Frequently Asked Questions in UAE

A tower crane is a type of machine used for heavy lifting on construction sites. It features a tall, vertical mast and a long jib (horizontal arm) for moving materials. The crane's counterweights balance the load, and its powerful hoist and trolley systems allow for precise material handling

Renting a tower crane offers cost-effective access to high-performance machinery without the long-term investment. It ensures you get modern equipment tailored to your project's specific needs, with maintenance and technical support included.

Modern fast-erecting tower cranes, like Liebherr's H series, can be set up quickly—sometimes by a single operator. Hydraulic systems and innovative design allow for fast assembly, even on uneven ground, saving valuable time on-site.

Liebherr H-series cranes offer hydraulic erection, compact transport design, and advanced safety systems. They are quick to set up, highly maneuverable, and equipped with an EDC slewing gear for smooth and precise movements.

The MK 80 mobile crane combines truck-like mobility with the functions of a tower crane. It features one-person push-button assembly, a telescopic tower, and high-speed travel capacity. This versatility makes it ideal for rapid deployment across multiple sites.

Modern tower cranes, such as the 42 K.1, feature adjustable hook heights and jib positions to accommodate various site challenges. Features like obstacle avoidance and variable jib lengths allow efficient operation even in tight spaces.

Telescopic tower cranes, like the 32 TT, offer variable tower and jib lengths. They are ideal for projects requiring flexible hook heights or working radii, especially in confined areas or urban settings.

 

Depending on the model, tower cranes can lift loads ranging from 800 kg to over 8,000 kg. Cranes like the MK 100 provide maximum lifting capacities of up to 8 tonnes with a maximum hook height of 58 meters.

Advanced safety features include electronic monitoring systems (EMS), wind-load regulation, oscillation damping, and automatic obstacle avoidance. Hydraulic systems also provide stability during operation and setup.

The EC-B series features a flat-top design with modular components for faster assembly and disassembly. It offers load curve customization, allowing operators to adjust capacity for specific tasks, enhancing productivity and cost-effectiveness.

Yes, cranes like the EC-B Flat-Top series are designed for projects with height or space restrictions. They can be configured without tower heads and are suitable for use under overhead wires or in overlapping crane zones.

Frequency-converter drives allow for stepless speed control, offering smooth, jolt-free operation. They improve precision, reduce energy consumption, and allow for micro-movement positioning—ideal for sensitive lifting tasks.

 

Crawler cranes, such as the 32 TTR, offer enhanced mobility on challenging terrain. Their tracked undercarriage provides stability and easy relocation around the site, even with the full ballast in place.

 

Many modern tower cranes are designed for easy transport. Models like the 13 H can be moved as a 2-axle trailer at speeds up to 80 km/h, making them suitable for public road use with a standard operating permit.

Liebherr cranes are built with tight-welded, solid-wall towers that resist rust and internal corrosion. High-quality components, robust hydraulic systems, and regular wear-check analysis extend the equipment's operational life.
