The hydraulic emergency brakes of the S/DS range find their place on the low-speed shaft, as close as possible to the load to be stopped, on a disc usually flanged by the winch. The DS version is a classic two-half-calipers architecture, compatible with all possible disc thicknesses. The S version is floating, it follows the disc according to its imperfections, deformations or offsets. This property allows a reduced game setting, and in fact, an optimized response time. It is offered as standard with a support perpendicular or parallel to the disk; optional: without support or with a specific support.
