Precise rotation speed feedback for crane applications

Incremental encoders for feedback at hoists and hoist drives

Product combinations of encoder and speed switch are ideal for crane winch applications. Mechanical centrifugal switches and electronic, programmable speed switches detect any winch overspeed and prevent damage and personal injury.
