The Lift Arm Hold Key takes the form of a rectangular or square-shaped metal piece. It fits into corresponding keyways machined on both the lift arm and the shaft. It prevents relative movement between the lift arm and the shaft, ensuring the lift arm remains aligned and stable. It enables the transfer of power and motion, allowing the scarifier to effectively penetrate and remove materials from the surface.Attributes:• Provide a precise fit and prevent rotational movement or slippage• Offer excellent mechanical strength, durability, and resistance to wear and deformationApplications:The Lift Arm Hold Key is used to secure the lift arm to the shaft, ensuring proper alignment and stability during scarifying operations. It should fit snugly into the keyway, ensuring a secure and precise connection between the lift arm and the shaft, and also used in the blade lift gearbox.
