High Pressure Control Blocks
The crane is controlled by the high pressure control blocks M4 12, 15 and 22 in disc design. These blocks operate with load sensing to save energy. For different loads and where a number of actuators are operated at the same time, load pressure compensation ensures that the same speed can be maintained. The blocks can be operated mechanically, hydraulically, electro- hydraulically or with on-board electronics. In addition, the M7 22 monoblock with its load-independent flow distribution ensures that all the actuators can continue to run at a proportionally reduced speed even where the volume flow is insufficient.

Winch control block (Type YM-WCB16)
Whether it’s a towline winch with high unladen rope speed, a mooring winch with automatic rope tightening or an anchor winch with an initial break-away torque increased by 50 %: the WCB, with its seawater-resistant deck construction and modular design, caters for every eventuality, both on its own or when
used in combination. The WCB also features a choice between manual, hydraulic or electric controls.

Winch control block (Type WCB15)
The raising and lowering functions,the valves for load sensing and the automatic holding brake release are standard features in the basic version. Furthermore, the pressure scale guarantees load-independent behavior and thus an even windlass
speed. Control is effected mechanically via hand lever, electrically and hydraulically.

Load-Sensing M4-15 Control Block for Maritime Applications
Thanks to their modular and compact construction, Rexroth M4 control blocks are used in the most diverse applications. They can be used to control travel drives in open circuits as well as for precision and stable control of work movements. The M4 valve block is giving you furthermore the option of actuating single consumers proportionally and with high sensitivity. And this can be done mechanically or hydraulically depending on requirements. The M4 module is so flexibly constructed that all types of actuation are possible individually or combined. Beside other applications, the control block M4 is used in the new Rexroth-winch control block.

Custom Control Blocks
Wherever the wide range of series control blocks does not suffice for a particular control system or does not ideally cover the functions required, Rexroth also offers customer-specific solutions. Working together with our engineers you will be able to find exactly the right control block for your application.

MSC Slewing gear control
You can control the sequence independently of the supply with this compact control block, as well as configuring the deceleration of the slewing gear to suit your individual application. Further integrated functions permit both the control of the holding brake and the proportional activation of a dynamic slewing gear brake.
