Carl Stahl Kromer

Safe and ergonomic workplace design

How the Kromer tool retractor works:

Carl Stahl Kromer Spring balancers, often called retractors, are designed in a way that the retracting force increases with increasing cable extension. Thus, the working load (tool) is automatically retracted to its initial position after use. The advantage of spring balancers is, that the work place is kept free for other tools or devices, which also increases ergonomics and safety. Precise operation is assured as the retraction force increases gradually and very smooth.

Important for product selection:

Make sure, that the load to be balanced is within the load range of the balancer, while the working stroke should be less than the maximum cable travel. Our spring balancer range is uo to 14 kg.
