Geometry and surveying
Checking rail alignment, levels and the relative position of the two rails. Measurement identifies deviations from the required condition and provides a basis for planning the repair.
DLD SERVIS · CRANES AND CRANE RUNWAYS
Crane runway service and alignment
Impacts at rail joints, clips working loose, uneven wear or a crane that skews during travel. These symptoms call for assessment of the runway together with the crane. DLD Servis provides crane runway surveying, alignment and repairs, from checking geometry to rail replacement and work on rail support arrangements.

We assess the complete runway
Crane runway alignment and levelling
Runway alignment corrects the horizontal and vertical position of crane rails based on a survey and the required geometry. Before adjustment, we assess the rail clips, supporting surfaces and structure. Rails are repositioned within the limits of their support system and checked afterwards. Alignment alone does not repair a damaged rail or an inadequate runway beam.
Rails and joints
Wear, running surface damage or an uneven transition at a joint. We assess local repair and more extensive replacement, including removal, support preparation and position checks.
Clips and anchorage
Loose or damaged clips, bolts, bases and anchors. Replacement must suit the rail profile, loading and fixing system. Available lateral adjustment also needs checking.
Pads and rail support
Condition of resilient pads and bearing surfaces. A rubber pad is part of a designed assembly, not an arbitrary addition or a piece of interchangeable rubber. Compatibility with the rail and clips must be assessed.
Supporting structure and associated parts
Corrosion, damaged connections, beams, brackets or end stops. Protective coating and structural repair are different tasks. Where structural assessment or a modification design is required, it must precede the work.
A worn rail may be only part of the problem
When a rail moves or clips repeatedly loosen, simply ordering the same part is not enough. Geometry, support condition and loading need to be understood. Uneven wear may also relate to crane wheels and travel mechanisms. We distinguish what can be adjusted, what needs replacing and what requires further assessment. Repairing a joint locally is a different task from reconstructing an entire runway rail line.
02 / DLD SERVIS
From survey to repair
Records and site assessment
We review symptoms, records, access and crane operations.
Survey and scope
Where needed, we measure geometry and identify sections for adjustment, repair or replacement.
Shutdown planning
We agree on materials, removal, access equipment, workspace and production constraints.
Installation and checks
We carry out the agreed work and check the resulting alignment. Tests and records depend on the intervention.
What we need to know about the runway
Send the information you have. We can clarify missing details in the initial discussion.
- Location, approximate runway length and details of the cranes using it.
- Photographs of rails, joints, clips and supports; the rail profile if known.
- Symptoms, earlier surveys, drawings and inspection findings.
- Access, production restrictions and the proposed shutdown window.
Before repairing a runway
When is alignment enough, and when is replacement needed?
Geometry, rail condition and support arrangements determine the options. Adjusting position and restoring damaged parts are different tasks; we define the scope after assessment.
Does the whole runway need replacing?
Not automatically. A section can be repaired where its condition and integration with the rest allow it. Extensive wear or unsuitable support needs a broader assessment.
Can a rubber pad be added under an existing rail?
Not as a universal modification. The support design, assembly height, clips and pad properties must be checked for the particular runway.
Can the work be planned for a shutdown?
Yes. We need the scope, material availability, access conditions and details of other cranes on the same runway before agreeing on timing and method.
Show us the problem with your runway
Send photographs, the latest survey or a description of the crane behaviour. We will agree on what needs checking on site.
