KROMER Spring Retractors, available from Millsom Materials Handling , are designed in such a way that retraction force increases as the cable is extended. As a result, after use, the attached tool is returned to its starting position by the retractor, leaving the workbench free for other tools or equipment. These retractors have lifting capacities ranging from 0.3kg to 10kg.
Most versions of both retractors and balancers are available with an automatic arresting mechanism. This mechanism stops the retraction process in any required position, provided the tool is retracted slowly. If the tool retracts rapidly, the arresting mechanism does not operate. This feature is useful, when there is a need to prevent the tool from returning to its original starting position.
