Spring Balancers (Retractors) with Automatic Retracting Function
Spring balancers (retractors) from Carl Stahl Kromer keep tools with a weight of up to 14 kg readily suspended within easy reach of the fitter, thereby contributing to a tidy workplace as well. Our spring balancers are designed so that the tool is automatically retracted to its initial position upon releasing it after use.
An automatic arresting mechanism (ratchet lock) is available in some models. It allows setting retraction stops to keep the load suspended at predefined positions. The stops are automatically activated if the working load (tool) is moved back slowly. If pushed back fast, the mechanism remains inactive.
As we put great stress on the quality of our products, all of our spring balancers have been life-tested and fully satisfy DIN 15112 requirements. They also comply with the relevant EC legislation, of course, as attested by the CE-mark. To round it all off, they also bear the „GS“ mark (safety-tested).
