Who can inspect and evaluate used harbour cranes?

MEVAS has been a recognised expert for used cranes of various types for many years. Damage reports are prepared for mobile cranes or lattice boom cranes. The core area is the inspection and determination of the technical condition of cranes. In addition to this technical inspection, there is also very often the requirement to determine the value of used cranes. Harbor Crane inspection is part of our service. These appraisals are often necessary for crane buyers in order to enable financing by the bank or leasing company. For this reason, we also regularly prepare expertises on the current value of cranes.

If you need an inspection or valuation of harbour cranes contact us today. As we often deal with large machines, we know what the depreciation of such machines looks like. We know about transport, dismantling and assembly of larger equipment costs. We therefore also feel able to determine the value of harbour cranes.

Fair values for internal sales of harbour cranes

In the world’s harbours, the operators of mobile equipment and handling machines change regularly. However, it is often the case that a harbour crane spends a large part of its life in the same port. This has to do with the fact that dismantling, shipping and assembly at a new location incur dramatically high costs. These costs often exceed the current value of the machine. Harbour cranes can reach very high hourly levels. For this reason, it is often the case that the new operator tries to continue using the existing equipment and purchase or rent it. To avoid disputes, or at the request of the bank, it is often necessary to have an independent valuation of harbour cranes carried out. This should be carried out by persons who have no interest in buying or selling such equipment. We at MEVAS have the expertise and personnel to undertake such work. We are not afraid of big iron and have already inspected and assessed various harbour cranes.

Where does MEVAS inspect harbor cranes?

Harbour cranes can be found in every port in the world. It’s the same with our inspection service: MEVAS inspects machines for customers all over the world and we also travel everywhere for inspections. We have local inspectors in 22 countries. We also have excellent networks to find local technicians in other countries. For important jobs, the team from Germany personally travels to the harbour to inspect and assess cranes and large handling machines. Please contact us with an enquiry and we will answer you in a short time whether we feel able to inspect cranes at your location. If we have no idea about the specific technology in your operation, we will tell you and not accept the order.

What is a harbour crane and what is it mainly used for?

A harbour crane, also known as a port crane or ship-to-shore (STS) crane, is a specialized, large crane used in ports and harbors for the loading and unloading of cargo ships. These cranes are essential for moving containers and other heavy cargo efficiently between ships and the dock, supporting global trade and transportation.

Key Features of Harbour Cranes

1. Size and Reach: Harbour cranes are very tall, often towering over ships, with a long boom that can extend over the width of large cargo vessels.
2. Lifting Capacity: They are designed to lift heavy loads, often capable of handling containers weighing 20–40 tons, with some able to lift up to 100 tons or more.
3. Mobility: Some harbour cranes are fixed in place, while others are mounted on rails or tires to move along the port’s length.

Types of Harbour Cranes

• Ship-to-Shore (STS) Cranes: Used for loading and unloading containers from container ships.
• Mobile Harbour Cranes: Versatile cranes that can move around the port and handle various types of cargo.
• Floating Cranes: Mounted on barges for use in deeper water where fixed cranes cannot reach.

Main Uses of Harbour Cranes

1. Container Handling: Most modern harbour cranes are designed primarily for lifting and placing containers.
2. Bulk Cargo Handling: For unloading bulk goods like coal, grain, or minerals.
3. Heavy Cargo Lifting: Used to handle oversized or non-containerized cargo such as vehicles, heavy equipment, or parts for construction projects.

A better service for used crane inspections

Are you looking for an inspector for a used crane? Did you come across or did you hear from SGS or TÜV? If you are looking for statutory or safety inspections for cranes SGS is a good solution. Well trained staff and available in many countries.

Does SGS understand used cranes?

There is a difference between inspection of a used crane for a buyer and a safety or statutory inspection. An inspector who is trained for Loler or OSHA inspections does not necessarily understand what a purchaser of a used crane wants. This is the situation when MEVAS comes on stage.

