Spare Parts & Technical Service

In heavy industry, an unexpected line stop can cost thousands of dollars per hour. Lost production, customer contract penalties, overtime and rushed spare-parts purchases are the main components of that cost.

TMD GRUP's spare parts and technical service is designed to reduce both the frequency and duration of these stops. Because the line is TMD-manufactured, we know the characteristics, critical points and endurance limits of every component as the manufacturer; unlike third-party service providers, we can perform root-cause analysis directly and propose lasting solutions.

TMD GRUP keeps the spare parts used in its customers' lines at its Ankara-based stock depot. The stock covers the following categories:

• Fast-moving parts — bearings, seals, belt pencils, bucket bolts and similar items replaced at regular intervals.

• Critical parts — motors, gearboxes, helices and similar items that rarely fail but stop the line when they do.

• Wear parts — belts, helices, valve seals and similar items that wear by design.

When a customer request comes in, in-stock parts can be shipped the same day or the next; items requiring special-order production enter the production priority queue.

Reactive maintenance (intervention after failure) is the most expensive approach. TMD GRUP's periodic maintenance contracts ensure the transition from reactive to proactive mode:

• Monthly / quarterly / semi-annual visits — determined by the line's operating hours.

• Standard check points — bearing temperatures, motor currents, belt and bucket conditions, seal integrity.

• Oil and oil-filter change schedule.

• Wear-part replacement plan — scheduled replacement before failure.

• Maintenance report — documented status and recommendations after each visit.

This approach extends line life and reduces unexpected stops by 60-80%.

Modern industrial lines are now equipped with sensors: vibration sensor, temperature sensor, motor-current monitor, belt-speed sensor, etc. When this data is correctly analysed, it shows the signs of failure days in advance.

TMD GRUP's IoT monitoring package:

• Sending sensor data to cloud servers.

• Automatic detection of abnormal changes (threshold crossing, trend analysis).

• Daily review at the TMD engineering office.

• Proactive notification to the customer for risk situations — "this bearing may cause issues within 2 weeks, replace it".

This approach prevents unexpected stops and ensures production continuity.

A production line stops regardless of whether it is a holiday, night or weekend — so technical support must not have time limits either. TMD GRUP provides a 7/24 technical support line:

• First response by phone and remote connection (TeamViewer, AnyDesk, etc.) — most problems can be solved remotely.

• Field engineer dispatch — for situations that cannot be solved remotely, on site within 24 hours per contract.

• Emergency spare-parts shipment — same day if the part is in stock, in the priority queue if production is required.

• Post-resolution root-cause analysis — additional preventive recommendations to ensure the same problem does not recur.

This rapid-response structure ensures we are there for the customer in moments of crisis.

Each customer's needs are different: some only need emergency support, others prefer a full-scope maintenance contract. TMD GRUP offers flexible SLA (Service Level Agreement) models:

The long-term benefits of spare-parts and technical-service offerings are twofold:

1. Cost predictability: with an SLA contract, monthly or annual maintenance costs are fixed; no surprise large expenses.

2. Long line life: thanks to preventive maintenance, a TMD GRUP line can operate beyond its design life; this increases the return on investment.

The initial manufacturing-installation phase is critical, but the line's reliable operation over the years is equally important. The TMD GRUP technical service team is the provider of this long-term trust.
