The Bosch Rexroth RETURN BLOCK (3842555566) is a robust and reliable counterbalance system designed for lifting doors, ensuring smooth operation and enhanced safety. This system includes a deflection pulley and control cable that work in tandem to facilitate the effortless lifting of doors, with a counterweight that is individually adjustable to accommodate various door sizes and weights. The counterbalance system boasts an impressive service life, capable of numerous actuations, highlighting its durability and long-term performance. This model features profile finishes that allow for secure mounting of the deflection pulley, ensuring stability and operational integrity. A key safety feature of the RETURN BLOCK is its integrated safety catch. This critical component acts as a fail-safe by wedging in the guide profile in case of a cable breakage, preventing potential accidents by stopping the door from falling. The gap dimension between the safety catch body and lateral guide profile is meticulously measured to guarantee proper function. Each cable requires one safety catch that can handle a maximum load specified by the manufacturer, with also a minimum load requirement for optimal performance. It's recommended that the counterbearing be installed directly under the safety catch for best results, contributing to the overall stability of the system. Installation instructions are provided with detailed notes on usage to ensure correct setup and operation. The package includes all necessary fastening materials made from galvanized steel in signal gray color for both durability and aesthetic integration with various environments. Recommended accessories include cable ducts, sliders, and additional safety catches, while required accessories encompass counterbalance weights tailored for square profiles. In summary, this Bosch Rexroth RETURN BLOCK is an essential component for any lifting door mechanism seeking reliability, customization through adjustable weights, longevity through high actuation capacity, and most importantly—safety through its innovative safety catch feature.
