Crane Motors

Maximum Power Even in Turbulent Applications

Crane motors are often exposed to extreme weather conditions – as well as being subject to high operational requirements. They have to withstand high humidity, salty air and high wind speeds while ensuring a high overload capacity and a wide speed control range.

Crane Motors – a Brief Summary of Their Strengths

Increased efficiency
For ambient temperatures up to 50 °C, optionally also higher – Protected against humidity up to 100% and salty atmosphere

More power

Torque reserves for high surge loads and an overload capacity up to 230% – used as accelerating drives, our crane motors master any situation.

More flexibility

Using a generously dimensioned terminal box, corrosion protection inside the motor and optionally available rugged mounting feet and flange manufactured from a torsionally stiff spheroidal graphite iron – our crane motors can cope with any task.

Crane Motors – Typical Uses

The rugged gray cast iron motors are particularly suitable for rough lifting gear operation under adverse operating conditions – for indoor and outdoor application, e.g. in harbour facilities for rubber-tyred gantry, rail-mounted gantry, automatic stacking cranes.
