ALE AL.SK350

Customized Cranes

The ALE AL.SK350 is a 5,000-ton super heavy lift crane, designed for mega infrastructure, offshore, and industrial projects requiring extreme lifting capacities. It features a 126-meter (413-foot) main boom, extendable to 344 meters (1,128 feet) with a jib, making it the largest land-based crane in the world at the time of its introduction. The AL.SK350 utilizes a 4,000-ton ring-based ballast system and a high-capacity winch system, enabling it to lift ultra-heavy loads with precision and efficiency. Developed by ALE (now part of Mammoet), this crane is used in oil and gas, power plant construction, and modular lifting operations, where conventional cranes cannot handle the scale and weight of the lifts.

Product Description

The ALE AL.SK350 is a record-breaking super heavy lift crane, designed to handle the heaviest and most complex lifting operations worldwide. As an evolution of the AL.SK190 and AL.SK300, the AL.SK350 was introduced as the world’s largest land-based crane, capable of lifting 5,000 tons in a single lift. This crane is particularly suited for large-scale industrial applications, including oil refinery construction, offshore platform assembly, and power plant module installation, where traditional crawler or ring cranes cannot meet the required lifting capacity.

One of the key features of the AL.SK350 is its 126-meter (413-foot) main boom, which can be extended to 344 meters (1,128 feet) using a jib system, making it capable of lifting extremely heavy loads to significant heights. The crane operates on a hydraulically powered 4,000-ton ring-based ballast system, which distributes the load efficiently and enhances stability. It also incorporates a high-capacity strand jack winch system, providing precise load control and smooth lifting cycles.

The AL.SK350 is designed for high efficiency, requiring only a fraction of the space that traditional cranes need, allowing it to work in confined environments such as congested refinery or port facilities. The crane’s computerized load management system ensures safe and optimized lifting operations, while its remote-controlled operation allows for enhanced precision.

A major advantage of the AL.SK350 is its ability to perform lifts without requiring extensive ground reinforcement, reducing setup time and project costs. The ring-based structure and counterweight system allow for 360-degree continuous rotation, enabling efficient load handling in limited space.

Since its introduction, the AL.SK350 has been deployed in multiple high-profile projects, including offshore wind farm installations, modular refinery construction, and nuclear plant development. The crane is part of ALE’s (now Mammoet’s) fleet of ultra-heavy lifting solutions, representing the cutting edge of lifting technology.

With its unmatched lifting capacity, advanced ballast system, and innovative design, the ALE AL.SK350 is a game-changer in the world of super heavy lifting, providing unprecedented capabilities for handling the largest industrial components and infrastructure modules in the world.
