The Bosch Rexroth RETURN BLOCK (3842518797) is an integral component designed to enhance the safety and functionality of lifting doors. This counterbalance deflection pulley system is engineered for applications requiring the controlled movement of doors, with an emphasis on safety and reliability. The system includes a deflection pulley and a control cable, which work in tandem to ensure smooth operation. The counterweight is adjustable and optimally operates within a cable duct, with the capability for the cable length to be tailored to specific requirements. Built to withstand significant usage, the RETURN BLOCK is rated for a service life of 50,000 actuations. It features profile finishes with M12 threading for securing the deflection pulley. A key safety feature of this product is its compliance with the Machinery Directive 2006/42/EC, which mandates the use of a back-up fall arrestor. In case of cable failure, the safety catch activates by jamming against a counterbearing, thus preventing the door from falling by wedging securely in the guide profile. The gap dimension between the body of the safety catch and the lateral guide profile is precisely 6 mm, ensuring consistent performance and safety. Each lifting cable requires one safety catch capable of handling a maximum load of 250 N and a minimum load of 25 N. For optimal functioning, it's recommended that the counterbearing (e.g., slider 3 842 530 303) be installed directly under the safety catch and as close as possible to it. The RETURN BLOCK can also be mounted on surface elements without a frame provided they possess sufficient transverse rigidity. Prior to installation and use, users are advised to consult the data sheet included with the product for detailed usage instructions. This ensures proper adherence to operational guidelines and maximizes both performance and longevity of this Bosch system component.
