS accurately monitors undercarriage performance to predict wear rates, so you can make informed choices about service plans, maintenance schedules and parts replacement. Even better, a Hastings Deering specialist will visit your job site to complete a full CTS inspection, so there’s no need for your machine to be out of action for long periods of time.  

Talk to us today to book your CTS inspection.
