• Dismantle, repair, replace, and reassemble defective mechanical components and equipment.
  
• Maintain accurate records and logs of inspections, maintenance activities, repairs, and equipment performance.

Plant Assembly and Commissioning

• Participate in the mechanical assembly, commissioning, mobilisation, and dismantling of cranes, excavators, drilling rigs, and other heavy construction plant.
  
• Support the installation and setup of construction equipment for site operations.
  
• Assist with the assembly, testing, maintenance, and dismantling of auxiliary equipment including pumps, batching plants, and associated systems.
  
• Ensure all mechanical works are completed safely and in accordance with company procedures and manufacturer requirements.

Mechanical Servicing and Repairs

• Perform mechanical servicing and repairs on cranes, excavators, drilling rigs, pumps, and other heavy construction equipment.
  
• Carry out preventative maintenance on smaller plant, tools, pumps, and ancillary equipment.
  
• Diagnose mechanical faults and identify appropriate repair solutions to minimise equipment downtime.
  
• Carry out repairs and component replacements using appropriate tools and equipment.
  
• Read and interpret technical manuals, maintenance documentation, equipment drawings, and manufacturers' instructions.
  
• Support continuous improvement initiatives focused on plant reliability, maintenance standards, and operational efficiency.

Operational Support and Safety

• Support the safe operation and maintenance of heavy construction plant in both workshop and site environments.
  
• Adhere to all health, safety, environmental, and quality requirements.
  
• Work closely with supervisors and operational teams to ensure equipment remains available and fit for purpose.
  
• Maintain accurate maintenance records and provide regular updates to the Plant Supervisor.
  
• Undertake additional duties as reasonably required to support operational and project needs.

Candidate Profile

Education & Experience
