The new rubber-tired, single-beam SB Series gantry cranes concentrate loads directly under the frame, eliminating potential stability concerns operators might encounter with rough-terrain or crawler cranes, a reach stacker, or forklift. With a material-handling advantage based on what Shuttlelift officials note is fundamental physics, the model also features a) an articulated pivot trunnion, which enables the frame to flex with uneven terrain and eliminates additional strain on the machine’s structure; and, b) planetary drives, ensuring the equipment will move smoothly under acceleration or deceleration–augmenting operator’s precise control of load.
The SB Series can manage 30- to 100-ton loads and suits single-point picks such as septic tanks and modular precast cells. To do the same with an ISL gantry, for example, you would need a spreader frame to bring the unit to a single pick point, says Shuttlelift Director of Industrial Sales Kurt Minten. The single-beam gantry, on the other hand, is ideally suited for this sort of task. These principles apply to tandem–increasingly common with precast components being fabricated in longer lengths–as well as single-point pick applications, he adds.
If youÌre using the single-beam gantry crane in a tandem pick, as with bridge beams, youÌll receive the same benefits, explains Minten. Plus, SB Series cranes can be used in conjunction with a conventional rubber-tired crane that may already be on site, regardless of brand.
Compact size and smooth maneuverability position the SB Series to act as an alternative to a permanent overhead bridge crane, maximizing use of indoor and outdoor space. Instead of spending significant resources on a building’s foundation and structure to accommodate an overhead crane, then investing in separate outdoor lifting solutions, Minten notes, a plant can use a single-beam gantry crane both indoors and out.
