Our quality standards
Liebherr tests the materials it uses in its own modern material testing laboratory.
Liebherr continuously develops new technologies to make further improvements to quality and safety. The focal points of our research extend from materials and design principles to control and monitoring systems.
Liebherr does business only with selected suppliers and partners. That enables us to deliver uniformly high quality and safety standards.
Test loads guarantee safety
Acceptance procedure for the LR 13000 at the factory test site in Ehingen/Donau. The 3,000-tonne crane is tested during the crane acceptance procedure with test loads of up to 3,750 tonnes.
Liebherr adopts the very highest safety standards for the design of its mobile and crawler cranes. This particularly applies to the structural values. Our developers calculate every single crane's structural integrity with a safety margin of 1.5.
Every single crane has to pass a whole series of intensive, continuous tests and checks both during the entire production process and then afterwards on the factory's own test site. The test load for the crane acceptance procedure on the test site is around 25 percent higher than the standard load capacity.
After-sales service for safe crane jobs
In its capacity as the global market leader for mobile and crawler cranes, Liebherr has many years of expertise. Liebherr specialists are on hand to provide our customers with the expertise they need. For difficult jobs you can rely on our technical support. We also provide support in the form of experts on site where necessary for complex first-time jobs.
Our service includes personal induction training when you buy a new crane and a comprehensive range of training courses. This enables us to guarantee that you can complete the job safely and independently using our machines.
Used cranes
Liebherr is also specialized in used mobile and crawler cranes. We ensure the safety and durability of the cranes by our global service network. Inspected used cranes
Well designed equipment to enhance industrial safety
Crane drivers and operating personnel often have to work at great heights. Liebherr has developed an effective safety concept to provide them with the best possible safety standards. Collective safety equipment such as railings and handles on mobile and crawler cranes prevent them from falling.
In addition, we fit every new crane with a fall arrest system. The safety harnesses are attached to steel cables which run along the boom using carabiner hooks. The PPE has undergone a whole series of tests and has received multiple certificates from state safety authorities.
Collective and personal fall arrest systems
During everyday work you often do not have a free hand to hold on to safety equipment. Railings on the vehicle prevent falling.
The anti-slip coating on the boom prevents accidents. A fall arrest device provides additional safety for personnel.
Liebherr quality in detail. The crane's equipment includes a ladder with a height-adjustable attachment lug.
A special holder on the crane ensures that the ladder does not slip.
The PPE is attached to steel cables which run along the lattice mast boom in double strands.
Safe working with derrick ballast
Liebherr also attaches great value to safe working practices with additional equipment. For example, our ballast trailers feature a wide range of safety equipment.

Underestimated risk: Wind and crane operations
Liebherr has 40 years of experience in the production of mobile cranes. We are committed to making crane operations safe and pass on our expertise to ensure this. One of our focal points in this respect is the clarification of risks and dangers caused by the effects of wind. Liebherr provides the requisite practical expertise for crane drivers and contractors in the form of professional training documents and courses.
Wind - identifying the risks
Wind can exert additional or reduced forces on a crane and can change character in a matter of seconds. It acts on both the load and the crane. Wind from the side exerts a massive additional load on the lateral stability of the crane. The wind load can often not be detected by the crane control.
In addition the form and weight of the load can also have a major impact for the effects of wind. For example, loads with large surface areas exposed to the wind, such as rotor blades, can exceed the parameters from standard load capacity tables.
Liebherr provides information about the effects of wind on crane operations and provides simple, readily understandable training on how to calculate the maximum permitted wind speeds in a given situation. This is the only way to make these crane jobs safe.
But one rule applies in every case: "Double the wind speed means four times the wind loading on the boom and load."

The video explains how high wind speeds really affect crane operations and what action must be taken.
Rescue sheet for Liebherr mobile cranes
The rescue sheet shows the structure of the crane and provides information about any hazardous substances on it.
Liebherr is supplying its mobile cranes with a rescue sheet since several years. This shows the structure of the crane and any hazardous substances on it. It is a tool to provide valuable help to fire service and recovery personnel for rescuing personnel and recovering the mobile crane after an accident.
Practical content
The Liebherr rescue seat is located behind the driver's seat.
The rescue sheet is an information sheet which provides details of the vehicle's structure and the best places to cut the bodywork open. It provides details of the relevant media on the crane, for example fuels and oil, their hazard class, volumes and precise location. In addition the structure of the driver's cab and crane cab, including the seats and their adjustment functions are shown.
The first crane models were supplied with the rescue sheet in 2011. Liebherr now delivers all LTM and LTC cranes which comply with emissions stage 3b or over with a rescue sheet.
Rescue sheets are adapted to the specific machine. That means they cannot be supplied on this website for downloading. To ensure that the correct rescue card is used, Liebherr supplies it in the crane behind the driver's seat.
Collaboration with the fire service
In addition to advice and the exchange of information with the local fire service, it also conducted intensive practical tests on driver's cabs and crane cabins.
A project team at Liebherr-Werk Ehingen GmbH developed rescue sheets for Liebherr mobile cranes to make it easier for recovery personnel to rescue passengers quickly and safely after traffic accidents or accidents on sites. In developing the concept Liebherr worked closely with the local fire service from Ehingen.
Competence for fire service cranes
Liebherr has been manufacturing standard cranes with additional fire service equipment for over 40 years for professional fire services. More than 100 Liebherr fire service cranes with load capacities of between 25 and 70 tonnes are in use all over Europe. Fire service cranes
