Renting Mobile Cranes – Important Information
Driving Permit and BF3 Escort
How high, how far, how heavy? Along with information about obstructions (obstacles), these are the most important pieces of information 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 transport, but with driving permit and BF3 escort? klarx keeps track of all costs and fees and finds the right solution in seconds. Regular customers order their mobile cranes with just a few clicks directly in the klarxMANAGER.
The Route to the Construction Site
klarx is responsible for the driving route on public roads from the depot to the construction site, taking care of route planning, driving permits, escort vehicles, police coordination, ballast transport, accessory transport, and appropriate personnel. Since larger mobile cranes with 4m building height, 3m overhang width, and dead weights of over one hundred tons often require very complicated driving routes, this is a major challenge. Up to 60 vehicles can be deployed for a single lift operation. klarx charges customers here with flat-rate prices.
On the Construction Site
At the job site, the customer is responsible for the crane. If the crane is to be positioned on public traffic areas, appropriate permits must be obtained by the construction site. It should be noted that the lead time for this can be up to eight weeks, especially in major cities. The proper securing of the job site is also the responsibility of the construction site. However, local service providers are available almost everywhere who obtain permits and take care of traffic signs and barriers. We're happy to provide this service for you as well – simply let us know when submitting your rental request.
The forces occurring during a crane operation are often underestimated. Mobile cranes travel with axle loads of at least 12 tons due to their high dead weight. This can cause damage to paved surfaces, pipes, or hallways. Since klarx cannot assume liability for such damage, it must be checked in advance whether the ground at private access roads can withstand this load. In case of doubt, the ground must be reinforced with construction roads, embankments, or similar measures. However, the loads that occur during the crane operation itself are many times higher. The maximum corner pressures per support foot (pad) of the mobile crane can be determined from the table below. The ground must be able to withstand this load to prevent the crane from tipping over. Especially for larger cranes, a structural engineer's assessment should always be obtained. The ground risk generally lies with the renting customer – even experienced field service employees are not able to reliably determine or estimate the ground's load capacity without structural assessments obtained by the construction site.

Lifting Accessories
Mobile cranes and mobile construction cranes have a crane hook for lifting loads. In addition, lifting accessories are usually needed to safely raise the load. The most commonly used are chain hoists of varying length and load capacity, spreader beams, concrete buckets, debris chutes, glass lifters, and lifting slings. Mobile cranes rarely have exactly the right lifting accessories on hand. These must be provided by the construction site. If this is not possible, appropriate lifting accessories must be ordered separately and explicitly from klarx.
Responsibility During Crane Operation
When using mobile cranes and mobile construction cranes, this is typically a service of Type 2 according to our Terms and Conditions for the rental of lifting and crane equipment. This means that the crane and crane operator act at the customer's instruction and discretion. They are instructed and authorized to refuse activities that are not in compliance with 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 are flexible in application and have lower setup costs, which is an advantage compared to tower cranes. Mobile cranes can lift heavier loads compared to mobile construction cranes, but their movement is restricted and they are not suitable for use in narrow spaces.
