There is a question that comes up in almost every plant maintenance meeting, and it rarely gets a satisfying answer: what exactly is included when you call in a crane service team?
Most facility managers have experienced at least one situation where a service visit was completed, a report was signed off, and within weeks the crane was back to causing problems. The technician came, ticked some boxes, and left. Nothing meaningful changed.
If your facility depends on DEMAG crane service to keep overhead lifting equipment operational and safe, you deserve a clear, detailed answer to that question. Not a vague list of service categories but a genuine breakdown of what professional crane servicing involves, why each element matters, and what you should be holding your service provider accountable for.
That is exactly what this guide delivers.
There is a meaningful difference between a basic maintenance visit and a professional, comprehensive crane service program. Basic servicing typically involves a visual check, some lubrication, and a quick test run. It is fast, inexpensive, and largely ineffective at preventing the failures that cause real downtime.
Professional DEMAG crane service is systematic. It follows a structured methodology aligned with applicable standards including ISO 9927 for crane inspection and IS 3177 for electric overhead travelling cranes. It addresses the mechanical, electrical, structural, and safety dimensions of the crane as an integrated system rather than a collection of isolated components.
The difference shows up not during the service visit but in the months afterward, in the form of fewer breakdowns, more consistent performance, and a maintenance record that satisfies regulatory and insurance requirements.
Mechanical servicing forms the operational foundation of any crane maintenance program. On DEMAG cranes, this encompasses the hoist unit, travel mechanisms, and all associated power transmission components.
Hoist Mechanism
The hoist is the highest-stress component on any overhead crane. A professional service visit addresses every element within the hoist assembly:
Travel Mechanisms
Long travel and cross travel units receive the same systematic attention:
General Lubrication
A professional service includes a full lubrication round covering every greased point on the crane. This is not a random application of grease but a structured lubrication with the correct lubricant type at each point, documented quantities, and verification that each lubrication point is free of contamination before fresh lubricant is applied. Lubricant mixing from incorrect greasing is a common and avoidable cause of bearing failure.
Brakes on DEMAG cranes are safety devices first and motion control components second. A professional service treats them accordingly.
Hoist Brake
DEMAG hoist brakes are spring-applied, electrically released disc brake units. Professional service covers:
The hoist brake holding test is a critical safety verification step. Any brake that cannot hold rated load must be taken out of service immediately pending repair.
Travel Brakes
Cross travel and long travel brakes receive inspection of lining condition, spring tension, and brake gap. Travel brake stopping distance is tested and compared against the design specification for the crane speed and weight class.
Electrical faults are among the leading causes of crane breakdowns and, when left unaddressed, can escalate into fire risk or control system failures that affect safety. Professional DEMAG crane service covers the full electrical system.
Control Panel and Power Circuit
Motor Inspection
Variable Frequency Drives
On modern DEMAG cranes with VFD control:
Limit Switches
Every limit switch on the crane is individually tested during a professional service:
Pendant and Remote Controls
Conductor Bar and Collector System
The structural condition of a crane is assessed through systematic visual inspection supplemented by measurement and, where indicated, non-destructive testing.
Main Girder and End Carriages
Runway Structure
Fasteners and Connections
Where crack indications are found during visual inspection, professional service includes magnetic particle inspection or dye penetrant testing at the affected location to characterize the indication and determine the corrective action required.
Following any major repair, component replacement, or at defined periodic intervals, a professional DEMAG crane service includes formal load testing.
Static Load Test
A static load test applies 125 percent of the crane's safe working load in a controlled lift to verify structural integrity under overload conditions. The crane is held at each test position for a minimum of ten minutes while the structure is observed for deformation or distress.
Dynamic Load Test
A dynamic load test applies 110 percent of the safe working load and exercises all crane motions under load to verify brake performance, structural response to dynamic forces, and control system function.
Safety Device Function Test
All safety devices are tested under loaded conditions including the overload protection device, all limit switches, and the emergency stop system. A safety device that only works in theory and has never been tested under actual operating conditions provides no real protection.
A professional crane service is only complete when it is properly documented. The service report is not a formality. It is a legal and operational record that should include:
This documentation forms part of your crane's service history and is required for regulatory compliance, insurance purposes, and informed future maintenance planning.
There are specific failure modes that almost never get caught during a cursory service visit but are consistently identified during a systematic professional inspection. These include:
These are the findings that prevent the kind of failure that shuts down a plant and puts workers at risk. They are only found by service engineers who know what to look for and take the time to look properly.
A one-off service visit is better than nothing but it cannot deliver the same reliability outcomes as a structured preventive maintenance contract. A properly designed contract for DEMAG crane service specifies:
For facilities running DEMAG cranes on heavy-duty cycles, a preventive maintenance contract is not an overhead cost. It is a production continuity investment.

