Reliable fixation of plant components
Safety systems from LEANTECHNIK
Gravity-loaded machine axes without a safety guard can crash at any time and injure the operating personnel.
The stepless holding brake (SHB) and the mechanical arrest system (ASS) from LEANTECHNIK ensure that this cannot happen. They keep the axles in position reliably and with great force.
Three good reasons for LEANTECHNIK safety systems
TWO systems – ONE task:
The fixation of moving machine parts
The Machinery Directive stipulates precisely that machines and plants must be secured in the best possible way. Not only during operation, but also during standstill. LEANTECHNIK therefore has two braking and holding systems in its range that effectively prevent unintentional sinking or falling of moving machine parts.
Both systems can also be ideally combined with the lifgo® or lean SL® gear units.
Heavy loads firmly under control:
The Stepless Holdingbrake (SHB)
With the SHB, systems and system components can be secured against unintentional sinking during operation. The functional principle is simple and efficient: The clamping element of the brake is released by releasing the brake with the required operating pressure. Bleeding, on the other hand, causes the pretensioned disc spring to press against the clamping element and fixes the profile rail.
The stepless holding brake works according to the fail-safe principle. This means that it securely clamps moving loads even in the event of a sudden failure of the pneumatic system. The SHB can therefore also be used as a safety brake. However, the use of the SHB not only increases system safety. The process accuracy of the machine also increases, as the NC axis is additionally reinforced by the backlash-free clamping.

Increased plant safety
Increased process accuracy
High clamping forces thanks to pressure booster
LEANTECHNIK supplies the SHB in versions for 6 bar or 20 bar compressed air supply (with booster). This allows maximum nominal holding forces of 12,000 N or 30,000 N to be achieved.
The booster is always used when the pressure available in the compressed air system is not sufficient for the operation of the SHB. The mechanical increase of the pressure by the booster is considerably more cost-effective for the user than a general increase of the system pressure.
Also held securely at standstill
The Mechanical Arrest System (ASS)
LEANTECHNIK has developed the ASS safety catch especially for the locking of systems and devices in the dormant state.
When in use, its air cylinder is vented so that the toothed latch moves forward in the direction of the rack by spring pressure. This ensures that the system is lowered safely in creep mode. The process is only completed when the toothed latch is completely lowered into the rack. A second inductive switch signals this to the higher-level control, which then immediately stops the lowering movement.

Positioning with the ASS
In combination with lifgo® and leanSL® rack and pinion gear units, the locking device can also be used as a positioning unit for a fixed value.
