Heavy Duty Mechanic

Duty Mechanic Jobs in Doha – Job Overview

QD-SBG Construction is seeking a Heavy Duty Mechanic in Qatar for its plant, machinery and vehicles (PMV) and maintenance team supporting construction operations. The role is in Doha, with the workplace listed as Al Daayen, Zone 69, Doha. The notice focuses on vehicle and heavy equipment maintenance and repairs within construction, alongside troubleshooting and technical skills.

Job description

In general heavy equipment maintenance, work starts with a clear fault report. The following workflow describes normal trade practice, rather than additional employer requirements. The mechanic identifies the vehicle or machine and asks when the problem occurs. Next, the operator explains any unusual noise, warning light or change in performance. Service records help show whether the fault follows earlier repairs or overdue maintenance. Before testing, the mechanic checks whether the equipment can move safely. If it cannot, the supervisor needs that information before anyone plans further use. This first check helps separate an urgent safety fault from a routine service need.

Before hands-on work, the mechanic checks the equipment manual and the planned repair area. Heavy machines can hold pressure or move even after the engine stops. So the mechanic follows safe isolation steps and checks that raised parts have support. Hot fluids, stored hydraulic pressure and heavy components each need suitable handling controls. The mechanic also checks access around the machine before removing covers or guards. If access creates a risk, the repair plan must change before work starts. Suitable lifting support matters because a loose component can shift during removal. Preparation should protect both the mechanic and nearby workers.

Checks and exception handling

For a typical diagnostic example, consider a machine that overheats only under load. The mechanic first confirms when the temperature rises and checks the operator's account. Once the engine cools, coolant level, visible leaks and radiator condition provide useful clues. However, a full coolant tank does not prove that the cooling system works properly. The next checks may cover airflow, belt condition and coolant circulation, following the manual. Recorded temperatures help distinguish a cooling fault from an incorrect warning signal. If the cause remains unclear, the mechanic reports the findings instead of guessing. The supervisor then knows why the machine needs further checks before return to work.

After diagnosis, the mechanic defines the repair scope and checks the correct replacement parts. A part that looks similar may have a different pressure rating or connection. Therefore, equipment identification and part details matter before fitting begins. During removal, the mechanic protects open lines and keeps dirt away from internal parts. Clean assembly helps prevent a new fault after the original repair. The mechanic follows the specified tightening values and adjustment steps rather than relying on feel. If inspection reveals further damage, the person approving the work needs an updated repair scope. This avoids completing only part of the necessary repair.

Coordination and completion

Repair completion does not by itself show that equipment is ready for use. The mechanic first checks fluid levels, connections, guards and the work area. Then a controlled test checks whether the repaired system responds as expected. The test should match the original complaint without creating an unsafe operating condition. Readings and observations give a clearer result than a brief engine start alone. If the fault returns, the mechanic stops the test and reviews the diagnosis. Any separate defect also needs a clear record and a decision about safe use. The responsible supervisor needs the result before arranging the machine's return.

The listing also the mechanic records the fault, checks completed, parts used and test results. Clear repair notes help the next person understand what changed and what remains unresolved. The operator also needs simple information about any symptoms to watch for. Meanwhile, the maintenance planner needs details of work that still requires parts or access. Repeated faults can point to a wider issue, but records must support that conclusion. For this reason, notes should distinguish measured results from possible causes. A useful handover states the equipment's condition without making promises beyond the checks completed. This closes the repair record and supports later maintenance decisions.

Typical Duties & Responsibilities

• Check service intervals against equipment records and flag tasks that have reached their scheduled due point.
• Inspect tyres, tracks and undercarriage wear, and identify damage that could affect movement or stability.
• Examine brakes and steering for wear or poor response, and report defects that affect vehicle control.
• Trace fluid leaks to their source and distinguish fresh leakage from old residue before planning repairs.
• Measure battery and charging performance against technical limits to identify weak electrical supply or charging faults.
• Check hoses and fittings for rubbing, cracks or loose connections before these develop into larger failures.
• Separate damaged reusable parts from serviceable items so later assembly does not reintroduce a known defect.
• Keep used oil and removed materials in suitable containers to reduce spills and contamination around repairs.

Candidate Profile

As application preparation, choose a repair you personally completed and can explain clearly. For example, describe how you found an intermittent starting fault on a construction vehicle. State which readings you took, what they showed and how you confirmed the repair. Be clear about your own work and any help from other technicians. Use only records you have permission to share, without confidential project details. Also ask about the equipment fleet, workshop and site coverage, and employment arrangement. These questions help clarify conditions beyond the advertised requirements.

Qualifications & Requirements

• Experience: 5 Years; Proven experience in vehicle and heavy equipment maintenance and repairs; Experience within the construction industry.
• Preferred: Available for immediate joining
• Preferred: Holding a transferable visa
• 5 years of experience.

Employer-stated Skills & Competencies

• Strong troubleshooting and technical skills
