Due to industry demand, Shuttlelift has added an exciting new model to its product lineup. The SB 120 single-beam, single-hook, rubber-tired mobile gantry crane is the Sturgeon Bay, Wisconsin-based manufacturer’s largest SB Series crane to date; it shipped the first two SB 120s to a customer this past December.
Shuttlelift announces the new single beam gantry crane, dubbed the SB series. With manufactured components such as bridge beams and wind tower components being built to longer lengths, it has become commonplace to transport these items by tandem lifting. With two cranes required for this lifting technique, the Shuttlelift SB series is an effective solution when used in tandem. The Shuttlelift SB series can even be used in conjunction with a customer’s existing conventional rubber-tired gantry crane, regardless of brand.
Two successful options for Shuttlelift’s SL and ISL gantry cranes have been perfected by its design engineers; namely, an innovative wheel jacking technique and an automatic variable throttle (AVT) system.
Kurt Minten, director of industrial sales, explains, “This exciting new wheel jacking application is available on all units with a cantivered wheel frame. Basically, a self-contained motor, pump and hydraulic reservoir can be hooked up to the crane’s battery, a stand-alone 12v battery or the battery of a service vehicle. The system will drive the pump, actuating a hydraulic cylinder that is bolted to the wheel frame, raising the wheel clear of the ground enabling the flat tire to be changed. The beauty of this system is that tires can be changed in confined spaces where access with cranes or large forklifts is difficult.”
Built-in programming of the AVT automatically adjusts the engine speed to produce sufficient power to carry out the task in hand. For example, depending on what function the crane operator selects, whether that’s the use of only one hoist or hoist and traverse operation, then the AVT will only produce sufficient rpm to accomplish that selected activity and will always return to idle once the task has been completed. With the AVT option, engine rpm management management does not require any operator input. There are no manual processes to be completed before a significant reduction in fuel consumption is immediately realized.
Automatic Variable Throttle (AVT) is now available as an optional extra on all Shut-tlelift ISL and SL gantry models. Factory testing of the AVT has demonstrated that, depending on the duty cycle, potential fuel savings per machine can be as much as $7,000 per year compared to the standard throttle system. With the AVT option, engine rpm management does not require any operator input. There are no manual processes to be completed before a significant reduction in fuel consumption is immediately realized. The built-in programming of the AVT will automatically adjust the engine speed to draw only sufficient power to carry out the task at hand. For example, depending on what function the crane operator selects, whether that is the use of only one hoist or hoist and traverse operation, then the AVT will only produce sufficient rpm to accomplish that selected activity and will always return to idle once the task has been completed.
