Whether it is called an “Overhead Crane” or a “Bridge Crane”, it can be found in a multitude of industrial environments, ranging from steel, automotive, power generation, pulp and paper to name just a few. The typical overhead crane consists of parallel runways with a traveling bridge spanning or straddling the gap. A hoist, mounted on the bridge is the lifting component of the crane.
Unlike mobile or construction cranes, overhead cranes are typically used for manufacturing or maintenance applications, where efficiency and downtime are critical factors.
The origin of today’s industrial crane can be traced to the Ancient Greeks, who in the 6th Century BC, developed a winch and pulley-hoist system to replace a series of ramps as the main means of vertical lift.
Although considered a mature product, the Gear Coupling not unlike the cranes they are used on, are being asked to do more while remaining true to the industry standards necessary for form fit and function. With the launch of the HercuFlex™ gear coupling product line in late 2014, Lovejoy has redefined and reinvented the gear coupling. Crane and hoist designers can look to Lovejoy for a new “Industry Standard” that offers increased torque and bore capacities combined with a design that increases service life while still retaining interchangeability within existing gear coupling sleeve flanges per AGMA standard dimensions. Simply put, the increased capacities will allow designers to maximize their system design or downsize the coupling to gain cost reductions without sacrificing performance.
