Traction Element (Chain/Belt)

A traction element in elevator bucket conveyors refers to the continuous loop component—typically a chain or belt—that transmits mechanical power from the drive unit to the buckets. It provides the necessary tensile strength and flexibility to move buckets vertically or horizontally while maintaining precise alignment and synchronization. Chains offer high strength and durability for heavy-duty applications, while belts provide smoother operation with reduced noise and maintenance requirements.

The traction element operates on the principle of continuous mechanical engagement between the drive sprocket/pulley and the element itself. As the drive unit rotates, it pulls the chain or belt, which in turn moves attached buckets along the conveyor path. Chains use positive engagement with sprocket teeth, while belts rely on friction between the belt surface and pulley. Both systems maintain tension through take-up mechanisms to prevent slippage and ensure consistent bucket movement.
