For more than half a century, the US company SHUTTLELIFT has been engaged in the development and production of high-tech mobile portal cranes. The company offers portal cranes for such industries as aerospace, construction, energy, port logistics, shipbuilding, with a lifting capacity of 15 to 200 tons. Micro-mobility, high-precision positioning, automatic leveling by room height, makes SHUTTLELIFT indispensable for many applications in various areas of human activity.
The maximum lifting capacity of the new Shuttlelift CD5520 crane is 18 tons. It is equipped with a 4-section 16.6-meter telescopic boom, which has separate hydraulics on each section. When the boom is fully extended, its maximum head height reaches 26.2 meters.
The new product will replace its predecessor, the CD5560B model, having a number of new features compared to it. Thus, for the first time, two jib configurations will be offered on the Shuttlelift line of machines: a fixed 4.6-meter extension and a folding telescopic jib, the length of which can vary from 4.6 to 7.6 meters.
With an overall length of 7.1 meters and a width of 2.3 meters, the crane feels great in cramped conditions, and its overall height of 2.5 meters allows working inside production facilities. In addition, the CD5520 features a crab mode and a self-leveling boom head that can be set to five different positions at angles from -30° to +50°. This gives the machine high maneuverability and flexibility when positioning the load in a congested space.
"The crane's size makes it ideal for use in automotive and machine tool plants, shipyards, refineries and other sites where space is limited," says McCallum.
Other features of the CD5520 include a two-speed winch, a 3.3-liter Cummins QSB diesel engine and an ITL powershift transmission. In addition to the crab mode, there are steering modes that provide for both two-wheel and four-wheel steering. While previous industrial crane models were generally designed for hard-surface sites, the new all-wheel drive CD5520 can now be used on rough terrain, such as gravel or muddy ground, the company says.
The completely redesigned cabin features a new instrument panel with an automotive-style display and sealed keys. In addition, the driver now has four proportional joysticks to control load-sensing hydraulics, making boom telescoping, lifting, platform rotation and other operations smoother. This is achieved by using a single-piston hydraulic pump instead of the four-gear pump found on older models.
Much attention has been paid to safety issues. For example, headlights, brake lights and work lights are now equipped with LED lights for better visibility. An outrigger control system is installed with an indication of the full extension of the supports, at which the corresponding lights on the instrument panel light up. Larger tires have a more aggressive tread and are designed for increased loads. For the convenience of the operator, the steering wheel can be folded down.
