About Siemens Crane Duty Motors

Crane and hoisting equipment requires motors that can handle frequent starting, stopping, reversing, and acceleration without compromising dependable operation. Siemens Crane Duty Motors are designed for applications where these demanding operating cycles are part of everyday work.

We Tech Power Solutions Ltd is an authorised dealer of Siemens Crane Duty Squirrel Cage Motors, offering a range from 0.18 kW to 200 kW, equivalent to 0.25 HP to 270 HP. These three-phase motors operate at 415 V and 50 Hz and are available in 1500 RPM and 1000 RPM configurations.

Designed with a robust cast-iron body, these motors support S3, S4, and S5 duty classifications. Depending on the application, CDF ratings of 25, 40, and 60 are available, along with configurations designed for frequent starts per hour.

Built for Frequent Starts, Stops and Reversals

Crane motors work differently from standard continuous-duty motors. Lifting and travelling mechanisms may repeatedly accelerate, stop, reverse, and restart during a single operating cycle.

These motors are designed for applications requiring high starting torque with controlled starting current. Their operating characteristics support rapid acceleration and the stresses associated with frequent switching and reversals.

The appropriate duty classification and CDF rating should be selected according to the actual operating cycle, number of starts, load characteristics, and mechanical requirements of the crane or hoisting system.

Where Are Siemens Crane Duty Motors Used?

Typical applications include:

• EOT and overhead cranes

• Hoists and lifting systems

• LT and CT crane drives

• Material-handling equipment

• Conveyors

• Winches

• Loaders and unloaders

• Weirs and sluices

• Lift-duty machinery

• Auxiliary drives in rolling mills

These motors can be used across industries such as steel and metal processing, manufacturing, warehouses, ports, infrastructure, engineering, and material-handling operations.
