Demag service

Inspection and maintenance


Smooth and reliable. To ensure your equipment delivers performance.

With our tailored solutions for inspection and maintenance, we help you to ensure that your equipment offers the performance you need: regular and reliable performance for optimum equipment availability and a high level of safety for owners and operators. We only work with qualified specialists who have a wealth of experience – and who are not only familiar with our own products. We offer inspection and maintenance work for cranes, hoists, load handling attachments or other related equipment from Demag, or any other brand.

Maintenance and inspection is carried out according to our specifications, which are based on relevant local regulations.

Prevent malfunctions

Prevent malfunctions

Normal use of any equipment will result in wear of components, which may cause malfunctions. We can carry out inspections of your equipment to prevent any potential malfunctions as early as possible – to enable damage or wear to be identified and eliminated in good time.

Scheduled maintenance

In addition to inspections, equipment must be maintained regularly and appropriately by trained personnel in line with the specified deadlines and checked according to their maintenance schedule. We can also take care of that for you. Wearing parts are replaced in good time, any dirt accumulation is removed, oil and grease can be refilled – to ensure that everything runs smoothly and as a matter of course, we only use genuine spare parts.

Short response times

Thanks to the wide coverage provided by our network of skilled service teams, we can quickly reach your site – for regular inspections and also in an emergency.

Deadline management

In the scope of our service agreements, we can help you to meet prescribed deadlines. We will contact you to confirm an appointment for the next inspection deadline.

Revolving warranty

For more demanding requirements: extended liability for defects on Universal Cranes. We can offer you continuous, reliable operation of your equipment and, at the same time, predictable costs with our revolving warranty – which goes beyond our normal terms and conditions. The agreement ends when the theoretical duration of service elapses, however, no later than after ten years.

Reliable liability arrangement

Reliable liability arrangement

As part of our revolving warranty, liability for defects for a crane is renewed under precisely defined conditions – until the next safety check is due after every service inspection. This protects you from any new costs that might be incurred as a result of unforeseen defects. The intervals between the inspections are specified together with you depending on the crane operating conditions and reviewed after the first year of operation.

Further benefits

  • Reliable planning based on known costs
  • Annual reminder of legally required inspection
  • Service provided by the manufacturer
  • Reduced hourly rates for repairs


  • Owner must use products as intended
  • Professional maintenance by Demag service technicians as part of a service agreement
  • Immediate, proper elimination by the owner of any defects on parts reported during the service that are not covered by the revolving guarantee

More information

Scope of services

  • Period of 10 years
  • Extension of liability for defects after every service inspection (until the next service inspection is due)
  • Repair at no cost or replacement of defective parts

10+2 extension

In the tenth year of the service agreement we assess the general condition of your equipment and decide, based on the results of the assessment, whether the requirements for an extension of the revolving warranty are fulfilled.

After a positive assessment, we offer you an extension to our agreement for two years with a price increase of 10%.

Service agreement

Service agreements offer optimum care throughout the entire life cycle of your equipment – for optimum safety, reliability and availability. Cranes, hoists and load handling attachments of all types perform tasks in a wide variety of industries every day. If equipment breaks down, the flow of material is interrupted, handling cycles cannot be maintained and production processes are disrupted or brought to a standstill. That costs money. For this reason, we ensure that failures are minimised.

Surveys on crane runways and crane geometry

Avoid production stoppages and cost-intensive repair work, prevent breakdowns and detect damage to building structures at an early stage of development. Regular surveys of your crane runways carried out by our specialists help you to ensure maximum reliability in production. Benefit from the reliability and accuracy of our professional surveys, which are conducted by our experienced survey engineers.

Safety all along the line

The travel characteristics and, therefore, the optimum availability of your equipment is impaired when specified tolerances are exceeded – which can result in premature wear of the travel wheels, sudden changes in travel speeds and unexpected load sway. Optimum travel properties can only be ensured by perfectly aligned crane runway and crane geometry, which give you the certainty of safety all along the line.

Fast, accurate and reliable

Demag Laser measuring system LMS

The survey methods that we employ are fast, safe and reliable and can be used for any product – in particular, our internationally patented LMS laser measuring system provides highly accurate survey results. On the basis of a visual inspection, a review of the equipment and the survey results, we assess any possible repair requirements – and recommend cost-effective corrections to eliminate any defects that are found.

Crane runway surveys

Crane runway surveys

We perform automatic, three-dimensional surveys of crane runways with our internationally patented LMS laser measuring system – which takes each measurement multiple times, resulting in accuracy better than 0.5mm. Intelligent sensors help to achieve this high level of reliability for all types of rails and also worn profiles. When the measuring process has been completed, the results are shown in real-time visualisation.

Further benefits

    • Precise measurement and corrections for high-quality requirements (e.g. for automatic or multi-shift operation)
    • Minimised wear
    • Reduced maintenance costs
    • Increased availability of your equipment

    Geometry surveys for crane & crab

    Geometry surveys for crane & crab

    The survey is conducted using precision theodolite and tachymeter as well as precision reflectors and nonius. The crane will be raised using hydraulic lifting equipment to achieve measurements without any tension in the superstructure. Consequently all wheels are measured directly to each other through rotation in several positions in the wheel axle or exact to the wheel surface. The measurement is extremely accurate and complies with all relevant standards and guidelines.

    Further benefits

    • Guarantee of virtually wear-free operation (rails, wheels)
    • Crane operating characteristics are optimised in terms of travel properties, precise positioning, smooth starting and braking, unnecessary vibrations are eliminated
    • Entire process sequence is optimised

    Special surveys

    Thanks to our wealth of experience, we are able to conduct a whole range of special surveys. Our engineers will be pleased to advise you on specific requirements.

    Possible scope of services

    • Alignment of travel wheel guide rollers
    • Survey and assessment of ground and guide rails (also for storage and retrieval machines)
    • Surveys of suspension crane equipment
    • Assessment of clearance dimensions before new cranes are ordered and installed
    • Measuring the flatness of magnet poles
    • Dynamic deflection of crane girders, crane runway supports and beams when a load is applied
    • Check of vertical differences between building columns
    • Measuring the flatness of slewing rings

    IDAPSY Inspection, Diagnosis and Application System

    IDAPSY offers you comprehensive opportunities for equipment management, diagnosis and optimisation in one system. IDAPSY enables you to read out and analyse error messages and operating data such as the remaining service life (load spectrum), contactor switching operations or error statistics. At the same time, IDAPSY manages data using software and hardware. We have developed this new integrated service tool specifically for our DR rope hoist and DC chain hoist.

    Lasting efficiency

    Any data recorded using IDAPSY offers you outstanding opportunities for analysis and optimisation, both on site and at a later date.

    The capture and evaluation of operating data, for example, make it possible to schedule a service inspection in good time – to ensure that your equipment is in optimum condition at all times. Error messages and statistics can also be called up in the same way when maintenance or repair work is carried out.

    All of the data saved by the software can be transmitted via the Internet to a central server, where they can be called up again at a later date. As a result , IDAPSY enables service work to be scheduled in advance and helps to avoid any downtime – providing the basis for many years of reliable and efficient utilisation.

    Equipment versatility

    Using IDAPSY software, the parameter data sets for DR rope hoists can be modified on site – for example, if limit switches need to be added at a later date, the load detector is optimised or, if the system is converted to inverter-fed operation or synchronised control.

    Service intelligence for peace of mind

    IDAPSY also guarantees access to product history data (default settings, previous service work) at any time. Besides the ability to save all data on a PC (notebook), data and parameter data sets can also be saved on a central server by means of export and import functions, ensuring that your equipment data is continuously backed up and saved.
