Parallel key for Demag AC80-1

The parallel key, part number 758 117 73, serves as a mechanical connector within the Demag AC80-1 all-terrain crane. It is installed to lock rotating elements such as gears, pulleys, or couplings onto a shaft, preventing relative movement between the parts. By creating a secure mechanical link, the key allows for the effective transfer of rotational force throughout the crane's power transmission systems.

This component is specifically engineered for fitment within the Demag AC80-1 model. The key is designed to sit within a machined slot, ensuring that the connection between the shaft and the attached component remains stable during operation. Proper installation of this part is necessary to maintain the alignment and synchronization of the crane's drivetrain assemblies.

In heavy machinery, parallel keys act as the primary interface for torque transmission between shafts and hubs. They are engineered to withstand the shear forces encountered during the operation of winches, slewing drives, and other rotating equipment. By ensuring a tight fit within the keyway, these components prevent slippage and protect the integrity of the drive assembly.
