Jaso continues to push the boundaries of innovation with the unveiling of two models: the J638PA, launched last year, and the newly introduced J165.8 flat top tower crane. Both cranes represent a significant leap forward in crane technology, offering unparalleled performance, efficiency, and sustainability for construction projects worldwide.
The J638PA: A New Standard in Luffing Tower Cranes
Introduced last year, the J638PA Luffing Tower Crane offers impressive reach, lifting capacity, and operational flexibility. Developed in collaboration with industry partners, the J638PA is built to meet performance standards in regions such as the US, Canada, Europe, the Middle East, Asia, and Oceania.
The J638PA offers a maximum reach of 65 meters (213 feet), providing construction teams with greater flexibility in accessing hard-to-reach areas. This crane has a maximum load capacity of 32 tons (70,500 lbs), with a maximum tip load of 7.2 tons (15,900 lbs) at full reach, ensuring it can handle the most demanding construction projects with ease.
Innovative Technology
At the heart of the J638PA is Jaso’s Optimus Line technology, an advanced package that enhances crane performance, comfort and safety. The J638PA’s design is the result of a collaborative effort between Jaso and its partners. Together, they have addressed a wide range of challenges—from technical to environmental concerns—creating a crane that is not only versatile and sustainable but also technologically advanced, offering high level of performance for construction professionals.
Environmental Stewardship
Jaso’s commitment to sustainability is evident in the J638PA’s design. The crane operates efficiently, with features that help minimize environmental impact while maximizing productivity. As part of Jaso’s ongoing efforts to reduce its carbon footprint, the J638PA is an eco-conscious solution for projects seeking to balance high performance with environmental responsibility. Ecomode
The New J165.8: Expanding the Flat Top Crane Range
The J165.8 is Jaso’s latest addition to its flat top tower crane product range, further solidifying the company’s position as one of the industry leaders in tower crane innovation. Unlike the J638PA, which has already made its mark, the J165.8 is set to be launched this year, bringing enhanced performance and versatility to the flat top crane market.
The J165.8 combines Jaso’s Optimus Line technology with a maximum radius of 60 meters. This model offers impressive lifting capabilities, including a max tip load of 1.76 tons at 60 meters in DR mode. When operating in SR reeving mode, the tip load can increase to 1.92 tons, with a maximum load capacity of 8 tons. The J165.8 is designed to meet the rigorous demands of modern construction projects, offering both power and precision in a compact package.
Tailored for Flexibility
The J165.8, like the J638PA, features a versatile boom system that starts at 30 meters and can be extended in 5-meter increments. The full boom configuration has a swing radius of just 12.8 meters, allowing for easy maneuverability in tight urban spaces. The crane also comes with lay-flat counterweight slabs for added stability, with an option for steel-framed counterweights for improved safety.
Advanced Hoisting Systems
The J165.8 offers two hoist options: a standard 33 hp hoist with a maximum speed of 66 meters per minute and an optional 60 hp unit capable of reaching 180 meters per minute. The crane’s hoist drums are equipped with Lebus-type grooving, allowing for rope capacities of 548 and 967 meters, respectively. These advanced hoisting systems ensure the J165.8 can handle a wide range of lifting tasks efficiently.
Versatile Tower System
The J165.8 uses Jaso’s standard 1.75 x 1.75-meter tower system, with sections available in 12, 6, and 3-meter lengths. This system allows for a maximum free-standing height of 50.1 meters. For taller projects, Jaso has developed the crane to integrate with the stronger 2.16-meter tower system to achieve higher hook heights.
Jaso offers multiple base options for the J165.8, including cross bases of 3.8m x 3.8m, 4.5m x 4.5m, and 6m x 6m, providing maximum hook heights of 42.8 meters, 54.7 meters, and 57.1 meters, respectively.
Innovative Cabin and Eco Mode System
The J165.8 will feature Jaso’s new ‘Horizon’ cabin, which will be presented for the first time at Bauma. This cabin is designed for maximum operator comfort and includes customizable settings, a tower crane diagnosis system, and Smartlink, Jaso’s cloud-based communication tool for remote crane management.
Additionally, the J165.8 is equipped with Jaso’s Eco Mode system, which allows the crane to operate at reduced power consumption. In Eco Mode, the crane uses 75% of its full power, and in Super Eco Mode, it uses just 50% of its power, allowing it to operate in areas with limited power supply. The Eco and Super Eco Modes reduce hoist speed during lifting but maintain normal speed when lowering the hook.
Efficient Assembly and Transport
The J165.8 has been designed for easier assembly and transport. The heaviest component, the slewing platform and tower head, weighs just 6 tons, allowing for reduced transport units. A full top kit for the J165.8 can be transported in just three lorries, simplifying logistics and reducing transport costs.
