The Liebherr family is gaining a new major customer in Jandt Kranvermietung GmbH: With the mobile crane LTM 1400-6.1, the family-run company is entering the 400-ton class for the first time, marking a strategic milestone in the development of its crane fleet. The new 6-axle mobile crane is the largest equipment in Jandt's fleet to date and significantly expands its service capabilities. Previously, the fleet's top performers were two LTM 1250-5.1 units and two mobile tower cranes MK 140-5.1 – for growing load requirements in the market, this capacity had reached its limits.

"With this move into a larger crane class, we are making a clear statement about our business development and of course responding to market demands," explains Jens Lübeck, one of two managing directors of Jandt Kranvermietung GmbH. "As loads continue to grow, we reached the limits of our current fleet in some areas and could only fulfill project requirements in cooperation with our partner companies."

Why the LTM 1400-6.1 is the right choice for Jandt

The LTM 1400-6.1 is the first 6-axle crane in Jandt's fleet. The investment decision was based on three key criteria that are crucial for practical operation:

  • Compact dimensions: Despite high load capacity, the crane remains comparatively compact in its load class – an advantage on confined construction sites and infrastructure projects.
  • High lifting capacity: With 400 tons rated capacity, the LTM 1400-6.1 covers projects for which Jandt previously had to rent external cranes.
  • Self-assembly Y-bracing: Liebherr has designed the Y-telescopic boom bracing system so that safety during assembly increases significantly. Fewer assembly steps mean less work at height – a considerable advantage for operating personnel.

"We really like the quick-connect system, which allows us to significantly reduce setup times," reports Sven Diercks, who is responsible for the technical side of Jandt's management. "With the LTM 1400-6.1, we can implement high-load operations more flexibly and with shorter lead times."

New areas of application: Energy transition and power line construction in focus

With the new 6-axle crane, Jandt opens up areas of application that were previously beyond its capacity. "Since we already operate in many areas and have had to rent cranes in this size class in the past, we are particularly pleased about the new applications," says Lübeck. The company specifically names four priorities:

  • Industry: Assembly of heavy plant components, turbines, steel structures
  • Infrastructure projects: Bridge construction, civil engineering works, large-scale construction sites
  • Energy transition: Wind turbines, transformer substations, solar projects
  • Power line construction: Assembly of high-voltage towers, where Jandt has been active for several years

In particular, the expansion of renewable energy is driving the demand for large cranes. Wind turbines are becoming larger, heavier, and more demanding in assembly – a development that continues to increase the need for powerful mobile cranes. Six-axle cranes are also increasingly sought after for grid expansion projects related to the energy transition.

What makes the 6-axle crane technically special?

The LTM 1400-6.1 offers several technical features that make practical operation easier. Liebherr's automatic coupling system LIKUFIX significantly reduces assembly times as hydraulic and electrical connections are coupled automatically. Secure access and platforms reduce accident risk during setup. The reduced number of assembly steps at height significantly increases personnel safety – an aspect Jandt highlights as a decisive purchase argument.

The compact dimensions relative to the load class are another advantage: while classic 400-ton cranes often require 7 or 8 axles, the LTM 1400-6.1 makes do with six axles. This facilitates transport and enables deployment on construction sites with limited space.

Long-term partnership with Liebherr as the foundation

The decision for the LTM 1400-6.1 was no coincidence. Jandt has relied on Liebherr technology for years. "Liebherr's innovative power as well as our long-standing partnership and high level of service have once again convinced us to purchase a Liebherr product," explains Lübeck. "The extremely economical operation of Liebherr equipment was also a decisive purchasing argument."

This continuity is also evident in the overall fleet: In addition to mobile cranes, Jandt operates four mobile tower cranes – two MK 140-5.1 and two MK 88-4.1 – also from Liebherr. The company's expertise lies particularly in supporting industrial and hall construction. With a total of 18 mobile cranes and four load cranes, Jandt is among the medium-sized crane rental companies with a broad range of applications.

Family tradition since 1950 – now in third generation

Jandt Kranvermietung GmbH looks back on a 75-year history. Founded in 1950 with haulage and excavation work, the company was restructured in 1998 and has been in the second generation since then. The third generation is already in the wings. Over the decades, Jandt evolved from an excavation business to a specialist in all types of crane work – with a clear focus on mobile cranes and mobile tower cranes.

The investment in the LTM 1400-6.1 is thus not just a technical step, but also a strategic signal: Jandt is positioning itself for future project requirements and is responding proactively to market changes. With the new large crane, projects can be executed that were previously only feasible in cooperation with partner companies. This means greater independence, shorter lead times, and more direct customer communication.

What the move means for crane rental companies

Entry into the 400-ton class is a significant investment for a medium-sized crane rental company. In addition to acquisition costs, requirements for logistics, personnel, and maintenance also increase. At the same time, a new market segment opens up: large projects with heavy loads that promise stable order books. Particularly in the energy transition and infrastructure sectors, demand for powerful mobile cranes has risen in recent years – a trend expected to continue.

For construction companies and project managers, the expansion of Jandt's fleet means more options and shorter availability times. Those who previously had to rely on multiple suppliers for large projects now find a broader palette with a regional partner. This shortens coordination processes and simplifies construction site logistics – a non-negligible advantage for complex infrastructure projects.

Jandt's investment also shows that the market for large cranes is in motion. While smaller mobile cranes are increasingly being modernized through electrification and telematics, crane rental companies in the heavy-duty class continue to rely on diesel-hydraulic drives with high load capacity and proven technology. The focus here is on reliability, quick setup times, and high safety – aspects that the LTM 1400-6.1 optimally combines according to manufacturer specifications.
