Inspect & define
Share crane details, the reported issue, photographs and drawings. We establish the inspection or repair scope with your team.
STARKON / CRANE SERVICE
Crane Service
Rail, wheel and mechanical expertise. From inspections and planned maintenance to complete crane overhauls.
Discuss your requirementsMAINTENANCE / REPAIR / OVERHAUL
Practical expertise. At height and on the ground.
Our teams work on port cranes, rail systems and trolley assemblies. We connect inspection, engineering, workshop preparation and on-site execution around your operational window.
Trolley rail replacement
Complete replacement of block rail and A-profile trolley rail systems. We assess the rail, its fastening and the supporting rail bed together to address wear, vibration and poor trolley travel.

Short rail replacement
The rail transition at the boom hinge needs close attention. We manufacture and install replacement short rail components, checking the support, transition geometry and alignment as part of the repair.

Trolley truck & bogie overhaul
Trolley truck overhaul brings wheels, shafts, bearings and the supporting steelwork into one repair scope. Inspection findings determine which components can be retained and which need repair or replacement.

Crane vibration analysis
Vibration during trolley travel can be a sign of a rail transition, wheel or support problem. STARKON investigates crane vibration and operator-reported movement to help identify where corrective work will have the greatest effect.

Crane rail survey & alignment
A rail survey gives the maintenance team a clearer picture of the running path and its supports. We measure the rail geometry and investigate local irregularities before recommending adjustment or replacement.

Trolley tensioning systems
We inspect and repair main and auxiliary trolley tensioning systems. Arms, shafts, sheaves and hydraulic cylinders are assessed as an assembly, with workshop preparation coordinated around the on-site work.

Trolley & gantry wheel replacement
Worn wheels and bearings can affect travel and increase the load on adjacent components. We combine replacement wheel sets with inspection of the mounting arrangement and alignment of the installed assembly.

Rail pad replacement
Rail pads are part of the complete rail support system. We plan their replacement together with access, controlled rail lifting and the condition of the rail bed and clips.

Rail clip maintenance
Loose, damaged or unsuitable rail fastenings can allow movement and uneven loading. Our teams inspect and replace rail clips and associated components to the confirmed rail-system specification.

Rail bed & shear block repairs
A replacement rail needs a sound foundation. We investigate worn or damaged rail beds, soleplates and shear blocks, then define the welding, machining and support repairs needed before the rail is reinstated.

Crane rail engineering
Engineering connects a measured problem to a buildable repair. We support rail and transition work with geometry review, component drawings and structural analysis appropriate to the agreed scope.

Access platforms for rail work
Suitable access helps the team work effectively along a crane rail. We supply and use access platforms tailored to the girder and crane arrangement, with the installation and operating method defined for the task.

Crane sheave replacement
Sheave maintenance involves more than the rope groove. We check the shaft, bearings, covers and mounting arrangement, and coordinate component supply with removal and installation on the crane.

Mechanical & structural crane repairs
Practical repairs to crane mechanisms and supporting steelwork combine inspection, engineering and experienced site execution. We agree the repair scope and work sequence around the condition of the crane.
Explore this service ↗
Thermal lancing & seized shaft removal
Thermal lance cutting for seized crane shafts and pins. We assess the assembly and access, plan the removal and inspect the retained components before reassembly.
Explore this service ↗
On-site machining — line boring & milling
On-site line boring and portable milling for crane bores, rail supports and mating surfaces. We bring machining to the component where access and the repair scope make this practical.

IN PRACTICE
Rail work, from component to installation.
In 2022, STARKON produced, supplied and installed short rail components for eleven STS cranes. The work connected component preparation, support alignment and on-site installation.
View the rail projectA PRACTICAL WORKING METHOD
Plan the scope.
Prepare the work.
Your crane, the condition of its components and the available maintenance window determine the approach.
Prepare & coordinate
Component supply, workshop work, access and on-site activities are coordinated before execution.
Execute & hand over
We carry out the agreed work and document the findings and completed scope for your maintenance team.
