Tower Crane Lever Shaft Coupling

     The specific functions of the coupling of CTECH Machinery SDN BHD tower crane include:
     Power transmission: Efficiently transmit the rotational motion and torque of the prime mover (such as an electric motor) to the working mechanism, ensuring the normal execution of lifting, turning, amplitude changing, or walking actions.
     Displacement compensation: Absorbs axial, radial, and angular relative displacements caused by manufacturing errors, installation deviations, foundation settlement, or thermal deformation to avoid premature bearing wear due to hard friction.
     Buffer vibration reduction: By absorbing the impact vibration generated by starting, braking, or sudden load changes through elastic elements (such as rubber, diaphragm, etc.), the transmission stability is improved and the risk of structural fatigue is reduced.
     Overload protection (some types): Safety couplings (such as shear pin type) actively disconnect in the event of severe overload to prevent damage to key components such as motors and reducers.
     Note: Due to heavy loads, frequent starting and stopping, and susceptibility to wind loads, flexible couplings (such as toothed, diaphragm, and elastic pin) are usually preferred for tower cranes. Rigid couplings are only used in high-precision and impact free situations; The safety coupling needs to be regularly inspected and replaced according to regulations, and cannot be used as a regular buffer for a long time.
