Renting Mobile Cranes – Important Information
Driving Permits and BF3 Support
How high, how far, how heavy? Along with information about obstructions (obstacles), these are the most important details for a lifting project. Based on these parameters, klarx calculates the most cost-effective solution from thousands of possible combinations. A small crane with additional ballast? A larger crane without extra ballast transports, but with driving permits and BF3 support? klarx keeps track of all costs and fees, finding the right solution in seconds. Regular customers order their mobile cranes with just a few clicks directly in the klarxMANAGER.
The Journey to the Job Site
klarx is responsible for the driving route on public roads from the depot to the construction site. We handle route planning, driving permits, escort vehicles, police coordination, ballast transport, accessory transport, and the necessary personnel. Since larger mobile cranes with 4m building height, 3m overwidth, and weights exceeding 100 tons often require extremely complicated routes, this is a major challenge. Up to 60 vehicles can be deployed for a single lift operation. klarx charges customers flat rates for this.
On the Construction Site
At the deployment site, you are responsible for the crane. If the crane is to be positioned on public traffic areas, the necessary permits must be obtained by the construction site. Note that lead times for permits, especially in major cities, can be up to eight weeks. Proper site security is also the responsibility of the construction site. Almost everywhere, however, there are local service providers who handle permit applications and traffic signs and barriers. We're happy to take over this service for you as well – just let us know when submitting your rental request.
The forces that occur during crane deployment are often underestimated. Mobile cranes travel with axle loads of at least 12 tons due to their high weight. This can cause damage to paved surfaces, pipes, or corridors. Since klarx cannot assume liability for such damage, you must check in advance whether the ground on private access routes can withstand this load. If in doubt, the ground must be reinforced with temporary roads, fill, or similar measures. However, the loads that occur during the actual crane operation are many times higher. The maximum corner pressures per crane foot (base plate) can be determined from the table below. The ground must be able to withstand these forces to prevent the crane from tipping over. Particularly with larger cranes, a structural analysis should always be obtained. The soil risk always remains with the rental customer – even experienced field service technicians cannot reliably determine or estimate ground load capacity without structural reports obtained on-site.

Lifting Attachments
Mobile cranes and mobile construction cranes have a crane hook for lifting loads. In addition, lifting attachments are usually needed to safely raise the load. The most commonly used are chain slings of various lengths and load capacities, spreader bars, concrete buckets, waste skips, glass lifters, and slings. Mobile cranes rarely happen to have the exact lifting attachments needed on hand. These must be provided by the construction site. If that's not possible, the appropriate lifting attachments must be specially and explicitly ordered from klarx.
Responsibility During Crane Operations
When operating mobile cranes and mobile construction cranes, this is generally a Type 2 service according to our terms and conditions for lifting and crane equipment rental. This means the crane and crane operator act on the customer's instructions and direction. They are obligated and authorized to refuse activities that violate accident prevention regulations; however, responsibility for the operation lies with the customer.

Mobile Cranes – Definition and Advantages
Mobile cranes, also called truck cranes, are mobile boom cranes that offer flexible deployment and lower setup costs compared to tower cranes. Unlike mobile construction cranes, mobile cranes can lift heavier loads, but their movement is more limited and they are not suitable for deployment in tight spaces.
