what we do

The solution

that fits your needs

At Starkon, we support Cranes with skilled Technicians and specialized Rail & Wheel Services. From Inspections and preventive maintenance to Wheel Overhauls, Rail Alignment and structural Repairs — we reduce pressure on your Technical Department and keep your Operations running.

At Starkon, we specialize in the complete replacement of Trolley Rails, including both Block Rail and A-Profile Rail Systems.

After a certain number of operating hours, Trolley Rails typically develop wear-related issues as vibrations and increased maintenance requirements. While replacement is major intervention, Starkon has made this its core expertise.

We carry out Trolley Rail Replacement using economically efficient methods, ensuring minimal downtime and maximum safety. Our approach goes beyond simple replacement — we address the entire Rail System during execution.

Scope of work

  • Complete Replacement of Block Rail and A-Profile Trolley Rails
  • Rail Pad Replacement
  • Rail Bed Repair and Correction
  • Alignment of the new Rail System
  • Weld Repairs where required

At Starkon, we carry out complete trolley truck overhauls to restore the performance of bogies and wheel assemblies. Due to continuous operation under high loads, trolley trucks are subject to wear, misalignment, and bearing failures. Our overhaul approach ensures all critical components are restored to original condition, fully in line with applicable standards.

Function

By overhauling the complete trolley truck system, we:

  • Inspect bogies, wheel assemblies, and structural components
  • Replace worn bearings and critical parts
  • Restore wheel geometry and alignment
  • Detect defects that may affect crane performance

Our Strength

  • In-house welding and machining of bearing housings and bores
  • Thermal cutting and removal of shafts in-house
  • Full overhaul capability without dependency on third parties
  • All required disciplines available under one roof
  • Precision alignment using total station equipment

At Starkon, we replace short rails in a safe and efficient manner. Our team has many years of experience in executing these replacements, ensuring precision and reliability. Even with proper maintenance, short rail replacement is unavoidable during a crane’s lifetime.

We typically complete this work within a maximum downtime of 10 days, delivering results that exceed OEM quality by combining the replacement with our own high-grade components.

Why replace on time?

Timely short rail replacement not only improves operator comfort but also protects and extends the lifetime of other critical components, such as trolley wheels.

With Starkon short rail replacement, clients benefit from minimized downtime, enhanced quality, and longer overall crane performance.

At Starkon, we carry out precise trolley rail surveys to measure both the rail and its supporting structure, including the detection of soft spots. Because trolley rails are often difficult to access, we have developed a dedicated method that makes inspections more efficient and measurements more accurate, fully in line with NEN/DIN standards.

Function

By surveying the complete rail system, we:

  • Measure rail alignment and supporting profiles
  • Identify soft spots and potential weak points
  • Detect deviations that may affect crane operation

Key Benefits

  • Accurate measurement according to NEN/DIN standards
  • Efficient inspection method for hard-to-access areas
  • Detailed insight into rail condition and alignment
  • Early detection of risks to prevent costly downtime
  • Clear reporting for maintenance planning and decision-making

By combining advanced survey methods with practical reporting, Starkon provides clients with a reliable overview of rail condition and dimensions, ensuring safer and more efficient crane operations.

At Starkon, we conduct professional trolley rail vibration measurements in compliance with current standards for operator exposure and machine safety, including EN ISO 5349-1/2 for hand-arm vibration and ISO 2631-1 for whole-body vibration, as incorporated in the EU Directive 2002/44/EC.

Function

Using certified vibration measurement equipment, we:

  • Measure operator exposure to vibration, both in handles and seat, ensuring compliance with legal limits
  • Identify critical vibration hotspots along the rail that require attention or maintenance

Key Benefits

  • Adherence to recognized vibration exposure standards (EN ISO 5349-1/2, ISO 2631-1)
  • Efficient inspection—even in difficult-to-access rail systems
  • Early detection of problematic zones for precise maintenance planning
  • Accurate data to support operator safety and crane reliability

By combining advanced measurement tools with expert analysis, Starkon offers clients clarity on vibration exposure and targeted insights to optimize safety and crane performance.

At Starkon, we specialize in engineering solutions tailored to resolve complex trolley rail challenges—such as improving rail transitions, reinforcing foundations, and optimizing component selection when existing systems fail.

Engineering solution

What we offer:

  • Engineering design for improved rail transitions or foundations
  • FEM and deformation analysis for rail components and support beams
  • Customized component selection (rails, clips, sole plates) based on failure analysis
  • In-house fabrication of tailored solutions where standard approaches fall short

By combining deep rail replacement experience with advanced engineering and bespoke fabrication, Starkon delivers durable, optimized rail systems that resolve root causes and enhance operational performance.

At Starkon, we service and optimize trolley tensioning systems as an essential part of the overall crane rail and trolley performance.

The correct functioning of the trolley rail and trolley system depends heavily on proper tensioning. Over time, these systems can lose accuracy, leading to misalignment, increased wear, and operational issues.

Our team has developed strong expertise in the repair, adjustment, and modification of trolley tensioning systems, ensuring reliable and stable operation. All work is carried out with a focus on safety, precision, and long-term performance.

Why proper tensioning matters

Correctly functioning tensioning systems improve trolley tracking, reduce wear on wheels and rails, and prevent unnecessary stress on the crane structure. With Starkon trolley tensioning services, clients benefit from improved system stability, reduced maintenance, and optimized crane performance.

At Starkon, we service and supply trolley and gantry wheels as an essential part of overall crane performance. The correct functioning of both trolley and gantry systems depends heavily on the condition of wheels and bearings. Over time, wear can lead to misalignment, increased vibration, and operational issues.

Our team has developed strong expertise in the refurbishment and replacement of wheels and bearings, as well as the supply of new wheel sets. All work, including disassembly and assembly of wheels, is carried out safely on-site with a focus on precision and reliability.

Why wheel condition matters

Well-maintained wheels and bearings ensure smooth crane travel, reduce wear on rails, and prevent unnecessary stress on the crane structure. With Starkon wheel services, clients benefit from reduced vibration, extended component lifetime, and reliable crane operation.