Crane inspections by our experts

MEVAS inspectors understand, how to prepare a reasonable inspection report for buyers of used cranes. A detailed report focuses on machine details such as leaks, maintenance status, wear in ropes, wear on tires and other details which are influencing the remaining value of a crane. Our technicians know how to take reasonable pictures and videos. They crawl under the crane to search for cracks and leaks. Rust on chassis is estimated as well as condition of tool boxes, swing bearing and telescopic cylinder condition. Our engineers use a specific checklist for each type of crane. We have inspected mobile cranes up to 500 to lifting capacity and large crawler cranes for windmills.

Where to find used mobile and ATT cranes

How much tilting play is allowed in the slewing ring of a mobile or a crawler crane?

Ask three specialists and you will get three different answers. If you ask Liebherr, i.e. the people who would like to sell you a repair or a new slewing ring, you will get the statement that the tolerance limit would be reached at 0.9 mm tilting play. If you ask a mobile crane user in Eastern Europe or Africa, they will say anything under 5mm is fine.

What does a crane inspector say about swing bearing play?

As inspectors of used cranes, what is our opinion on this? Since the tilting play in the slewing ring is sometimes 0.3 to 0.6 mm even on new cranes, we do not think it is necessary to criticize a slewing ring if it has less than 1.2 mm tilting play. To know exactly, you should also measure the slewing ring play over at least three or four sides. Experienced inspectors know exactly how the procedure must be carried out. It is particularly important that the crane is ballasted. When we inspect a used mobile crane, we typically only measure across one side. Only when there are doubts about the condition is it measured over several pages.

Why is it important to measure swing bearing play from time to time on a mobile crane?

Measuring swing bearing play on a mobile crane is crucial for several reasons, and it plays a significant role in ensuring the safe and efficient operation of the crane. Here are some key reasons why it’s important to regularly measure swing bearing play:

1. Safety:
   • Excessive swing bearing play can compromise the stability and structural integrity of the crane, leading to potential accidents or tip-overs. Regular measurements help identify issues before they become critical, ensuring the safety of both operators and bystanders.
2. Equipment Longevity:
   • Monitoring swing bearing play allows early detection of wear and tear. Addressing any play or movement issues promptly helps prevent further damage to the swing bearing and other related components, thus extending the overall lifespan of the crane.
3. Operational Performance:
   • Properly functioning swing bearings are essential for smooth crane operation. Excessive play can lead to imprecise control and reduced accuracy during lifting and positioning tasks. Regular measurements help maintain optimal operational performance.
   • Imagine a crane has the boom extended to 80 or more meters and there is 5mm play on swing bearing. On getting load the tip would reduce height and angle of boom significantly.
4. Preventive Maintenance:
   • Regularly checking swing bearing play is a part of preventive maintenance practices. Identifying and addressing potential problems early can prevent more extensive and costly repairs in the future, minimizing downtime and maximizing crane availability.
5. Regulatory Compliance:
   • Many regulatory bodies and safety standards require periodic inspections and maintenance of crane components, including swing bearings. Regular measurements help ensure compliance with these regulations and standards, reducing the risk of legal and financial consequences.
6. Cost Savings:
   • Proactive maintenance based on regular measurements can be more cost-effective than reactive repairs. Early identification and correction of swing bearing issues help avoid major breakdowns and the associated costs of emergency repairs and crane downtime.
7. Reliability:
   • A crane with a well-maintained swing bearing is more reliable and less likely to experience unexpected failures. This reliability is crucial in construction and industrial settings where cranes play a vital role in various operations.

In summary, measuring swing bearing play on a mobile crane is essential for maintaining safety, extending equipment life, ensuring optimal performance, complying with regulations, and ultimately minimizing costs associated with repairs and downtime. Regular inspections and maintenance contribute to the overall reliability and efficiency of the crane in its operational environment.

How much does it cost to replace a worn slewing bearing?

Depending on size and lifting capacity of a crane or an excavator the swing bearing itself can easily cost above 8.000 Euro. Then you need all the pins to fix it on superstructure and chassis. That’s another 1.500 Euro at least. But with this cost the slew ring hasn’t been exchanged yet. Cranes are required to lift the superstructure. You need big tools to open and fit the pins with appropriate torque. All in all the replacing cost for a sllew ring will be in most cases far above 10.000 Euro.

For the reason of the big cost it is strongly recommended to measure the play if you are buying a crane or a larger excavator. Hire an expert to inspect a used crane and check out those details.
