Operating Conditions The gearboxes are designed for use at ambient temperatures of between -20°C and +40°C. Environmental influences such as salt water, salty air, sand, dust, pressure, heavy vibrations, extreme shocks and ambient temperatures, aggressive fluids and the like may affect the function of the gearbox. All such conditions must be specified so that the gearbox can be designed for safe operation. Gearbox Design The gearbox design is based on many years of practical application experience. The maximum output torques T2 max indicated under technical data for crane applications relate...
