Heavy Engineering & Reclamation Specialists

Baker & Provan Capability

• Heavy Engineering – Reclamation Specialists

– Machining,

– Fabrication,

– Assembly / test

Reclamation Examples• Examples of jobs that are considered unrepairable or difficult to repair, such as cast iron castings or damaged gears

• jobs include cast iron repair utilising various cold repair techniques

• Cold repair techniques eliminate distortion to castings and gears

Rail Car Diesel engine cast iron risers frequently crack – repaired

Gear wheel with extensive damage – repaired

Aluminium casting modification

Damaged – Replicated to spec and much stronger component

Rail brake cylinders – bore repaired with metal spray. Broken feet/mounting holes repair without welding

Build Up & machine

Impeller repair – bore had picked up on shaft

High temperature valves – weld and machining repair of valves, paddles & tubes

Cast Iron bore Repair - low temp welding

Gear Segment – low temp repair

Cold Repair Technique

No Welding

Leakage between stages – build up and machine

Bogie repair – cast iron casting where centre ring undersize – successfully repaired, no welding

8m Cast Iron Casting – cold repaired

Stainless steel thread stripped – repaired without welding

Bearing and bore metal spray failure – repaired without metal spray and without welding

Loco diesel engine heads – typical cracks that are repaired using procedures to Lloyds specifications

Cast Iron Housing – cold repair process

Cracked Casting – cold repair, no welding

SS Casting – repaired without welding

Broken feet / mounting positions – can be repaired

diesel engine heads – typical cracks that are repaired using procedures to Lloyds specifications

Cast iron engine head – crack repaired

Identified mode of failure, developed repair solution

Loco diesel engine oil pump housing bores oversize – repaired without welding, significant saving
