Cranes and hoists can add significant value to your production process. They improve efficiency, increase productivity, and enhance operator comfort. At the same time, they also present certain risks. Based on our experience, there are several important principles to follow to ensure safe operation. In this article, we'll explain how to work safely with cranes and hoists.
When operating a crane, there are several key points to keep in mind. Always position the crane directly above the centre of the load. This prevents the load from swinging when lifting begins. Lifting should always be a vertical movement—side pulling or lifting at an angle must be avoided. Prevent damage to the wire rope or chain, and always check that the emergency stop is functioning properly.
Operating Cranes and Hoists
Before operating a crane, first determine exactly what work needs to be carried out. Be sure to assess your surroundings as well. Consider how your lifting operation may affect the people and environment around you.
Once you have assessed the work area, check that all safety devices are functioning correctly. In particular, verify that the emergency stop is working properly. If the emergency stop is not operational, the crane or hoist must not be used.

Safe Working Position
To ensure your own safety during lifting operations, always wear the appropriate Personal Protective Equipment (PPE). In addition, choose a safe and strategic position in relation to the crane or hoist and the load.
If a chain or wire rope fails, the load will not necessarily fall straight down. It may swing or fall at an angle. Always take this into account when positioning yourself.
Most importantly, no one must ever stand or walk beneath a suspended load—even when the crane or hoist is not in operation. Always move forward while guiding a load and maintain a safe distance. Never walk backwards while moving a load.
Pendant Control or Radio Remote Control
Once the work area has been prepared, you can begin operating the crane. This is typically done using either a pendant control or a radio remote control (RRC).
Most crane controls offer multiple speed settings. Always start lifting, trolley travel, or bridge travel at a low speed. Once the movement is stable, you can increase the speed if necessary.
Starting slowly helps prevent shock loading on the lifting equipment and avoids sudden movements of the crane. A controlled start is not only safer but also more efficient.
Lift Smoothly and Maintain Control
When working with cranes and hoists, always perform lifting operations in a smooth and controlled manner. Carry out one movement at a time to maintain full control and a clear overview of the operation.
Never lose sight of the load while lifting or moving it. This is essential for your own safety and that of your colleagues. Good communication is equally important. Make sure everyone involved knows what will happen before the lift begins.
If the load is large and requires multiple people to guide it, consider using tag lines. These allow operators to control the load while maintaining a safe distance.
Lift Vertically Only
Cranes and hoists are designed for vertical lifting only. Never attempt to drag or pull a load sideways beneath the crane.
Lifting at an angle or dragging a load can damage the wire rope and the rope guide—both critical components of a wire rope hoist. The rope guide ensures the wire rope is wound correctly onto the drum. Improper use can easily damage these components, making continued operation unsafe and significantly increasing the risk of failure.
