Moment couplings are specifically designed to handle both the required application torque and the bending moment forces of the suspended weight of a drive package, including the gearbox, motor, high-speed coupling, and swing base. Highly engineered using 4140 alloy steel and Grade 8 bolts, this design allows for an alignment-free drive by eliminating the time consuming process of aligning the gearbox assembly to the head pulley shaft.