Q1: How is a professional DEMAG crane service different from a routine maintenance check? A routine maintenance check typically covers lubrication and a visual inspection. A professional service is a comprehensive, documented assessment of every mechanical, electrical, structural, and safety element of the crane, conducted by trained engineers using calibrated tools and following a structured methodology aligned with applicable standards.
Q2: How long does a professional DEMAG crane service take? Duration depends on crane size, configuration, and condition. A standard single girder EOT crane in good condition may take four to six hours for a thorough service. A large double girder crane with complex electrical systems and an extended runway may require one to two full days. Any service provider who completes a comprehensive inspection significantly faster than this should be asked to explain what was covered.
Q3: What qualifications should DEMAG crane service engineers have? Service engineers should hold relevant electrical and mechanical trade qualifications, have documented product-specific training on DEMAG crane systems, and be familiar with applicable standards including ISO 9927 and IS 3177. For load testing, the responsible engineer should be a competent person as defined under applicable occupational safety regulations.
Q4: Can a professional service be conducted while the crane is in production use? Some elements of inspection can be conducted during operational pauses but a full professional service requires the crane to be isolated and locked out. Attempting to conduct a meaningful mechanical and electrical inspection on a crane that is still in intermittent use is unsafe and results in incomplete findings.
Q5: What should I do if the service report identifies defects I cannot address immediately? Any defect involving a safety-critical component such as the hoist brake, wire rope, overload device, or structural crack must be addressed before the crane returns to service. Non-safety-critical defects can be scheduled for correction within a defined timeframe. Your service provider should clearly differentiate between immediate action items and deferred maintenance recommendations in the report.
A professional DEMAG crane service is not a single activity. It is a structured, multi-disciplinary program that systematically addresses every dimension of crane condition and safety. From brake holding tests and wire rope assessment to VFD fault log review and structural weld inspection, every element described in this guide serves a specific purpose in keeping your crane reliable, compliant, and safe.
The question to ask your current or prospective service provider is not just how much the service costs. It is what exactly they cover, how they document their findings, and what happens when they find something that needs attention.
When you are ready to work with a service partner who takes that question seriously, Times Krane is ready to have that conversation.

India's industrial crane market has expanded rapidly over the past decade. Steel plants, automobile facilities, port infrastructure, and large-scale EPC projects are all driving demand for overhead material handling equipment. With this growth has come a proliferation of crane suppliers, ranging from highly capable engineering-driven manufacturers to assembly-focused vendors offering near-identical catalogue specifications at aggressive terms.

Walk into any high-output manufacturing facility, steel plant, or automobile assembly shop, and one piece of equipment quietly holds the entire operation together: the overhead crane. When it performs well, nobody notices. When it fails, production halts, timelines collapse, and the safety of the entire floor is immediately at risk.

In a high-throughput automotive plant, a crane breakdown during a critical production shift once cost a major OEM over 18 hours of unplanned downtime. The financial loss ran into several crores. The root cause traced back to a poorly specified EOT crane purchased on the basis of lowest bid, from a manufacturer with no documented load-testing protocol. Stories like this play out across Indian and global manufacturing floors every year, and they illuminate a truth that procurement teams are increasingly internalizing: selecting industrial EOT cranes manufacturers is not simply a capital expenditure decision. It is a long-cycle operational investment that shapes plant productivity, workforce safety, and asset uptime for 20 years or more.
